Land Use
by Anonymous
"Douglas fir and lodgepole pine grow best in lots of sunlight. Although I know that clear cutting can cause some serious problems and may not look very good on the landscape, I want the eastern part of the forest to grow back in lodgepole pine and Douglas fir after the area has been logged, so I want to clear cut the mature fir and pine. The US forest Service has regulations which specify (unless exceptions are made) the size of clear cuts in different forest types. Because of a variety of factors, I want to limit the size of clear cuts in this forest to a maximum of 40 acres.
On the other hand, the Engelmann spruce, which grow on the northern and western sides of the forest, reproduce best in somewhat shady conditions, so I have decided to selectively cut it. First, we'll harvest only older, mature trees and diseased trees. Then we'll cut out some of the very small trees so that other small trees have a better chance to grow.
In another 20 years, I will have a very good stand of Engelmann spruce, which can again be selectively cut to allow other trees to grow. I must clear cut a total of at least 500 acres or selectively cut a total of 800 acres each year, or the timber harvesting won't be economically worthwhile, but I can combine clear cutting and selective cutting. A study of logging costs, special equipment, road building and other economic factors lead to the following set of alternatives for harvesting timber:
Recreation Specialist
I would also like to develop a hiking trail which crosses the river in the middle of the forest and goes up to the top of Elk Mountain. The trail will go down the other side of the mountain and then back to the campground. I haven't decided where to put the ski trail yet. I want to make sure that large clear cuts will not be visible from anywhere on the trail at the top of Elk Mountain. clear cuts that follow the natural contours of the land and that cover less than 40 acres might be all right.
In addition to the 50-acre campground, I want to develop a 30-acre campground in another part of the forest where people can be close to the river for trout fishing. I must also build a road into a parking area along the river for trout fisherman and canoeists. This road can't be built in steep areas of the forest because erosion from the road may be too great. I must find a gentle sloping area for this road. I feel that logging operations should not be visible from the road either, because they will adversely affect the enjoyment of the visitors to this beautiful forest.
Wildlife Biologist
Sometimes logging small tracts of land increases the amount of forage available because it allows shrub and young trees to grow. It also creates more edges which are very important in managing habitats. An edge is a place where two different habitats, such as meadow and forest, meet. the abundance and variety of plants found in edges is greater than that in one general habitat area, and thus the variety of wildlife is also greater.
My data show that if we clear cut four or five 25-acre tracts on the eastern side of the forest, more food will be available to the deer. We can't, however, clear cut more than ten 25-acre sections in any one year because this would provide too much food. The deer population might increase too much and damage the forest by feeding on valuable young timber trees.
The eastern part of this forest is an excellent habitat for woodpeckers. The old forests, such as the Douglas fir and lodgepole pine stands in that area, contain standing dead trees that the woodpeckers need for building nests and finding insects to eat. It is important to maintain part of these older stands to keep some of the rotting trees there for the woodpeckers and fallen trees for ground squirrels and other small animals.
Watershed Manager
We also should not log along the river. The cottonwoods that grow along the stream protect it, and they would not make good lumber anyway. It is important to leave these areas undisturbed. If the forest remains a forest, the city of Cleveland Falls will have a steady supply of water. However if 50 percent of the forest acreage is cut, too much water will run off too quickly. Up to 35 percent of the forest could be selectively cut without affecting the watershed. Some parts of the forest can be logged without seriously affecting the watershed, but these parts should not be close to the river. I recommend that clear cutting not be done on sections larger than 30 acres.
We also need to monitor the number and location of roads because they are a major source of erosion if they are not properly made. Therefore, I think we should only have two roads on the western side of the forest and two on the eastern side to use in logging. I have placed an X on the map in each of the 100-acre tracts which I do not think should be logged at all. The remainder of the forest could be logged without causing severe erosion, but I would prefer selectively cutting or clear cutting in 30-acre plots.
Are there any Clear Cut Answers?
Names _______
You have each been given a card explaining your role in developing a management plan for this forest. Work as a group to answer these following questions. Then, use the information to develop your management plan. Each person in your group will be able to answer some of the questions from the information on his or her role card, or from the forest map.
Lesson V - For the Enjoyment of Future Generations
Lesson I - Who Decides?
(Grades 6-12 , Duration: 3-5 class periods plus research time)
Materials: Prior to this activity the teacher should research the phone
numbers and names of contact personal of local agencies that will be used
by the students to answer issue questions.
Skills:
-problem solving
-communicating
-decision-making
Objectives: By the end of these investigations, your students should be
able to:
1. recognize the special interests of some organizations and agencies involved
in making decisions;
2. locate laws, ordinances and information that apply to particular environmental
issues;
3. list five different ways people use land;
4. identify and follow actions related to a specific environmental issue.
Background:
Land use planning is the process of shaping the use of land for different
purposes based on the needs and resources of the area and the characteristics
of the land. It can be considered an attempt to predict the future and plan
the best use of land to accommodate future needs and growth. Most communities
have some kind of system, such as a city plan, a set of zoning regulations,
or ordinances prohibiting or permitting certain kinds of activities. This
system may regulate how land is used, where parks and factories can be located,
or where highways can be built. Because the land available to meet the needs
of an increasing population has remained the same, the demands placed on
it have increased, and thus comprehensive land use planning has become more
important.
Setting the Stage:
To help your students learn some of the ways they use land, guide them in
listing the services and places their families use, such as grocery stores,
clothing stores, electricity, playgrounds, telephone communication, swimming
pools, factories, dentist offices, libraries, hospitals, and roads. Students
could also gather pictures and show these places on a collage. These questions
may help them start thinking about land uses:
1. What recreational facilities do you use?
2. Where do your parents work?
3. Where do you shop?
4. What items do you own? Where did you get them? Where do you take them
for service?
5. Where is your food grown?
6. Where do you live?
7. Where does your electricity come from? How does it get to you?
8. Where is your water obtained and/or purified?
When your students have an extensive list of places, work with them to group
the items on the list into categories. Your students will probably suggest
zoning categories such as commercial, industrial and recreational.
If you can, take a short walking tour of the area right around the school.
This can be particularly effective in urban areas. Do you see a variety
of land uses? How does the location of the school relate to the adjacent
land use? Now your students are ready to explore the land use planning process
within your community.
Procedure:
1. Explain to your students that they will be contacting local agencies
to find out the answers to land use questions. These county or municipal
offices are responsible for making decisions that many people don't think
about but are very important in our daily lives.
2. Assign each of your students one of the problem questions listed below.
Choose questions based on the agencies or resources you have made prior
contact with. (This is not an exhaustive list. The class may be curious
about other aspects of community services and regulations and students may
want to answer their own questions, as well.)
a. How many building permits were listed last month in your community/county?
How many were commercial? What agency issued these permits?
b. How many fire hydrants are in your community/county? Where did you find
out how many there are?
c. How many sanitary landfills are in your community? What agency manages
them? What company or agency collects the garbage that goes into the landfills?
d. How many sewage treatment plants exist in your county? Are the treatment
plants in compliance with Federal regulations? Are they adequate to serve
the community's needs?
e. Which land use category (residential, commercial, industrial, agricultural,
etc.) covers the largest land area in your community/county?
f. How many zoning categories are there in your community/county?
g. How many parks are in your community? What agency is responsible for
managing them? Where are the parks located? Are they evenly distributed
throughout the community?
h. How many members sit on the zoning board? Are these zoning board members
appointed, elected or paid employees?
i. How many public buses are owned by your community/county?
j. How many miles of county-maintained roads exist?
k. How many miles of city/community-maintained roads are there?
l. Is there a community/county land use plan in existence? Where was it
written?
m. Is there a planning commission in your community? Is it different than
the zoning board? How large is the commission and are the members appointed,
elected or paid employees?
n. How early can construction workers star using noisy equipment in your
community? Who enforces this regulation?
o. At what hour can phone, gas line or utility repairmen start working in
residential areas?
p. How early can airplanes start taking off and landing at the nearest airport?
How late can they operate?
q. What does the "hospital zone" sign mean to trucks?
r. What citizen action committees or organizations exist in your community?
3. You may want to make the initial contact with local resources and agencies.
Then allow your students to decide, with guidance, what questions to ask
and how to ask them. Allow your students plenty of time to gather the answers
to their questions.
4. When students have gathered their information, have them share the processes
they went through to answer their questions with the rest of the class.
a. Who had to call or contact the most people before getting the needed
information?
b. Which student had the most difficult time obtaining the information?
c. Who had the easiest time?
5. Once the questions from Procedure #2 have been answered, use them to
make an organizational chart of the planning system in your community. You
can then use the chart to follow zoning variances and building permit requests
through the approval system and to show the relationships among the various
agencies responsible for land use planning in your community. You should
also be able to use the chart to identify the steps in the process where
citizen action is most effective.
6. Now that your students have gathered information about their local planning
authority, they should explore the impact land use planning has on private
rights. People have traditionally been able to do almost anything they wished
with their land, but this is no longer true in some places. Your students
should solve the problems below, using the information they have gathered
and the agencies they have identified to help them find the answers. (They
may want to change the problems slightly to make them more specific to your
own community.)
a. A man who owns land in a residential section of town wants to build a
fast-food restaurant on the land. - Can he do it?
b. A cattle rancher owns land close to a small group of homes. The smell
from his feed lots is bothering the residents. What can they do about it?
c. A developer wants to build an apartment building on the lot next to your
home. You are afraid it will lower your property value. Can you legally
stop or change the developer's plans?
d. You bought a house on a hillside because it has a wonderful view of the
river valley below. Recently, construction was started on a high-rise apartment
building just down the hill that will obscure your view of the valley. Can
you legally stop or change the plans?
e. The local electric company plans to build a nuclear power plant in your
community. Citizens do not want it there. Can they stop the construction?
f. Your city is growing rapidly and your street is now being used by commuters
to get to work. It is noisy and dangerous for young children. Can the residents
do something to stop the use of the street by commuters?
g. The State Highway Commission is building a new highway and has bought
most of the houses and lots on which the highway will be built. One family
does not want to sell and has refused the state's offer. Who has the legal
right to determine the land use, the state or the citizen?
h. The county wants to widen your street to a four-land road because of
increased traffic. You don't want the street widened because it will increase
the danger to the children in your neighborhood. What can you do?
i. The county wants to sell some land which was supposed to be developed
as a public park. The local citizens want the land to remain county property
and to be developed as a park. Can they stop the sale?
Evaluation:
1. What amount of influence do students think the private citizen has on
land use decisions, especially regarding his or her own land? What concessions
must one make when he or she lives in a heavily populated area? In a small
community?
2. Which agency is most influential in planning land use within your community?
3. What environmental issues were identified having to do with land use
planning in your local community? What special interest groups have become
involved in the issues?
4. How easy or difficult is it for the individual citizen to have input
into land use decisions in your community? Could the process for citizen
input be improved, and if so, how?
Enrichment Projects:
1. If your students have identified a local environmental problem, explore
the issues involved in solving the problem and the possibility of your class
helping to raise funds or do something more direct to help solve it. They
could hold a benefit costume dance at which students dress in costumes depicting
our most serious environmental problems. Contests can be held at the dance
for the most realistic costume, the costume that most nearly shows what
considerations are involved in solving the problems or perhaps the costume
which most clearly or cleverly shows the stand taken by a particular interest
group. The money that is raised can then be used to help solve the problem
in the local area.
2. Land Use (zoning): Identify zoning areas and their restrictions in your
communities, then draw a map illustrating them and add the man-made structures
or elements within them. Do they all meet the zoning restrictions for their
areas?
3. Zoning Variance: Identify any structures that are inconsistent with zoning
regulations and discover the terms under which their construction was approved.
Lesson II - Who Planted the Maple on Elm Street?
(Grades 6-12, Duration: 3-5 class periods)
Materials:
-tree identification guides
Skills:
-observing
-measuring
-recording
-classifying
-analyzing
-communicating
-hypothesizing
Objectives: By the end of this investigation, your students should be able
to:
-give 3 examples showing how two species of trees are similar and dissimilar
-compare 2 different groups of trees and identify the trees which are of
the same species
-list 5 benefits provided by trees
Background:
Sampling provides an exciting introduction to statistics. Your students
should have the opportunity to explore statistics though this and by other
sampling experiments. The teacher and students should think about the following
questions and issues through out the investigation. Is there a relationship
between the size of the sample and the reliability of the sample? The students
may want to design a plan to prove the reliability of their sampling technique.
Setting the Stage:
Your students must know how to take a sample in order to conduct a community
tree inventory in this investigation. Use this exercise to prepare them
to develop a sample technique and to show them that samples can give approximate
population counts if the samples are large enough. Left-handers and right-handers:
how many of each?
1. Count the number of left- and right-handers in your class and in four
other classes. What is the ratio of left-handers to right-handers? What
percentage of the total population in the class is left-handed?
2. Have students suggest several methods to pick specific groups of students
and count the left and right-handers in the group. For example, pick a group
of all:
a. students whose last names begin with a, d, r, u, w;
b. students sitting in the 2nd and 4th rows;
c. students whose birthdays are in June, April, July and October.
By experimenting with sample sizes, discover how large and sample needs
to be to give an accurate estimate for the total population.
3. What is the ratio of left-handers to right-handers in each group? Is
it similar to the ratio you found when you counted every student? They should
find that:
# of left-handers in total class # of left-handers in a small sample
# of students in the class = # of students in the sample
4. Now, pick some other characteristic (such as eye color) and take several
samples first. Predict the number having that characteristic in the class
or classes as a whole. Then count all the students and find out if your
sample provided an accurate estimate. How do the class results compare with
national or world statistics for those characteristics.
Procedure: Now your students are ready to develop a sampling plan in order
to conduct an inventory of the trees in your community.
1. Define the boundaries of the inventory area. Perhaps 4 streets that define
the neighborhood.
2. Develop a sampling technique to count the trees within the boundaries
you have selected. Will you count the trees in the yards of every 2nd or
6th house on each street? Will you count all the trees on every 2nd or 4th
street, or perhaps just the trees growing along city streets? Let your students
set the boundaries and develop their own sampling plan. When they begin
the inventory, they may well discover that they have tried to do too much
or too little with their original plan and will have to try a different
technique.
3. Divide the inventory area into study sections and assign each section.
4. Students must be able to identify the trees in their sections. Provide
each student or group with several identification guides. A local nurseryman
or naturalist may also be able to help your class with identifications.
5. Each student or group should gather the following information about their
study section. When the information is compiled, it will be the basis of
the class' community tree inventory.
a. What is the total number of trees in a random sample of a study section?
Based on the random sample, what is the total estimated number of trees
in the study section?
b. How many of each species of tree are there in a random sample of a section?
Based on this, what is the estimated number of each species in the entire
study section?
c. What is the most common tree in the study section?
d. How many species of ornamentals are in the study section? In the schoolyard?
(Some ornamental trees may not be native to your area and may not be included
in regional identification guides. Prepare your students for this and work
together to identify ornamentals.) Students could ask a local nursery or
the homeowner to identify particular trees for them.
e. What is the most common tree in the schoolyard? How many dead trees are
in the study sections? How many trees have been planted in the past three
years? What kinds? You may want to ask other similar questions in order
to develop a more detailed survey of the trees in your inventory area.
f. Find the tree with the largest circumference in the study section. Use
a piece of string to measure the circumference at chest height and use the
formula x d = c to find the diameter of the tree. = 3.14 so the diameter
can be found from: d = c / or d = c / 3.14.
g. Make observations about the animals, including insects found near or
in the trees. If students wish, they can use field guides to identify the
animals.
6. When the data from the individual study sections has been compiled, students
can estimate the total number of trees and the number of kinds of trees
found in the entire inventory. For example, if a given group of students
counted the number of trees on every other street in their section, they
can now double this number to obtain an estimate of the total number of
trees in their study section area. Adding up the estimated total number
of trees in each study section will give you the estimate of the total number
of trees for the entire inventory area. (See sampling techniques as outlined
in Setting the Stage).
Evaluation: When the community inventory is complete use these questions
to analyze the data.
1. What kinds of trees are most common? List some qualities of these trees
that you think would account for their popularity.
2. Are the same kinds of trees planted in the schoolyard as in the rest
of the community? If so, for what reason might this have been done?
3. What animals are most common? Which, if any, animals were found in only
one or two kinds of trees? Can your students suggest some theories explaining
their observations?
4. Do the same animals that live in or near the trees in the schoolyard
live in the rest of the community? If not, what could be the reason for
this?
5. Survey local residents. Why did they select the trees they planted in
their yard? What qualities of those trees did they find particularly attractive?
Extensions:
1. You might be able to find out where the oldest tree in your community
is located. Call the parks and recreation department of your area and ask
them if they know where it is. An article can then be written by the students
for your local newspaper about the tree, the history it has seen and interesting
facts about the species.
2. Your students could prepare information for the public about local trees
and their care. The information should include a list of trees that grow
well in the area and which are suited to particular settings. It could also
include information about tree pests and what to do about them and about
how to encourage development of particular kinds of tree communities. This
information is available from your local Cooperative Extension agent or
a local nursery.
3. If your school has a newspaper, write a series of articles each week
about a different kind of tree on the school grounds. Include interesting
facts about the tree and make sure you give information on how to locate
it on the school grounds. If you can find out when the tree was planted,
your article could cover the history of the area through the tree's lifetime.
4. If your students have identified all the trees on the school grounds,
they can label each tree, giving information about the kind of tree it is,
its uses, its normal habitat and other facts interesting to the class.
Lesson III - Planning the Ideal Community
(Grades 6-12, Duration: 1 hour, Activity - 5 class periods)
Materials:
Part A:
-a map of the area around your school (see Getting Ready)
-chart paper or overhead transparencies
-marking pens or overhead pens
Part B:
-large pieces of paper
-colored construction paper
-tape or glue
-marking pens
Skills:
-representing
-identifying
-restructuring
-synthesizing
-creating
Objectives: Students will:
-map the locations of services and resources in their community
-create a map of an "ideal" community that includes all the services
and resources people need.
Background:
A community includes all the people who live in a place. Different members
of a community exchange goods and services so that all people get what they
need to live there. A thriving human community includes residential areas;
commercial areas; industrial areas; schools; public services (police, fire
department, hospitals); transportation systems; utility systems; food distribution
systems; recreation areas; and cultural resources (libraries, churches,
theaters, museums). In this activity, students will explore the elements
that compose a human community. They will survey the area around their school,
looking for community systems that help them live there. Then they will
plan an ideal community that meets all the needs of its members.
Preparation:
Decide on the size of the area that students will survey. For example, in
urban areas, a two-block area around the school is fine. Obtain or draw
a simple map of the survey area. Make a copy for each student. (Or have
students copy a sketch from the chalkboard). Also, make an overhead transparency
of the map or an enlargement on chart paper.
Procedure: Part A - Community Living
1. Ask students what they think a community is. Ask pairs of students to
list 5 places or services they use in their community. Examples might include
roads, schools, hospitals, electricity, parks, libraries, police services,
or movie theaters. As students share their ideas, list the examples on an
overhead transparency or chart paper.
2. Look over the list, and ask students whether anything that people in
the community need to live there is missing. Help class members think of
services or resources by asking questions such as the following: "How
do people get the food they need? Where do they live? How do they get around?"
Add new ideas with public services, public utilities and cultural resources.
3. Divide the class into groups of 3 to 6 students. Distribute the maps
to each student. Explain that groups will survey the area around the school
to find the community resources and services they listed in Steps 1 and
2. Divide the list equally among all of the groups. On the back of their
map, members of each group should write down the items they will look for.
When students find one of the items on their list, they should record on
their map the name and location of the item.
4. Take students for a walk around the survey area, allowing time for students
to look for and record their findings. Alternatively, you may assign students
to survey the area on their way to or from school.
5. Help students compile their findings on the class map. Using that map
as a focal point, lead a discussion about students' findings by asking these
types of questions:
-What community services and resources did you find? What seemed to be missing?
-Does the community have a problem because those things are not present?
-Would you have found them if you had surveyed a larger area?
-Were there enough services and resources in the area that you surveyed?
-Does your survey represent what you would find in other communities?
-What about the area around your home? What might be different?
-What did you learn from your survey? Did anything surprise you?
-What would you like to see changed in the community?
Part B - Community Planning
1. Explain that students will have an opportunity to be community planners
and to design an ideal community that meets all the needs of its residents.
Ask students to brainstorm a list of the facilities, resources and services
that their ideal community will include.
2. Using the same groups as in Part A, allow students 2-4 periods to plan
and map their communities.
3. Ask groups to share their maps with the rest of the class and to describe
the features of their design.
4. Use these questions to lead a discussion about the maps and the planning
process:
-How did your group decide what features to include and where to place them?
-Give an example of how your group resolved a disagreement.
-Compare your ideal communities to actual communities. How are they: the
same? different?
-What would it be like to live in each of the ideal communities?
-What would it be like for a young child? For a store owner? For an animal?
-What did you learn from this activity?
Evaluation:
In examining students' maps, look for their understanding of the elements
necessary to sustain a thriving community. Consider how well students balanced
basic services and resources with social, cultural and recreational needs.
Did students incorporate natural resources in their maps?
Enrichment:
1. Invite a representative from an urban planning office or firm to visit
your class. Students can ask the planner about the process in which land-use
decisions are made, about the community's goals for the future or about
changes the community anticipates making as it grows.
2. Interview residents who have lived in the community for more than 25
years. Ask them how the community has changed and whether they think the
changes were for the better.
3. Use a computer program such as "SimCity" or "SimCity 2000"
to test the "ideal" communities designed in Part B. At the start
of the program set the speed to pause. Allow a group to build a community
with the funds available. Then allow the city to run for a set number of
years without additional construction. The programs simulation of population
growth, crime levels and tax revenues can be used to evaluate and rate each
design.
Lesson IV - Are There Any Clear Cut Answers
(Grades 6-12, Duration: 1-2 periods)
Materials:
-Westridge Forest map
-sets of role cards
Skills:
-classifying
-analyzing
-hypothesizing
-communicating
-valuing
-problem-solving
Objectives: By the end of these investigations, your students should be
able to:
-list 4 forest uses to be considered in developing a management plan for
a public forest;
-explain the relationship between the amount of ground cover in an area
and the amount of runoff;
-predict the effects of specific circumstances (forest fire, large clear
cut, human development, climate) on the stream flow in a watershed;
-list 5 benefits provided by trees;
-explain the difference between clear cutting and selective cutting and
when each is used:
-define a watershed
Background:
A topographical map is a special map that shows the shape and elevation
of the land as well as cultural features (cities, roads, buildings, bridges,
etc.). The most important feature used on a topographic map is the contour
line. A contour line can be straight or curved and connects points of the
same elevation or height on the map. The map key often tells you the elevation
difference between contour lines. On the Westridge Forest map included in
this activity each contour line represents a change in elevation of 20 feet
(about 6 meters). The set of concentric elevation lines or curves in the
lower right quadrant of the map represent the peak of "Elk Mountain".
Counting the number of contour lines from the peak of the mountain down
to the valley to the west, on the left side of the map, shows that "Elk
Mountain" has an elevation of more than 400 feet (123 meters).
Setting the Stage:
Familiarize your students with the major topographical features of the Westridge
Forest, using the map. A river flows through the forest from southwest to
northeast. The western slope of the river near the western border of the
forest is bounded by a steep cliff. The forest on the eastern side of the
river is hilly and covered with Douglas-fir and lodgepole pine. The western
side of the river gradually levels out from the steep cliff into a forested
flatland and a meadow. Black cottonwood and black willow trees grow along
the river. The western side of the river is primarily covered in Engelmann
spruce and aspen. Tell your students they will be developing a forest management
plan for this 10,000-acre forest.
Procedure:
1. Divide your class into groups of 4 and give each group member one of
the role cards. Each group should include a wildlife biologist, a forester,
a watershed manager and a recreation specialist.
2. Now give each group a copy of the forest map and the worksheet on the
last two pages of this lesson.
3. These instructions cover the information your students need to develop
their plans:
-Many different professionals, such as foresters, wildlife biologists, recreation
specialists and soil scientists work together to manage large forests. Each
of these people is responsible for developing a plan to manage the forest
as a recreation area, a wildlife habitat or a source of timber, depending
on his or her specialty. For example, a wildlife biologist is primarily
responsible for maintaining good habitat for wildlife in the forest. The
forester is responsible for developing a system to replace trees as they
are cut for timber and for designing a system of logging in the most efficient
and environmentally sound way.
Each student group is going to develop a management plan for this forest
which will allow recreation, logging, wildlife habitat, and a healthy watershed.
You each have a different role to support. You will help develop a management
plan for this forest based on what you, in your role, feel is important.
Use any method you want in order to develop your plan. You can draw it on
a large piece of paper or you could make a three-dimensional representation
of it showing the management procedures you will follow. But keep in mind
that you must consider future needs as well as present ones as you develop
your forest management plan.
Before beginning your plan, each group should work together as a group to
complete the work sheet. The questions on the worksheet are answered on
different role cards or the map, and each one of you will be able to answer
some of the questions for the group. This will help you keep in mind all
the considerations you must follow as you develop your plan.
4. Allow ample time for the groups to choose their own methods and to develop
their plans.
Evaluation:
When the plans are finished, display them in the classroom. Allow each group
to make a brief presentation answering these questions about its plan. The
presentation should also discuss the problems the group experienced in developing
a comprehensive plan.
1. What factors were considered when your management plan was developed?
2. What problems did you encounter in developing your plan?
3. What compromises were necessary as your plan was developed?
4. What plans did you make for the future? What will be your logging plan
in 10 years? In 20 years? How will this affect the forest's ability to meet
other needs in the future?
To demonstrate why land management plans need to be flexible, pose the following
question. How would a forest fire that burned over 600 acres in the southeastern
part of the forest affect the wildlife and timber production? Allow each
group time to consider the problem then discuss it as a class. Note: There
are no correct answers to these issues, only well reasoned positions.
Extension Projects:
1. In most suburban and urban areas, trees along streets and in parks are
"managed." Someone is responsible for their care. Your students
could inventory the forested parks or street trees in their community. This
community inventory could also include a study of the benefits provided
by the trees and parks, a map showing the locations of the parks and/or
the "street trees", and information about the trees. Your students
could contact the local park or conservation authority to find out more
about the maintenance of the trees and perhaps become involved in caring
for them, raising money to replace dead trees or starting their own tree
planting program. Some questions that they can ask are:
a. What department maintains trees along the street and in the community?
b. Do local citizens have a voice in where and what kinds of trees are planted?
c. How much money is spent on tree maintenance annually? What does that
money pay for?
d. How are trees chosen for parks and street sides?
e. What kinds of problems (disease, parasites, accidents, vandalism, weather)
do maintenance crews have with trees, and do they have standard plans for
dealing with them?
2. Chestnut blight, Dutch Elm disease, the Tussock moth, and the gypsy moth
are some of the more notorious diseases or pests that destroy trees. Interested
or concerned students may want to identify tree afflictions, their origins,
the trees and geographical areas they affect, remedies for them, and the
damage they do, both to the trees and to commerce.
Forest Manager Role Cards - cut apart for use in activity
Forester
It's up to me to make sure the forest continues to produce timber and meet other human needs. I must reforest at the same rate I harvest to assure a sustained yield. The Wildlife Biologist, the Watershed Manager, and the Recreation Specialist here at the forest all help me in making decisions.
It's my job to develop recreational facilities within the forest. I would like to develop a 25 ft. wide, 10-mile cross country ski trail and a 50-acre campground. My campground should be in a good stand of trees and have small clearings for the campsites.
It's my responsibility to make sure this forest provides suitable habitats for many different kinds of animals. Deer live on the eastern side of the river, but their numbers are decreasing. They go down to the river for water and they feed in meadow and shrub areas close to the river and in openings of the forest.
This national forest protects the watershed for the city of Cleveland Falls, 50 miles downstream. The vegetation in a forest keeps water from running off the land too quickly and causing erosion, which is a problem particularly when steep hillsides and areas along streams and rivers are logged. In this forest, we can never log along the very steep slope on the southwestern side of the forest.

Objectives: By the end of the investigations, students should be able to:
-define carrying capacity and explain the effects of different animal population
sizes on the habitat
-predict the effects of certain environmental changes on a wildlife population
Background:
This investigation is designed to help your students understand the interrelationships
of organisms within the environment and the complexity of managing resources.
There are no easy solutions. The best solution provides the greatest good
for the greatest number of people and wildlife while also considering the
importance of conserving our natural resources.
Setting the Stage:
Begin this investigation by introducing your students to a hypothetical
problem of managing a large herd of elk in a national park. The elk are
protected in the park and ten to be somewhat less shy of people and more
commonly seen than they generally are in the wild. They attract visitors
to the park, but the size of the herd s a problem. The park presently has
a population of about 1,800 elk but it can support only 800 elk on a year
round basis without harming the habitat. The elk eat a variety of foods
including the leaves and twigs of aspen. Over browsing is destroying the
aspen in the park, Other tree species are being affected, although to a
lesser extent. Some biology researchers feel the elk population must be
reduced or the aspen in the park will be completely destroyed in ten years.
This would adversely affect other animals, such as beaver and deer, that
also depend on aspen for food. In summer, the elk can feed on extensive
range high in the alpine tundra in the park. In winter, however, snow prevents
the elk from feeding on this range and there are few other areas in the
park where abundant food is available to them. The elk are overfeeding on
the available winter range and damaging the vegetation. The herd's seasonal
movement to feeding areas outside the park is restricted by the human population
living in nearby towns and by hunters in the fall. Because hunting is not
allowed in national parks, the elk tend to stay within the park boundaries
where they are protected from people who hunt in areas surrounding the park.
Elk compete with other wildlife for available habitat in the park. The park
supports mule deer, bighorn sheep and many small animals, such as beaver,
gopher and ptarmigan. A few cougars live in the park, but the absence of
other predators of the elk, such as wolves and grizzlies, contributes to
the overpopulation problem.
Procedure:
1. Divide your class into small groups. Each group must work together to
find a solution to the problem of overpopulation of elk in the national
park.
2. Allow your students twenty minutes to come up with as many different
ways to solve the problem as they can. Try not to limit their thinking in
any way. These questions may help them in the process:
a. What can we do to decrease the number of elk in the park?
b. What ways to decrease the population involve the least obvious human
intervention?
3. After twenty minutes, write all of their solutions to the problem on
the board. Use the following questions to discuss each solution:
a. Which plans do you think will not work? Why?
b. What additional information do you need to decide whether each is possible
or not possible? (Make a list of this information.)
c. Which plan seems to be the most effective way of dealing with the problem?
Why?
4. Now, give a set of the role cards on the next page to each group. Each
group should analyze the roles and answer these questions:
a. Which solutions suggested in the role cards are similar to those suggested
by the group?
b. Which statements made by each person are facts and which are opinions?
(Make them aware that sometimes opinions begin with phrases such as "Some
people think", "I think", and "I feel".)
c. Which of the solutions suggested in the role cards appears to be the
best?
d. Can you combine your solution and solutions suggested on the role cards
to form an even better solution? What is it?
5. Once each group has analyzed the roles and come up with another solution
or confirmed the group's first solution, have each group present its solution
to the other members of the class. Discuss each solution and allow other
class members to ask questions.
6. The class should now vote to decide which solution appears to be the
best. Their choice may be the original solution, one of the solutions arrived
at after reviewing role cards or a combination of two or more. Make sure
the class as a whole is given the option of deciding to reject all or to
combine parts of several solutions into one choice.
Evaluation: These questions may be used to summarize the investigation:
1. Are there any contradictions in the individual statements made on the
role cards?
2. Look at each statement. Are there enough facts in each one to make an
intelligent assessment? What other facts do you need to make an intelligent
assessment? What information on the role cards do students feel they needed
when they suggested their first solutions?
3. How, if at all, are the statements on the role cards biased?
4. Are there some choices that appear effective as a short term solution,
but present some long term problems? What are these long-term problems?
As a follow-up, you may want to invite a wildlife manager from your local
area to your class to discuss the problem as it relates to your locality.
A similar wildlife management problem may exist in a local park or wildlife
refuge.
Extension:
This investigation is based on actual problems that Yellow-stone and Rocky
Mountain National Parks have had. Students may want to research National
Park Service park management policy for these situations and compare official
policies to the decisions that the class made in their votes.
Role Cards: These should be cut apart for use in the activity
President of "Elks Alive"
"We think the only solution is to relocate the extra elk to other habitats
around the country. Elk once occupied areas where they are not now present.
We could raise funds to carry on the relocation this year. It will cost
us $200 per elk, but we could provide the funds with which to live-trap
the elk and move them elsewhere. We're not sure that we could pay for relocation
year after year, though. A hunting season should not be started in the park.
Overpopulation of animals sometimes results from certain management practices,
such as planting feed for animals or setting out hay and other food for
them. If we start a hunting season in the park, that management style might
continue and force the park to have a hunting season every year. This might
interfere with the enjoyment of visitors to the park because the elk in
the park will be more shy of people. Our national parks are set up to be
places where people can go to see wildlife and we think those opportunities
should be preserved at all costs."
Owner of the Local Photography Shop
"I depend on tourist trade here in my business and elk are a big attraction
in this park. If we don't get visitors here to see the elk, we won't be
able to make a living but the hunters have a tendency to kill all the "pet"
elk that pose for pictures. This gives hunters a bad name and causes some
of us a lot of personal grief. Starting a hunting season in the park would
also set a bad precedent. What if we start doing that in other parks as
well? There should be some places left for people who want to see animals.
Hunters already have plenty of places to hunt."
Wildlife Manager
"There are many different ways to solve this problem and we have to
find the best way. We could have a regulated hunting season. We could have
park rangers live-trap or sedate the elk and move them some place else.
Although we could try to reintroduce the elk's natural predators, such as
wolves, cougars and grizzly bears, research has shown that with few exceptions,
predators are unable to regulate the large numbers of prey in parks. Another
problem is that the bears and the wolves could create a threat to people
and could be animals that visitors might not like to have in the park. However,
reintroducing predators along with an elk removal program might help control
the elk and reestablish a natural predator-prey relationship."
Park Superintendent
"We can't reintroduce grizzly bears to the park because they would
serve as a threat to people. While the park can support some wolves, it
is not big enough to support a wolf population that's large enough to control
the elk population. Besides that, the wolves might prey on other species
such as bighorn sheep, deer and beaver which are also protected in the park.
Live-trapping was tried in other areas, but all the other elk habitat is
also full. We really don't have any other place to put them. Besides, live-trapping
is too expensive. We just don't have enough money."
Wildlife Biologist
"We must remove at least 1,000 of the elk from the park or the aspen
and other vegetation they eat will be destroyed, not only on the winter
range, but if the herd continues to grow, on the summer range, as well.
Other kinds of wildlife in the park that eat aspen will also be affected.
Beavers need aspen too. Without aspen, the beaver population will disappear
and that's just one of the species the elk are affecting. There are several
different ways to solve the problem, but we have to find the one that works
best for this park, We could try to acquire other range areas for winter
feeding. Hunting is recommended in many areas by wildlife managers, and
it is an effective means of helping to control overpopulation. Live-trapping
is recommended in other areas. I think we should trap the elk and then kill
them. The meat can be given to charity and trappings will not cause the
other elk to become afraid of human beings. National parks were set up to
be places where people can go to see wildlife and a hunting season in this
case may not be the best solution since it might make the elk less tolerant
of people."
Local Farmer
"We must do something about the elk. They are eating the hay I harvest
for my livestock. I don't like the idea of introducing predators-mountain
lions, wolves and grizzly bears-into the area. If you bring predators into
this areas, they're going to get to my livestock. That's going to hurt me
economically and it may even pose a threat to my family. I don't want these
dangerous animals in the area and I certainly don't want them near my livestock
and family. Why not just have an open hunting season?"
Park Ranger
"They tried a hunting season in Grand Teton National Park and it didn't
work because not enough hunters would participate in a hunt that was so
tightly regulated. Also, once elk are shot in the park, the herd is less
tolerant of humans and not as readily observed by park visitors. In this
way, hunting would interfere with the enjoyment of park visitors who want
to see the elk. Why not allow the park rangers to selectively trap, move,
and kill the extra elk in the park? The wildlife biologists and managers
could recommend which elk we should shoot and the meat could be given to
charity or schools."
President of "Hunters for Conservation"
"My organization is willing to help participate in a hunt in the park
to reduce the number of elk. The people within our organization are extremely
responsible and concerned about conservation of all kinds of animals. We
can work with the park authorities and state fish and wildlife representatives
to set up the best kind of hunting situation, and I think we should open
the park to hunters even though hunting is not normally allowed in our national
parks. This would not only cut down on the number of elk in the park, but
the hunters coming in to participate would spend more money on the local
economy."
