Creating a Habitat
Laying the Groundwork
Author: Eve Pranis
A creature's habitat is a place where individuals of that species or type can usually be found. It contains all the components the organism needs to survive.
At the most basic level, all wildlife require food, water, shelter from predators and the elements, and safe places to raise their young. Consider asking your students to brainstorm and create a list of things humans need to survive. Then try creating a list for other animals and one for plants.
How do the lists compare?If you want to invite more wildlife into your school grounds, you should first discover who's already in the neighborhood and what types of features and conditions exist, then decide who you'd like to attract and learn about the habitat requirements of your intended guests.
Lay the groundwork. Invite students to explore the schoolyard and keep a record of their observations.
What types of life forms can you find? What part of the habitat is each found in (under rocks, on plant leaves, in water)? Do some organisms seem to prefer certain conditions (sun, shade, moist areas)? How are they interacting with other living and nonliving parts of their environment? Do animals seem to be using certain types of plants for food? Shelter? You may also want to explore nearby lots, parks, and so on, to get an idea of the wildlife in the area that might be enticed to the schoolyard. Invite students to compare the amount of wildlife in an area like a lawn, with few plant species, to what's in a meadow or even a weedy lot. (They should discover that as the diversity of plants increases so does the amount and diversity of wildlife.)
Assess site conditions. Challenge students to evaluate the characteristics of your own site.
Which habitat elements already exist? A water source? Key plants? What
are the sun and shade patterns? Students can use a grid system to create a scaled map of the area that they can use as a template for planning.
Develop a plan. Once you have a sense of what conditions you have and the types of wildlife that might be in your area, devise your own plan. Have students research the needs of wildlife they hope to attract, then list the plants and other features they'll need to include. Remind them to consider a creature's entire life cycle; butterflies, for instance, have different food requirements as caterpillars than as adults.
Which habitat elements will you need to modify or introduce? Then consider the physical changes you might make (e.g., bird-feeding stations and brush piles) and types of plantings (butterfly garden or prairie restoration). How will you enhance your area for human visitors (building an interpretive trail or making a viewing guide to your wildlife habitat)?In general, the greater variety of plant types you have (trees, shrubs, perennials, annuals, and so on), the more wildlife you'll attract. Native plants are better adapted to local conditions and to wildlife needs. You'll also tend to find more wildlife in transitional areas where two types of habitats meet, such as the edge of a woods and a meadow. Think about ways to provide water for wildlife. This can take the form of mud puddles, bird baths, or ponds. Never use pesticides or herbicides in a garden or site meant to attract, feed, and shelter wildlife.
Additional ExplorationHere are more suggestions for sparking learning and deepening students' understanding of the world around them.
Invite students to create an indoor habitat exhibit.
Have them use drawings and magazine and seed catalog clippings to
create a display depicting a habitat for butterflies, birds, or other
animals.
-
Challenge students to think small and discover micro-habitats
within a schoolyard wildlife habitat: a rotting log, mud puddle, or
anthill, for instance. Ask, What plants and animals can you find?
What habitat components are there? Is the temperature different than
in the surrounding area?
-
Have students find out as much as possible about the
creatures they find in their garden or natural habitat (e.g., where
they live, what conditions they prefer, what they eat, how they protect
themselves). Find out what factors influence the loss of habitats
for a given species.
-
Once students have learned to identify different types
of butterflies or birds, brainstorm why each may have acquired its
name (e.g. tiger swallowtail). Invent names for newly spotted birds
or butterflies based on observable characteristics.
-
Invite students to investigate which flowers butterflies
seem to prefer. After carefully observing and comparing favorite butterfly
flowers to others in your garden or wildlife meadow -- noticing shapes,
nectar location, color, and so on -- have students infer what are
the features of a good butterfly nectar plant. Ask, Do other factors,
such as wind protection, seem to affect feeding preferences?
-
Create an electronic database of the wildlife in your
habitat, including common and Latin names, locations, habitats, and
so on.
-
Explore winter survival strategies (e.g., migration
or hibernation) of animals in your schoolyard habitat. Ask, What
challenges does each strategy present? What adaptations allow the
animal to survive?
-
Invite students to create "advertisements" to attract
butterflies, birds, and other wildlife to your habitat area. Be sure
to highlight features that would compel particular animals to visit
your site. (You might also use this activity to assess students' understanding
of physical and biological elements of habitats.)
-
Create a field guide to your garden or wildlife habitat
based on students' observations and research. Include sketches and
names of inhabitants, where they would be found, food preferences,
seasonal habits, and so on.
-
Have students write stories from the standpoint of
an animal in their wildlife habitat. Be sure they include references
to habitat components that help the animal meet its needs.
