Wildlife Habitat

Objective: Describe the basic requirements for fish and wildlife species and explain methods to improve habitat for fish and wildlife.

Habitat

Each species of wildlife requires a specific environment or habitat in which to live.

Forest and farm owners must be aware of those parts of the environment that wildlife need to survive and reproduce in order to properly manage land for wildlife.

Habitat

Habitat

Wildlife have specific requirements including Food, Cover, Water and Space.

These components must be arranged in an accessible fashion.

These four components must be present in sufficient quantity and quality in the species home range.

Habitat

Whitetail deer require 640 acres with a mixture of trees, plants and shrubs for food and cover, and a source of water.

Food

Food is an obvious components for wildlife habitat.

Animals with enough food and proper nutrition are larger and healthier.

Well nourished wildlife have higher reproductive rates, produce healthier offspring, are more disease resistant, and better able to escape predators.

Food

On the other hand animals without food have low reproductive rates and are highly susceptible to disease.

If disease depletes the population of small mammals predators may starve

Food Preferences

Deer and other herbivores have feeding patterns.

These patterns are called Food Preferences. Wildlife preferences can be put in four

categories.

Four Food Preference Categories Preferred- animals first choice, but not always

available for consumption Staple- foods eaten regularly that meet the

animals nutritional needs Emergency- meet animals short term needs,

eaten when staple foods are absent Stuffers- low nutrition, only eaten because

there is no other available food

Foods

Cover

Cover is a habitat component that provides the protection necessary for the animals survival and reproduction.

It provides shelter from bad weather and escape or screen while they feed, rest, and care for their young.

Cover

Cover is very important and relates to the functional needs of the animal.

Quail need about 40% forest, 50% cropland/pasture, and 10% brushy thicket.

Quail numbers have dropped in the southeast due to changes in the availability of cover.

One potential cause is large scale prescribed burning.

Cover

Prescribed burning clears out all the underbrush in the forest.

Cover

Patch burning is an alternative in which small patches are burned off instead of the whole forest

Cover

Some animals can use any type of cover, like opossums. They can live in cities, dumps, or farmland.

Other animals are more selective, however many of these can benefit from the same cover.

Rabbits, birds, and ground nesting wildlife will all benefit from cover established for quail.

Types of Brush Piles

There are many different types of brush piles

Could be logs, brush, rocks, junk, fallen trees, or a combination of these.

Water

Animals need water for digestion, metabolism, and cooling off.

Around 80% of an animal’s body is water. It is clear that water is very important.

In Alabama springs creeks, rivers, and farm ponds generally provide enough water.

Some animals get their water from lush vegetation which has a high water content.

Also small mammals get water from morning dew.

Water Sources

Space

Each species requires a certain amount of space. The space in which an animal lives is often called it’s home range.

There are many factors that determine how much space a wildlife species needs.

Determining Factors for Space Body Size- bigger animals require more

space Dietary Practices- Carnivores require more

space than herbivores Carrying Capacity- the amount of wildlife the

land will support Mobility- some animals travel long distances Territorial Behavior- some animals will share

territory, others will not

Territorial Behavior and Mobility

Arrangement of Habitat components Interspersion- mixing of forest, pasture, and

cropland. Creates Horizontal Habitat Diversity.

Vertical Layering- different layers at which plants grow. Creates Vertical Habitat Diversity.

Edge- a boundary at which two different plant communities meet. Like forest and pasture.

Ecotone- the mixture or transition of the two habitats

Edge Adapted Species

Edges are great wildlife habitat, many species prefer these areas.

These species include rabbits, quail, robins and the common flicker.

Edge Adapted Species

Headquarters

Also called coverts, headquarters are places where three or more habitats or vegetation types meet.

Like edges, headquarters are attractive to wildlife because they provide multiple habitat components in a small area.

Improving Habitat

First evaluate the existing conditions. Does your farm or forest have cover, food,

water, and space? Are there any edges and ecotones? Are there vertical and horizontal layers in the

forest? Are there thickets and brush piles for rabbits

and quail?

Improving Habitat

After your evaluation, make improvements to the areas which need work.

For example you might plant a ryegrass field for deer.

Improving Habitat

Old fence rows make good cover.

If there are no fence rows you could make a brush pile.

Improving Habitat

If water is a need you could plant lush vegetation and improve an old pond or build a pond.
