The need for food and water is obvious.
Cover is not only needed as shelter from the elements and predators,
but it’s also necessary to protect animals while they are feeding, breeding,
roosting, nesting, and traveling. Cover can range from thick weeds and
brush to a few rocks piled together.
Space is necessary to avoid over-competition for food. Some animals
also need a certain amount of territorial space for mating and nesting.
When crowded, some species may develop stress-related diseases.
Arrangement refers to the placement of food, water, cover, and space in a
habitat. The ideal arrangement allows animals to meet all of their needs in a
small area so that they minimize the energy they use traveling from food to
cover to water.
For example, quail will spend much of their time where shrub and grassland
areas converge. This is called edge effect. Edge effects
can be in the form of topographical or vegetation edge such as the saddle
of a mountain range. Most animals can be found where food and cover meet,
particularly near a water source. River bottoms are ideal, offering many
animals all their habitat needs along one corridor. |
