DESCRIBE THE HABITAT REQUIREMENTS AND OTHER

FACTORS THAT AFFECT WILDLIFE SPECIES

NATURAL RESOURCE IFISHERY AND WILDLIFE MANAGEMENT

OBJECTIVE 5.03

HABITAT• THE BASIC REQUIREMENTS OF FOOD, COVER, WATER, HOME RANGE AND TERRITORY

ARE ALL PART OF AN ANIMAL’S HABITAT.

CLASSIFICATION OF ANIMALS BY FOOD VARIETY

COVER• A PLACE FOR PROTECTION FROM

WEATHER• A PLACE FOR PROTECTION FROM

PREDATORS

WATER• IMPORTANT REQUIREMENT OF WILDLIFE

• MOST ANIMALS BODIES ARE 60-80% WATER

• IMPORTANCE: BLOOD COMPOSITION, TEMPERATURE REGULATION, AND NUTRIENT TRANSPORT

• SOME ANIMALS GET MOST OF THEIR WATER FROM FOODS THEY EAT

HOME RANGE AND TERRITORY• HOME RANGE: THE AREA OVER WHICH

GAME TRAVELS, WHICH COULD BE FROM ONE ACRE TO HUNDREDS OF SQUARE MILES

• TERRITORY: THE AREA AN ANIMAL WILL DEFEND, OFTEN TO THE DEATH

GAME MANAGEMENT PROCEDURES• GAME REFUGES ARE LANDS SET ASIDE FOR PROTECTION OF WILDLIFE SPECIES

• HABITAT DEVELOPMENT AND IMPROVEMENT OCCURS WHEN HABITAT IS DEVELOPED AND MANAGED FOR MAXIMUM BENEFIT TO WILDLIFE

• FENCEROW PLANTINGS

• WOODLAND MANAGEMENT-NOT USING WOODLAND FOR GRAZING WILL INCREASE GAME POPULATION

COORDINATION WITH OTHER RESOURCES• MANAGING THE WILDLIFE IN COORDINATION OR HARMONY WITH OTHER RESOURCES;

EXAMPLE: FARMER MANAGING THE SOIL PROPERLY TO GROW CROPS, LEAVING SOME FOR WILDLIFE TO EAT

HUNTING REGULATIONS• HUNTING MUST BE MANAGED TO CONTROL WILDLIFE POPULATION

• SOME PROCEDURES ARE BAG LIMITS, HUNTING SEASONS AND CLOSED SEASONS

• TOO MUCH WILDLIFE (OVERPOPULATION) CAN CAUSE TOO MUCH COMPETITION FOR HABITAT

• TOO MUCH HARVESTING CAN CAUSE UNDER-POPULATION.

PREDATOR CONTROL

• INVOLVES CONTROLLING PREDATORS OF THE GAME, RATHER THAN GAME

• PREDATORS CAN KEEP GAME HEALTHIER

• PREDATORS MAINTAIN AN IMPROVED GAME POPULATION BY REMOVING WEAK

ARTIFICIAL STOCKING• INVOLVES BRINGING ANIMALS INTO AN AREA

• CAN INVOLVE BRINGING ANIMALS NATURAL TO THE AREA OR INTRODUCING A NEW SPECIES TO AN AREA—CALLED “INTRODUCTION OF EXOTICS”

NEED TO CONSIDER

•POPULATION DENSITY—REFERS TO NUMBER OF GAME ANIMALS IN A DEFINED AREA

NEED TO CONSIDER• CARRYING CAPACITY—THE AMOUNT OF GAME AN AREA IS ABLE TO SUSTAIN

LEGISLATION AND GAME MANAGEMENT• GENERALLY MANAGED BY EACH STATE

Major legislation governing wildlife

• LACEY ACT OF 1900: FIRST MAJOR LAW AFFECTING WILDLIFE. MADE FEDERAL

OFFENSE TO TRANSPORT ILLEGALLY TAKEN WILDLIFE ACROSS STATE LINES. (AMENDED

IN 2008 TO INCLUDE PLANTS)

MAJOR LEGISLATION GOVERNING WILDLIFEMIGRATORY BIRD ACT OF 1929—PROVIDED REFUGES FOR MIGRATORY BIRDS

MAJOR LEGISLATION GOVERNING WILDLIFE• ENDANGERED SPECIES ACT OF 1966-GAVE THE AUTHORITY OF PROTECTING RARE

AND ENDANGERED SPECIES TO THE FISH AND WILDLIFE SERVICE.

EXTINCTION OR ENDANGERMENT• ACTIONS THAT LED TO WILDLIFE POPULATION PROBLEMS

• TAKING ANIMALS FASTER THAN THEY CAN REPRODUCE---

BISON

EXTINCTION OR ENDANGERMENT• KILLING ANIMALS BECAUSE THEY APPEARED HOSTILE

SEEN AS A THREAT TO PEOPLE

EXTINCTION OR ENDANGERMENT• SEEN AS A THREAT TO DOMESTIC ANIMALS

EXAMPLE: THE RED-TAILED HAWK DID NOT EAT MANY DOMESTIC ANIMALS ANYWAY
