Historical Background in Georgia

1880– Limited to forested regions

1900-1930– Large scale logging resulting in significant habitat destruction– Unregulated hunting or trapping

Bears in Georgia

1930’s– Bear season closed by act of legislature

1930-1970– Questionable protection – Limited habitat

1969– Georgia Game and Fish Commission as well as hunting

community realized value/importance as game species 1976

– Tri-State Bear Study launched to investigate bears in SE

Bear Reproduction

Breeding Season– July

Males may breed at 1.5 years of age

Females breed from 3.5 to 4.5 years of age

Page 9: BLACK BEARS  ( Ursus americanus )

Spring Time is Bear Time!

Emerge from dens. Desperate search for

food to recover lost body weight during winter months.

One-year old bears begin search for their own territory.

Nuisance Bear Issues

Common Nuisance Bear Situations– Wandering Bear

1-2 year old male Establishing territory

– Habituated Bear Usually food related May cause property damage

– Agriculture Bear– Just There Bear

Page 20: BLACK BEARS  ( Ursus americanus )

Common Nuisance Situations

Residential Bears– BIRD SEED– GARBAGE– PET FOOD– Compost Piles– Fruit Trees and Shrubs– BBQ Grills

DO NOT FEED BEARS!DO NOT FEED BEARS!
