Forage Relationships between Two Deer Species in Big Bend National Park, Texas
Krausman PR. 1978. Forage Relationships between Two Deer Species in Big Bend National Park, Texas. The Journal of Wildlife Management. 42(1):101-107
Stomach contents of 25 Carmen Mountains white-tailed deer (Odocoileus virginianus carminis) and 29 desert mule deer ( Odocoileus hemionus crooki) were collected on allopatric and sympatric ranges between June 1972 and April 1974 in Big Bend National Park, Texas. Browse constituted 35 percent, succulents 28 percent, forbs 14 percent, and grasses 4 percent of the white-tails diet. Mule deer ate more succulents than browse (38 vs. 27%) while forbs made up 19 percent of the diet and grasses 3 percent. Significant differences (P<0.05) existed in the diets of both species between allopatric and sympatric range and between diets on sympatric range. Factors other than forage were responsible for habitat separation of Big Bend's 2 deer species
