The Washington White-tailed Deer Project (WWP) that began in 2012 is investigating northeast Washington white-tailed deer seasonal movement patterns and home range, survival and productivity, and habitat quality, use, and selection.
The survival and productivity research includes a study of white-tailed deer body condition because it affects the ability of does to successfully reproduce and yearlings to survive. Body condition is strongly related to body fat levels.
WDFW is currently estimating seasonal fat levels of yearling and older whitetail does in several northeast Game Management Units (GMUs) by measuring fat deposits around the heart and kidneys of hunter-killed deer. Hunters can help by allowing WDFW biologists to examine the heart and kidneys of harvested antlerless deer.
Detailed information about how to collect and submit samples (also including a tooth to age the animal, a liver tissue sample for a mineral level analysis, and the reproductive tract of adult female deer) is provided here:
