According to http://www.seattlepi.com/news/science/a ... 416031.php
About 30 percent of the collared fawns in the northern [WI] forest and 15 percent in the farmlands have died. Adults have fared better, with 6 percent loses in the north and 2 percent losses in the farmlands. Causes of death include predation, car crashes and starvation.
I know this probably only applies to about a half dozen states, but I thought I would post to at least provide a new topic. Been a bit slow here lately.
