Population Dynamics And Ecology Of White Tailed Deer In Illinois PDF Download

Excerpt from Ecology of White-Tailed Deer in Illinois: Final Report W-63-R(si)31; July 1, 1986 Through June 30, 1989 Annual hunter harvests are often the deer manager's primary source of information regarding the herd, and there are a variety of techniques and methodologies for the analysis of harvest data. These methods, which range from Sophisticated mathematical treatments to simple intuitive interpretation, vary widely with respect to input requirements, output produced, and underlying assumptions. There is not general agreement as to which techniques are most applicable in given situations. In fact, there is a marked tendency for individual agencies to adopt and utilize a particular method (or variation thereof) to the exclusion of all others. Often, the accuracy and/or precision of these can only be assumed in the absence of verification with known data. Downing recognized this problem and suggested that: we need to look at a herd where we know what's happening in order to find out what data are most useful [for detecting what has happened or predicting what will In the Opinion of Davis and Winstead The failure of wildlife investigators to check population estimators against a known population is a deplorable situation.
