[QUOTE="Dr. K, post: 5212860, member: 20754"] I'm relatively new to the forum, but I have enjoyed the posts a lot. In response to Spurhunter's question about how many, I wanted to follow up because I have the information. TWRA followed the winter (post-season) population density for a number of years, including before and after the flood. When I say winter, the population density was estimated each winter sometime in either late December, January or February. So when you look at these numbers, just realize they are a snap-shot in time and do not reflect anything about movements to and from the island across the year (that's another interesting topic). You'll notice that 2010 was not represented, as no data were collected. The population density in the winter of 2011 was just before the flood in late April/early May of that year. The next year the population density declined by about 37%. If you visited the site after the flood, you will know how truly amazing the change was...sand everywhere and several feet deep in many places. In the estimate of the year that followed, the population density rebounded as was expected but declined once again. No more population surveys were conducted, to the best of my knowledge, after 2014. Given the comments, it would be very interesting to see how the population density compares this winter. Year Deer/SqMi 2008 70.7 2009 86.3 2011 73.2 2012 46.1 2013 66.6 2014 41.2 [/QUOTE]
