It is interesting data, but I'm not sure how accurately it reflects deer populations and the impact upon those populations by coyotes. Without knowing how many different hunters in different settings provided the information, and how observant those reporters are with their observations, it would be hard to say that coyotes are impacting deer numbers.
I went back to deer harvest statistics for the 2008 archery season and found numbers that appear to be opposite of what the deer sightings indicate.
Harrison - 431 deer killed during archery season 2008/2009.
Worth - 171
Grundy - 216
Gentry - 253
Daviess - 360
Mercer - 397
So while those hunters reporting deer/coyote observations are reporting fewer deer and more coyote observations in Harrison County, Harrison County hunters are killing more deer.
