[QUOTE="BSK, post: 5021681, member: 17"] Habitat diversity is a key factor in deer usage of an area. Years ago, I used to give a lecture at deer hunting/management symposiums on how critical habitat diversity was for hunting success. I'll have to go back and see if I can find some of the graphics from that talk. As some background, I got involved in deer management because of my background working with the U.S. Census Bureau on Geographic Information Systems (GIS) and "spatial statistics." GIS is a digital mapping system that has data linked to the features in the map. Spatial statistics is statistical analysis based on how geographically related the data is (data collected from locations close together will be more related than data collected from locations farther apart). Spatial statistics has a lot of relevance in deer management. In essence, statistical analysis of data from your neighbor's property has far more relevance to your property than data collected from two counties away. Spatial statistics provides a numerical means of accounting for that relevance. Basically, it provides a way of giving more statistical "weight" to data collected closer geographically than data collected farther away. As most know, I require anyone hunting my property to collect extremely detailed observation data while hunting. I even have every stand location used for more than 20 years marked with highly accurate GPS (sub-meter accuracy). I've also had a GIS map of the property's habitat for every year since the late 1990s. Because I can link a hunter's observation data to a geographic location, I can spatially analyze that data against just about any factor that is also geographic. On a lark, I looked at every stand location and measured the habitat diversity in that location for that year (counted the number of different habitat types within 100-yard radius circle of the stand), and then compared that to the hunter's observations.

In essence, hunters' deer observations rates were almost perfectly associated with how diverse the habitat was around their stands. The higher the habitat diversity, the more deer they saw while hunting. However, there was one caveat to that. In bumper acorn years, sighting rates could be very high from stands in non-diverse locations that were all oaks. But outside of that one caveat, and especially in poorer acorn production years, habitat diverse was THE key to seeing the most deer from a particular stand location. [/QUOTE]
