More deer info than you may want--
I found a cool website, www.deer-departed.com, and it has a lot of information about "managing" deer populations, deer tick problems, and links to other resources. I got onto it because I'm trying to design a larger garden area and keep out the few deer we see in our yard and wetlands and yet retain our nice view, not have to look through a lot of fencing.
Within that website was a link to a map showing deer (whitetail) density everywhere in the US and one can zoom in and count the number of sightings. Wow, I hadn't realized how many deer there are in RI, and where. And in CT. And in MA. And....
Here is a link that might be useful: Deer Density Map
