This is another great idea! This might be a separate instant answer than the climbing one we were discussing above, but it is relevant on this page since its close to the same idea. I think the first thing needed is to find a good source with an api. The more information from 1 source, the better. I checked out your first link, and there seemed to be a good api for all sorts or recreation at http://www.usda.gov/wps/portal/usda/usda... and it seems fairly extensive. Though it should be looked into a little more.
