The IR imagery commonly available is usually not taken at a large enough scale (better pixel resolution) to identify tree species. That kind of IR photography is usually done for smaller custom projects such as for a particular forestry company and so forth. Typically your entire state IR imagery will not be helpful, nor will it be the raw IR imagery.

I will be testing IR photography using quadrocopters (UAV's). I will let you know what we end up with. Maybe we could help you with high resolution IR imagery very soon!

Has anybody had any success with this since originally posted? I was thinking about trying to do the same to locate maple bushes and then contact land owners in the area I'm looking. Some of the land holdings in the area are not road side, so drive-by's won't always tell me. Anybody good at locating maple stands by using google earth? I'm not great at it, but would describe the maple foliage as looking like a head of broccoli as compared to others woods.

The last 2 times Google earth updated the imagery in my area was just at the time in the spring when the maples were that chartreuse? green and most other hardwoods were still looking dormant. You can pick out a tree or a bush a mile away. You could look at Bing maps also.

I'd first zero-in on areas with slope if your plan is to use tubing. THEN, discern species of trees.

Not to get too technical, but IR imagery is really only good for decerning between veg and non-veg or measuring relative plant health, in this particular situation. To differentiate between species of trees hyperspecral imagery is needed, which even with the high tech satellites we have today, do not give enough resolution to make a decent comparison between species or trees
