In Hawaii...they have a program called Green Harvest. The choppers fly around in the mountain sides looking for plants @ night. I has been reported they do give off a signature.
Once, located...it will be gone.
If they fly close enough to the land that they can use the Infrared emitter on the helicopter to actually illuminate the foliage, they can process the image and view it in that way, yes, but they would have to fly close enough that using that technique for searching large areas would not be effective. But it IS totally possible for them to fly/scan mountainsides and valleys that are remote but accessible (they know from experience where the hotspots are and where is best to look first). And Hawaii is small enough that they prob could cover alot of the "hotspots" that way. Not in Texas or Montana or even rural California. But not for heat. for the reflection of specific light waves off the plant surfaces (yes even at night)
