My colleagues and I did a lot of plant mapping from highways at about 55 mph. Yes, in some areas you really can ID Poa secunda and Juncus balticus at those speeds.

That reminds me of this field guide to roadkill from a while ago:

Thanks for sharing this. It’s a useful concept, and expanding it to other regions would be really helpful.

I’ve occasionally done so-called “windshield surveys” of habitat when time was short and I and my colleagues had important places to be. This guide could be useful for those surveys, although generally we do them at lower speeds (too fast for a decent photo, but slow enough you could at least make out the shape of a leaf).

Yahoo! I finally figured out what all those purple things are!

I would be curious to know whether the photos were really all taken from a car window at 70 mph – the Hypericum flowers seem rather large for a carside view, as do the Grindelia.
Unfortunately there is no information about the photo sources or methodology (Type of camera used? Focal length? Shutter speed?)
I suspect the photos are the product of photoshop or something similar.
