This is a significant improvement over the sixth edition.
They're more consistent about including range maps (but still exclude them for introduced species, which I find a little irksome), and species accounts are greatly expanded in many cases (including some extinct species-the discussion over just how common grizzly bears ever where in state is interesting). There's also updates to several range maps (elk, cougar, black bear , porcupine, etc) as populations have changed since 2004.
The writing also seems more engaging, although that's hard to quantify. I also noticed fewer copy editing flubs (in my review for the sixth edition I noted that they'd apparently had put the size in lbs for cougars but noted labeled in kilograms--cougars don't get 200 *kilos*).
