[PCA] Seeking US statistics!! Please help.

[Addsum-Tony Frates]

Thank you for these links.

The maps and discussion in the last one are particularly alarming, i.e.:

http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0023002

Overlay those maps with FWS Region 6.   Yet that region has almost  
completely stopped listing species under the Endangered Species Act in  
the past five+ years.   Why?!

This also shows why it is very difficult for anything to "recover"  
under the ESA when these ecosystems have been so tremendously altered.  
   Lack of recovery in many of these cases would not be due to the  
ineffectiveness of the Act as often claimed by pundits.

The invasive weed ("uncharacteristic" vegetation! - I sort of like  
that terminology in one sense, but it also certainly greatly takes the  
punch out of the problem in another) problems of the Great Basin  
outlined in that document are also very disturbing.
