[RWG] New map of roadside weeds & natives from Jackpot to Wells, Nevada

[Craig Dremann]

Dear All,

I posted a new map at the bottom of my Megatransect web page, showing
mile-by-mile what the ecological conditions were along 68 miles of US
highway 93, from Jackpot to Wells Nevada in 1997, at 
http://www.ecoseeds.com/megatransect.html.

The map shows the locations of the cheatgrass, plus where the exotic
crested wheatgrass has been sown by the DOT--two of the major roadside
exotic plants of Nevada. 

The maps also shows where the native grasses were present, and there's a
detailed breakdown of the map's data on the web page.  

For example, in 1997 there was a pristine Great Basin Wild Rye prairie,
eighteen miles north of the town of Wells.  

Also there were 16 miles of Indian Ricegrass along that stretch of US
93, but unfortunately this formerly common native grass was extinct in
1997 outside of the roadside, making the highway right-of-way an
extemely important refugia for that species. 

Sincerely,  Craig Dremann, Redwood City, CA (650) 325-7333
