[RWG] Ecology Vegetation surveys and mapping Releve methodology CNPS Megatransect Dremann Re: New map of roadside weeds & natives from Jackpot to Wells, Nevada

[Wayne Tyson]

Dear Craig,

This is most interesting, and shows a lot of 
work. I have a few suggestions, based on what you 
have submitted. I full well realize that this is 
more than I have done, or, as far as I know, 
anyone else has done, and if you can't follow my 
suggestions, do continue to do what you've been doing.

Please try to be precise in at least some 
location information, such as providing mile-post 
markers or other permanent geographical 
identification that indicates the boundaries 
between your classifications. Please also state 
your methodology for determining (estimating) 
plant population, diversity, and density 
relationships or “cover,” perhaps using some fast 
and simple but accepted technique like 
Braun-Blanquet/relevé; for example, the technique 
used by the California Native Plant Society--see, 
for example, http://www.cnps.org/archives/forms/releve.pdf.

These two things should make you research 
acceptable for publication in a journal, and 
establish a methodology for other to follow. Most 
importantly, it will compound the value of the 
very important work you are doing.

Best,
WT
