[PCA] FIRE 07 Great Basin and Southwest conditions Costs for restoration and management Plan? Re: Increase in fires in arid USA maybe result of six reasons

I would to reply to several posts at once. I have worked on this issue for a 
very long time .

The cheatgrasslong been  recognized as the primary fuel problem, but the 
response has been to treat pinyon trees.

"We found that a fire cycle had developed, referred to in recent science 
reports as the 'cheatgrass-wildfire cycle.' This problem is acute in Nevada, 
where the cycle of fire disturbance has spurred the invasive cheat grass to 
alter range and wildlife habitats."

The problem was BAD science created to justify the conversions.  One of my 
favorite moments in pinyon literature- 1998, Dr. David D. Breshears of Los 
Alamos Laboratories wrote a paper on the value of pinyon shade and the role 
of shade in cooling the earth. In short, it took a rocket scientist to write 
a dissertation on an issue every third grader knows. Trees make shade and 
cool the earth. What happens when they are removed in massive quanities?


Bonnie,
>knowing that the vegetation changes caused by climate change will not fit 
>our previous understanding of plant dynamics

I would suggest, that vegetation change is causing much of the climate 
changein the Great Basin

"Historical annual fire starts from lightning on BLM land (1964-96) and 
U.S.D.A. Forest Service land (1970-96) are plotted for each western state to 
show interannual variability and trends. Interannual variability is large in 
all states, but only certain BLM states (primarily in the Great Basin) show 
evidence of increasing fire starts through time. We are in the process of 
analyzing these data further, but we believe that these trends are due 
largely to changes in vegetation type (primarily grasses) which are more 
condusive to ignition by lightning. We are also examining these vegetation 
changes in context of regional climate change."Western Regional Climate
