Dear Penny and all:

My hat is off to you for working on this issue for a very long time!

I agree that cheatgrass is a very big problem, and quite a challenge 
for wildlands managers.  I also agree that any bright three-year-old, 
not to mention third-grader, should be able to recognize the value of 
shade in soil moisture conservation; the same should be true for most 
of the other factors I mentioned.  But it is also human nature to 
overlook the obvious, so we have to patient with those who do, and 
thank those who write up "the obvious" as dissertations.  Some years 
ago I did a field trial that illustrated the value of almost any kind 
of cover to soil moisture preservation.

The restoration of something resembling the complex ecosystem that 
preceded the alien invasion can be quite effective in minimizing the 
adverse effects, populations, and reproductive success of alien plant 
species.  However, this can't always be done under the conditions of 
continual disturbance, such as that caused by the presence of alien 
animal species such as livestock.  I believe that the potential for 
restoration as a tool for combatting alien plant species domination 
is inadequately explored.  However, Jayne Belknap 
(http://geochange.er.usgs.gov/sw/impacts/biology/crypto/) and others 
have done considerable work with cryptobiotic (cryptogamic) soil 
crust communities in the Great Basin region, and I suspect that the 
restoration of these communities would go a long way toward reducing 
the adverse effects of many alien plant species.  Just planting a few 
shrub and tree species might help, but restoring a disturbed area to 
ecosystem health requires a comprehensive approach.  But you can 
start by planting pinyons and junipers and "understory" 
shrubs--whatever you can.  Can't hurt!  But keep them widely 
spaced.  Trim them up for fire resistance--if you can spare the 
time.  Even one tree per acre or ten acres would help--I'm in favor 
of treating more area less intensively in most cases, even though 
"creating" a "woodland" is more satisfying.  Just having them close 
enough for the pinyon jays and other interdependent creatures can get 
from one to another and survive is often good enough.

There are lots of effects of pinyon removal, but you no doubt know 
them as well as I, so I won't blab on about them.

Good luck!
