Hi Elizabeth,

I'm not the grad student you're looking for, but from what I understand, 
Creosote (Larrea tridentata) is one of the most plentiful plants in the 
American Southwest, to the point of being considered invasive in some 
areas, and depending on how that amount is gathered over a certain area I 
would imagine it to be quite sustainable. I did find a reference for you:

Whitson, T.D. (ed.) et al. 1996. Weeds of the West. Western Society of 
Weed Science in cooperation with Cooperative Extension Services, 
University of Wyoming. Laramie, Wyoming. 630pp.

Best Regards,
Eden
