Bottomlands occupied by greasewood communities are often used intensely by livestock, and may 

 be cultivated. Although Sarcobatus vermiculatus is toxic to both cattle and sheep, it may be browsed 

 and, depending on season and intensity of use, may be an increaser or decreaser under grazing 

 (Hansen et al. 1995). The grass component of these communities is highly palatable and decreases 

 under heavy grazing. One of our sampled stands of SARVER/ELYLAN which was ungrazed for 12 

 or more years had relatively high cover by both shrub (about 38% cover) and grass (about 70%).
