50-year grazing exclosure near Portal, AZ
Audubon's Appleton Whittell Research Ranch
The Research Ranch is a 3100-ha grazing exclosure established in 1968. While grazing has continued outside the fence on several adjacent ranches, the region has not experienced broad desertification, and the vegetation is still primarily perennial grasses. This site makes as excellent comparison site to the 50-yr exclosure in Portal, which has also been continuously grazed outside the fence.
The Portal Project is a long-term experimental site in southeastern Arizona, initiated in 1977, to study the relationship between granivorous rodents, ants and the annual plant communities on the site. Surprising dynamics reveal themselves when you track a community for thirty years! I served as a research assistant on this site, conducting plant and ant censuses, from 2007-2011.
