During the ranching era deer and elk were introduced to the island for sport hunting. These non-native herbivores easily grazed upon the endemic island plants which had not adapted to withstand grazing.

As management of the island was nearly finished transferring from the ranchers to the National Park Service, CIR stepped in to install fencing and cages around important plant populations and around newly planted natives around our restoration sites.

When deer and elk were completely removed from the island we underwent the arduous task of removing all of our now-obsolete fencing.

CIR volunteers install fencing around wetland habitat near the top of Lobo Canyon.
