Mechanism
The Mid and Shortgrass Savannah community (1.2) is the most short-lived community on this very fragile Steep Adobe site unless the transition is halted or reversed. If left in place, the factors that caused the transition from the reference community will accelerate and in a relatively short time cause the transition from this community to the Oak/Juniper/Shrub Complex community (2.1).
Mechanism
The potential for restoring this community to the reference state within a reasonable amount of time is extremely low. With the possible exception of some lower slopes, decades of transition have robbed the site of the soil properties, species diversity, site integrity, and hydrological features essential for restoration. The difficulties of attempting brush management are usually prohibitive for most land uses due to the terrain and the high extensive cost requirements. Prescribed grazing or even reducing the amount of grazing by livestock can also assist in the development of desirable habitat for wildlife and the recreational activities that accompany it.
