SageSTEP scientists have now collected 6 years of post-treatment data on 20 sites throughout the Great Basin, and now have a fairly certain understanding of short-term vegetation response to fire and mechanical treatments on at about half of those sites. While post-treatment recovery to a more desirable condition is evident at some sites (i.e. more bunchgrasses), the warmer and drier sites continue to be dominated by exotic annual grasses. Visual-style multivariate analysis will be used to help illustrate the main causes for variation in treatment response among sites. Jim McIver, Ecologist and SageSTEP Coordinator, Oregon State University, presents.
