Whither the Rangeland?: Protection and Conversion in California's Rangeland Ecosystems

open access: yesPLoS ONE, 2014
Land use change in rangeland ecosystems is pervasive throughout the western United States with widespread ecological, social and economic implications. In California, rangeland habitats have high biodiversity value, provide significant habitat connectivity and form the foundation for a number of ecosystem services.

THRESHOLD RANGELAND CONDITION FOR RANGELAND RESTORATION INVESTMENTS AND THE FINANCIAL EQUIVALENT OF LIVEWEIGHT LOSSES DUE TO RANGELAND DEGRADATION [PDF]

open access: yesApplied Ecology and Environmental Research, 2019
In this paper, the relations between live weight (LW) gain of the grazing cows and rangeland condition (RC), LW gain and concentrate supplement and LW gain and genetics of the grazing cows were investigated to quantify LW and body condition score (BCS) losses driven by rangeland degradation to estimate the threshold RC over which rangelands can ...
