  1. Increase number of livestock

    A randomized, replicated, paired, controlled study in 1936-2009 in eight sagebrush steppe sites in Oregon, USA (Davies et al. 2010) found that increasing the number of livestock decreased grass and herb cover, but did not significantly alter shrub cover. Grass and herb cover in grazed areas were lower (grass: 9%, herb: 17%) than in areas that were not grazed (grass: 18%, herb: 24%). However, shrub cover was not significantly different in grazed (16%) and ungrazed (16%) areas. Eight 2 ha fenced areas excluding livestock were established in 1936, and areas adjacent to the fenced areas were grazed by cattle from 1936-2008. Four 20 m transects were established in each study area and vegetation cover was assessed using a line intercept method.
