Use prescribed burning to control trees
A randomized, replicated, controlled, before-and-after trial in 2003-2004 in two sagebrush ecosystems in California, USA (Ellsworth & Kauffman 2010) found that using fire to control western juniper Juniperus occidentalis did not change the cover of two out of three grass species after one year. In both sites the cover of squirreltail Hordeum jubatum and sandberg bluegrass Poa secunda did not significantly differ after burning from the cover before burning, and cover did not differ from areas that had not been burned (no data reported). However, in one of the two sites the cover of bluebunch wheatgrass Pseudoroegneria spicata was lower after burning than before burning, and cover was lower in areas that had been burned than in areas that had not been burned (results presented as model results). Five blocks were established in two sites. Each block consisted of three 0.4 ha plots, two of which were burned and one of which was left unburnt. Cover of grasses was estimated in 2004 using two 30 x 60 cm plots within each 0.4 ha plot.
