  1. Sow seeds

    A replicated site comparison study in 1984–1999 in eleven sagebrush shrubland sites affected by wildfire in Nevada, USA (Eiswerth et al. 2009) found that sowing seed containing Wyoming big sagebrush Artemisia tridentata wyomingensis increased the density of Wyoming big sagebrush plants. Areas where Wyoming big sagebrush seed was sown had a higher density of Wyoming big sagebrush than areas where their seed was not sown (results presented as model results). All study sites burned in wildfires in 1984-1997 and seed mixes containing Wyoming big sagebrush seed sown at an unspecified number of sites, while other sites were either not sown with seed or sown with mixes that did not contain Wyoming big sagebrush seed. Wyoming big sagebrush density was recorded at least once at all sites following the sowing of seed.
