The SRM Symposium (February 2021) shared some of what’s been learned after at least 10 years post-treatment. Researchers present findings from conifer-encroached and cheatgrass-invaded sites, focusing on: effects of treatments on herbaceous plants, ground surface properties, and hydrologic and erosion processes in woodlands; and on fire behavior and Wyoming big sagebrush in shrub/grass systems, with discussion of ecological costs and benefits of treatments in those systems. A moderated discussion session followed the presentations.
