The study addresses the problem of forest in-growth due to fire suppression, which reduces grazing land and increases wildfire risk. Through a four-year data collection period at two sites, the researchers examined how thinning, which reduces tree density, impacts understory species diversity and biomass production. The findings indicate that while thinning may not consistently increase species diversity in the short term, it does lead to a significant increase in total understory biomass within a few years, suggesting its potential as a tool for ecological restoration and enhancing forage for livestock. -
