Popis: We evaluated the effectiveness of four fire hazard mitigation techniques in pinon-juniper forests of the Davis Mountains Preserve in West Texas. Four replicate fuel treatments (thin only, thin + burn, burn only, and control) were implemented to assess the effects of fire and fire surrogates on fuel loadings. The results suggested that the thin only and the thin + burn treatments significantly altered fuel loadings. The thin + burn treatment resulted in a 63% reduction in tree density, the thin only treatment resulted in a 23% reduction, and the burn only treatment showed an 8% reduction. Seedling density and tree basal area were not significantly affected by the treatments. Although thinning and thinning + burning were the most effective for reducing live fuels, they generated significant increases in surface fuels. Our results suggest that more aggressive thinning operations that target larger trees and prescribed burning during hotter, drier conditions could enhance future fuel management treatments in ...
