Özet (Çeviri)

Fire suppression techniques over the last century have increased tree densities and altered the ecological processes of montane forests within New Mexico. Alternative forest silviculture treatments might reduce wildfire risk and improve water yield and herbaceous cover. This study's goals were to 1) determine how forest silvicultural thinning treatments affect understory and overstory vegetation cover and 2) determine how forest silvicultural treatments affect runoff and sediment yield. Thinning treatments were a control, pile, innerspace (space between piles), and lop-scatter. The effect of treatments on herbaceous and overstory cover were assessed with a fixed-plot layout at treatment sites, where 2014 post-treatment results were compared to 2008 post-treatment measurements. Runoff and sediment yield were measured utilizing one-hour rainfall simulations at the runoff ring scale (1 m2). Results showed forest thinning treatments significantly impacted herbaceous vegetation cover, litter cover, bare cover, and canopy cover. In lop-scatter treatments, vegetation cover and canopy cover were higher in 2014 than in 2008. Inner-space plots showed higher bare ground cover percent than in pile and in lop-scatter areas. Litter cover from the control plots resulted in higher cover than both lop-scatter and pile plots on the gentle slopes, while on the steep slopes the cover was only higher than the pile plots. Data suggest that all thinning treatments promote increased vegetative understory cover promote increased vegetative understory cover. There was no significant difference in runoff ratio among the treatments during the dry runs; however, control sites had lower runoff ratios than inner-space, lop-scatter, and pile treatments during the wet runs. During both dry and wet runs, time to runoff initiation was greater on the pile treatments and scatter treatments compared to the control treatments. There were no differences in time to peak runoff among silvicultural treatments during simulated rainfall. During wet runs, sediment yield did not differ by treatment; however, on steep slope sites, sediment yield was higher than on gentle slopes. This study suggests that the combination of thinning and burning silvicultural treatments promotes increased vegetative understory cover; the treatments appear to delay runoff when compared to control plots.
