Abstract
This resource contains RHESSys model output data from virtual thinning experiments in Sagehen Creek Experimental Forest, Sierra Nevada, CA, produced for the CA Wildlife Conservation Board. The model domain is the experimental hillslope, which allows for subsurface lateral redistribution of upslope water subsidies from thinning. Each thinning scenario is a 15-year simulation varying climate, ecophysiological parameter uncertainty, topographic aspect and elevation, as well as treatment strategies. We primarily consider the effect of thinning intensity, location, and frequency. We simulate a low- and high-intensity treatment by removing 30 or 60% canopy cover, respectively. We vary location by thinning only upslope areas, only riparian areas, or both upslope and riparian areas. The control scenario is an untreated forest. These results are in files dated 91322, "thinwyb" for basin output, "thinwyz" for zone output, "thinwys" for stratum output. We also run a single treatment scenario (30% thinning on S-facing, low-elevation hillslope in both locations) over 50 years and vary thinning frequency to consider interactions between long-term climate, vegetation regrowth, and water yield. The long-term data set is thinwybres102522.csv, just basin output.
