Sustainable management of native forests requires a clear understanding of the conditions that sustain productive capacity in harvested stands. Effective management planning therefore depends on understanding how spatial variation in environmental conditions and anthropogenic use within managed areas influence forest productivity. Using a case study approach, we evaluated how woody biomass recovery responds to local environmental and anthropogenic factors. Data were collected from seven annual production units, and linear models were applied to explain patterns of basal area recovery as a function of precipitation, soil depth and bulk density, plot elevation and slope, grazing indicators, and distance from plots to the farmstead. A significant pattern emerged: plots receiving higher mean annual precipitation and those located farther from the farmstead exhibited larger basal areas. In some cases, however, these relationships were not fully consistent, suggesting that additional environmental and anthropogenic factors contribute to biomass recovery following forest harvesting. Overall, our results support the hypothesis that regeneration and productivity in managed forests depend not only on individual attributes, such as mean precipitation or anthropogenic disturbances, but also on complex interactions among multiple edaphoclimatic and ecological factors, the intensity of human interventions, and their spatial variability across the management area.
