Abstract:
Watershed response following fire is affected by the interaction of soil, plant and hydrologic processes.
The role of vegetation within the hydrologic cycle is well established in the literature, affecting many processes from snowpack to evapotranspiration. Additionally, the role of plants and associated fungi in soil aggregation and structure is also well documented. Many southwestern U.S. plant communities have strong mycorrhizal associations, with plant and fungal mycombiants affecting the recovery of soil cover and structural characteristics. Declines in infiltration rates and soil structural parameters are associated with the decline in vegetation. Strong correlations (p
