Hydrologic Response To Conifer Removal From An Encroached Mountain Meadow, Gregory F. Van Oosbree
Hydrologic Response To Conifer Removal From An Encroached Mountain Meadow, Gregory F. Van Oosbree
Master's Theses
Meadows in the Sierra Nevada Mountains are an important ecological resource that have degraded in quality and distribution due to several environmental and anthropogenic stressors. The encroachment of conifers beyond forest meadow ecotones is largely responsible for the decline of meadow habitat throughout the past century. Currently, there is little research that quantifies the hydrologic response to removal of conifers encroaching meadows in terms of implicating successful meadow restoration. This study has implemented a before after control intervention (BACI) study design to determine the hydrologic response associated with the removal of conifers from a historic meadow encroached by conifers. The …
