متن کاملHydrologic Processes in the Pinyon-Juniper Woodlands: A Literature Review
Hydrologic processes in the pinyon-juniper woodlands of the western region of the United States are variable because of the inherent interactions among the occurring precipitation regimes, geomorphological settings, and edaphic conditions that characterize the ecosystem. A wide range of past and present land-use practices further complicates comprehensive evaluations of these hydrologic process...
متن کاملEffect of Pinyon–Juniper Tree Cover on the Soil Seed Bank
As pinyon–juniper (specifically, Pinus monophylla and Juniperus osteosperma) woodlands in the western United States increase in distribution and density, understory growth declines and the occurrence of crown fires increases, leaving mountainsides open to both soil erosion and invasion by exotic species. We examined if the loss in understory cover that occurred with increasing tree cover was re...

متن کاملRelationships between expanding pinyon–juniper cover and topography in the central Great Basin, Nevada
Land-cover change is a major component of global change (Foley et al., 2005). Many forms of land-cover change, such as deforestation and urbanization, are directly associated with land use. Other land-cover changes, such as melting of permafrost, may be indirectly associated with human activity via anthropogenically induced climate change. Further changes in land cover, such as the expansion of...
