Hydrologic Processes in the Pinyon-Juniper Woodlands: A Literature Review
نویسندگان
چکیده
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 processes. Heterogeneous vegetative covers make it even more difficult to generalize hydrologic processes and the effects of land management practices on the water balance. Nevertheless, estimates of interception, infiltration, evapotranspiration, soil moisture storage, and hillslope soil erosion of these on-site hydrologic processes have been obtained in plot studies. Estimates of off-site streamflow volumes, sediment yields and transport, and quality of streamflow water are available from the results of watershed-level investigations. Estimates of these respective hydrologic processes are presented in this general technical report.

Patterns of mast production in pinyon and juniper woodlands along a precipitation gradient in central New Mexico (Sevilleta National Wildlife Refuge)
This paper reports on an 8-year continuing project with the Sevilleta Long-Term Ecological Research program (LTER) in central New Mexico aimed at the study of dynamics of woodland ecosystems. The study of mast production was conducted at six experimental woodland sites situated across an elevational gradient of 1500–2000m in proximity to permanent meteorological stations. The dominant woody spe...

متن کاملDifferential tree mortality in response to severe drought: evidence for long-term vegetation shifts
1 Although drought frequency and severity are predicted to increase across numerous continental interiors, the consequences of these changes for dominant plants are largely unknown. Over the last decade, the south-western US has experienced six drought years, including the extreme droughts of 1996 and 2002, which led to widespread tree mortality across northern Arizona. 2 We examined the impact...
متن کاملRestoring grassland savannas from degraded pinyon-juniper woodlands: effects of mechanical overstory reduction and slash treatment alternatives.
Although the distribution and structure of pinyon-juiper woodlands in the southwestern United States are thought to be the result of historic fluctuations in regional climatic conditions, more recent increases in the areal extent, tree density, soil erosion rates and loss of understory plant diversity are attributed to heavy grazing by domestic livestock and interruption of the natural fire reg...
متن کاملBrown-headed Cowbird Behavior and Movements in Relation to Livestock Grazing
The Brown-headed Cowbird (Molothrus ater) is a widespread brood parasite which often engages in a commensalistic feeding relationship with domestic livestock. We studied the behavior of female cowbirds breeding in pinyon–juniper woodlands in New Mexico, USA, on two adjacent sites, one an active cattle ranch, and the other a site that was not grazed by domestic livestock throughout the songbird ...
