Ecophysiology of riparian cottonwoods: stream flow dependency, water relations and restoration.
Cottonwoods (Populus spp.) are adapted to riparian or floodplain zones throughout the Northern Hemisphere; they are also used as parents for fast-growing hybrid poplars. We review recent ecophysiological studies of the native cottonwoods Populus angustifolia James, P. balsamifera L., P. deltoides Marsh., P. fremontii S. Watson and P. trichocarpa T. & G. in North America, and P. nigra L. in Euro...
متن کاملResponses of Riparian Cottonwoods to Alluvial Water Table Declines.
/ Human demands for surface and shallow alluvial groundwater have contributed to the loss, fragmentation, and simplification of riparian ecosystems. Populus species typically dominate riparian ecosystems throughout arid and semiarid regions of North American and efforts to minimize loss of riparian Populus requires an integrated understanding of the role of surface and groundwater dynamics in t...
متن کاملRiparian vegetated buffer strips in water-quality restoration and stream management
1. A review is presented of the literature on riparian vegetated buffCT strips (VBS) for use in stream-water-quality restoration and limitations associated with their use are discussed. The results are also presented of recent investigations on the effectiveness of a forested and a grass vegetated buffer strip for reducing shallow subsurface inputs of nutrients from agriculture to a stream in c...
متن کاملEcophysiology of riparian cottonwood and willow before, during, and after two years of soil water removal.
Riparian cottonwood/willow forest assemblages are highly valued in the southwestern United States for their wildlife habitat, biodiversity, and watershed protection. Yet these forests are under considerable threat from climate change impacts on water resources and land-use activities to support human enterprise. Stream diversions, groundwater pumping, and extended drought have resulted in the d...
متن کاملStream and Riparian Ecology
Water is a valuable resource for humans (direct consumption, power, irrigation, industry) and provides essential habitat for many organisms, including highly valued fish species such as salmonids. Aquatic habitat is influenced by processes active not only in the near-stream (riparian) zone (e.g., provision of shade) but also over the entire watershed (e.g., hillslope hydrologic processes that c...
