Abstract: Restoration of degraded wet meadows found on upland valley floors has been proposed to achieve a range of ecological benefits, including augmenting late‐season streamflow. There are, however, few field and modelling studies documenting hydrologic changes following restoration that can be used to validate this expectation, and published changes in groundwater levels and streamflow following restoration are inconclusive. Here, we assess the streamflow benefit that can be obtained by wet‐meadow restoration using a physically based quantitative analysis. This framework employs a 1‐dimensional linearized Boussinesq equation with a superimposed solution for changes in storage due to groundwater upwelling and...
Abstract (from http://www.sciencedirect.com/science/article/pii/S0034425716302619): Groundwater dependent ecosystems (GDEs) rely on near-surface groundwater. These systems are receiving more attention with rising air temperature, prolonged drought, and where groundwater pumping captures natural groundwater discharge for anthropogenic use. Phreatophyte shrublands, meadows, and riparian areas are GDEs that provide critical habitat for many sensitive species, especially in arid and semi-arid environments. While GDEs are vital for ecosystem services and function, their long-term (i.e. ~ 30 years) spatial and temporal variability is poorly understood with respect to local and regional scale climate, groundwater, and...
The increasing threat of drought to the productivity of US rangelands is a socioeconomic and ecological problem that needs pragmatic solutions. The urgency of this issue has fostered partnerships between private landowners and public natural resource managers to find solutions. The use of North American beaver (Castor canadensis) to increase surface water in arid landscapes is one pre-emptive measure that is gaining interest because of the remarkable ability of beavers to impound water. In places where beaver are no longer present, some landowners and managers are installing artificial structures made of rock and wood with the intention of mimicking effects of beaver dams. Although this ecosystem engineering is...
