Streamside herbaceous vegetation response to hydrologic restoration on the San Pedro River, Arizona

Ecohydrology, 2009
AbstractRecovery of physical conditions and processes is increasingly emphasized in ecosystem restoration. We examined a restoration project aimed at recovery of groundwater levels and base flows on an undammed desert river. We sampled streamside plant communities and hydrology annually (2003–2008) at six restoration sites at two farms (Three Links ...
