Riverine and riparian ecosystems: effects of dams, water diversion, and land use on ecosystem processes
The effects of water development (dams and diversions) on riparian ecosystems
Current projects include: response of vegetation to Tamarix removal along the Rio Grande and upper Green Rivers; processes governing Tamarix invasion in the western US; the role of hydrochory in structuring plant communities; the effects of dams and diversions on riparian vegetation, strucutred population modeling of riparian plants; streamflow regimes necessary to support riparian vegetation; National riparian definition, classification, and trend monitoring
