These data were compiled for monitoring riparian vegetation change along the Colorado River. This file contains data recorded at 42 sandbars between Lees Ferry and Diamond Creek, AZ, which are sampled for both geomorphic and vegetation change annually. Field data contained here were collected from 2012 to 2016 in September and October of each year. Plant species cover values in 5441 1m^2 quadrat frames, locations and elevations of those sampling frames, slope and aspect, sample dates, temperature and precipitation data, and flood frequency parameters were either recorded in the field or calculated. Annual and seasonal climate variables were estimated from eight weather stations distributed along the river corridor from data aquired [...]

The purpose of these data were to assess how closely riparian plant communities track hydrological and climatic variation in space, and how interactions among hydrological and climatic filters influence success of flow management strategies? These data were used to explore possible linkages between hydrological and climatic variables with regards to their impact on riparian vegetation and predicting resource responses to environmental change.
