DATA RELEASE - Community-level riparian plant traits, Colorado River, Grand Canyon, 2013-2015

Data were compiled based on field observations and available literature. Field data were collected on sandbars along the Colorado River through Grand Canyon between river miles 0 and 226 and included plant cover and trait measurements. Plant height and photosynthetic pathway were gleaned from the literature. Trait values were converted to a community-level value.

DATA RELEASE - Stream Drift Sampling in Arizona, 2014

Data were compiled from field drift collections and from a meta-analysis of published drift literature. Field data were collected in 2014 from the Colorado River downstream of Glen Canyon Dam, Arizona. Data represent flow meter measurements taken at the mouth and adjacent to a drift net, and suspended solids concentrations collected by the drift net, over varying net deployment durations.

Riparian vegetation classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data

These data are classification maps of total riparian vegetation along the Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013. The total vegetation data have the same 0.2-meter ground resolution as the imagery. These data have not undergone a...
