Riparian vegetation data downstream of Glen Canyon Dam in Glen Canyon National Recreation Area and Grand Canyon National Park, AZ from 2014 to 2019

These data were collected by the Grand Canyon Monitoring and Research Center (GCMRC) to support riparian vegetation monitoring along the Colorado River between Glen Canyon Dam and the full pool level of Lake Mead. The objectives of the GCMRC riparian vegetation monitoring program are to annually measure and summarize the status (composition and cover) of native and non-native vascular plant species within the riparian zone of the Colorado River between Glen Canyon Dam and Lake Mead, assess change in the vegetation composition and cover in the riparian zone, as related to geomorphic setting and dam operations, particularly flow regime, and collect data in a manner that can be used by multiple stakeholders and is...

Community-level riparian plant traits, Colorado River, Grand Canyon, 2013-2015—Data

These data were compiled based on field observations and available literature. Field observations of plant cover were made in September and October of 2013 and 2014, while trait measurements were made in September and October of 2014 and 2015. Field data was collected on sandbars along the Colorado River through Grand Canyon between river miles 0 and 226. Field measurements of specific leaf area, stem specific gravity, and total cover. Plant height was taken from the Flora of North America, the Jepson Desert Manual, or A Utah Flora. Seed mass values were available from the Kew Seed Information Database (http://data.kew.org/sid/). Photosynthetic pathway was compiled from published literature. The trait values were...

Plant genetic structure data from riparian areas within the Grand Canyon region in northern Arizona

These data represent nuclear microsatellite data collected from four riparian plant species that occur in and around Grand Canyon National Park: Populus fremontii (POFR), Salix gooddingii (SAGO), Salix exigua (SAEX), and Prosopis glandulosa (PRGL). These data were collected for population genetic analysis to help inform native plant material development in Grand Canyon National Park. Leaf samples were collected at sites spanning 470 km of the Colorado River between Glen Canyon Dam and Lake Mead and in tributaries. Known revegetation areas were not sampled. We aimed to collect leaf tissue from at least 15 individuals at each sample site. If there were fewer than 15 individuals per species at a site, leaf tissue was...
