Plant composition, shrub biomass, and soil biogeochemistry from an experimental drought treatment on the Colorado Plateau

These data were compiled for a study that investigated the effects of drought seasonality and plant community composition in a dryland ecosystem. In 2015 U.S. Geological Survey ecologists recorded vegetation and soil moisture data in 36 experimental plots which manipulated precipitation in two plant community types. The experiment consisted of three precipitation treatments: control (ambient precipitation), cool-season drought (-66% ambient precipitation November-April), and warm-season drought (-66% ambient precipitation May-October), applied in two plant communities (perennial grasses with or without a large shrub, Ephedra viridis) over a three-year period. These data were collected from 2015 to 2022 near Canyonlands...

Meteorological measurements from five weather stations in Grand and San Juan Counties in southeastern Utah (ver. 2.0, April 2023)

These data were compiled from six automated weather stations that together provide several points in the meteorological record across a latitudinal and elevational gradient in southeastern Utah. Recorded data from these weather stations are associated with several different studies. Meteorological data are important for quantifying short term weather events as well as longer term climate trends. Spatially separated precipitation gauges allow for better characterization of the heterogeneity of precipitation events. These data were collected from six locations running from north to south in southeast Utah. All of the weather stations use Campbell Scientific data loggers and data are collected daily via telecommunications...

Biocrust cover, vegetation, and climate data from a protected grassland within Canyonlands National Park, Utah (ver. 2.0, Sept. 2023)

These tabular data were compiled for/to monitor vegetation and biocrust cover in a never grazed grassland located in Canyonlands National Park. An objective, or objectives, of our study was to document potential changes in biocrust and vegetation cover and species composition as related to changes in land use and climate change. These data represent a timeseries of long-term vegetation and biocrust monitoring plots, dating from 1996 to 2021. These data were collected at/in Virginia Park, Needles District of Canyonlands National Park, Utah. These data were collected by the U.S. Geological Survey, Southwest Biological Research Center in coordination with the US National Park Service. Data were collected via field...

Seasonal ecophysiological measurement data from December 2015 to September 2016, southeastern Utah

These data were compiled to investigate differentiation in physiological activity varies through time for different functional groups. These include the seasonal progress of 13 plant species representing perennial C3 shrub, C3 grass, C4 grass, and annual forb functional groups of the Colorado Plateau, USA. These data can be used to test for differences in carbon assimilation strategies (SeasonalEcophyAciData) and how photosynthetic rates related to climate (SeasonalEcophyMonthlyData). Data can be arranged at the seasonal, annual, species-, or functional group-levels to compare multi-level processes.
