DATA RELEASE - Climate, hydrology and riparian vegetation composition data, Grand Canyon, Arizona - Data

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 annually sampled for both geomorphic and vegetation change. Field data contained here were collected from 2012 to 2016 in September and October of each year.

DATA RELEASE - Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099—Data

These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the southern Colorado Plateau. The sites simulated correspond with Inventory and Monitoring plots established by the National Park Service’s Southern Colorado Plateau Network.

DATA RELEASE - The influence of water temperature on salmonid recruitment and adult size in tailwaters across western North America—Data

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length.

DATA RELEASE - Population dynamics of humpback chub, rainbow trout and brown trout in the Colorado River in its Grand Canyon Reach: modelling code and input data

These data were compiled to fit an integrated population model of brown trout in the Glen Canyon reach of the Colorado River and test hypotheses regarding the driver of brown trout population dynamics. Also, data were compiled as inputs for a model to simulate population dynamics and species interactions among brown trout, rainbow trout, and humpback chub in the Colorado River.

DATA RELEASE & MODEL - Continuous Detection PIT Array - Data & Model

These data represent a set of capture histories of rainbow trout captured in the Colorado River and(or) detected on the multiplexer array in the Little Colorado River.

DATA RELEASE - Remote sensing derived maps of tamarisk (2009) and beetle impacts (2013) along 412 km of the Colorado River in the Grand Canyon, Arizona - Data

These data are aerial image-derived, classification maps of tamarisk in a riparian zone of the Colorado River. Two maps are published: 1) a classification of tamarisk from a 0.2 m resolution multispectral image dataset acquired in May 2009, and 2) a classification of tamarisk impacted by the tamarisk beetle from a 0.2 m resolution multispectral image dataset acquired in May 2013.

DATA RELEASE - Landscape-scale wildlife species richness metrics - Data

These raster data represent the results of a case study in Arizona on how vertebrate richness metrics can be used with existing state and federal guidance in wind and solar energy facility siting. Each of the four geodatabases contain eight native terrestrial wildlife group models in Arizona: all vertebrates, amphibians, reptiles, birds, mammals, bats, raptors and long-distance migratory birds...

DATA RELEASE - Variable Terrestrial GPS Telemetry Detection Rates: Parts 1 - 7—Data

Here we explore environmental effects on GPS fix acquisition rates across environmental conditions and detection rates for bias correction of terrestrial GPS-derived large mammal habitat use. We also evaluate patterns in missing data that relate to potential animal activities that change the orientation of antennae and characterize home-range probability of GPS detection for four species.

DATA RELEASE - Flow management and fish density regulate salmonid recruitment and adult size in tailwaters across western North America—Data

These data are a compilation of rainbow and brown trout monitoring data collected by state agencies over several decades in tailwaters downriver of dams in Colorado, Utah, Montana, Wyoming, Idaho, New Mexico, Arizona, California, and Oregon.

DATA RELEASE - Riparian vegetation, Colorado River, and climate: Five decades of spatiotemporal dynamics in the Grand Canyon with river regulation—Data

These data include image-based classifications of total vegetation from 1965, 1973, 1984, 1992, 2002, 2004, 2005, and 2009, and characteristics of the river channel along the riparian area of the Colorado River between Glen Canyon Dam and Lake Mead Reservoir.

DATA RELEASE - Laboratory experiment data—turbidity response to increasing silt and clay concentration-Data

These data were compiled during a laboratory experiment showing the turbidity response to increasing silt and clay concentration. The sediment used for the laboratory experiment was collected in the Grand Canyon study area, from the bank of the Little Colorado River, approximately 1 kilometer upstream from its confluence with the Colorado River.

DATA RELEASE & MODEL - Humpback Chub and Rainbow Trout Joint Mark-Recapture Data and Model, Colorado River, Arizona-Data & Model

These data were compiled for a joint mark-recapture analysis of humpback chub and rainbow trout and include capture histories for both species, and environmental covariates associated with monthly time steps used to measure survival and growth, and environmental covariates used to predict capture probability during each sampling trip.
