Unsaturated and Saturated Hydraulic Parameters of Soils at the East River Watershed, Colorado Calculated using the Pedotransfer Function Method

The purpose of the data package is to present the results of calculations of the following unsaturated-saturated hydraulic parameters of soils of the East River Watershed, Colorado: fully saturated water content (Qs), residual saturation (Qr), van genuchten parameters alpha and n, field capacity (FC

1 m Resolution Multiscale Height-above-stream Wetness Index for the Upper Gunnison Domain

This map is a soil moisture proxy derived from analysis of the UG 1m hydrologically corrected digital elevation model. The intuition behind this map is that areas that have flat topography and are near the elevation of local streams are likely to have high soil moisture. This index builds on the wor

1 m Resolution 4-band orthomosaic for the Upper Gunnison Basin derived from September 2019 NAIP Imagery

This is a 1m resolution aerial imagery orthomosaic resampled from 0.6m 4-band orthoimagery collected on September 14th 2019 as part of the USDA National Aerial Imagery Program. The original NAIP tiles were reprojected, mosaiced and bilinearly resampled to the standard UG 1m grid, and compressed usin

1 m Resolution NDVI for the Upper Gunnison Basin derived from September 2019 NAIP Imagery

This is a 1m resolution map of Normalized Differential Vegetation Index (NDVI) derived from resampled 0.6m 4-band orthoimagery collected as part of the USDA National Aerial Imagery Program. The NAIP tiles were mosaiced and bilinearly resampled to the standard UG 1m grid before calculating NDVI as (N

1 m Resolution Basic Landcover Map for the Upper Gunnison Domain Derived from NAIP Imagery and LiDAR

This is 1 meter resolution landcover map developed for the RMBL Spatial Data Platform. Source datasets include 2017 and 2019 4-band imagery from the National Aerial Imagery Program, and 2019 LiDAR data collected by Quantum Geospatial for the Colorado Hazard Mapping Program. The numeric codes for the

1 m Resolution topographic slope for the Upper Gunnison Basin derived from 2015 and 2019 LiDAR data.

This is a 1 m resolution map of topographic slope (measured in degrees) computed using a 3*3 pixel kernel and Horn's formula. It is derived from a 1m resolution Digital Elevation Model (DEM) for the Upper Gunnison River derived from public LiDAR datasets. The primary data source was a 2019 LiDAR col

1 m Resolution topographic aspect "westness" for the Upper Gunnison Basin derived from 2015 and 2019 LiDAR data

This is a 1 m resolution map of the relative "westness" of topographic aspect, computed from the cosine of the topographic aspect using the equation: cos(aspect_radians) * -1 Where the aspect is computed clockwise with east having a value of 0. In this map, east-facing aspects have a value of -1 and

The Gothic earthflow revisited: a chronosequence examination of colonization on a subalpine earthflow

A chronosequence study of permanent plots spanning 45 years on a 70-year-old subalpine earthflow in south-western Colorado suggests that it is the severe microclimate of the earthflow which is limiting further colonization of the site.

Diel feeding and positioning periodicity of a grazing mayfly in a trout stream and a fishless stream

We studied the feeding and positioning periodicity on natural substrates of the overwintering and fast-growing summer generations of a grazing mayfly, Baetis bicaudatus, in a third-order trout stream and a fishless, first-order tributary in western Colorado. At 4-h intervals over 24-h, we recorded t

Diapause and the host plant affiliations of lycaenid butterflies

Results of three years of study on the host plant affiliations of two lycaenid butterfly species (Lycaenidae) suggest that differences between the two butterflies in host plant range, plant tissue oviposited on by adults and consumed by larvae, larval growth rates, and adult flight season may be con
