USGS Land Treatment Digital Library Data Release: A centralized archive for land treatment tabular and spatial data (ver. 2.0, May 2020)

Across the country, public land managers make hundreds of decisions each year that influence landscapes and ecosystems within the lands they manage. Many of these decisions involve vegetation manipulations known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. Data on these land treatment...

Streamflow Permanence Class rasters (PROSPER), 2004-2016, (ver. 2.0, February 2019)

Streamflow Permanence Class (SPC) rasters represent the classification of the raw streamflow permanence probabilities produced by the PRObability of Streamflow PERmanence (PROSPER) model into categorical wet and dry classes, annually for years 2004 through 2016, and overall mean. Raw probabilities were classified into a -5 (dry) to +5 (wet) scale based on the spatially varia

Total Mercury and Methylmercury in Riparian Songbirds and Aquatic Invertebrates from the Willamette Valley, Oregon, 2013-2014

This dataset includes bird species, invertebrate order and family, sample identification codes, capture date, latitude, longitude, habitat, site name, bird age, total mercury concentrations in bird blood, and methylmercury concentrations in whole body aquatic invertebrates.

Streamflow Permanence Probability rasters (PROSPER), 2004-2016, (ver. 2.0, February 2019)

Streamflow Permanence Probability (SPP) rasters represent the raw streamflow permanence probabilities produced by the PRObability of Streamflow PERmanence (PROSPER) model, annually for years 2004 through 2016, and overall mean and standard deviation. The PROSPER model is a GIS raster-based empirical model of probabilistic predictions of a stream channel having year-round flow for any

Tackifier impacts on growth of Great Basin moss Bryum argenteum, 2017-2018

The dataset supports a larger study that examined the impacts of three tackifiers (guar, psyllium, and polyacrylamide) on growth of two dryland mosses (Bryum argenteum and Syntrichia ruralis). Moss fragments were grown in petri dishes and subjected to individual tackifiers in one of three possible concentrations (0.5x, 1x, or 2x) of the respective manufacturer's recommended

Data supporting the study of tree species' access to rock-derived nutrients, Tillamook State Forest, 2015

This dataset describes foliar and soil chemistry and isotopes for six tree species in Tillamook State Forest, 2015.

Biological soil crust cover from the Taylor Grazing Act Exclosures

Seven exclosures that were part of the original 28 Taylor Grazing Act exclosures across northern Nevada were surveyed for cover of biological soil crusts in May 2018. Surveys consisted of 15 quadrats both inside and outside of the exclosures. Quadrats were used to measure biocrust cover via point-intercept at 39 vertices within each quadrat. Cattle grazing outside of the exclosures was...

Floodplain data from the Hoh, Elwha, Queets, and Quinault Rivers in Olympic National Park, 1939-2013

Floodplain margins, defined as the unvegetated portion of the active flow zone, were determined for four rivers in Olympic National Park, Washington, USA, from the 2013 National Agriculture Imagery Program (NAIP) orthophotomosaic. Transects were established orthogonal to the active river corridor (braids) across the width of the floodplain from point locations placed at 250 m in

Floodplain data from the Hoh River in Olympic National Park, 1939-2013

Floodplain characteristics were quantified for the Hoh River in Olympic National Park, Washington, USA, using orthophoto imagery taken between 1939-2013.

Tackifier impacts on growth of Great Basin mosses Bryum argenteum and Syntrichia ruralis, a growth chamber study, 2017-2018

The dataset supports a larger study that examined the impacts of three tackifiers (guar, psyllium, and polyacrylamide) on growth of two dryland mosses (Bryum argenteum and Syntrichia ruralis). Moss fragments were grown in petri dishes and subjected to individual tackifiers in one of three possible concentrations (0.5x, 1x, or 2x) of the respective manufacturer's recommended

Nutrients, estrogenicity, and fecal indicators in surface water collected from wetlands in the Klamath Marsh National Wildlife Refuge, Oregon, 2017-2018

The data included here were gathered to determine the effects of cattle grazing on wetland water quality in the Klamath National Wildlife Refuge in Oregon. Surface water samples from sites representing a range of grazing histories were collected between June and October in 2017 and 2018. Samples were analyzed for nutrients (ammonia, nitrate plus nitrite, nitrite, and orthophosphate),
