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),

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

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

Terrestrial salamander captures after the 2003 Clark Fire, Willamette National Forest, OR

Data are the result of fixed-area, time-constrained searches for terrestrial salamanders within and nearby a wildfire-affected area of the Willamette National Forest, OR. The spatial extent of the study was within one kilometer of the border of the Clark fire that burned an area of 2,009 ha in 2003. Site surveys occurred during March and April, 2005. An important feature of the data is th

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

Floodplain characteristics were quantified for the Queets River in Olympic National Park, Washington, USA, using orthophoto imagery taken between 1939-2013. Each zipped folder contains a shapefile and its associated metadata record.

Statistical Tools for Wind and Solar Energy Development and Operations

Solar and wind power development is increasing exponentially in the United States. However, these energy sources may affect wildlife, either directly from collisions with the turbine blades or photovoltaic arrays or indirectly from loss of habitat and migration routes. An important component to understanding the effects of these renewable energy projects on wildlife is accurate and precise...

Streamflow Permanence Probability (SPP) rasters, 2004-2016, overall mean and standard deviation, Region 17

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...

Streamflow Permanence Class (SPC) rasters, 2004-2016, and overall mean, Region 17

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 variable threshold (i.e...
