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...

Threshold and confidence interval rasters, 2004-2016, Region 17

The threshold raster includes the raw streamflow permanence probability value at a given pixel that represents the estimated critical value to differentiate between wet conditions (above the threshold) and dry conditions (below the threshold). Confidence interval rasters indicate the value above or below the threshold corresponding to the nth percentile of confidence that the pixel is wet (...

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...

Estimated Probabilities from Lidar Models for Marbled Murrelet (Brachyramphus marmoratus) Occupancy in Forest Vegetation Stands in the Siuslaw National Forest, Oregon

We developed a LiDAR-based habitat model for the threatened Marbled Murrelet (MAMU) in the Siuslaw National Forest, Oregon, using a two-step approach. First, we tested the applicability of the LiDAR-based model developed for the Coos Bay District of the Bureau of Land Management (BLM) to the Siuslaw N.F. In the second step, we tested alternative habitat models developed with forest structural...

Land Treatment Exploration Tool

The Land Treatment Exploration Tool is designed for resource managers to use when planning land treatments. The tool provides useful summaries of environmental characteristics of planned treatment areas and facilitates adaptive management practices by comparing those characteristics to other similar treatments within a specified distance or area of interest. ...

Beaver-related Stream Restoration Projects in Western Rangelands

We systematically surveyed federal and state wildlife biologists, hydrological specialists, non-profit organizations, and working groups focused on beaver or wetland restoration in the western U.S. We focused primarily on contacting land managers from states containing some portion of the Great Basin, although many of the projects described in surveys fell outside of this watershed. Some...

Western US Ruggedness Reclassified into 6 Classes

"Vector Ruggedness Measure (VRM) measures terrain ruggedness as the variation in three-dimensional orientation of grid cells within a neighborhood. Vector analysis is used to calculate the dispersion of vectors normal (orthogonal) to grid cells within the specified neighborhood. This method effectively captures variability in slope and aspect into a single measure. Ruggedness values in the...

Exotic and perennial grass cover for pastures in the Soda Fire (2016)

The point data file ("Soda Fire Point and Pasture Data (2016).Point Data.csv") includes 2016 vegetative cover values of exotic annual grass and perennial grass measured within three different types of plots for 75 pastures in the Soda Fire, which burned in 2015: 6m² plot using a grid-point intercept photo software, SamplePoint (Booth et al. 2006), 1m² quadrat using an...

Insect and vegetation community composition and abundance after wildfire and restoration seeding treatments in southwestern Idaho, USA

We conducted the first investigation of insect community responses to post-fire seeding on public rangelands by comparing the composition of insect communities at burned-and-seeded (treatment) and burned-and-unseeded (control) sagebrush-steppe ecological sites in southwestern Idaho. Insect communities in burned areas were compared to unburned (reference) areas. We collected insect and...
