Grassland Bird Avian Impact Offset Method GIS Tool Grassland Bird Avian Impact Offset Method GIS Tool
The United States Fish and Wildlife Service Habitat and Population Evaluation Team (HAPET) and United States Geological Survey have updated an ArcGIS script tool that was used to apply what is called the The Avian-Impact Offset Method (AIOM), which was developed to facilitate the estimation of offsets that compensate for behavioral avoidance or displacement resulting in anthropogenic...
Code to evaluate detection probabilities of limestone salamanders (Hydromantes brunus) with eDNA and visual encounter surveys Code to evaluate detection probabilities of limestone salamanders (Hydromantes brunus) with eDNA and visual encounter surveys
The code in this repository generates and analyzes directed acyclic graphs (DAGs) representing hypotheses about variables affecting the occurrence and surface availability of Plethodon salamanders in northern California; formats data from field surveys and and laboratory results for analysis; and analyzes multi-scale integrated occupancy models, including model selection, to evaluate the...
pywatershed v3.0.0 pywatershed v3.0.0
The version 3.0 release of pywatershed contains two major new areas of development: stream temperature representation, and agriculture irrigation estimation. The stream temperature representation reproduces the capabilities from PRMS 5.2.1.1. To this end, the following new classes have been implemented in pywatershed: PRMSStreamTemp, PRMSStreamTempHumidityCBH...
MODFLOW 6: USGS Modular Hydrologic Model MODFLOW 6: USGS Modular Hydrologic Model
MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey.
Planetary Analysis Ready Data Search Tools Planetary Analysis Ready Data Search Tools
Search tools for ArcGIS Pro and QGIS for searching USGS Planetary Analysis Ready Data (ARD) and streaming cloud optimized GeoTIFFs (COGs) into desktop GIS applications. All ARD targets, collections and asset keys are populated dynamically so as new data are released users will have access through these search tools.
ncview R package ncview R package
The {ncview} package was developed out of a need to quickly visualize and compare NetCDF data. It was developed primarily to work with NetCDF outputs from the Joint Ecosystem Modeling (JEM) lab’s jemnetcdfio package3. An effort was made to make the methods robust enough to handle gridded NetCDF data from other sources, but the package may require modifications or extensions for some use...
Analysis of trends in groundwater quality across the conterminous United States for 2002–2021 Analysis of trends in groundwater quality across the conterminous United States for 2002–2021
This repository contains a reproducible data pipeline, implemented in R using the targets framework, that analyzes trends in groundwater quality across the conterminous United States for the period 2002–2021. The pipeline fetches monitoring well network data and constituent observations from USGS ScienceBase, formats and joins these observations with spatial information (well network...
Mississippi Macrophytes HMSC Mississippi Macrophytes HMSC
This repository contains analysis codes to reproduce the key findings reported in the manuscript, "Re-Oligotrophication Over 20 years Contributed to Macrophyte Community Shifts and Recovery in the Upper Mississippi River." The supporting data has been released as a USGS data release: Larson, D., Rohweder, J., Jankowski, K.J., and Jones, M., 2026, Macrophyte Communities and Environmental...
Alaska Landbird Monitoring Survey - Population Trend Analysis Alaska Landbird Monitoring Survey - Population Trend Analysis
This code release implements three hierarchical Bayesian population trend models for Alaskan breeding landbirds, following the methods of Handel and Sauer (2017) and Amundson et al. (2014). The models use point-count data from the Alaska Landbird Monitoring Survey (ALMS; off-road points in Bird Conservation Regions 4 and 5) and the North American Breeding Bird Survey (BBS; roadside...
Analysis of water supply trends across the conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands for water years 1983–2021 Analysis of water supply trends across the conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands for water years 1983–2021
This software repository contains code which does two distinct but related tasks for use in the National Integrated Water Availability Assessment (IWAA), version 1b, Trends chapter. First, it assigns hydroclimatic regions and aggregated hydroclimatic regions to 12-digit hydrologic unit codes (HUC12s) in Hawaii, Puerto Rico, and Alaska. Second, it generates tables and figures used in the...
eversparrow eversparrow
EverSparrow is a spatially explicit Bayesian model of Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis) presence that quantifies the relationships between environmental factors and CSSS presence. Using hydrologic variables such as mean 4-year hydroperiod and maximum depth, fire history, and woody vegetation across the range of the CSSS, EverSparrow provides weekly...
