Wildlife Wrangler
The abundance of wildlife occurrence datasets that are currently accessible can be valuable for efforts such as species distribution modeling and range delineation. However, the task of downloading and filtering occurrence records is often complex due to errors and uncertainties that are present in datasets. This repository provides a high-level framework for acquiring and filtering occurrence dat
Multi-objective Modeling as a Decision-support Tool for Feral Horse Management
Decisions related to controversial problems in natural resource management receive the greatest support when they account for multiple objectives of stakeholders in a structured and transparent fashion. In the United States, management of feral horses (Equus caballus) is a controversial multi-objective problem because disparate stakeholder groups have varying objectives and opinions about how to m

Science-based Management of Ravens Tool (SMaRT)
The Science-based Management of Ravens Tool (SMaRT) supports a science-based adaptive management framework that incorporates recent quantitative analyses and mapping products for addressing areas with elevated common raven (Corvus corax) numbers and minimizing potential adverse impacts to sensitive species, agricultural damage, and human safety (Dettenmaier et al. 2021). This is a web-based applic

"growth_analysis.R"
-An R script to fit the von Bertalanffy growth model to growth data
from San Francisco gartersnakes. The von Bertalanffy growth model is fit using JAGS software (Plummer 2003), and is based on the model presented in Armstrong and Brooks (2013).
"survival_analysis.R"
-An R script to fit the robust-design Cormack-Jolly-Seber model to capture-mark-recapture data from
poscrptR
poscrptR is a simple R package with the sole purpose of distributing a shiny app
for predicting post-fire conifer regeneration. Learn more about shiny apps here.
GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool
The Groundwater/Surface-Water Method Selection Tool (GW/SW-MST) is a spreadsheet-based tool to help practitioners identify methods for use in groundwater/surface-water (GW/SW) exchange and hyporheic studies.
GW/SW exchange and hyporheic processes are topics receiving increasing attention from the hydrologic community. Hydraulic, chemical, temperature, geophysical, and remote sensing methods are u
MODFLOW-NWT: A Newton Formulation for MODFLOW-2005
MODFLOW-NWT is a Newton-Raphson formulation for MODFLOW-2005 to improve solution of unconfined groundwater-flow problems. MODFLOW-NWT is a standalone program that is intended for solving problems involving drying and rewetting nonlinearities of the unconfined groundwater-flow equation.
POPMAPS: An R package to estimate ancestry probability surfaces
This software code was developed to estimate the probability that individuals found at a geographic location will belong to the same genetic cluster as individuals at the nearest empirical sampling location for which ancestry is known. POPMAPS includes 5 main functions to calculate and visualize these results (see Table 1 for functions and arguments). Population assignment coefficients and a raste
SolVES
SolVES is a tool for modeling and mapping social survey response data in relation to explanatory environmental variables. SolVES 4.0 was developed as open-source software with Python and uses the free software packages QGIS for its user interface and PostgreSQL spatially enabled by PostGIS for its source database. Updates to the previous version include minor changes to the source database and use
