Code for A Landsat based alternative for adaptive habitat management on protected lands Code for A Landsat based alternative for adaptive habitat management on protected lands
This code supports land cover model building, validation and prediction for Alabama's Wildlife Management Areas using remote sensing and field data. It includes R scripts for data preprocessing, spectral indices calculation, model training, validation, and mapping, as well as GIS workflows for spatial alignment and analysis.
North American Breeding Bird Survey (BBS) uncertainty simulation code North American Breeding Bird Survey (BBS) uncertainty simulation code
The North American Breeding Bird Survey (BBS) (https://www.pwrc.usgs.gov/bbs/) has counted birds annually for over fifty-five years. Survey 'routes' each consist of 50 'stops' (point counts) placed along a route path. Inter-stop distances and stop locations can vary from route to route and from year to year, and precise locations of each stop are not typically recorded. Burner et al....
Code to support "Evaluating alternative methods for modeling trap efficiencies of outmigrating juvenile salmonids Code to support "Evaluating alternative methods for modeling trap efficiencies of outmigrating juvenile salmonids
This repository contains R scripts, YAML files, and BASH code to run simulations and evaluate the case study described in "Evaluating alternative methods for modeling trap efficiencies of outmigrating juvenile salmonids" (Walden and Som 2026), and depends on data files available in the accompanying data release https://doi.org/10.5066/P1PN4IHO. The R scripts can be run directly in R...
Software to support A method to implement natural flow regimes for regulated rivers Software to support A method to implement natural flow regimes for regulated rivers
This code shows loading and formatting data, a series of functions to implement flow management constraints, a function to estimate parameters that drive daily discharge predictions, the optimization of the estimating function, and plotting code.
grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases (ver. 1.4.0) grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases (ver. 1.4.0)
Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States. Sage-grouse are one of the most...
Great Plains grassland bird abundance trends Great Plains grassland bird abundance trends
Of all bird guilds in North America, grassland birds have experienced the sharpest declines since 1970. Here, we use the bbsBayes R package to estimate abundance of 50 species of grassland birds from 1984 - 2019 in the Plains states. To run these analyses, open the "GreatPlainsBirds.RProj" file, open the "GreatPlainsBirds_Analysis.R" script file, and run this script. NOTE: Running the...
