An ArcGIS Online (AGOL) page containing historical and predictive maps developed by James Hatten of the USGS for the southwestern willow flycatcher habitat across the southwestern United States. The model outputs a range of probabilities for suitable and less suitable habitat in 20% probability classes. This project shows that the satellite model adequately predicts flycatcher habitat rangewide, but it lacks the ability to predict which patches will be occupied in a given year.

A Field Guide for the Identification and Use of Common Riparian Woody Plants of the Intermountain West and Pacific Northwest Regions
Yellow and Caucasian bluestems are introduced bunchgrass species that are becoming invasive in southwestern States after successfully invading the Central and Southern Great Plains. This field guide serves as the U.S. Forest Service’s recommendations for management of yellow and Caucasian bluestems in forests, woodlands, rangelands, desert, and desert scrub associated with its Southwestern Region. TheSouthwestern Region covers Arizona and New Mexico, which together have 11 national forests.
