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.
This report, contracted by the Utah Division of Wildlife Resources (UDWR) describes a vegetation-monitoring trip that was conducted on May 9-12, 2022, by John Leary (RiversEdge West) and Wally Macfarlane (Utah State University) from Bonanza Bridge to Asphalt Wash and a subsequent vegetation data analysis. The vegetation-monitoring trip and analysis evaluated the effectiveness of prior non-native vegetation removal efforts and established the baseline condition for planned upcoming treatments.
Remote sensing methods are commonly used to monitor the invasive riparian shrub tamarisk (Tamarix spp.) and its response to the northern tamarisk beetle (Diorhabda carinulata), a specialized herbivore introduced as a biocontrol agent to control tamarisk in the Southwest USA in 2001.
Stabler and Still estimate density and standing biomass of tamarisk along waterways in a northwest to southeast transect in Oklahoma to test the hypothesis that environmental conditions in northwest Oklahoma would make successful invasion by tamarisk more likely. They found that the invasive potential of tamarisk in Oklahoma is likely limited by streamflow and climate but not by soil salinity.

Vegetation response to invasive Tamarix control in southwestern U.S. rivers: a collaborative study including 416 sites

Rapid Monitoring Protocol used in the DRRP
Sher at al. perform a comprehensive and detailed analysis of the vegetation response to a single watershed-scale restoration effort that includes 40 sites along the Dolores River from 2010-2014.

The purpose of the Stream Stewardship and Recovery Handbook is to create an educational resource for private landowners to better understand their streamside properties in the context of the larger watershed, what they can do to practice good stream stewardship and when/how they should engage outside help for stewardship or recovery projects.
Using high-resolution multitemporal, multispectral data, the authors classified tamarisk defoliation in the Glen Canyon area in Arizona. The high spatial resolution classification provides key information to effectively inform restoration treatments regarding where and how much mechanical removal or controlled burning could be performed.
