Patrick Donnelly proposes monitoring phragmites in Great Salt Lake Basin using satellite imagery
The Great Salt Lake Advisory Council has taken significant steps toward enhancing the management of phragmites, an invasive plant species threatening the ecosystem of the Great Salt Lake Basin. During their recent meeting on September 10, 2025, council members discussed a groundbreaking proposal by Patrick Donnelly to utilize cloud computing and satellite imagery for large-scale monitoring of phragmites across the entire basin.

This innovative approach aims to provide accurate data essential for evaluating treatment success and supporting wildlife habitat analysis and water use assessments. The council emphasized the importance of ongoing mapping efforts to maintain precise data, which is crucial for effective management decisions regarding phragmites treatment.

Donnelly's proposal aligns with recent research from Utah State University, where researchers are set to publish findings on annual phragmites regeneration at local refuges. This research will contribute to a better understanding of the invasive species' impact and the effectiveness of control measures.

The council highlighted the need to quantify trends in phragmites management, moving beyond anecdotal evidence to provide concrete data on the success of treatment efforts. By demonstrating measurable reductions in phragmites coverage, the council aims to strengthen funding requests and public communications regarding their management strategies.

In summary, the Great Salt Lake Advisory Council is committed to advancing its phragmites management efforts through innovative technology and ongoing research, ensuring the protection and sustainability of the Great Salt Lake ecosystem for future generations.
