U.S. Fish & Wildlife Service - Comprehensive Conservation Plan
The Fish and Wildlife Service (USFWS) has been entrusted to manage our nation’s critical wetland resources. Due to conversion in industrial, residential, and agricultural uses, these wetlands have been disappearing at an alarming rate over the last one-hundred years. In order to better care for these resources, all of the refuges are developing long-term Comprehensive Conservation Plans (CCP).
Work with U.S. Fish & Wildlife Service – Reed Canary Grass
Impact of UMESC Science To generate decision-making information needed for refuge managers on how to treat reed canary grass in order to maintain or restore target communities and the wildlife they support.
2019 Illinois Waterway Aerial Image Mosaics 2019 Illinois Waterway Aerial Image Mosaics
The Corps of Engineers' Rock Island District is planning an unprecedented closure of the Illinois Waterway in 2020 in order to perform required maintenance on locks. Aerial imagery will document river conditions prior to the closure (2019) and after the locks are reopened (2021). Under a separate but related effort, aerial imagery of the entire Illinois Waterway will be collected in 2020...
2018 Emiquon and Spunky Bottoms Preserves, 4-Band Mosaics 2018 Emiquon and Spunky Bottoms Preserves, 4-Band Mosaics
This mosaic was created using high-resolution aerial imagery collected on September 14, 2018 with a Phase One iXU-R 180 aerial camera co-mounted with a Phase One iXU-RS 160 Achromatic camera. The raw image files from the two cameras are combined to create 4-band imagery. The mission was flown at approximately 1,2000 meters above ground level resulting in a ground sample distance of 0.15...
2017 True Color Mosaic, Emiquon Preserve and Spunky Bottoms 2017 True Color Mosaic, Emiquon Preserve and Spunky Bottoms
The true color aerial imagery contained in this mosaic was collected on September 19, 2017 with a Phase One iXU-R 180 aerial camera system. The mission was flown at approximately 1,200 meters above ground level resulting in a ground sample distance of 0.15 meters/pixel (6"/pixel). The area of interest is the Emiquon Preserve and the mosaic is for the purpose of habitat monitoring.
2016 True Color Mosaic, Emiquon Preserve and Surrounding Areas 2016 True Color Mosaic, Emiquon Preserve and Surrounding Areas
The true color aerial imagery contained in this mosaic was collected on September 19, 2016 with a Phase One iXU-R 180 aerial camera system. The mission was flown at approximately 1,200 meters above ground level resulting in a ground sample distance of 0.15 meters/pixel (6"/pixel). The area of interest is the Emiquon Preserve and surrounding areas and the mosaic is for the purpose of...
An evaluation of a reagentless method for the determination of total mercury in aquatic life An evaluation of a reagentless method for the determination of total mercury in aquatic life
Multiple treatment (i.e., drying, chemical digestion, and oxidation) steps are often required during preparation of biological matrices for quantitative analysis of mercury; these multiple steps could potentially lead to systematic errors and poor recovery of the analyte. In this study, the Direct Mercury Analyzer (Milestone Inc., Monroe, CT) was utilized to measure total mercury in fish...

Changes in backwater plant communities from 1975 to 1995 in Navigation Pool 8, Upper Mississippi River Changes in backwater plant communities from 1975 to 1995 in Navigation Pool 8, Upper Mississippi River
Water elevation in the Upper Mississippi River (UMR) is highly regulated by an extensive system of locks and dams. Completion of this system in the 1930s created productive, biologically diverse backwater habitats. The status of plant communities in these backwater areas may now be threatened by several factors, including sediment accumulation, recreational use, and navigation traffic...
