Summary
A geodatabase was developed to compile mapped abundance raster datasets for 25 species/species groups (e.g., all duckweeds combined) for pools 4, 8, and 13 on the Upper Mississippi River system from 1998-2019. Individual rasters within the geodatabase have scores ranging from 0 (species modeled to be absent at that raster cell) to 100 (highest possible mapped abundance probability at that raster cell). Relative abundance, for submersed species and filamentous algae, represents the sum of rake scores across the six subsites divided by the maximum possible rake score (30) at each site, multiplied by 100 (0-100%). Percent cover, for emersed, rooted floating-leaved and free-floating lifeforms, represents the maximum % cover for each category [...]

Percent cover, for emersed, rooted floating-leaved and free-floating lifeforms, represents the maximum % cover for each category (0, 20, 40, 60, 80, 100%). These site level values were then applied to the entire pool using an inverse distance weighting interpolation method.

Managing for certain species and vegetation abundance/diversity, understanding where aquatic vegetation communities are stable and where changes are occurring, and identifying environmental factors associated with changes are important to managers and researchers on the Upper Mississippi River system.
