Aquatic vegetation in the Upper Mississippi River System (UMRS) provides food, spawning areas, and shelter to fish, wildlife, and invertebrates.
The objective of the LTRM element standardized monitoring is to accumulate data on the distribution, frequency of occurrence, and relative abundance of aquatic vegetation over a long period of time. The LTRM currently uses a stratified random sampling design in Pools 4, 8, and 13. In the past, other pools were sampled and other designs (e.g., transects and informal surveys) were used.
