Statement of the problem Podostemum ceratophyllum, is an important aquatic plant that is diminishing in natural habitats (Wood et al., 2017). P. ceratophyllum, is a key habitat for Darters as well as being part of the diet for various crayfish and macrophytes. The crayfish as well as other macroinvertebrates offer a foundational role in ecology. One of the greatest threats to P. ceratophyllum is sediment. Sediment suffocates the plant. An important but missing part of studies could be erosion occurring upstream from habits. This is where historical climate data could be applied along with satellite photos that may indicate erosion. The crayfish and other macrophytes still offer many opportunities for investigation. The crayfish as well as other macroinvertebrates offer a foundational role in ecology. Not much academic research has employed the use of GIS and crayfish habitat.
