Indicators: Fish Assemblage
Fish assemblage refers to the variety and abundance of fish species in a given waterbody. Fish are sensitive indicators of physical and chemical habitat degradation, environmental contamination, migration barriers, and overall ecosystem productivity.
-
Indicators: Wetland Vegetation (Introduced Species)
Introduced plants are indicators of the ecological integrity of waters and evidence of increased human-caused disturbance in the watershed. Introduced species that cause economic or environmental harm, or harm to human health, are called invasive species.
-
Indicators: Wetland Vegetation (Plant Community)
Wetland vegetation specifically grows in water or is adapted to a growing in soil that is at least periodically flooded with water. These wetland plants are also referred to as “hydrophytes.”
-
Indicators: Chlorophyll a
Chlorophyll allows plants (including algae) to photosynthesize, i.e., use sunlight to convert simple molecules into organic compounds. Chlorophyll a is the predominant type of chlorophyll found in green plants and algae.
-
Indicators: Benthic Macroinvertebrates
Benthic (meaning “bottom-dwelling”) macroinvertebrates are small aquatic animals and the aquatic larval stages of insects. Benthic macroinvertebrates are commonly used as indicators of the biological condition of waterbodies.
