Using multiple taxa and wetland classification schemes for enhanced detection of biological response signatures to human impairment

• A multi-taxa Index of Biological Integrity can increase sensitivity to disturbance. Using multiple wetland classes improves consistency. Mix and match approach monitoring cost-effectiveness. Wetland indices biological integrity (IBIs) are a common component in the water resources as required by United States’ Clean Water Act (CWA). The effectiveness an IBI monitor disturbance is dependent on metrics being consistently responsive measures human within described classification category. We present IBIs designed for two types commonly used systems – hydrogeomorphic (HGM) National Wetlands Inventory (NWI). making up were derived from anuran, avian, macroinvertebrate, vegetation communities; each representing increasing levels associated with gathering necessary data. Knowing which communities’ data best corresponds impairment maximize limited resources, especially if response differs based type NWI or HGM position landscape. By combining these schemes together, better define wetland’s form context landscape, more variability community explained impairment. Moreover, when taxa single scheme, gradient often sensitive than one-taxa group alone. This approach, combination taxa, hybrid 2-system schemes, creates additional utility measuring assessments and, restoration success.
