Index watershed integrity
Index of Watershed Integrity for the conterminous United States showing higher integrity in bluer colors, moderate integrity in yellows, and lower integrity in redder colors. Because watersheds of consecutive stream segments are nested and overlap, each value is mapped onto the most downstream catchment within each watershed. Index of Biotic Integrity (IBI) Contents Introduction Determining an IBI score Exploring the value of IBI to NRCS The Index of Biotic Integrity (IBI) is a well-known indexing procedure commonly used by academia, agencies, and groups to assess watershed condition. This index has been used in throughout the United Environmental Integrity Index. The EII is a program designed to continuously monitor and assess the chemical, biological, and physical integrity of Austin’s creeks and streams. Currently, all watersheds are monitored on a two-year rotating basis. Data available for mapping and download include a multimetric stream health index for sampled reaches derived from fish, macroinvertebrate, instream habitat and geomorphic measures. Also available is a watershed integrity score for each subwatershed in Virginia derived from a multimetric index of biotic integrity. An advantage of this approach is that the index can be readily deconstructed to identify factors influencing index scores, thereby directly supporting the strategic adaptive management of individual components that contribute to watershed integrity.
across the United States were used to evaluate the performance of a national level Index of Watershed Integrity (IWI) at regional and local watershed scales.
It also means that in many watersheds acid mine drainage is a persistent pollution source of surface water bodies.
