The module focuses on the Hydric Soil Technical Standard. The Hydric Soil Technical Standard (HSTS) provides a quantitative method of determining if a soil meets the definition of a hydric soil. The HSTS can be used to: 1) Identify a soils forming as hydric soils when a field indicator may not be present (e.g. wetland creation sites, problematic hydric soils); 2) Evaluate the current functional status of a hydric soil (e.g. change to hydrology); and 3) Propose changes to hydric soil indicators (e.g. expanding jurisdictional extent of an indicator, revising an existing indicator, adding a newly developed indicator). The HSTS requires quantitative measurements showing the soil becomes saturated and anaerobic in the upper part during normal precipitation years.
Target audience: Wetland field practitioners who need expertise in hydric soils and seek to understand how hydric soils are formed and how to recognize and interpret the information they provide when observed in the field.
