This technical note was issued in 2008 to guide USDA NRCS staff when assessing hydrogeomorphic (HGM) wetlands. It provides an overview of original HGM concepts and supplies additional structure to the classification system. HGM classification is used in assessing changes to wetlands from proposed projects, wetland improvements, among others. Since its inception in 1993, HGM classification has been solely based on the geographic setting of the wetland in question. However, vegetation and soil properties may more strongly influence wetland function than geography. The USDA NRCS acknowledged this idea in this technical note and subsequently encouraged NRCS staff to include modifiers to original HGM classes to more accurately describe wetland characteristics.
