part of adjacent to wetland area atmospheric boundary layer area of emergent herbaceous wetland nlcd2011 NLCD:95 This class is in need of refinement, particularly in linking to other entities in the ontology. However, it is suitable for use in annotating remotely sensed land types. According to the NLCD 2011, at least 80% of these areas are covered by herbaceous vegetation. Such thresholds - which are themselves fuzzy - are not strictly asserted in this definition. emergent herbaceous wetlands An area of a planet's surface which is primarily covered by perennial herbaceous vegetation and where the underlying soil or substrate is periodically saturated with or covered by water.
