has part adjacent to wetland area forested area scrubland area atmospheric boundary layer area of woody wetland 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 20% of these areas are covered by forest or shrubland vegetation. Such thresholds - which are themselves fuzzy - are not strictly asserted in this definition. NLCD:90 woody wetlands nlcd2011 An area of a planet's surface which is partly covered by forest or shrubland vegetation and where the underlying soil or substrate is periodically saturated with or covered by water. This area is in contact with an atmospheric column extending from the planetary boundary layer to the planet's exosphere with little to no physical obstruction.
