adjacent to adjacent to grassland area atmospheric boundary layer area of gramanoid or herbaceous vegetation NLCD:71 grassland/herbaceous According to the NLCD 2011, at least 80% of these areas are covered by grasslands or non-woody, herbaceous plants. Such thresholds - which are themselves fuzzy - are not strictly asserted in this definition. The NLCD description also notes that, while no "intensive" management such as tilling is performed in these areas, they may be used for grazing. 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. nlcd2011
