However, it is suitable for use in annotating remotely sensed land types. nlcd2011 pasture/hay An area of a planet's surface which is partly covered by planted grasses, legumes, or mixtures of grass and legumes and used for livestock grazing or the production of seed or hay crops. 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. According to the NLCD 2011, at least 20% of these areas are covered by pasturelands or hayfields. Such thresholds - which are themselves fuzzy - are not strictly asserted in this definition. The NLCD also notes that the crops are grown on a perennial cycle in these areas. anthropised terrestrial environmental zone ranch
