overlaps adjacent to atmospheric boundary layer mixed forest area of mixed forest NLCD:43 nlcd2011 An area of a planet's surface which is primarily covered by a forest in which the trees are a mixture between those that lose and retain their foliage despite seasonal change. The surfaces of this area (including the surface of the forest canopy) are 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, areas of mixed forest are dominated by trees generally greater than 5 meters tall, and making up more than 20% of total vegetation cover. The NLCD 2011 continues to state that neither deciduous or evergreen trees make up more than 75% of the total tree cover. Such thresholds - which are themselves fuzzy - are not asserted in this definition. vegetated area
