Long Island Land Use and Land Cover
Science Center Objects
On Long Island, land use includes the human activities and management practices for which land is used. Land cover is a mosaic of developed, forest, agriculture, and wetlands areas. Both land use and land cover are usually discussed in similar environments. The National Land Cover Database (NLCD) serves as the definitive LANDSAT-based, 30-meter resolution, land cover database for the Nation. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. The National Land Cover Database
Dominant covers across Long Island are developed, open space and forests, with locally dense urban development. More than half (53 percent) of the land cover area across Long Island in 2006 was developed, open space, low and medium-intensity categories (figures 5 - 6). About 10 percent is developed, high intensity, and Kings County attributes to about 60 percent of this category area within its political boundaries. About 3 percent of Long Islands area is cultivated crops or agricultural (Homer and others, 2011; Fry and others, 2011).
From the early 1900's, land cover on Long Island has trended toward the conversion of open space and agricultural land into residential, industrial, and commercial development.
The accompanying web sites are available showing the use of land on Long Island and were compiled from reports prepared by the Nassau County Planning Department, the Suffolk County Planning Department, and the New York City Department of Planning. Data for the four counties on Long Island are not available for precisely the same time. Furthermore, the three agencies did not use precisely the same land classifications. Despite these inconsistencies, however, the data shown are reasonably representative for the period designated as present “2005-2010", and provide considerable insight to the general characteristics of land use on Long Island at the present time (2014).
