11
Open Water - All areas of open water; typically 25 percent or greater cover of water (per pixel).
NLCD Land Cover Classification System Key - Rev. July 20, 1999
12
All areas characterized by year-long cover of ice and/or snow.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
21
Low Intensity Residential - Includes areas with a mixture of constructed materials and vegetation. Constructed materials account for 30-80 percent of the cover. Vegetation may account for 20 to 70 percent of the cover. These areas most commonly include single-family housing units. Population densities will be lower than in high intensity residential areas.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
22
High Intensity Residential - Includes highly developed areas where people reside in high numbers. Examples include apartment complexes and row houses. Vegetation accounts for less than 20 percent of the cover. Constructed materials account for 80 to 100 percent of the cover.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
23
Commercial/Industrial/Transportation - Includes infrastructure (e.g. roads, railroads, etc.) and all highly developed areas not classified as High Intensity Residential. Barren - Areas characterized by bare rock, gravel, sand, silt, clay, or other earthen material, with little or no "green" vegetation present regardless of its inherent ability to support life. Vegetation, if present, is more widely spaced and scrubby than that in the "green" vegetated categories; lichen cover may be extensive.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
31
Bare Rock/Sand/Clay - Prennially barren areas of bedrock, desert pavement, scarps, talus, slides, volcanic material, glacial debris, beaches, and other accumulations of earthen material.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
32
Quarries/Strip Mines/Gravel Pits - Areas of extractive mining activities with significant surface expression.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
33
Transitional - Areas of sparse vegetative cover (less than 25 percent of cover) that are dynamically changing from one land cover to another, often because of land use activities. Examples include forest clearcuts, a transition phase between forest and agricultural land, the temporary clearing of vegetation, and changes due to natural causes (e.g. fire, flood, etc.).
NLCD Land Cover Classification System Key - Rev. July 20, 1999
41
Deciduous Forest - Areas dominated by trees where 75 percent or more of the tree species shed foliage simultaneously in response to seasonal change.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
42
Evergreen Forest - Areas dominated by trees where 75 percent or more of the tree species maintain their leaves all year. Canopy is never without green foliage.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
43
Mixed Forest - Areas dominated by trees where neither deciduous nor evergreen species represent more than 75 percent of the cover present.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
51
Shrubland - Areas dominated by shrubs; shrub canopy accounts for 25-100 percent of the cover. Shrub cover is generally greater than 25 percent when tree cover is less than 25 percent. Shrub cover may be less than 25 percent in cases when the cover of other life forms (e.g. herbaceous or tree) is less than 25 percent and shrubs cover exceeds the cover of the other life forms. Non-natural Woody - Areas dominated by non-natural woody vegetation; non-natural woody vegetative canopy accounts for 25-100 percent of the cover. The non-natural woody classification is subject to the availability of sufficient ancillary data to differentiate non-natural woody vegetation from natural woody vegetation.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
61
Orchards/Vineyards/Other - Orchards, vineyards, and other areas planted or maintained for the production of fruits, nuts, berries, or ornamentals.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
71
Grasslands/Herbaceous - Areas dominated by upland grasses and forbs. In rare cases, herbaceous cover is less than 25 percent, but exceeds the combined cover of the woody species present. These areas are not subject to intensive management, but they are often utilized for grazing. Planted/Cultivated - Areas characterized by herbaceous vegetation that has been planted or is intensively managed for the production of food, feed, or fiber; or is maintained in developed settings for specific purposes. Herbaceous vegetation accounts for 75-100 percent of the cover.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
81
Pasture/Hay - Areas of grasses, legumes, or grass-legume mixtures planted for livestock grazing or the production of seed or hay crops.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
82
Row Crops - Areas used for the production of crops, such as corn, soybeans, vegetables, tobacco, and cotton.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
83
Small Grains - Areas used for the production of graminoid crops such as wheat, barley, oats, and rice.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
84
Fallow - Areas used for the production of crops that are temporarily barren or with sparse vegetative cover as a result of being tilled in a management practice that incorporates prescribed alternation between cropping and tillage.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
85
Urban/Recreational Grasses - Vegetation (primarily grasses) planted in developed settings for recreation, erosion control, or aesthetic purposes. Examples include parks, lawns, golf courses, airport grasses, and industrial site grasses.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
91
Woody Wetlands - Areas where forest or shrubland vegetation accounts for 25-100 percent of the cover and the soil or substrate is periodically saturated with or covered with water.
NLCD Land Cover Classification System Key - Rev. July 20, 1999
92
Emergent Herbaceous Wetlands - Areas where perennial herbaceous vegetation accounts for 75-100 percent of the cover and the soil or substrate is periodically saturated with or covered with water.
