This map shows wetland and peatland type and extent for mountainous regions of central Peru. Multi-date, multi-sensor radar and optical imagery (Landsat TM/PALSAR/RADARSAT-1/SRTM DEM-TPI) combined with field validation were used to create the classified maps.
Agriculture/pasture - Land used for production of food or fiber (corn, potatoes, or other cropland); land use distinguishes agricultural land from similar natural ecosystem types (i.e., wetlands).
Barren - Land with limited ability to support life. Contains less than 33% vegetation cover. May include thinly dispersed scrubby vegetation. Includes bare rock, quarries, gravel pits, and transitional areas.
Developed - Areas where the manmade structures (buildings, towns, etc.) have >75% coverage. Primarily residential areas where manmade structures (i.e., buildings and farm equipment) are present, with less than or equal to 25% vegetation (trees, shrubs, and grass) interspersed.
Peatland - Poorly drained areas with >40 cm organic soil. Dominated by vascular plants with a cushion life form, with a smaller component dominated by mosses and graminoids.
Graminoid Wet Meadow - Poorly drained areas with <40 cm organic soil structurally dominated by graminoids.
Cushion Wet Meadow - Poorly drained areas with <40 cm organic soil dominated by a dense matrix of several species of Juncaceae, Asteraceae, and Plantaginaceae.
Shrubland - Nonwetland vegetation dominated by true shrubs, immature trees, or stunted growth trees/shrubs. Characterized by woody vegetation with a height <6 m.
Grassland - Nonwetland vegetation dominated by grasses.
Woodland - Nonwetland vegetation dominated by trees >6 m in height.
Water - Streams, canals, rivers, lakes, reservoirs, and impoundments. Areas persistently inundated by water that do not typically showannual drying out or vegetation growth at or above the water’s surface. Depth of water column is >2 m, such that light attenuation increases significantly and surface and subsurface aquatic vegetation persistence declines or is less detectable.
Snow - Land covered by snow
