Tundra landform and vegetation productivity trend maps for the Arctic Coastal Plain of northern Alaska
Arctic tundra landscapes are composed of a complex mosaic of patterned ground features, varying in soil moisture, vegetation composition, and surface hydrology over small spatial scales (10-100 m). The importance of microtopography and associated geomorphic landforms in influencing ecosystem structu...
