The extent and types of wetlands in the study areas are discussed and mapped based on existing literature, aerial photography, and extensive field work. The wetlands study builds on information from other chapters in the Pebble EBD, including soils (chapter 5), surface water hydrology (chapter 9) and vegetation (chapter 13).


  • Scientists gathered data at 16,947 sites, recording information on vegetation, soils and hydrology at each location.
