The map below shows legal Old Growth Management Areas (OGMAs) on Cortes Island. These mapping designations were determined by the Cortes Landscape Unit planning process and may or may not include actual old-growth forest. The Discovery Islands Forest Conservation Project will map old forest on Cortes Island using on-the-ground confirmation.
Non-legal OGMAs in parks and ecological reserves have also being mapped for Cortes Island and are used to meet the targets for OGMAs in the Cortes Landscape Unit. Those can be viewed here.
