Lower Columbia Estuary Partnership

Change in land cover over roughly the past 140 years was evaluated for the Lower Columbia River and Estuary by comparing digital GIS representations of late 1800’s maps (Office of Coast topographic sheets, and General Land Office survey maps) with recent land cover data that was generated by the Lower Columbia Estuary Partnership as part of the Columbia River Estuary Ecosystem Classification. The evaluation was conducted for the historical floodplain of the tidally influenced, lower 146 miles of river.
