The Restoration Prioritization Framework was designed as a decision-making tool for the Lower Columbia River Estuary Partnership, to help identify the highest priority sites for restoration. This report describes the concept for developing the Tier 1 impact assessment, or 'disturbance scores' for the lower Columbia River floodplain. The 'Tier 1' terminology is no longer being applied in the greater Habitat Restoration Strategy, with the data set now referred to as simply the 'Landscape Disturbance' model. The GIS based data set was developed by the Battelle Pacific Northwest National

The research presented in this report is part of the regional habitat restoration program in the lower Columbia River and estuary (LCRE). As part of this program, we have established a suite of reference sites to help meet the goal of understanding and restoring wetland habitat. The data collected at these reference sites from 2005 through the present were analyzed in this study to meet two primary objectives: 1) to inform restoration planning and design by quantifying the ecological and hydrological conditions necessary for development of wetland plant communities and tidal channel networks
