Salmon Habitat Restoration Planning (SHaRP) Model
January 28, 2021
The Salmon Habitat Restoration Planning (SHaRP) model is a process-based analysis for quantifying historical, current, and future habitat conditions, and modeling the potential benefit of alternative restoration actions to salmon populations.
To assist aquatic habitat restoration planning for salmon populations in the Pacific Northwest, we developed the Salmon Habitat Restoration Planning (SHaRP) model. The SHaRP model consists of three separate modules: the spatial analysis, the habitat analysis, and the life-cycle models.
- The spatial analysis includes the GIS processes and analyses that translate raw data layers into estimates of historical and current habitat areas and quality for each reach in the basin.
- The habitat analysis then takes those data and additional information to estimate life- stage capacities and productivities for each species in historical, current, and future habitat scenarios.
- The salmon life cycle models use the habitat scenarios to evaluate which types of habitat change most influence spawner abundance, and to identify which types of habitat restoration are most likely to aid salmon recovery.
Chehalis River Basin Application
In the Chehalis River basin, we analyzed the effects of changing eight drivers of habitat change: migration barriers, fine sediment, wood abundance, riparian shade, channel straightening, bank armor, beaver ponds, and floodplain habitats, and modeled effects of those changes on spawner abundance of coho salmon, Chinook salmon, and steelhead.
