Lower Columbia River Estuary
Habitat Mapping Using Satellite Imagery, Hyperspectral Imagery, and Aerial
Videography
Type: Extent of
habitat (i.e., area of habitat and whether there has been a decline); condition
of habitat and sources affecting habitat (i.e., the condition or functionality
of the habitat); and stressors affecting habitat (i.e., which sources
have contributed to its degradation and whether they are direct or indirect
factors).
Category: Submerged, Intertidal, Wetland, and Upland
Cost: $130,000 for first phase; $300,000 needed to complete
Description: Estuary Partnership implemented an innovative project in
July 2000 to map and assess habitat using satellite imagery at 28m color and
5 and 15m black and white, hyperspectal imagery at 1.5 m, aerial videography,
and on the ground habitat surveys using volunteers. We completed the lower 46
river miles in 2000 and are now seeking funding to complete remaining 100 river
miles and analyze data. Products include: GIS maps of habitat types for whole
study area at much higher accuracy than previously available, landscape analysis
of entire study area, analysis of hyperspectral data at specific sites to characterize
habitat in great detail to look for connections to native species needs and
develop IBIs for habitat.
Outcome: The GIS maps and GIS habitat data will be used: a) to better
understand the relationship of juvenile salmonids to intertidal habitat; b)
to help identify and prioritize habitat conservation and restoration projects;
c) to help develop indicators of biological integrity; d) to do change analysis.
