NetMap's Watershed Assessment
Watershed Attribute: Habitat potential for Chinook salmon (Oncorhynchus tshawytscha)
Data Types: Line (in channel).
Grid (raster)
Field Name: IP_species
Units: 0 - 1
NetMap Level 1 Module/Tool: Aquatic Habitats/ Create Aquatic Habitats
Model Description:
Parameter Description: A relative ranking of fish habitat quality for anadromous fish using preference curves and a geometric mean approach, based on Burnett et al. (2007). Published parameter values for coho (Oncorhynchus kisutch), steelhead (O. mykiss), and Chinook salmon (O. tshawytscha) are used.
NetMap's analysis tools (by subscription) can be used to modify the original model parameter values, add new watershed attributes or create new models including for different species, including resident fish (although NetMap contains models for westslope cutthroat and bull trout). Users may modify the preference curves or they may add other parameters such as confluence effects, substrate size, wood accumulation types and wood loading, among others. Models for Bull trout and cutthroat trout are also available in NetMap. Users may create their own habitat models and submit their preference curves for inclusion into NetMap tools, with appropriate reference to the develop(s).
Note that the model is applied to the definition of the fish-bearing network available by NOAA.
