* » Abstract |
This geodataabase provides an estimate to the spatial distribution of potential historical habitat for California Coastal Chinook Salmon, Central California Coast Coho Salmon, Northern California Steelhead and Central California Coast Steelhead. Intrinsic potential measures the potential for development of favorable habitat characteristics as a function of the underlying geomorphic and hydrological attributes, as determined through a Digital Elevation Model (DEM) and mean annual precipitation grid. The model does not predict the actual distribution of "good'' habitat, but rather the potential for that habitat to occur, nor does the model predict abundance or productivity. Additionally, the model does not predict current conditions, but rather those patterns expected under pristine conditions as related through the input data. Thus, IP provides a tool for examining the historical distribution of habitat among and within watersheds, a proxy for population size and structure, and a useful template for examining the consequences of recent anthropogenic activity at landscape scales. |
* Purpose |
Information on estimating the quality and extent of historical habitat is needed for ongoing efforts to conserve and eventually recover protected populations of Pacific salmonids. Because georeferenced spatial data on habitat and fish distribution at the regional scale are lacking, we adapted methods of the Coastal Landscape Analysis and Modeling Study (CLAMS) to implement a GIS approach in modeling the intrinsic potential (IP) of stream reaches to support juvenile steelhead, coho, and chinook salmon. The IP model uses geomorphic and hydrological attributes (expressed as the weighted geometric mean of indices for mean annual discharge, channel gradient, and channel constraint) to estimate the latent potential of stream reaches to provide favorable habitat characteristics for spawning and rearing. Indices for the model are derived from a 10 m DEM and PRISM precipitation data. Thus, the model predicts patterns of relative productive potential expected in the absence of human disturbances, as related through the input data. To apply the model appropriately in California, we investigated the species-specific weighting functions (proposed by CLAMS) for coho and steelhead using values available in the literature. Also, because patterns in precipitation and runoff vary across latitudes, we applied a linear regression model to gage station data to better estimate mean annual discharge from drainage area and precipitation.

» Description |
Calculating IP is a multi-step process that occurs both outside and inside a GIS. The first step creates a stream network from the Digital Elevation Model (DEM) and precipitation data that defines individual reaches and calculates values of gradient, valley floor width, and discharge for each. The second step creates suitability curves for these three variables based on life-history and habitat association of each species and life-stage. To construct a stream network, we implemented a model developed by Miller (2003 (Miller, D. 2003. Programs for DEM analysis)) that synthesizes grid-based data on topography derived from a 10 m resolution DEM and mean annual precipitation derived from the PRISM model (Daly et al., 1994). To run the model (Miller, 2003) (which is implemented outside of a GIS in a series of Fortran programs), we generated binary files of regional-scale elevation and precipitation grids. Beginning with these grids, we clipped the DEM and precipitation files to the watershed boundaries. The last input needed is a parameters file, and the only substantial change to the default inputs was to include regionally-specific equations relating precipitation to discharge. In the course of constructing the stream network, the model dynamically defines reaches on the order of 50-200 meters long, basing reach breaks on changes in gradient. In the resulting stream network, each reach is characterized by its gradient (averaged over the entire reach), valley width, and mean annual discharge (calculated at the downstream end of the reach). |
