Olympic Peninsula Regional Anadromous Fish Habitat Intrinsic Potential Modeling

Mapping and Documentation Portals

As stated on ONRC's main page, TerrainWorks, the architects of NetMap, the software we have been using the last four years, has issued this advisory relating to an overestimate of high IP scores. As a consequence, all maps relating to earlier IP modeling work have been removed. Please note however that all the documentation and references have been retained and are still available at the sidebar to the left. Below is a summary of the sidebar links.

Previous IP Modeling Work

In 2012 and 2013, ONRC had partnered with Wild Salmon Center to implement IP modeling for the three species in four basins* of varying sizes:

Work on developing viable IP models for the Outer Washington Coast (OWC) has involved several steps. Phase I, which involved IP modeling using default parameters supplied with NetMap watershed modeling software, was completed. Phase I NetMap models were implemented in the above basins for Chinook, Coho, and Steelhead.

IP Peer Review Workshop, October 31, 2012

Following the implementation of Phase I, a workshop to gather OWC experts in fish biology, hydrology, GIS, and other fields was organized and took place on October 31, 2012. Workshop information, packets, and presentations are available here.

The purpose of the workshop was to open a dialogue across the various disciplines to accomplish these goals:

Addressing the first two goals, a primer on just what Habitat Intrinsic Potential modeling is and how it is done in NetMap is provided in this presentation.

Following introductions and the presentation above, participants were divided into two groups, a Map Review Group and Habitat Suitability Values Group. Each group received worksheets and questionnaires which were used to collate responses and to guide discussions of the last three goals.

Discussion: IP Binning / Symbolization

Binning refers to the classification of ranges of IP scores into categories, called "bins" and is a method of symbolizing habitat quality on a map. During Phase I mapping of IP scores, a six bin scheme was used as no viable relationship exists yet between IP scores and what is on the ground along the OWC in terms of habitat quality.

Workshop discussions lead to a consensus on two important points:

A much more extensive discussion is available here.

Following the compilation of participant responses at the IP Review Workshop, new models were constructed in consultation with Mindi Sheer at NOAA.

Partnerships

The Habitat Intrinsic Potential Modeling project has now become a mature, in-process Olympic Peninsula wide effort. In addition to the Wild Salmon Center (WSC) and Washington Coast Sustainable Salmon Parnership (WCSSP), the Washington Department of Natural Resources (WaDNR) has joined the effort to implement and improve IP modeling in the region.

Reports

Two reports with extensive information on the work done prior to 2015 were generated. The first, the "Phase I Report June 2012" documents the work done prior to the IP Peer Review Workshop, October 31, 2012 which was attended by more than 30 particpants. The phase II models and mapping efforts follwing this workshop are detailed in the "Phase II Report FEBRUARY 2013".

These two reports, together with the information and documents provided above, provide a wealth of data and metadata relating to the current effort just completed.

Current Status

WRIA 19 has been added to the previously modeled WRIAs* on the Outer Washington Coast expanding the modeling area to the entire Olympic Peninsula not including Puget Sound waters under study elsewhere:

*Basins are equivalent to watersheds, Level 6, or 6th Field Hydrologic Units; the NRCS HUC12 units are equivalent to subwatershed, Level 7, or 7th Field Hydrologic Units. WRIAs, or Water Resource Inventory Areas, can be considered approximately a Level 5, or 5th Field Hydrologic unit.

As a mature project, the focus has narrowed to three salmonid species: Chinook, Coho, and Steelhead. There are seven models, three provided by default with TerrainWorks' NetMap software, and four provided by ONRC and WSC.

The WSC | ONRC 2012 models are a product of earlier IP modeling efforts (see 'PHASE I MODELS' link on the sidebar to the left) and subsequent review from fish biologists, local experts, and other stakeholders. The review documentation is available at the 'IP REVIEW RESULTS / DOCUMENTS' link on the sidebar to the left.

The latest documentation for Burnett, 2007 Coho and Steelhead; Busch, 2011 Chinook, and the WSC | ONRC 2012 (Chinook, two Coho, and Steelhead) models is available at the 'PHASE II MODELS' link on the sidebar to the left as well.
