Ecosystem Services/ EcoAssets Ecosystem Services: Products, Biodiversity, Habitat, & Sustainability in a Future with Climate Change

Ecosystem Services & Restoration

Chris has applied a range of technical and organizational methods to quantify and score a range of ecosystem services for forest, coastal, island, riverine, urban, pre-development, and targeted restoration sites. These have been applied at multiple spatial scales, including at the site, reach, watershed, regional and state levels, in the United States, Latin America and the Pacific Islands. Projects have ranged from watershed-level assessments of current and potential future wood (LWD) inputs and shade to stream systems (multiple watersheds in the Pacific Northwest), to broad-based ranking criteria for determining limiting factors and ecological assets for greenspace acquisition in the Portland Metropolitan Area. Much of his experience has involved quantifying ecosystem services, the projects below are specific examples of recent application for direct investment.

Select Project Experience

Granite Creek Watershed Assessment and Action Plan. Kalispel Tribe, Idaho/Washington & USDA Forest Service, Idaho Panhandle National Forest. Project duration: 7/2007 to 3/2009 (ongoing). Chris worked with a team to conduct a watershed assessment and action plan for bull trout and cutthroat trout restoration opportunities in a ~65,000 acre watershed near Priest Lake, Idaho. Chris provided a strategy for inventory, mapping, and enhancement prescriptions in riparian zones, specifically for ecosystem services (shade, LWD recruitment, nutrient inputs, etc) for the riparian zones on fisheries habitats.

Whychus Creek Stream Restoration. City of Sisters, Oregon/ Upper Deschutes Watershed Council. Project duration: 4/2008 to 6/2009 (Ongoing). Served as the riparian ecologist for a stream enhancement/ restoration project involving Whychus Creek, which flows through the City of Sisters, Oregon. Developed a matrix of current and potential future conditions meeting a 30% design criteria to enhance stream shade, bank stability, and other ecosystem services to meet water quality and fisheries enhancement goals. Analyzed fine-scale LiDAR imagery to identify geomorphic surfaces suitable for restoration or enhancement within the urban area, and prescribed specific treatments to enhance shade, LWD, floodplain conveyance, and bank stability options.

Portland Metro Greenways Assessment. Metro, Portland, Oregon. Project duration: 4/2007 to 5/2007. Chris served as project manager and landscape ecologist with a team to assess the potentials for aquatic resource conservation and enhancement prior to development and expansion of the Portland metropolitan area. Project outcomes included a prioritization matrix of ecological assets to rank areas in the Clackamas River Basin for aquatic species and habitats, riparian zone connectivity and forest health, invasive weed species, and stream channel diversity. Site-specific priorities were identified for potential acquisition/ valuation by Metro and resource enhancement.

Pacific Greenways Assessment. Friends of Forest Park, Portland, Oregon. Project duration: 4/2006 - 6/2006. Chris participated in a team to reassess the 1991 Pacific Greenway proposal to evaluate and ground truth the current conditions, and conduct a recreation and geographical (GIS) assessment along transportation routes from the Oregon Coast to Forest Park in Portland, Oregon. Specific tasks involved the evaluation of ecosystem services along each Greenway route, including forest and non-forest conditions, invasive and non-native plant species, wildlife habitat, and aquatic resources as they pertain to land ownership. Preliminary recommendations for habitat enhancement in the Greenways were provided as part of the analysis.
