These established a definition of healthy urban watersheds; scientific principles and guidelines; a science-based watershed management approach; citywide watershed health goals and objectives for hydrology, physical habitat, water quality and biological communities; and strategies and actions for the next 2-5 years. The goals and objectives included both aquatic and terrestrial environments, but were aquatic-focused. Development of a Terrestrial Ecology Enhancement Strategy (TEES) was subsequently embarked upon in 2006. A multi-bureau city team coordinated the TEES work, with assistance from a technical advisory group--the Terrestrial Ecology Enhancement Strategy Advisory Group (TEESAG). The purpose of the TEES is to have a common body of information and agreed-upon priorities for conservation and restoration of terrestrial plant and animal species and habitats in Portland within a regional and state context. The TEES is designed to help achieve the watershed health goals and objectives in the Portland Watershed Management Plan. The main elements of the TEES include: • Identification of plant and animal species and terrestrial habitats needing protection, conservation, and/or restoration • Identification of key management issues • Articulation of watershed-specific objectives for terrestrial habitats and biological communities • Identification and implementation of priorities and actions for the next 2-5 years • Guidance to city bureaus and citizens for improving habitat and addressing plant and wildlife management issues • Selection of species and habitats to be monitored over time to determine the health of biological communities in Portland's urban watersheds This Summary and Update summarizes the TEES and provides updated information as of June 2011 for each of these elements. It also identifies future work that will help the City achieve its watershed goals and objectives. ______________________________________________________________________________ TEES Summary and Update June 28, 2011 iii SECTION 1 Background ____________________________________________________________ WHY DOES PORTLAND NEED A TERRESTRIAL ECOLOGY ENHANCEMENT STRATEGY? Portland’s City Council adopted the Portland Watershed Management Plan (PWMP) http://www.portlandonline.com/bes/index.cfm?c=38965 and its supporting scientific foundation document, the Framework for Integrated Management of Watershed Health (Framework) http://www.portlandonline.com/bes/fish/index.cfm?c=33528 in March 2006 (Resolution 36384). Together, these established a definition of healthy urban watersheds in Portland; scientific principles and guidelines; a science-based watershed management approach; citywide watershed health goals and objectives for hydrology, physical habitat, water quality, and biological communities; and strategies and actions for the next 2 to 5 years. Watershed Health Goals Hydrology—Move toward normative stream flows conditions to protect and improve watershed and stream health, channel functions, and public health and safety. Physical Habitat—Protect, enhance and restore aquatic and terrestrial habitat conditions and support key ecological functions and improved productivity, diversity, capacity, and distribution of native fish and wildlife populations and biological communities Water Quality—Protect and improve surface water and groundwater quality to protect public health and support native fish and wildlife populations and biological communities. Biological Communities—Protect, enhance, manage and restore native aquatic and terrestrial species and biological communities to improve and maintain biodiversity in Portland’s watersheds. Although the City’s watershed health goals include both the aquatic and the terrestrial environments, the objectives and actions in the PWMP are largely focused on the aquatic environment. The PWMP identified as a high priority the development and integration of a terrestrial component into watershed management. A Terrestrial Ecology Enhancement Strategy (TEES) was subsequently embarked upon in 2006. Work accomplished or underway was previously summarized in TEES Summary and Update documents dated August 2007 and ______________________________________________________________________________ TEES Summary and Update 1 June 2010. This June 2011 TEES Summary and Update presents the most recent information for the TEES and supersedes the August 2007 and June 2010 versions. The purpose of the TEES is to have a common body of information and agreed-upon priorities for conservation and restoration of terrestrial plant and animal species and habitats in Portland, within a regional and state context. The TEES is designed to help achieve the watershed health goals and objectives in the PWMP. The information assembled during the development of the TEES (see “Main Elements” below) is available to BES watershed teams to supplement existing watershed characterizations; inform the selection and prioritization of actions; add value to projects and other actions; determine monitoring priorities; and support and inform the Grey to Green (G2G) project.1 The TEES work also supports and informs an array of other City programs, plans, activities, projects, and decision-making processes, including the Portland Plan update, environmental regulatory improvement, parks and natural area management, and local bond share land acquisition. In addition, the TEES supports efforts of Metro (e.g., Nature in Neighborhoods, Intertwine and the Regional Conservation Strategy), the U.S. Fish and Wildlife Service, the Oregon Department of Fish and Wildlife (e.g., the Oregon Conservation Strategy), the Oregon Watershed Enhancement Board, and the Northwest Power and Conservation Council’s sub-basin planning. MAIN ELEMENTS The main elements of the TEES include: • Identification of plant and animal species and terrestrial habitats needing protection, conservation, and/or restoration (Special Status Species and Habitats) • Identification of key management issues (e.g., invasive species) • Articulation of watershed-specific objectives for terrestrial habitats and biological communities • Identification and implementation of priorities and actions for the next 2 to 5 years, as well as identification of long-term actions • Guidance to City bureaus and citizens for improving habitat and addressing plant and wildlife management issues • Selection of species and habitats to be monitored over time to determine the health of biological communities in Portland’s urban watersheds 1 Grey to Green is a 5-year effort that will complement ongoing BES implementation
