Summary
Located across southern Oregon and northern California, the Klamath Basin consists of unique ecological areas and natural resources that provide important ecosystem services to the region. Climate change impacts, such as warmer air temperatures and decreases in water levels, are likely to significantly affect natural systems and resources of the Klamath Basin. The National Center for Conservation Science and Policy (now the Geos Institute), in collaboration with the University of Oregon’s Climate Leadership Initiative (CLI), led a series of workshops assessing the likely risks posed by climate change to human and natural systems in the Klamath Basin and recommended strategies to increase the capacity of these systems to resist and adapt to change.
Background
The Klamath Basin (Basin) encompasses three counties in southern Oregon and five counties in northern California. The Basin drains approximately 15,571 square miles and includes Upper Klamath Lake and the Klamath River; nineteen large dams within the Basin provide hydropower, water storage, and irrigation diversions in the region. The Upper Klamath Basin, which lies upstream of Keno, Oregon, is predominantly a high desert ecosystem, while the Lower Basin is predominately made up of temperate rainforests and mixed conifer forests. Both the upper and lower basins support a wide variety of animal and plant species, including several unique and relict species. Agriculture (~20%) and forestry (~75%) dominate the Upper and Lower Basin, and at least seven Native American tribes depend on natural resources within Klamath Basin. Climate change impacts including warmer air temperature, drier summers, and decreases in soil moisture and water levels in lakes and rivers are likely to significantly affect the natural systems and resources of the Klamath Basin.
The Geos Institute and the CLI facilitated a process intended to advance the development of basin-wide planning for the risks and impacts associated with climate change. Their process helps local stakeholders assess regional climate change projections, identify likely impacts, and recommend strategies to prepare for and build resilience to potential impacts. In the Klamath Basin, the Geos Institute and CLI held a series of workshops with local stakeholders to identify probable climate change impacts to the natural, built, economic, human, and tribal systems of Klamath Basin. Local experts, leaders, and stakeholders developed a suite of strategies to prepare communities and natural resources for those changes.
Implementation
The MAPSS Team at the USDA Forest Service Pacific Northwest Research Station downscaled model projections for temperature, precipitation, vegetation, wildfire, and other variables to locally-relevant scales. This data was then mapped and analyzed by scientists at the Geos Institute. The Geos Institute and the CLI presented these climate projections to local leaders and experts to assess the likely impacts of climate change on natural systems (aquatic and terrestrial species and habitats), built (infrastructure), economic (agriculture, forestry, business), human (health, education, emergency services), and tribal systems. Finally, recommendations were made for how to prepare for the impacts expected under climate change. The strategies and actions suggested are likely to increase the resistance and resilience of natural resources and local communities to climate change.
Outcomes and Conclusions
A number of strategies were recommended to prepare the natural, built, economic, human, and tribal systems for the impacts of climate change. These strategies are covered in detail in the report Preparing for Climate Change in the Klamath Basin. Climate change preparation recommendations for natural systems focused on:
- Aquatic (water quality and quantity, sediment, shifting stream flow patterns, groundwater-fed springs, habitat and species resiliency)
- Terrestrial (range shifts, noxious and invasive plants, riparian areas, species loss, conservation priorities, forest management objectives, public education, economic analysis of the value of the Basin’s ecosystem services)
Climate change preparation recommendations for human systems focused on:
- Built (water, power, roads, rail, homes and building design)
- Economic (economic health, agriculture, forestry, recreation and tourism, commercial and subsistence fishing, health care industry, education)
- Human (shifts in human population, public health, social services, emergency management, vulnerable populations, public safety)
- Tribal (communication, carbon credits and cap and trade, incentives, burning, traditional ecological knowledge)
The results of the workshops and final report are intended as a starting point for addressing climate change impacts in the Klamath Basin. Stakeholders and sectors across the Basin should work together to develop a regional, multi-sector climate preparation framework and strategies for implementation. Actions should focus on building resiliency and resistance to climate change.
This project is part of a larger initiative aimed at developing integrated climate preparation plans and policies for the Upper Willamette, Rogue River and Umatilla Basins. A common theme identified by all groups was the need for integrated, co-beneficial climate preparation plans and policies.
