finding 8.5 : ecosystem-whole-system-management

Whole system management is often more effective than focusing on one species at a time, and can help reduce the harm to wildlife, natural assets, and human well-being that climate disruption might cause.



This finding is from chapter 8 of Climate Change Impacts in the United States: The Third National Climate Assessment.

Process for developing key messages: The key messages and supporting chapter text summarize extensive evidence documented in the Ecosystems Technical Input Report, Impacts of Climate Change on Biodiversity, Ecosystems, and Ecosystem Services: Technical Input to the 2013 National Climate Assessment.7406884d-2302-4644-aa50-12ed8baf4fd7 This foundational report evolved from a technical workshop held at the Gordon and Betty Moore Foundation in Palo Alto, CA, in January 2012 and attended by approximately 65 scientists. Technical inputs (127) on a wide range of topics related to ecosystems were also received and reviewed as part of the Federal Register Notice solicitation for public input.

New information and remaining uncertainties: Adaptation strategies to protect biodiversity include: 1) habitat manipulations, 2) conserving populations with higher genetic diversity or more plastic behaviors or morphologies, 3) changing seed sources for re-planting to introduce species or ecotypes that are better suited for future climates, 4) managed relocation (sometimes referred to as assisted migration) to help move species and populations from current locations to those areas expected to become more suitable in the future, and 5) ex-situ conservation such as seed banking and captive breeding.076ae54f-40da-494d-a736-a4ef99e2cff8 007a7014-723e-4ceb-a395-5c986b1bf884 0f6a0b9d-89f1-47d6-b508-5469c4134c43 32610191-4861-48b9-ab67-475b2c319d06 476c703b-59a2-49b1-9f58-06fe7d48afe1 Alternative approaches focus on identifying and protecting features that are important for biodiversity and are projected to be less altered by climate change. The idea is to conserve the physical conditions that contribute to high levels of biodiversity so that species and populations can find suitable areas in the future.181421a5-ba0c-495c-8982-0de79b79b654 87b2d33e-c89a-4924-b8f1-6f483b34d598 755532b1-d3a3-487f-8832-59e3ac8666f8 786410d9-a239-42cf-95b3-11e113b394e7

Assessment of confidence based on evidence: Given the evidence and remaining uncertainties, there is very high confidence that ecosystem-based management approaches are increasingly prevalent, and provide options for reducing the harm to biodiversity, ecosystems, and the services they provide to society. The effectiveness of these actions is much less certain, however.
