Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
Adaptive management is "learning by doing" and adapting based on what is learned, in an objective, science-based management strategy that explicitly recognizes and delineates uncertainty.
Ecosystem services are attributes and outputs of ecosystems that are valued by human users. Ecosystem services are produced by ecosystem processes such as nutrient cycling, climate regulation, and maintenance of biodiversity. Ecosystems also provide marketable goods like seafood and timber.
Resilience is the ability of a system or a community to absorb shocks and still maintain the same basic structure and functions. Management for ecological resilience seeks flexible system behaviors that can deliver ecosystem goods and services on a sustained basis.
