Washington, DC– U.S. Sens. Jeff Flake (R-Ariz.) and John McCain (R-Ariz.) today introduced the Mexican Gray Wolf Recovery Plan Act to direct the U.S. Fish and Wildlife Service (USFWS) to publish the first revised recovery plan for the Mexican gray wolf in Arizona and New Mexico in 34 years. As a result of the 1982 Mexican Gray Wolf Recovery Plan, an experimental population of wolves were placed in Arizona and New Mexico and since that time, land owners and public officials have voiced concern about the program.
This legislation would require that the USFWS work with state and local entities to ensure they have input in the drafting of a new recovery plan. In addition, if the USFWS does not comply with the plan, then Arizona and New Mexico are able to supplement or assume management of the recovery process. This bill also includes a provision that would require automatic delisting of the Mexican gray wolf as an endangered species once conservation goals have been reached.
VALLEJO, California – With tree mortality rising to an estimated record-high 27.6 million trees in California in 2015, the U.S. Forest Service Aerial Survey team’s role in generating data for the agency and state and local partners is more critical than ever.
The U.S. Forest Service began doing aerial survey detection in the Pacific Northwest Region in the 1950s, with a small program in the Pacific Southwest Region (California) established in the 1990s. A dedicated team was assigned to the regional office in the early 2000s when Sudden Oak Death became more prevalent. In addition to detecting the Sudden Oak Death and conifer mortality, aerial survey flights first detected the Gold Spotted Oak Borer infestation in 2004.
April 6, 2016. Moss growing on urban trees is a useful bio-indicator of cadmium air pollution in Portland, Oregon, a U.S. Forest Service Pacific Northwest Research Station-led study has found. The work - the first to use moss to generate a rigorous and detailed map of air pollution in a U.S. city - is published online in the journal Science of the Total Environment.
"What's unique about this study is that we used moss to track down previously unknown pollution sources in a complex urban environment with many possible sources," said Sarah Jovan, a research lichenologist at the station based in Portland and one of the study's co-leads.
Moss have been used as bioindicators - living organisms that can help monitor environmental health - by the Forest Service and other agencies for decades. Because moss lack roots, they absorb all of their water and nutrients from the atmosphere, inadvertently taking up and storing whatever compounds happen to be in the air.
Sacramento, Calif. – Methane emissions from restored wetlands may offset the benefits of carbon sequestration a new study from the U.S. Geological Survey suggests. Wetlands are known to reduce atmospheric carbon dioxide through plant photosynthesis and also provide habitat and food sources for wildlife, act as biological filters for improving water quality and improve coastal protection in the face of sea level rise. What is not well understood is how wetland production of other more potent greenhouses gases like methane offset these benefits. Results from the new study show that restored wetlands can release enough methane to reduce or even negate the benefits the same wetlands offer of carbon sequestration.
Six new sets of maps from USGS reveal the diverse and complex range of seafloor habitats along 130 kilometers (80 miles) of the central California coast from the Monterey Peninsula north to Pigeon Point. The publicly available maps can be used by a large stakeholder community to understand and manage California’s vast and valuable marine resources.

The U.S. Department of the Interior, U.S. Department of Commerce, PacificCorp, and the states of Oregon and California today State and federal officials also signed a new, separate agreement with irrigation interests and other parties known as the 2016 Klamath Power and Facilities Agreement (KPFA). This agreement will help Klamath Basin irrigators avoid potentially adverse financial and regulatory impacts associated with the return of fish runs to the Upper Klamath Basin, which are anticipated after dams are removed.
