April 1, 2015 - The Service announced today it is protecting the northern long-eared bat as a threatened species under the Endangered Species Act, primarily due to the threat posed by white-nose syndrome, a fungal disease that has devastated many bat populations. At the same time, the Service issued an interim 4(d) rule that eliminates unnecessary regulatory requirements for landowners, land managers, government agencies and others in the range of the northern long-eared bat.

The Service, states, federal agencies, tribes, conservation organizations and scientific institutions are working together as part of a national response team to address white-nose syndrome through disease monitoring and management, conservation and outreach.

March 20, 2015 - Today NOAA Fisheries and the U.S. Fish and Wildlife Service proposed reclassifying the green sea turtle under the Endangered Species Act.The proposal involves reclassifying green sea turtles into 11 Distinct Population Segments globally. This will ensure continued protections for all green sea turtles, while providing a more tailored approach for managers in addressing the specific threats that face each population. Following years of coordinated efforts in Florida and along the Pacific Coast in Mexico, nesting green sea turtle numbers have increased, leading to a recommended threatened status instead of endangered for those populations.

December 9, 2014 – The U.S. Fish and Wildlife Service today announced federal protection for the rufa subspecies of the red knot, a robin-sized shorebird, designating it as threatened under the Endangered Species Act. A "threatened" designation means a species is at risk of becoming endangered throughout all or a significant portion of its range.

"The red knot is a remarkable and resilient bird known to migrate thousands of miles a year from the Canadian Arctic to the southern tip of South America," said Service Director Dan Ashe. "Unfortunately, this hearty shorebird is no match for the widespread effects of emerging challenges like climate change and coastal development, coupled with the historic impacts of horseshoe crab overharvesting, which have sharply reduced its population in recent decades."

December 5, 2014 – Louisiana Department of Wildlife and Fisheries (LDWF) biologists have received a fifth cohort of juvenile whooping cranes at White Lake Wetlands Conservation Area (WCA) in Gueydan. The 14 young cranes received Dec. 4 add to the state's resident population established through an LDWF species restoration project.

"As we prepare to enter year five of this project, I encourage the public to continue to support our biologists in this effort by observing these birds from a distance and reporting any sightings of injured birds or anyone attempting to harm them in any way," said LDWF Secretary Robert Barham. "We are fortunate to have a number of private landowners who have assisted us by working with our staff when the cranes roost on their property and I thank them for their participation."

November 19, 2014 – In 1992, the U.S. Fish and Wildlife Service (USFWS) granted Ursus americanus luteolus (Louisiana black bear) threatened status under the U.S. Endangered Species Act of 1973, listing loss and fragmentation of habitat as the primary threats. A study was developed by the U.S. Geological Survey in cooperation with the University of Tennessee, the Louisiana Department of Wildlife and Fisheries, and the USFWS to estimate demographic rates and genetic structure of Louisiana black bear populations; evaluate relations between environmental and anthropogenic factors and demographic, genetic, and movement characteristics of Louisiana black bear populations; and develop data-driven stochastic population projection models to assess long-term persistence of individual subpopulations and the overall black bear population in Louisiana.

Data were collected with non-invasive DNA sampling, live capture, winter den visits, and radio monitoring from 2002 to 2012 in the four areas supporting breeding subpopulations in Louisiana: Tensas River Basin (TRB), Upper Atchafalaya River Basin (UARB), Lower Atchafalaya River Basin (LARB), and Three Rivers Complex (TRC). Bears were live trapped and radio collared in the TRB and TRC to estimate survival and reproductive rates, deterministic matrix models were used to estimate asymptotic growth rates, and stochastic population models were used to estimate long-term viability. DNA extracted from hair collected at baited, barbed-wire enclosures in the TRB, UARB, and LARB and capture-mark-recapture (CMR) analysis based on Bayesian hierarchical modeling methods were used to estimate apparent survival (φ), per capita recruitment (γ), abundance (N), realized growth rate (λ), and long-term viability.

October 22, 2014 in Natchitoches Parish, La. – Young cypress, oak and hickory trees will welcome tens of thousands of migrating waterfowl and song birds this fall as they rest at the Red River National Wildlife Refuge (NWR) near Shreveport during their annual migration. Thanks to a multi-year partnership between the U.S. Fish and Wildlife Service (USFWS) and The Conservation Fund, these critical lands along Refuge's Lower Cane River Unit have been protected and restored for the benefit of wildlife and nearby communities.

The recent transfer of 1,731 acres to USFWS caps a five-year effort to preserve nearly 4,500 acres at the Refuge. Red River NWR was established in 2000 with the goal of restoring the bottomlands associated with the Red River Valley in Louisiana to native hardwood forests, in support of over 40 species of mammals, 200 species of neotropical birds and over 14 species of waterfowl.

A Century Later, the Passenger Pigeon's Extinction Has Much to Teach Us

One hundred years ago – September 1, 1914 – the planet's last passenger pigeon died in captivity in a Cincinnati zoo. By some estimates, the species accounted for one quarter of all land birds in the hemisphere.

We've made enormous progress in conserving our native species and the habitat that supports them. But the passenger pigeon is no less extinct. And for all eternity, the North American landscape will never be the same.

For millennia before European settlement, billions of passenger pigeons filled the skies of North America. Eyewitnesses described migrating flocks that stretched a mile wide, darkening the sky for days with their grayish-brown bodies as they flew overhead.

Great News - Identification of the Host Fish for A Threatened Freshwater Mussel Species in Louisiana!

Tony Brady from the Natchitoches National Fish Hatchery (NNFH) has identified the host fish, or shall we say fishes, for the federally threatened Louisiana pearlshell mussel! In collaboration with personnel from the Louisiana Ecological Services Office (LESO), the US Forest Service, the University of New Orleans (UNO) and the Louisiana Department of Wildlife and Fisheries (LDWF) -Natural Heritage Program, Tony has finally answered the 23-year-old host fish question, first posed in the 1990 Louisiana Pearlshell Mussel Recovery Plan. Since 2011, Tony has been infesting potential host fish species with larval mussels (glochidia) from Louisiana pearlshell females at the NNFH. In partnership with LDWF's Hatcheries Department, he moved the host fish trials to the state-owned Booker Fowler Fish Hatchery in 2014 because the hatchery's water source closely matches that of the mussel's home streams. In March 2014, Tony and personnel from the LESO and UNO gathered potential host fish from Louisiana pearlshell mussel streams and transported them to Booker Fowler, where fish were separated into tanks by species and cared for by hatchery staff. Later that month, Tony returned to the streams and collected four gravid Louisiana pearlshell mussels, which were held for four days at Booker Fowler until the mussels naturally released their glochidia. The glochidia were then used to infest 13 different fish species, and the adult mussels were returned to their natural streams. In April 2014, success was realized when the newly metamorphosed Louisiana pearlshell mussels (transformers) dropped off their host fishes and were collected from the tanks! In this study, the redspot darter was found to be the primary host fish for the species. Redfin shiners, striped shiners, creek chubsuckers, and bluegill and long-ear sunfish all served as successful secondary host fishes for the Louisiana pearlshell mussel. In discovering this information, we have met an important recovery goal that will allow for the pursuit and realization of future recovery goals that are contingent upon knowing the host fish species. Thanks to the successful research and collaboration among many partners, we are truly making great strides in the recovery of the threatened Louisiana pearlshell mussel!

July 17, 2014 - The U.S Fish and Wildlife Service announces a draft policy on crediting voluntary conservation actions taken for species prior to their listing under the Endangered Species Act. The proposed policy seeks to give landowners, government agencies, and others incentives to carry out voluntary conservation actions for nonlisted species by allowing the benefits to the species from a voluntary conservation action undertaken prior to listing under the Act to be used – either by the person who undertook such action or by a third party – to mitigate or to serve as a compensatory measure for the detrimental effects of another action undertaken after listing. This policy will help us further our efforts to protect native species and conserve the ecosystems on which they depend.
