Looking Back: Spotlight on Rudolph Dieffenbach

On Sunday we started a regular feature to highlight the insanely interesting, but little known, history of your National Wildlife Refuge System. The first post was dedicated to Rudolph Dieffenbach, a man who acquired more land for American wildlife than any other figure before or after his era.

North Dakota: Climate and Disease Take Toll on American White Pelicans

Each April and May, in a rite of spring, American white pelicans begin arriving in their Northern Plains breeding grounds from the Gulf of Mexico.  But for the last several decades, something has put the large birds ahead of schedule.  That something, researchers believe, is warming tied to climate change—and it's contributing to more deaths of pelican chicks from severe spring storms.

Rhode Island: Refuges Go Green for a Brighter Future

Rhode Island national wildlife refuges are working toward a brighter future by conserving energy and reducing their carbon footprint through use of alternative energy sources, natural lighting and recycled materials.

Kansas: Climate-Savvy Restoration Project Makes Wildlife Feel At Home

In the state popularized by the film “The Wizard of Oz,” conservation partners aren’t just dreaming about a better world over the rainbow. They’re joining forces to fight climate change and provide a home for wildlife – now and into the future.

Arkansas: Warming Trends Changing the Hunt for Waterfowl

Researchers have quantified what many hunters already knew: fewer ducks are spending the winter in Arkansas and four other Southeastern states. A 50-year analysis of duck data shows warmer temperatures are a key factor in the change.

New York: Invasive Insect Infestations Spread Further North, Threatening Hemlock Forests

As temperatures warm, infestations of hemlock wooly adelgid are spreading north into New York and New England. The invasive insects introduced from Japan can destroy a hemlock stand in just a few years. Hemlock stands often provide shade keeping streams cool enough for brook trout and other fish.  

This week's climate change stories took us all the way from the Colorado River basin to the deciduous forests of Michigan.  Below, you'll find links to each story, so check them out, leave a comment, and share them with your friends!

Utah: Managing Water Resources for Fish, Wildlife and People 
In the face of a warming climate and persistent drought, people and wildlife along the Colorado River and its tributaries in Utah and other Upper Colorado River basin states are benefiting from cooperative efforts to recover four species of endangered fishes while effectively managing water for human uses.

Georgia: ‘Wonder Tree’ Stands Tall in a Changing Climate
Federal biologist Laurie Fenwood calls the longleaf pine “the wonder tree,” because of its versatility and ability to survive in a variety of extreme conditions, ranging from strong winds to beetle infestation. The longleaf may also have the ability to serve as the centerpiece of carbon sequestration efforts in the Southeast. These characteristics make the longleaf pine well-suited for a changing climate.

Hawaii: Saving 'Rainforests of the Ocean' 
Tropical coral reefs are among the world’s most diverse ecosystems, harboring thousands of species in a complex community built by living corals. But in the Hawaiian and Pacific Islands, as elsewhere, these ecosystems are declining because of human impacts, including climate change.

Virginia: Rising to the Challenge at Chincoteague 
Chincoteague National Wildlife Refuge has been designated a Globally Important Bird Area and one of the top ten birding hotspots by the National Audubon Society. But this idyllic location faces profound threats from sea-level rise associated with a warming climate.

Michigan: A National Emblem Faces Change 
Scientists have determined bald eagles along Michigan’s shorelines and rivers are gradually beginning to nest earlier each season. More than a half-century of bald eagle research in Michigan has brought this trend to light, a potential indication of this iconic species’ response to changes in climate in the upper Midwest. 

Welcome back to another weekly round up of stories from our ongoing series on climate change. From the endangered roseate tern of the North Atlantic coast to the voracious South American plant eating rodent called the nutria, the topics covered in this week's stories have been as diverse as the potential impacts of climate change on fish, wildlife, and habitat.  Below, you'll find summaries, pictures, and links from all those stories.

As usual, thanks for your support, please feel free to leave us a comment to tell us what you think!

Connecticut: Shoring Up a Disappearing Island for Endangered Roseate Terns

The roseate tern is a federally endangered seabird whose favored nesting areas are found on rocky offshore islands and barrier beaches along the north Atlantic coast. The tern is losing some of its prime seacoast habitat because of erosion that may be compounded by climate change.

Oklahoma: Warmer Stream Temperatures Could Test Rare Water Species

Water pollution, agriculture runoff and the construction of dams and reservoirs have already shrunken habitat for rare fish and mussel species in Oklahoma. A historic drought is compounding the problem. And now, biologists speculate the fish and mussels could face another potential stressor: rising stream temperatures as a result of climate change.

Tennessee: Brook Trout Feeling the Heat 

Changes in water temperature and the unpredictability of a changing climate are complicating already challenging efforts to restore and rebuild populations of Southern Appalachian brook trout across East Tennessee and its southern range. The U.S. Fish and Wildlife Service is working with its partners in the Eastern Brook Trout Joint Venture to change that and develop the science needed to restore populations of brook trout and strengthen their long-term sustainability in cold-water fisheries so popular among anglers.

South Dakota: No Ducking Climate Change Impacts to Wetlands

The mallard feeding at the local park; the flock of northern shovelers passing overhead; and the nesting pair of blue-winged teal – all common wetland birds – depend on the rich habitat of North America’s wetlands. Learn how climate change is affecting wetlands in South Dakota and the Prairie Pothole Region and how can new climate models help resource managers understand and respond to these changes.

Maryland: Restoring Native Forests Helps Animals Adapt at Blackwater National Wildlife Refuge

Blackwater National Wildlife Refuge is the first national wildlife refuge in the nation to develop a comprehensive strategy to adapt to sea-level rise before it is too late.

Another week, another round of climate change stories from across the country as our series continues. Please share this link with your friends and tell us what you think!

Vermont: Bicknell’s Thrush Faces Multiple Climate Change Threats

Vermont's mountain peaks are like a chain of islands separated by a sea of unsuitable habitat for the Bicknell's thrush. As the climate warms, the state's high elevation evergreen forests are shrinking. The thrush also faces the probability of migrating north after their food supply peaks and the additional danger of more hungry red squirrels raiding their nests.

Indiana: Climate Change Raises Stakes in Efforts to Conserve Endangered Indiana Bat 

Midwest bat populations already faced serious threats, such as the loss of habitat to development, when they were struck three years ago by a deadly disease known as white-nose syndrome. The disease is still killing bats, the endangered Indiana bat among them. Scientists fear climate change could add to stressors on the imperiled species.

Nevada: Climate Change May Impact Existing Refuge Water Concerns 

In southwestern Nevada, the nation’s need for renewable energy converges with climate change and a national wildlife refuge’s efforts to fulfill its mission.

Oregon: Preparing for Change on the North Pacific Coast 

Coastal and marine environments in Oregon and throughout the North Pacific region are rich in natural wealth, scenic beauty and quality of life. They are also among the first places where the effects of climate change and other environmental stressors have begun and will persist in coming decades.

Florida: Climate Change and the People Factor 

As biologists and conservationists start to grapple with safeguarding wildlife in the face of accelerating climate change, they’ll need more than a few computer models and forecasts.
