Sixth-Graders Learn About Migratory Birds’ ‘Superpowers’ at Salton Sea

Joanna Gilkeson, External Affairs, Pacific Southwest Region, tells us about a sixth-grade trip to Sonny Bono Salton Sea National Wildlife Refuge.

Surrounded by desert, mountains and farm fields, Sonny Bono Salton Sea National Wildlife Refuge is a much-welcomed oasis for migratory birds passing through the heart of southeastern California. In November, the refuge hosted nearly 100 Sixth-Graders to celebrate the 100-year anniversary of the Migratory Bird Treaty (MBT).

Felicia Sirchia and Peter Sanzenbacher, Service biologists, are passionate about connecting young people with the outdoors. The two led the charge to invite the local sixth-graders to the refuge, many of whom had never visited the area, despite its proximity to their community. “Many of these students are underserved when it comes to experiencing nature. We wanted to teach them tangible outdoor skills – how to use binoculars and scopes and how to identify migratory birds,” says Sanzenbacher.

The day began with discussions about bird migration and the everyday challenges birds face, warming the students up to the idea of wildlife. The sixth-graders participated in an interactive game where they “transformed” into birds so they could learn about and experience the different challenges migratory birds face along their long journeys, including predators and storms. Then the students learned about the “superpowers” of migratory birds, those special physical and behavioral adaptations that allow them to migrate great distances between their breeding and overwintering areas.

The sixth-graders were finally introduced to the basics of bird identification, both sight and sound, and learned how to use binoculars and scopes to test out their new skills and identify the spectacular birds of the Salton Sea. “Over the course of the day, we saw the students become more confident in their birding abilities, and seek out the awesome diversity of wildlife in their backyard,” Sirchia says. “It was great to see the students become empowered.”

Chris Schoneman, project leader at the refuge, believes that this event can be expanded upon. “It was a terrific example of how we can provide our communities with an even better nature experience when we combine our talents within FWS and our volunteers and refuge Friends groups. Even though the MBT Centennial was the celebration this year, we hope to continue this experience with our local schools into future years."

Thanks to the staff, volunteers and Friends who helped make the event possible. And thanks to the sixth-graders and teachers of Bill E. Young Middle School in Calipatria, California, for their energy and enthusiasm.

A Nose Ring Helps Researchers Studying Importance of Wetlands

Visitors to Red Rock Lakes National Wildlife Refuge may be treated to a rather strange sight during future visits: a duck with a nose ring.

Say what?

That’s right. Researchers are conducting a long-term demographic study of female lesser scaup at the refuge, which supports one of the highest recorded densities of nesting lesser scaup in North America.

The nasal marker, applied in 2011, allows the duck to be easily identified at a distance if she returns to the study site, providing researchers with valuable survival data.

Why go to all this trouble, you might ask?

Across the 11 states of the arid Intermountain West, wetlands are very scarce resources, comprising less than 2 percent of the total area. And nearly 90 percent of wetlands in the region occur on just 10 percent of the land area. If you are a duck in search of water, pickings are slim and far apart.

Researchers know that this female and other ducks across the region need wetland connections. But what this study revealed is the critical importance of female pre-breeding body condition on if, and when, she nests. The earlier she can nest, the more likely she is to successfully fledge young.

The study also demonstrated the cost of that success can be high. When local wetland conditions are good, many females nest successfully and female survival during the breeding season increases. The unfortunate result of this success comes the following winter – female survival during non-breeding seasons is lowest after a breeding season with good wetland conditions. Conversely, during dry breeding seasons, when many hens choose not to nest, survival during the following non-breeding season is higher.

The relationship is likely a result of females investing significant amounts of energy raising a brood in good wetland conditions. They end the breeding season in poor body condition — just when they need to molt feathers and build fat reserves for fall migration, both costly annual events. When females begin these activities late in the breeding season, and in poor body condition, researchers believe it is more difficult for them to prepare for the fall migration, which has a direct and negative impact on their survival rates. 

So, what can we do?

Maintaining, improving and restoring wetland connections for when females start heading back south is one of the most important activities we can take. These birds use state and federally managed ‘semi-permanent’ wetlands (i.e., those with open water throughout the growing season in most years) across the Intermountain West as gas stations to ”top off” their tanks during migration, allowing them to rest and recover from their travels. These publicly owned and managed wetlands comprise more than 60 percent of semi-permanent wetlands in the region, creating the connections migratory birds need to travel between breeding and wintering grounds.
Quality management of these wetlands provides the fuel for migration and keeps these linkages intact, so the cycle can repeat itself next year.

And it all begins with data derived from a duck’s nose ornament – ain’t wildlife conservation grand!

Among conserved public lands and waters, wilderness is a category unto itself. It is land and water designated by Congress for special protection under the Wilderness Act of 1964. Designated wilderness is untrammeled … primeval … natural.

As this week’s National Wildlife Refuge System photo essay, Wilderness! There’s Nothing Like It, explains, “A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain.”

In the United States, there are 765 designated wilderness areas comprising about 109 million acres in 44 states and Puerto Rico. The U.S. Fish and Wildlife Service manages more than 20 million acres of designated wilderness in the Refuge System. There are 75 wilderness areas on 63 units of the Refuge System in 26 states.

“It’s a cliché, but I find that designated wilderness is different from other public lands in a similar way that a church is different from other buildings,” says Jennifer Johnston, a graduate student who has worked in wilderness areas. “To a much greater degree than other public lands, wilderness requires restraint: voluntary limitations on what you can and cannot do.”

Conservation Law Enforcement Officer Helps More Than Manatees

The manatee is one of the world’s natural treasures, and people visit Florida every year to see these imperiled animals.

As Manatee Awareness Month wraps up, let’s not forget those who protect these animals and often go far beyond manatee conservation.

Andy Berrey is a Conservation Law Enforcement Officer, or CLEO, with the U.S. Fish and Wildlife Service. His primary job is enforcing Manatee Protection Zones in Florida, which provide Endangered Species Act protections to manatees

Because the largest cause of human-related manatee mortality in Florida is watercraft collisions, his job is key to manatee conservation.

But speeding boats can be dangerous to more than manatees, and last month, it wasn’t just manatees that benefitted from his patrol in the Harbor Branch Slow Speed Zone.

CLEO Berrey, Federal Wildlife Officer Anibal Vasquez of Pelican Island National Wildlife Refuge, and a Coast Guard officer rescued a woman who had been knocked out of her kayak by a large and dangerous wake caused by several large vessels violating Protection Zone speed restrictions. CLEO Berrey remembers that the woman was “out of breath, fatigued and wearing an oversized life vest that was unzipped.”

The rescuers took the woman to a nearby island where her family was waiting for her. The woman said she was sure she could not have made it to the island or out of that dire situation without the lifesaving skills of these officers.

And yes, the officers also had a chat with the large vessels that were causing the problems.

CLEO Berrey says one of the best parts of his job is “seeing tangible results because of our efforts.” Not much more tangible than a life saved.

Wild Facts About Wild Turkeys

   wild turkeys wichita mtns nwrWild tom (male) turkeys parade with fanned tail feathers at Wichita Mountains Wildlife Refuge in Oklahoma. A tom is also known as a gobbler. Photo by Larry Smith, Flickr Creative Commons

What more is there to know about those funny birds that help define Thanksgiving?

You’d be surprised. Odds are turkeys are even wilder than you thought. 

Amuse your holiday guests with some offbeat turkey trivia presented by the National Wildlife Refuge System. 

Then, when you’re ready to walk off your feast, consider pointing your feet toward some scenic outdoor spots where you might see the native game birds in the wild. Some of the best of those turkey-hangout spots: national wildlife refuges, dedicated to conserving habitat for America’s wildlife. Refuges are closer than you think.  In the same photo feature, we tell you just where to look.

Test yourself. Here’s a sample Q from the story: 

How can you tell a turkey’s sex and age?

  1. By the number of its tail feathers.
  2. By the shape of its droppings.
  3. By the length of its wattle.

And the answer is….. B. Yes, the droppings have it. Male droppings are j-shaped; female droppings are spiral-shaped. No kidding. The larger the diameter, the older the bird.  

How about places to maybe catch a glimpse of turkeys at large? 

If you thought you had to live in the Northeast or Midwest to see turkeys in the wild, think again.  Here, for example, are two spots with turkeys galore:

St Marks National Wildlife Refuge, Florida

To boost your chances of seeing turkeys, drop your car speed to a crawl. “Turkeys are sensitive to the movement of vehicles,” says ranger David Moody. Or get out and walk, slowly. Turkeys like the open terrain of the longleaf pine sandhill ecosystem along the Florida National Scenic Trail, almost 50 miles of which go through the refuge.

Hundreds of Rio Grande turkeys hang out here. The North and South Auto Tour Loops are good places to spot some. Other good spots: along the Rio Viejo Trail, the John Taylor Memorial Trail or the bike trail on the east side service road of the Low Flow Conveyance Channel.

Happy Thanksgiving! Enjoy your feast and our online story — one of a series of photo features that highlight the wildlife and recreation at national wildlife refuges. A new story is posted on the Refuge System home page each Wednesday.

Thanksgiving: Brought to You By Pollination

Thanksgiving is almost here and before we know it, we will be gathered around the dinner table surrounded by friends, family and neighbors, sharing what we are all most thankful for. While we usually take the time to be thankful for our loved ones, how many of us take the time to thank the small critters who have a big role in our lives?

Take a Moment to Thank a Pollinator

When you pass the cranberry sauce down the table or are waiting to dig into the delicious feast, take a moment to notice just how much of our Thanksgiving foods are the product of successful pollination. Hard-working animals like hummingbirds, bats, bees and butterflies pollinate more than 75 percent of our flowering plants and nearly 75 percent of our crops. What better way to share this powerful message with others than by cooking and eating, something we all love!

Thanksgiving pie Photo by Nate Pesce at Forte Meade

Everything including the pumpkin pie, the onions and celery in the stuffing, broccoli and cauliflower, the rub on the turkey, even the glaze on the cornbread is the product of pollination. This doesn’t even count the dozens of spices we use or the after-dinner coffee!


Ways to Thank a Pollinator:

  1. Create a pollinator garden

  2. Reduce pesticides wherever possible

  3. Join citizen science efforts around pollinators

  4. Learn more about work to save the monarch

What is Pollination, Really?

Pollination involves the movement of pollen from one plant to another when animals travel from flower to flower. This pollen transfer allows most of our fruits, veggies, nuts and seeds to develop and grow. Without this process, many plants would not produce food for humans and wildlife alike.

The monarch butterfly, a well-known pollinator species, serves as an indicator of our environment’s health. Its population is declining, which means other pollinators and their habitats are, too, but all is not lost -- you probably won’t have to do without blueberries (another food requiring pollinators). The charismatic monarch may be the answer. Because they rely on habitat throughout the United States during their magnificent migration to Mexico each fall, conservation for monarchs protects other pollinators like bees, bats, moths and flies.

With preparations for Thanksgiving well underway, take a moment to thank a pollinator this season. The video below shows how different our Thanksgiving would look if it were not for these powerful critters. To help support monarch and pollinator populations, plant flowers that are native to your area and reduce your use of pesticides! Learn how you can help save the monarch and other pollinators.

Happy Thanksgiving! We’re thankful for you!

On the Wings of Change: Bringing Some Predictability to the Uncertainty of our Changing Climate

By PATRICIA HEGLUND

When I was a young biologist, more than 30 years ago, I was stationed on Adak Naval Air Station at Aleutian Islands National Wildlife Refuge (now part of Alaska Maritime National Wildlife Refuge). Out in the Aleutians, the weather was always changing. It could be dead calm one minute and gale force winds in another. Rain squalls would blast from above, pelting your face with millions of icy needles for a few minutes and then the sun would break through. Heavy fog could roll by on 50-knot winds for days on end, and then skies would suddenly clear. The weather was so variable that the Nightly Navy News weather report was called, “Today’s Weather Was…” The unpredictability of the Aleutian weather was, well, predictable and thus, something we were well-prepared for.

Today, climate change is throwing an increasing number and magnitude of unexpected extreme weather events at wildlife and land managers. Our uncertainty about the impacts of such change is something managers need to get a hold of so that we can prepare for and respond to such change. In 2011, the Service partnered with NASA’s Ecological Forecasting Program and the University of Wisconsin-Madison to look at the potential impacts of climate change and extreme weather on bird populations on national wildlife refuges in the continental United States.

Birds, and all wildlife, are now experiencing a higher frequency of extreme events, such as droughts or heavy rains, in some places where extreme events were once rare. When combined with higher temperatures, an extreme event can affect the availability of critical resources and be more than a species can bear. As a result, wildlife may move to more suitable areas, abandon breeding attempts or even die. In a recent paper, Dr. Sebastian Martinuzzi and others reported that droughts are expected to become more frequent on some wildlife refuges, particularly in the Southwest, where increasing temperature may already be pushing the limits of some species, so we know we will need strong management there.

   map of Current suitable climate space vs. projected suitable climate space for breeding wood thrush. Current suitable climate space vs. projected suitable climate space for breeding wood thrush.

Even in other areas, drought may have a profound effect on birds. Drs. Brooke Bateman and Andrew Allstadt developed models suggesting that drought and precipitation are particularly important  in shaping the suitable climate range for breeding wood thrush. The projected increase in drought conditions in the southern United States may influence the loss of the region’s suitability as future breeding habitat for the wood thrush by the end of the century. Suitable climate conditions, however, are projected to expand north and east.

   map of Current suitable climate space vs. projected suitable climate space for breeding grasshopper sparrow.Current suitable climate space vs. projected suitable climate space for breeding grasshopper sparrow.

The grasshopper sparrow needs a more even combination of temperature and precipitation conditions, although it appears to favor wetter conditions like those projected for the Midwest in the future. So while its suitable climate range is projected to shrink in the south and west, it is also projected to expand north and east.

Armed with projections like these, we are better able to think about alternative actions the Service can take in response to climate change.

Even in the face of an uncertain climate future, knowing the potential magnitude of change allows the Service to better prepare and act with intention.

Coastal marshes are a habitat she has known and loved since she was a child. But today, salt marshes are facing new and unprecedented threats from climate change. We asked her to talk to us about the important role salt marshes play in protecting coastlines and building coastal resiliency.

Q: What are salt marshes and what makes them important?

Susan: Salt marshes are exciting places to work! They are dynamic areas. Salt marshes form where rivers meet the sea and where the velocity of water is slow enough to allow the sediment to deposit and for plants to take root. Over time, as salt marshes continue to grow, they rise in elevation and expand outward horizontally.

They support a wide variety of wildlife that’s specialized to live in this salty, tidal environment, everything from micro biota to birds such as the saltmarsh sparrow to numerous species of mammals and fish. They also provide excellent services, such as storing carbon, filtering water and providing natural defenses against storms by buffering the force of both storm surges and storm waves.

Q: Let’s talk about storms—how did Hurricane Sandy change the way we think about protecting coastal communities?

Susan: The coast was forever changed as was our perception of what it means to live along the coast. We saw the tremendously destructive force of what nature can do, but we also saw how this force can be lessened by having salt marshes in place to protect our shores.

After Hurricane Sandy, I think many of us woke up to the challenge of having to think about our coastal systems in new ways. How might we redesign our coasts so that in some areas we could restore the natural systems, like salt marshes, that can provide more natural flexibility and protection from storm surge, big storm waves or even additional rainfall?

Q: How do we prepare for future storms and sea-level rise and stay resilient?

Susan: Salt marshes play a vital role in the resiliency of coastal systems. Imagine if this salt marsh was not here. There would be no buffer from the turbulence of storms. And because healthy salt marshes can grow higher in elevation, they can provide a continuing protection to human communities if sea levels don’t rise too high too quickly. By being able to handle the force of storms and recover quickly, we say that salt marshes are resilient and they pass this protection on to surrounding human communities.

We’re also using all kinds of new techniques to restore coastal marshes and improve resiliency. Thin-layer deposition is one example. It uses clean dredge sediments to build up the marsh surface elevation to a height that’s optimal for the salt marsh grasses to continue to build the marsh on their own over time. We have several thin-layer deposition projects on national wildlife refuges as a result of Hurricane Sandy funds [for example, at John Chafee National Wildlife Refuge in Rhode Island and Edwin B. Forsythe National Wildlife Refuge in New Jersey].

Q: You’ve worked in coastal marshes for a long time—how has your work changed and what do you see for the future?

Susan: A lot has changed. We no longer talk about restoring a salt marsh to the configuration it had in the 1600s. Now we talk about restoring the trajectories of salt marsh-building forces so that a salt marsh can sustain itself and have a high degree of integrity over time.

With super storms, climate change and their effects, we’re seeing unprecedented forces placed on the coast. It’s like Godzilla is walking all over our picnic and we are trying to figure out how best to prepare ourselves, how best to respond to this climate change Godzilla.  I may be exaggerating a little bit, but maybe only a little bit because it has been such a challenge to us.

Some of the models predict that our coastlines are going to be entirely changed by sea-level rise in the next 100 years and I worry a great deal about the kind of planet that my nieces and nephews and their children will inherit.

I take hope in realizing it is not just me alone, but within the family of the U.S. Fish and Wildlife Service and my family of other professional scientists, there are a lot of us that are concerned about the same thing. We want to pass on a healthy planet to future generations. If we can bring these salt marshes 50-75 years into the future, I think we will have done a service for the next generation of scientists, wildlife lovers and folks that live on the coast, a service that they can then build on.

Thinking like a Spruce: The Case for Stewarding Ecological Transformation

By Dr. John M. Morton

White spruce and moose co-exist over most of the North American boreal forest, except northern Alaska. There, long-legged moose have almost finished their colonization of arctic Alaska, following wind-dispersed willows northward as they respond to temperatures warming twice as fast as those in the Lower 48. Invading the treeless tundra just a half century ago, moose are now so common they’re recreationally hunted along the Colville River. Balsam cottonwood, another boreal species, spreads through glacial valleys in the Brooks Range, its seeds dispersing in warming winds.

The white spruce is working hard to catch up to its boreal brethren—moose, willow and cottonwood—which have leapt northward in the warming climate. Tree-rings from spruce on the leading edge of the boreal forest in western Alaska show great growth in recent decades, more so than their counterparts in interior Alaska. But spruce expansion northward is checked by the extreme alpine climate in the Brooks Range, the topographic barrier separating the Arctic Coastal Plain from subarctic spruce forests.

   spruce forestThe white spruce forest thins north of Coldfoot, Alaska, because of the harsh alpine climate. It's quite plausible that a caribou hunter or camper traveling up the Dalton Highway collected firewood near here (as did the author), unintentionally transporting a cone that germinated on the North Slope circa 1999. Photo by John M. Morton/USFWS

Slicing through this barrier, the Dalton Highway (aka “Haul Road”) extends due north 414 miles from just outside Fairbanks to Deadhorse. Sometimes  paved but mostly gravel, it cuts through spruce-covered hills before crossing the Yukon River—heart of the Far North—with a 2,300-foot wooden-decked bridge. Entering the land of midnight sun as it crosses the Arctic Circle, the Dalton Highway passes through Coldfoot—start of the longest service-less road segment (245 miles) in North America—eventually climbing the 4,800-foot-high Atigun Pass in the Brooks Range before descending to Galbraith Lake. Here, the Dalton Highway stretches 130 miles northward across the Arctic coastal plain to where the Trans-Alaska pipeline originates near the Arctic Ocean. 

   onetime northernmost spruce

Along the way, the white spruce forest thins, challenged by a harsher climate as the Dalton Highway traverses northward and upward in elevation. Just north of Coldfoot, as the road ascends the southern flank of the Brooks Range, a wayside sign alerts occasional travelers of the “Farthest North Spruce Tree.” This tree, now girdled in a random act of vandalism, no longer holds that crown. Spruce have sprouted further upslope, moving one woody cone at a time, perhaps 200 meters a year, a Herculean effort to reach the other side of the mountains where the climate becomes more boreal with each passing year. Modeling suggests that goal might happen in 1,000 years if left to natural dispersal in a world of anthropogenic climate change.

White spruce can survive on the coastal plain beyond the mountains. Bob Marshall, wilderness advocate, unsuccessfully sowed spruce seeds above the treeline in the Brooks Range back in 1939. They’ve since been experimentally planted at Toolik Lake, a long-term ecological research site on the coastal plain, where they grow but have yet to produce cones. And in 2008, a single white spruce seedling was found growing along the Dalton Highway near Galbraith Lake, a popular site for caribou hunting on the other side of the mountains. This tree almost certainly sprouted from a cone on a branch that was collected for firewood by hunters or campers as they drove north through spruce forests en route to the North Slope.

A novel boreal ecosystem is indeed fledging on the Arctic Coastal Plain, albeit a depauperate one. Populated by wind-dispersed woody plants such as willow and cottonwood, spruce forests are conspicuously absent as moose work to evade predators and high winds.

So why don’t we just transplant spruce, accelerating what is just a matter of time?

We ‘ologists tend to be cautious, not wanting to display hubris about heady decisions like deliberately manipulating biological communities. So we try to control Old World invasives such as white sweetclover creeping up the Dalton Highway, even as we hesitate to manipulate our native spruce. Our inaction allows the random act of a camper or hunter to move the tree beyond the mountains, a decision that could and should have been thoughtfully weighed. Even after the deed is done, the ‘ologists who documented the first spruce to make it to arctic Alaska in the last several thousand years mused about “whether to protect or pull this likely human-introduced seedling or leave its future to chance.” So much angst about naturalness in a world in which its very climate is no longer natural.

When Aldo Leopold penned “to keep every cog and wheel is the first precaution of intelligent tinkering,” Leopold almost certainly didn’t envision the sixth extinction. Perhaps climate change needs more emphatic recognition as the unidirectional driver it is to better understand that we are part of nature—like it or not—and helping spruce over the mountain is the transformational thinking needed now to ameliorate the unfolding Anthropocene.

The National Fish, Wildlife and Plants Climate Adaptation Strategy

The Service is certainly not alone in working to plan for and respond to a changing climate, and since 2010, it has taken a leadership role in developing and implementing a broad, partner-based framework for helping safeguard our valuable natural resources in a changing climate through the collaboratively developed National Fish, Wildlife and Plants Climate Adaptation Strategy.

Since the strategy’s release in March 2013, federal, state and tribal agencies have been working together to support the strategy’s recommendations. For example:

  • California is working with partners to develop a reintroduction plan for winter-run Chinook salmon that will support a more climate-resilient population.
  • An interagency collaboration, led by BLM, is developing a National Seed Strategy to ensure the availability of appropriate seeds in a changing climate.
  • The Swinomish Indian Tribal Community is modeling future conditions to estimate the impacts from sea-level rise and storm surge on the near-shore environment of the reservation on Puget Sound in Washington.
  •  The Service is working to incorporate climate change considerations into land acquisition and financial assistance programs.

In 2016, the partnership sponsored and launched the first national Climate Adaptation Leadership Award for Natural Resources to recognize exemplary efforts by both federal and non-federal entities to help safeguard America’s living natural resources from climate change.

Efforts in 2017 will include continuing to promote the strategy goals and framework, highlighting examples of climate adaptation at work, and identifying and addressing areas where more work is needed.

Recommendations of Strategy

In addition to describing the impacts of climate change on U.S. natural systems from forests to grasslands to the Arctic, the adaptation strategy lays out a set of goals, strategies and actions, and describes opportunities for multiple sectors to address these challenges.

Key recommendations:

  • Conserve habitat to support healthy fish, wildlife and plant populations and ecosystem functions;
  • Manage species and habitats to protect ecosystem functions and provide sustainable use;
  • Enhance capacity for effective management;
  • Support adaptive management through integrated observation and monitoring;
  • Increase knowledge and information on impacts and responses of fish, wildlife and plants;
  • Increase awareness and motivate action; and
  • Reduce non-climate stressors to help fish, wildlife, plants and ecosystems adapt.
