A Budding Botanist’s Quest for Rare Wildflowers

Six pairs of eyes meticulously comb through the open understory of the hardwood forest. Small green plants blanket the forest floor, having just broken through a thick layer of dead leaves. This forest ecosystem, mixed with just a touch of sunlight, creates the perfect habitat conditions for the rarest orchid east of the Mississippi River, the small whorled pogonia.

“The threatened small whorled pogonia hasn’t been documented here since 2012,”  Johnny Townsend, the state botanist, tells me “Although plants that are commonly associated with the pogonia are found all throughout this area, which is a hopeful sign.”

The small whorled pogonia is found in 18 eastern states and Ontario, Canada, but it still considered rare because their isolated populations usually consist of less than 20 plants. The plant is named for it’s whorled arrangement of five to six leaves just beneath the flower, which stands between 10-14 inches tall. The pononia can be found in older hardwood stands of beech, birch, maple, oak, and hickory trees with an open understory and a thick layer of dead leaves. What makes documenting the pogonia particularly difficult is that it can remain dormant for many years without emerging from the leaves.

While I’m no botanist, discovering new plants and ecosystems turned out to be quite the adventure. On our two separate quests for wildflowers, we discovered other rare and beautiful species, including the smooth coneflower, or Echinacea laevigata, and clematis. We also discovered that small-whorled pogonia has an almost identical lookalike, called Indian cucumber root. You can tell the difference between the two species by looking closely at their stems.

Some other fun finds along the way included a box turtle, some gorgeous fungi, and more wildflowers! The diverse array of species is a great indicator of a healthy habitat.

As we continued our search into the forest, we stumbled onto what we came here for. To our surprise, the small whorled pogonia was preparing to flower, another rare sight! The small whorled pogonia doesn’t flower every year, but when they do, flowers only last a few days.

After documenting the habitat’s slope, sunlight, and proximity to water and the forest’s edge, we continued looking and discovered three more plants nearby. Finding only four small individual pogonia plants may not seem like much, but this small population is a huge step in learning how to protect the species.

Not only was finding this federally threatened orchid rewarding , it gives Service biologists at the Virginia Field Office an idea of how well the plant is surviving when faced with possible threats to their habitat. Projects like roadway repairs, building construction, and forest clearing can all impact this delicate ecosystem’s balance. Finding this population after recent construction in the area is a hopeful sign they will continue to thrive.

Knowing more about these ecosystems also helps biologist make informed management decisions and protect our endangered and threatened species. Click here to learn more about small whorled pogonia and other threatened and endangered species work happening in Virginia!

 

Happy 40th, Endangered Species Act!

7657157752_edd5b96c86_o

We know… 40th birthdays are branded as “over the hill.”

But when it comes to the Endangered Species Act, we just don’t agree (that’s not saying we agree that other 40th birthdays are over the hill, either!). With much of its work just getting started, the Endangered Species Act is much more “40 and fierce.”

Endangered species recovery is complex and difficult work, often requiring substantial time and resources. Just as it takes a long time for species to reach the brink of extinction, it takes a long time to bring them back. Many of the endangered species that have fully recovered were the original species protected under the ESA.

Forty years of hard, dedicated work by federal and state agencies, state and local governments, conservation organizations and private citizens have reaped much success for threatened and endangered wildlife.

We’ve got a lot to be proud of. As we near the anniversary on Friday, we’re celebrating the wildlife that has benefited from the protection of one of the world’s most important conservation laws.

Here are some Northeast state-by-state snapshots (click the links for stories).

CONNECTICUT provides homes to nearly 20 imperiled species, from the roseate tern to the bog turtle and Indiana bat. A portion of Silvio O. Conte National Fish and Wildlife Refuge has protected threatened tiger beetles (and migrating songbirds); restoration of Long Beach West returned the barrier beach to the threatened piping plover and other shorebirds; and a team is watching over one of the last remaining healthy populations of the endangered dwarf wedgemussel, found in the Lower Farmington River.

DELAWARE provides homes to over 15 imperiled species, from the swamp pink lily to the shortnose sturgeon and nesting loggerhead sea turtles. Biologists translocated endangered Delmarva Peninsula fox squirrels to Prime Hook National Wildlife Refuge, and just last year, our analysis showed the species has recovered and suggested removing it from the endangered species list! The Delaware Bay is arguably the most important spring stopover for one of the longest-distance migrants in the entire animal kingdom, the red knot. We proposed to protect the knot as threatened under the ESA, and the Delaware conservation community is out to ensure the Bay continues to provide that crucial place for resting and feeding.

MAINE also provides homes to over 15 imperiled species, from the Furbish’s lousewort plant to the Canada lynx and spawning Atlantic sturgeon.  Maine’s only cottontail, the New England cottontail, is a candidate under review for endangered species protection, and Rachel Carson National Wildlife Refuge, along with other partners and private landowners, is restoring its young forest habitat. Craig Brook National Fish Hatchery has cultured Atlantic salmon for over a century, and partnering organizations are working on restoring the free-flowing rivers, such as the Penobscot, on which endangered salmon depend.

The greatest threats to the bog turtle are the loss, degradation and fragmentation of its habitat from wetland alteration, development, pollution, invasive species and advanced plant growth. The species is also threatened by poaching—collection for illegal wildlife trade. Credit: USFWS

MARYLAND provides homes to more than 25 imperiled species, from the Maryland darter to the sandplain gerardia plant and Kenk’s ampipod. Landowners have partnered with our agency and the USDA-Natural Resources Conservation Service to improve their wetlands for North America’s tiniest turtle, the threatened bog turtle. In 1967, when the Delmarva Peninsula fox squirrel was listed, it could be found in only a handful of counties in the state, and after officials closed the hunting season and re-introduced it to several large farms, populations began to thrive! The Puritan tiger beetle has only four populations, one which is on eroding cliffs in Calvert County and another along the Sassafras River. An interagency team and federal grant funding has made substantial progress in meeting the needs of landowners while promoting the species recovery.

plover

Piping plovers were common along the Atlantic Coast during much of the 19th century, but nearly disappeared due to excessive hunting for the millinery trade. Following passage of the Migratory Bird Treaty Act in 1918, numbers recovered to a 20th-century peak in the 1940s. The current population decline is attributed to increased development and recreational use of beaches since the end of World War II. Credit: Diane Fletcher, Friends of Ellisville Marsh

MASSACHUSETTS provides homes to 20 imperiled species, from the northern red-bellied cooter to the roseate tern and Kemp’s ridley sea turtles. Friends of Ellisville Marsh have provided a community model to protect piping plovers, and volunteers like Judy Besancon on Newbury Beach keep an eye on plover nests. Every year, volunteers scan the Cape Cod beaches to save stranded, endangered sea turtles. Populations of the state’s only native rabbit, the New England cottontail, have dwindled as its young, regenerating forest habitat has disappeared. Experts are using controlled burns to restore this early stage of forest in places like Mashpee.

The Karner blue butterfly, an endangered species, is a small butterfly that lives in oak savannas and pine barren ecosystems from eastern Minnesota and eastward to the Atlantic seaboard. Habitat throughout the range of the Karner blue has been lost through human activity to suppress wildfire, cultivate forests and develop communities. Credit: USFWS

NEW HAMPSHIRE provides homes to nearly 15 imperiled species, from the northeastern bulrush to the Karner blue butterfly and red knot. A strong partnership to protect habitat and rear seeds in captivity kept the quarter-sized Robbins’ cinquefoil flower from extinction and ensured its future on the slopes of the White Mountains. In areas across southern New Hampshire, efforts are underway to conserve the natural habitat of the region’s only native rabbit, the New England cottontail. Much of the life history of the endangered small whorled pogonia remains a mystery, but recent efforts in New Hampshire have clued biologists in to this rare woodland orchid’s specific habitat needs.

Some red knots migrate up to 9,300 miles one way, from the southern tip of South America, along the U.S. coast and up to the Canadian Arctic. Changing climate conditions are already affecting the bird’s food supply, the timing of its migration and its breeding habitat in the Arctic. The shorebird also is losing areas along its range due to sea level rise, shoreline projects, and development. Credit: Gregory Breese/USFWS

NEW JERSEY provides homes to over 20 imperiled species, from the Hirst brothers’ panic grass to the red knot and the Knieskern’s beaked-rush plant. In 1993, biologists confirmed a newly discovered colony of endangered Indiana bats in an abandoned mine near Hibernia, and surveys at Great Swamp National Wildlife Refuge have helped us understand the impacts of white-nose syndrome on the species. New Jersey almost lost its bald eagle population by 1980, but state and federal wildlife agencies creatively put the eagle on the road to recovery. Law enforcement have helped protect threatened bog turtles through investigation of ESA violations, and partnerships with private landowners and USDA-Natural Resources Conservation Service have improved and protected their unique wetland habitat.

NEW YORK provides homes to nearly 30 imperiled species, from the Houghton’s goldenrod plant to the clubshell mussel and (recently proposed for ESA protection) northern long-eared bat. Researchers are finding ways to cultivate the threatened American hart’s-tongue fern in the lab and plant them at suitable sites in New York, home to the largest population of this fern in the entire country! It’s not easy to love a rattlesnake (though we do!), but the eastern massasauga’s numbers here have dwindled. Biologists are returning what it needs most — a home. The Albany Pine Bush Preserve, National Grid, our agency and the state wildlife agency have come together to protect habitat for the endangered Karner blue butterfly (the Preserve releases captive-bred butterflies, too!). Last, certainly the tiniest and most difficult to pronounce but not least, is the Chittenango ovate amber snail. Partners are keeping an eye on the only known living population of this snail.

PENNSYLVANIA provides homes to more than 15 imperiled species, from the Virginia spiraea plant to the sheepnose and snuffbox freshwater mussels. Cherry Valley National Wildlife Refuge was established, in part, to protect threatened bog turtles and their habitat; this year, a natural resource damages settlement helped add 90 acres to the refuge! Additionally, a voluntary program helps landowners restore their wetlands with bog turtle habitat. Our Northeast Fishery Center scientists are following endangered Atlantic sturgeon in hopes of protecting and restoring their habitat. Last year, we worked with Pennsylvania Department of Transportation and other folks to replace a bridge and transplant the protected mussels in Illinois, Ohio and West Virginia waters.

RHODE ISLAND provides homes to nearly 15 imperiled species, from the sandplain gerardia plant to the shortnose sturgeon and foraging leatherback sea turtles. The Roger Williams Park Zoo runs captive breeding programs for both the New England cottontail and American burying beetle, whose last remaining wild beetle population in New England is on Block Island. Avalonia Land Conservancy, our agency and locals have found a way to balance recreational use and conservation of threatened piping plovers and other shorebirds at Sandy Point Island.

VERMONT provides homes to six imperiled species, including the dwarf wedgemussel, the northeastern bulrush plant and the (recently proposed for ESA protection) northern long-eared bat. What were threatened Canada lynx doing in Vermont last year? Biologists are surveying for these secretive creatures to understand the best ways to conserve the species. Ice, floods, drought, and invasions–and the endangered Jesup’s milk-vetch hangs on, thanks to a helping hand from wildlife agencies and partners. In 2001, biologists found that Indiana bats come from New York to summer in the Lake Champlain Valley; this information would become vital when white-nose syndrome hit years later.

VIRGINIA provides homes to more than 70 imperiled species, from the Virginia sneezeweed to the spruce-fire moss spider and Carolina northern flying squirrel. The yellowfin madtom was thought to be extinct here; after its rediscovery, biologists set out to ensure its future in the state, and its range in one river may now extend more than 60 miles! Back Bay National Wildlife Refuge has supported nesting sea turtles for 30 years on the shore of Virginia Beach. The Madison cave isopod isn’t cute and fluffy, but protecting this crustacean has meant safeguarding our water supply. In September 2010, biologists, students and other volunteers put on the largest release of endangered mussels to date in the eastern U.S. (and the work continues!).

WEST VIRGINIA provides homes to more than 20 imperiled species, from the shale barren rock cress plant to to the pink mucket mussel and Virginia big-eared bat. Remember those mussels that were moved to West Virginia from a Pennsylvania bridge project? They included the endangered northern riffleshell. We worked with the West Virginia Division of Natural Resources to install a bat-friendly gate on Trout Cave, a hotspot for hibernating endangered Virginia big-eared bats. We’re also part of the Central Appalachian Spruce Restoration Initiative, which continues to restore the high-elevation red spruce habitat needed by the threatened Cheat Mountain salamander and recovered West Virginia northern flying squirrel.

Whew! Like, we said, a lot to be proud of! And we’re gearing up for a whole suite of efforts in 2014.

Forty and fierce, definitely.

Unraveling the mystery of one of our rarest orchids

Even if you’re lucky enough to stroll past one of the nation’s rarest native orchids, you might not take notice of it.

The modest small whorled pogonia (Isotria medeoloides) grows from a few inches to almost one foot tall and has just single whorl, or circle, formed by five to six leaves around its green stem. If you happen across it on one of the few days out of the year when it is blooming, the plant looks almost like a tiny face, with the mouth as a single yellowish-green flower.

Found in hardwood forests, this pogonia was first discovered in 1814 and has since been considered extremely rare. Populations of the plant appear sporadically from New Hampshire to Georgia, and since the small whorled pogonia was listed as endangered under the Endangered Species Act in 1982, the number of known sites where it occurs has increased from 33 to over 150. Currently, there are 51 known populations of this pogonia located throughout central New Hampshire.

Much of its life history remains a mystery, but recent studies have clued biologists in to this rare woodland orchid’s specific habitat needs.

“Across the Northeast, we’re seeing evidence that increasing small light gaps through the forest canopy can eventually increase the number of plants,” says Susi von Oettingen, a biologist in the Service’s New England Field Office.

This theory has really taken off over the last 10 years, culminating with the publication of a study released earlier this year. But to really understand, we must dig farther back, to East Alton, New Hampshire, in the late 1980s. …Keep reading this story!
