The U.S. Fish and Wildlife Service’s Necedah National Wildlife Refuge (NWR) and the Whooping Crane Eastern Partnership (WCEP) are celebrating another success in efforts to reintroduce a wild migratory whooping crane population in eastern North America.

Three whooping crane chicks hatched this week at Necedah NWR in central Wisconsin. The first chick to hatch this season was the offspring of wild whooping crane W1-06. W1-06 was hatched and raised in 2006 on Necedah NWR and is the first wild offspring from the eastern whooping crane reintroduction project started more than a decade ago.

The additional two chicks are the offspring of other well-established whooping crane pairs. Sadly, refuge biologists have been unable to locate the first chick in recent monitoring efforts. The chick may have been predated.

“Although we are disappointed by the potential loss of the first chick, we are encouraged by this first successful nesting and hatching of a wild-born chick, from a wild-born parent,” said Necedah National Wildlife Refuge Manager Doug Staller. “Refuge staff is committed to working toward the ultimate goal of a self-sustaining eastern flock of migratory whooping cranes and actively monitors additional nests of whooping crane pairs on the Refuge.”

There are approximately 105 whooping cranes in the eastern migratory population including at least 20 nesting pairs, also a record number for this reintroduced population. In addition to the three chicks hatched in the wild this week at Necedah NWR, three chicks have fledged in the wild during the course of the reintroduction project, which began in 2001.

“The Whooping Crane Eastern Partnership’s focus over the next five years is successful reproduction in the wild flock, and the recently hatched chicks, in addition to the three previously fledged wild-hatched chicks are a very promising start to achieving this goal,” said Joel Trick, acting project leader for the Service’s Green Bay Ecological Services Field Office and WCEP representative. “We continue to work to identify the factors that may contribute to nest failure, and are working to address those challenges through active nest management and captive-reared releases.”

This year marks an important transition for whooping crane recovery efforts at Necedah NWR. The effort has shifted from the population depending upon introduction of captive-reared birds to the population being supported through wild whooping cranes producing eggs, hatching chicks and fledging young.

Since whooping cranes have been absent from the upper Midwest for over 120 years, WCEP plans to continue studying factors that improve reproductive success as well as how reintroduced whooping cranes use the habitats they encounter following release. These data will refine the understanding of what determines overall success for whooping crane reintroduction in the upper Midwest.

Experimental release of stingless parasitic wasps may help Wisconsin control emerald ash borer

News Release Published: May 5, 2011 by the Central Office

Contact(s): Dr. Ken Raffa, UW-Madison (608) 262-1125 or Andrea Diss-Torrance, DNR (608) 264-9247

MADISON – Tiny stingless wasps the size of a grain of rice may someday play a role in controlling the emerald ash borer (EAB) infestation in Wisconsin. The invasive pest has killed millions of ash trees since its discovery in Michigan in 2002.

Emerald Ash Borer - Agrilus planipennis

EAB was accidentally introduced from China within shipments of imported products. It is not a pest in Asia, where it only lives in dying trees, because ash trees there evolved with it and so healthy Asian ash have effective defenses. Unfortunately, there is no evidence of resistance in our ash species.

This spring, scientists with the University of Wisconsin – Madison, the DNR, and USDA-APHIS will introduce three species of stingless parasitic wasps that prey almost exclusively on the ash-killing beetle in a cooperative project. Emerald ash borer was first discovered in Wisconsin near the Village of Newburg in 2008. Since that time, EAB has shown up in Cudahy, Oak Creek, Franklin, West Bend and Victory, and has been trapped in Green Bay and Kenosha.

A Wisconsin Department of Natural Resources grant will help fund the research for the next three years.

Researchers plan to release two species of stingless wasps sometime in May and the third species later in the

summer. The releases are timed according to specific weather conditions and will all be done at the Riveredge Nature Center near Newburg. All three stingless wasp species are native to China and are natural predators of EAB in the beetle’s native range.

The two species that will be released in May parasitize the larval stage of EAB – when the insect lives under the ash bark. They insert their egg-laying appendage (ovipositor) through the outside of the tree and then lay their eggs on the surface or inside the EAB larva. The stingless wasp species that is scheduled for release later this summer parasitizes EAB by depositing its egg inside the egg of the emerald ash borer.

“This experiment will help our understanding of the potential these wasps that may have as part of our attempts to reduce the spread and impacts of the emerald ash borer in Wisconsin,” said Dr. Ken Raffa, UW Madison professor of entomology. “Biological controls, such as these stingless wasps, can be an important component in an overall management strategy that also includes quarantines, education, and chemical treatments. These wasps have undergone intense scrutiny by the USDA to safeguard against harm to native species. So far, 180,000 wasps have been released in 9 states, including Michigan, Illinois, and Minnesota.”

“These tiny, stingless wasps pose no threat to people,” said Andrea Diss-Torrance, DNR forest entomologist. “They do not seek shelter in homes or other buildings as they all overwinter inside their host, EAB, under the bark of ash trees. As adults, these wasps are focused on finding EAB to host their offspring and so stay close to EAB-infested ash trees. Because they are so tiny and at work in the canopy of ash trees, most people will never see them. In fact, it is very hard even for trained entomologists to find the adult wasps in the field. To verify if our introductions are successful, we will have to peel the bark off of EAB infested ash and look for parasitized EAB larvae”

Stingless wasp - Tetrastichus planipennisi

“The effectiveness of these stingless wasps against EAB is uncertain, yet it is clear that reducing EAB populations has a better chance of success when many approaches are employed,” said Jane Cummings-Carlson, forest health specialist with the DNR. “Extensive research conducted by the USDA shows that they are highly selective in going after EAB, so there is some hope that they may eventually be used on a wide scale to help reduce EAB populations, especially in Wisconsin’s forests where there are more than 700 million ash trees. It is very important that we explore every tool available to reduce the ecological and financial impact EAB will have on our urban and rural forests,” said Cummings Carlson.

“It will take some time, roughly five years, before we can assess the potential of these stingless wasps for affecting the population of EAB,” continued Cummings-Carlson. “If it does prove useful, it would be most effective in areas of known infestations since the stingless wasp needs the beetle to complete its life cycle. Cold-hardiness tests indicate the stingless wasps are winter hardy enough to survive from season to season in our climate.”

Nature is already lending a hand when it comes to reducing EAB populations. Native woodpeckers are often attracted to the abundant source of larvae in infested trees. One of our native ground-dwelling stingless wasps feeds exclusively on beetles within the same family as EAB. And in Michigan, scientists recently discovered an entirely different species of native non stinging wasp that preys upon EAB larvae. However, it is clear from the devastation that these agents are not adequate. As with tree defense, the natural enemies that evolved with EAB in China are more effective.

“Key to helping reduce the population of EAB in Wisconsin and in North America as a whole will be finding ways to combat the beetle across large tracts of land,” Cummings-Carlson said. “Currently, our insecticides work well to protect urban trees but are not practical in the forest setting. We really need an effective biological control to help us preserve our native North American ash forests.”

“Riveredge looks forward to this exciting partnership with the DNR and researchers from UW-Madison and we’re honored that they chose Riveredge as the release area,” said Patrick Boyle, executive director of the Riveredge Nature Center. “We all greatly hope that this project yields some positive results that we can share with the community.”

The emerald ash borer is a metallic green beetle about the size of a cooked grain of rice. It was introduced to North America in early 1990s in the Detroit area and has since been responsible for the destruction of millions of trees across 15 states and Canada. It attacks only ash trees.

THE FULL PRESS RELEASE : Interior Announces Next Steps in Protection, Recovery, and Scientific Management of Wolves

Washington, DC – The Department of the Interior’s U.S. Fish and Wildlife Service announced today that it is proposing to delist biologically recovered gray wolf populations in the Western Great Lakes, and – in accordance with recently enacted legislation – reinstating the Service’s 2009 decision to delist biologically recovered gray wolf opulations in the Northern Rocky Mountains.

“Like other iconic species such as the whooping crane, the brown pelican, and the bald eagle, the recovery of the gray wolf is another success story of the Endangered Species Act,” said Secretary of the Interior Ken Salazar. “The gray wolf’s biological recovery reflects years of work by scientists, wildlife managers, and our state, tribal, and stakeholder partners to bring wolf populations back to healthy levels.”

Gray wolves were originally listed as subspecies or as regional populations of subspecies in the lower 48 states and Mexico under the ESA and its predecessor statutes. In 1978, the Service reclassified the gray wolf as an endangered species across all of the lower 48 states and Mexico, except in Minnesota where the gray wolf was classified as threatened.

Gray Wolves in the Northern Rocky Mountains

As part of today’s actions, the Service is publishing a final rule – as directed by legislative language in the recently enacted Fiscal Year 2011 appropriations bill – reinstating the terms of a 2009 rule removing gray wolves in a portion of the Northern Rocky Mountain Distinct Population Segment (DPS) encompassing Idaho, Montana and parts of Oregon, Washington and Utah from the Federal List of Endangered and Threatened Wildlife. Gray wolves will remain listed under the ESA in Wyoming, although the Service is working closely with that state to develop a wolf management plan that would allow wolves in Wyoming to be removed from the list in the future.

The Service and the states will monitor wolf populations in the Northern Rocky Mountain DPS and gather population data for at least five years under a post-delisting monitoring plan previously approved by the Service.

“We are implementing the recent legislation that directs the delisting of the gray wolf in most of the Northern Rocky Mountains,” said Interior Deputy Secretary David J. Hayes. “As with other delisted species, we will be applying the Endangered Species Act’s post-delisting monitoring requirements to ensure that wolf populations remain robust, while under state wildlife management.”

Gray Wolves in the Western Great Lakes

The Service is also publishing a proposed rule to remove gray wolves in the Western Great Lakes area — which includes Minnesota, Michigan and Wisconsin, and portions of adjoining states — from the list of endangered and threatened species because wolves have recovered in this area and no longer require the protection of the ESA.

“Gray wolves in the Western Great Lakes are recovered and no longer warrant protection under the Endangered Species Act,” said Acting Service Director Rowan Gould. “Under this proposed rule, which takes into account the latest taxonomic information about the species, we will return management of gray wolves in the Great Lakes to state wildlife professionals. We are confident that wolves will continue to thrive under the approved state management plans.”

As part of the proposed rule, the Service would revise the range of the gray wolf (the species Canis lupus) by removing all or parts of 29 eastern states due to newer taxonomic information indicating that the gray wolf did not historically occur in those states. The Service is also initiating status reviews of gray wolves in the Pacific Northwest and Southwest to determine the appropriate entity and listing status of that entity in those areas, as well as seeking information on a newly-recognized species, the eastern wolf (Canis lycaon), throughout its range in the United States and Canada. The Service is seeking public comment as part of this process.

The proposed rule to remove wolves in the Western Great Lakes from the ESA, as well as the final rule reinstating the 2009 final delisting rule for the Northern Rocky Mountain DPS as directed by the 2011 Full-Year Appropriations Act will publish in the Federal Register on May 5, 2011. The final rule for wolves in the Northern Rocky Mountain DPS will be effective immediately upon publication.

Written comments on the proposed rule for wolves in the Western Great Lakes may be submitted by one of the following methods:

  • Federal eRulemaking Portal
  • Follow the instructions for submitting comments to Docket No. [FWS-R3-ES-2011-0029].

Comments must be received within 60 days, on or before July 5, 2011. The Service will post all comments ONLINE. This generally means the agency will post any personal information provided through the process. The Service is not able to accept email or faxes.

Public hearings for the proposed removal of wolves in the Western Great Lakes and proposed removal of eastern states from the gray wolf listing will be held May 18 in Ashland, Wisconsin, and on June 8 in Augusta, Maine. More information on the hearings will be available ONLINE or by calling 612-713-5350.

Following the close of the comment period, the Service will consider all new information and other data and make a final decision on the proposal to remove the Western Great Lakes DPS of wolves from the ESA and revise the range of the gray wolf in the eastern U.S. In the meantime, gray wolves in the Western Great Lakes area will remain classified as endangered, except in Minnesota where they will remain threatened. Gray wolves will also remain classified as endangered in the western U.S., except where delisted in the Northern Rocky Mountains DPS in accordance with Congressional action and where found in experimental populations, until status reviews and rulemaking processes are completed.

The ESA provides a critical safety net for America’s native fish, wildlife and plants. The Service working to actively engage conservation partners and the public in the search for improved and innovative ways to conserve and recover imperiled species.
