Media details for  21:
Media can visit the reintroduction site on Tuesday, June 7 (rain date: Wednesday, June 8) and Tuesday, June 21 (rain date Wednesday, June 22). All involved in the reintroduction will meet at the Missouri Department of Conservation Office in El Dorado Springs, MO, at 2 p.m. on June 7 or 21. All media representatives planning to visit the site need to call in advance so that the reintroduction team will know who is coming. Everyone needs to caravan to the site due to its remote location. Call the Zoo's public relations office to get the address of the Conservation Office, to reserve your news organization's spot in that caravan and for contact phone numbers—cell phone service is not readily available.

Endangered American Burying Beetles from Saint Louis Zoo Set to be Introduced in Southwest Missouri

Approximately 540 Saint Louis Zoo-bred American burying beetles (270 pairs) are being reintroduced in Southwest Missouri on June 7 and June 21, 2016. The American burying beetle is the first endangered species to be re-introduced to the state of Missouri.

Fourteen members of the Zoo ALIVE teen volunteer program at the Zoo are helping prep the beetles for reintroduction and will be participating in the actual reintroduction on June 21 (ALIVE stands for Active Leaders In Volunteer Education).

In preparation for the reintroduction, the beetles are paired and marked by "notching" each beetle's elytra, or hard wing covers. The notch distinguishes captive-bred and wild beetles, and beetles are also notched based on release location.

This is the fifth year beetles are being reintroduced into the same area in Southwest Missouri. Last year, approximately 400 beetles were reintroduced. In 2014, approximately 350 beetles were reintroduced. In 2013, approximately 600 beetles were reintroduced—more than double the 236 beetles reintroduced in the same area in 2012. The 2012 reintroduction marked the first time ever this beetle had been reintroduced in Missouri.

This project is jointly managed by the Zoo's WildCare Institute Center for American Burying Beetle Conservation; the U.S. Fish & Wildlife Service; the Missouri Department of Conservation; and The Nature Conservancy. Staff from partner organizations and local volunteers also help with the reintroduction.

As in previous years, the burying beetle is being reintroduced across the Wah' Kon-Tah Prairie in St. Clair and Cedar counties on land jointly owned and managed by the Missouri Department of Conservation and The Nature Conservancy.

The beetle release process involves digging holes, or plugs, at specially selected sites, placing the carcass of a quail and a pair of notched beetles in each cavity and replacing the plugs.

This process simulates a natural underground setting for the beetles' life cycle. The plug sites will then be monitored for signs of breeding activity by checking for larvae, and later, new adult beetles.

Recent surveys indicate that 17 of the endangered beetles made it through the winter this year.

"We are really encouraged that each year we are finding more and more naturally produced beetles," said Saint Louis Zoo Zoological Manager for Invertebrates Bob Merz. Merz is also director of the American Burying Beetle Center that is part of the Zoo's 13-center WildCare Institute dedicated to saving animals across the globe and at home. "We know that our beetles are producing offspring on the prairie and that these offspring are surviving through the winter."

Because the beetles do not necessarily emerge from their underground winter hibernation all at once, the number of beetles found in the spring surveys is not that telling. "There is still a chance that more can be found," said Merz.

By the time this carrion feeder was placed on the United States federal endangered species list in 1989, the only known remaining population was in Rhode Island. Since its federal listing, field surveys have discovered populations in six other states in the Midwest but none in Missouri, where surveying for the endangered beetles has been the focus of the Zoo's American burying beetle conservation efforts for several years.

"The beetle was last seen in Missouri in the mid-1970s, and for a decade, the Zoo had monitored for existing American burying beetles but with no success," said Merz. "Our contribution to reintroduction efforts by returning the beetle to parts of its former range is the beginning of the recovery of this beautiful beetle."

BACKGROUND: The Saint Louis Zoo's WildCare Institute Center for the Conservation of the American Burying Beetle in Missouri. Genetic work organized by the Center for American Burying Beetle Conservation provides a firm base for both reintroductions and breeding programs. The Center is involved in a number of important developments for this species. Through its WildCare Institute, the Zoo focuses on wildlife management and recovery, conservation science, and support of the human populations that coexist with wildlife in 13 conservation hotspots around the globe, including four in Missouri. The WildCare Institute also includes the Institute for Conservation Medicine, which focuses on a holistic approach to research on wildlife, public health and sustainable ecosystems to ensure healthy animals and healthy people.
