NWRC Scientist Collects Economic Data on Cost Efficiency of Trap Monitor Use. On June 8-12, 2009, a National Wildlife Research Center economist met with Texas Wildlife Services (WS) Operations personnel to continue data collection for a study of the cost efficiency of trap monitors. The economist spent multiple days in the field observing and assisting in the placement of monitors on existing traps, identifying important data variables to be collected, and revising the economic study design. Over the next three months trap-monitor data will be collected by WS Operations staff. This data will be used to calculate potential benefits and costs of trap monitors and identify field settings where trap monitors provide a cost savings.

Scientist Helps German Researcher Studying Namibian Wildlife. A National Wildlife Research Center (NWRC) scientist has been asked by a researcher at the University of Potsdam, Germany, to develop a means of indexing wildlife use of trees scent-marked by cheetahs in Namibia. The scientist has previously collaborated with the German researcher to develop passive tacking indices for small carnivores in the Kalahari Desert. That collaboration led to the current invitation to help develop a camera index for the wildlife using scent-marked trees. These trees are significant features of the landscape and serve as resources to a wide variety of other Namibian wildlife. Indexing their use through the seasons will document the level of the trees’ significance to many wildlife species. This information is potentially important to wildlife conservation by identifying the importance of protecting of a wildlife habitat resource from cutting for firewood or charcoal.

Scientists Assist in Capture of African Wildlife and Training Zambian Biologists. During May 19 -June 10, 2009, two research wildlife biologists from the National Wildlife Research Center, Fort Collins, CO, assisted with immobilizing, capturing, and collecting biological samples from four African lions and two African wild dogs, an endangered species, in and near the South Luangwa National Park near Mfuwe, Zambia. The African Wild Dog Conservation Trust (AWDCT) of New Zealand and the Zambian Wildlife Authority, Lusaka, Zambia requested that the scientists provide their expertise in evaluating disease and the interaction of lions, wild dogs, and spotted hyenas with diseased domestic village dogs. The scientists assisted in training Zambian and AWDTC scientists in wildlife immobilization, and in biological sample collection, preservation and storage. The scientists also gave presentations on rabies and tuberculosis in wildlife to the local Zambian wildlife staff. While conducting the studies, the scientists helped to remove a cable snare from a lion's neck that she had contracted from illegal activities of local poachers. The scientists will analyze data from samples collected over the next few months from Zambia and submit a report that will be used to construct management plans concerning the aforementioned species.

Acorn Woodpeckers Captured for Nonlethal Deterrent Research. From May 18-27, 2009, wildlife biologists from the National Wildlife Research Center (NWRC), Fort Collins, CO, live-captured acorn woodpeckers from Walnut Creek, CA. Acorn woodpeckers were caching large numbers of acorns in the exterior walls of condominiums and houses in the area, causing significant damage. The birds were captured under an approved research study protocol and official scientific collecting permits from the U.S. Fish and Wildlife Service and the California Department of Fish and Game. Capture was delayed until after documented egg-laying dates, and birds observed sitting on eggs or feeding young were not removed. The birds will be used in a study conducted under quality assurance standards. Researchers will evaluate effectiveness of electronic deterrent calls as a nonlethal method for preventing woodpecker damage to utility poles and buildings. Study results should help wildlife managers to balance the concerns of homeowners who are economically impacted by the woodpeckers with those who wish to protect the birds.

Development of Prion Decontaminant. Three scientists from the Wildlife Services National Wildlife Research Center worked with scientists from the private sector to evaluate the ability of specialized enzymes to digest prions. Prions are the infectious agents of transmissible spongiform encephalopathy diseases like chronic wasting disease, bovine spongiform encephalopathy, and scrapie. The scientists used a mouse-adapted scrapie model system to establish a statistically relevant reduction in PrPres prion infectivity compared to control, with 52% of challenged mice surviving until the end of the study period. This initial effort will lead to additional research to refine and further develop this potentially promising means of sanitizing surfaces and areas contaminated with infectious prions.

Scientists Assist with Conservation of African Wildlife. From May 19-June 9, 2009, a wildlife biologist and a wildlife veterinarian from the National Wildlife Research Center (NWRC), Fort Collins, CO, headquarters will assist the African Wild Dog Conservation Trust and the government of Zambia in capturing African lions, spotted hyenas, and African wild dogs to conduct a health evaluation and attempt to determine if transmission of select disease agents, including rabies, canine distemper, and a host of blood parasites, occurs among the wildlife species and with domestic dogs in adjacent villages. Scientists will collect and preserve a number of biological specimens from each of the species and, with proper permits, have them transported to the United States where several university collaborators, including the University of Florida and University of Georgia, will assist with analyses. From this data, a risk assessment of the potential impact of these diseases will be conducted. This information should provide scientific information for the development of species management plans that will benefit the conservation of this valuable African wildlife.

Managing Predators Greatly Enhances Sea Turtle Nest Success. On March 9-13, 2009, a National Wildlife Research Center (NWRC) scientist from Fort Collins, CO, in collaboration with Wildlife Services Operations staff, met with cooperators in southern Florida to establish future directions for protecting sea turtle nests from predation. The scientist presented 2008 sea turtle nesting results when a $12K predator management agreement yielded a record number of hatchling turtles valued at $6-13 million. Results like these formed the bases for an agreement to initiate predator management in the Archie Carr area, and to begin discussions with the town of Jupiter Island, adjacent to Hobe Sound National Wildlife Refuge, to carry out predator management along its beach. Predator monitoring will be especially important for success at the 20-mile Archie Carr beach where nest predation occurs sporadically in hotspots. For further information contact: Dr. Richard M. Engeman, 970-266-6091, Richard.M.Engeman@aphis.usda.gov
Exploring Avenues for Feral Hog and Invasive Python Management. On March 12, 2009, a National Wildlife Research Center (NWRC) scientist from Fort Collins, CO, in collaboration with Wildlife Services (WS) Operations staff, met with staff of the South Florida Water Management District (SFWMD) to discuss feral swine and invasive python control on SFWMD lands. Most questions on hog management on SFWMD lands had already been addressed by WS, including population monitoring, damage estimation, impacts of control versus hunting, habitat recovery, and economic analyses. The invasive Burmese pythons in south Florida are another problem on SFWMD lands and the meeting involved brainstorming applied-research approaches that could lead to practical management tools for pythons. NWRC's Gainesville, FL, field station and Florida WS will play important roles in future python management. For further information contact: Dr. Richard M.

Evaluation of GonaCon in Feral Horses. In fall 2009, Theodore Roosevelt National Park (THRO), Colorado State University, and the National Wildlife Research Center plan to initiate a research project to investigate the potential of contraception as a primary tool to manage the park’s feral horse population. This three-year research study, if approved by the U. S. Environmental Protection Agency, will test efficacy, durability of effects over time, behavior, and side-effects of treatment in controlled experiments with captive, domestic horses and in a field application with feral horses at THRO. There are now about 140 feral horses in the park, while the population management objective is 50-90. Currently, keeping the population stable requires roundups every 3-4 years that are time consuming and have inherent risk for horses and National Park Service staff. Excess horses are sold and it may be difficult to find buyers/homes for excess feral horses in the future. If, at the end of this study, fertility control is deemed a viable tool, multiple benefits could be expected: reduced use of helicopters and their associated risks to horses and park staff, less stress on feral horses from reduced roundup intensity and frequency, cost savings to the park in maintaining a species enjoying strong public support, and increased adoptability of surplus horses.

Use of GonaCon Contraceptive in Dolphins. On April 6, 2009, a scientist from the National Wildlife Research Center will be visiting researchers who work in the U.S. Navy Marine Mammal Program in San Diego to present a talk on the wildlife contraceptive GonaCon. The Marine Mammal Program is interested in using GonaCon on dolphins. Because dolphins have internal testicles, the Navy is unable to perform castration and is looking for ways to control the disruptive rut behavior in male dolphins and prevent pregnancies in working females. The National Wildlife Research Center has offered to partner with the Navy to test the contraceptive. For further information contact: Dr. Lowell Miller, 970-266-6163, Lowell.A.Miller@aphis.usda.gov

Research Biologist Presents Invasive Reptile Report. On March 5, 2009, a scientist from the National Wildlife Research Center (NWRC) field station in Gainesville, FL, and the Wildlife Services (WS) State Director in Florida participated in a community meeting at Boca Grande, FL, to discuss management of the invasive black spiny-tailed iguana population on Gasparilla Island. The native Central American lizards were released on the island around 1980 and have become a major nuisance to Charlotte and Lee county residents and a threat to natural resources. During 2008, NWRC biologists supported operational field work by screening and developing baits, documenting food habits, and quantifying reproductive potential by examining over 800 iguanas. Information obtained included the first documented evidence of black spiny-tailed iguana predation on gopher tortoises, a species of conservation concern in Florida. Additionally, WS operational and research biologists cooperated with landowners to reduce the iguana population on the Charlotte County portion of the island. This work will expand to include both Lee and Charlotte counties in 2009. For further information contact: Dr. Michael L. Avery 352-375-2229, Michael.L.Avery@aphis.usda.gov

Colorado Transportation Managers Seek Help with Prairie Dogs. On March 5, 2009, National Wildlife Research Center (NWRC) scientists hosted a meeting with five biologists and managers from the Colorado Department of Transportation (CDOT). Discussions centered on the development of DiazaCon as a reproductive inhibitor for managing prairie dog populations in CDOT right-of-ways. CDOT can currently undertake construction and maintenance projects only when prairie dog pups are not in the burrows. This often delays projects, resulting in significant monetary impacts (prairie dogs cannot be removed while pups are in burrows). Fertility control to eliminate prairie dog pregnancies would enable CDOT to remove the animals any time during the year. NWRC and CDOT discussions included the potential registration of DiazaCon and the possibility of conducting an efficacy trial on CDOT property to determine if DiazaCon could effectively reduce pup numbers enough so that CDOT could employ spring removal operations.

NWRC Hosts Japanese Wildlife Researcher. On February 24-27, 2009, the National Wildlife Research Center (NWRC) Hilo, HI, field station hosted Dr. Go Ogura, a Japanese wildlife researcher from the Laboratory of Subtropical Zoology, University of the Ryukyus, Okinawa, Japan. Dr. Ogura previously visited Hawaii in 2005 to consult with field station researchers on controlling the small Indian mongoose (Herpestes auropunctatus). As in Hawaii, mongooses, introduced a century ago to control rats and poisonous snakes in agricultural crops, have greatly expanded their range on Okinawa and Amami Island. The mongoose is considered the number one invasive predator in Japan, having severely impacted rare populations of the Okinawa rail, two species of native rodents, the Ryukyu robin, a native woodpecker, a climbing lizard, and several species of indigenous amphibians. Trapping of mongooses in the Ryukyus has not achieved acceptable control levels, so one of Dr. Ogura’s objectives during his visit was to investigate alternative management methods. Field station personnel also assisted in collecting and preparing mongoose DNA tissue samples, which will be used by Dr. Ogura to examine the extent of genetic differences between Japanese and Hawaiian mongoose populations. An NWRC Hilo researcher previously visited Okinawa and Amami and met with Dr. Ogura and other Japanese researchers, who supported initiating partnerships between NWRC and Japan for controlling invasive species.

Valuing and Investing in People
NWRC Logan and Starkville Field Stations Complete an Employee Exchange. Between January 25 and February 6, 2009, two National Wildlife Research Center (NWRC) biological technicians temporarily exchanged duties as each traveled to the other’s field location. One technician traveled from the NWRC Starkville, MS, field station to the NWRC Logan, UT, field station and participated in a variety of activities in sub-freezing and snowy conditions. He was trained on handling coyotes, fed animals, cleaned kennels, assisted with research and maintenance activities, and worked with Wildlife Services Operations to learn about coyote and wolf management. The second technician, in turn, traveled from Utah to Mississippi. She drove through Mississippi mud flew on aerial surveys of double-crested cormorant roosts and pelican loafing sites, assisted with testing of a net launcher for bird capture, and worked on a pelican loafing harassment study. Excellent information, beneficial to both field stations, was shared among all who were involved. It is hoped that the employee exchange also may enhance the potential of field stations to provide personnel and assistance to each other. For further information contact: Dr. John A.

Scientist Works in Florida to Eradicate Introduced Roof Rats from Egmont Key. On February 9-15, 2009, a scientist from the National Wildlife Research Center in Fort Collins, CO, assisted Wildlife Services Operations-Florida personnel in setting up and beginning an eradication of the introduced roof rats on Egmont Key off Tampa Bay. The island is part of the U.S. Fish & Wildlife Service National Wildlife Refuge system and also a Florida State Park because of the historic fort and lighthouse there. The island is popular with bird watchers because of the large number and diversity of ground-nesting birds. The island also has gopher tortoises and nesting sea turtles. A number of these species are federally or state-listed as Threatened & Endangered species. The rats were introduced accidently from barges brought to the island with fill material for shoreline restoration. The rats pose a serious threat to all the ground-nesting native species and could damage historic structures. Wildlife Services personnel cut trails through the heavy brush and established a grid of tamper-proof bait stations over most of the island. Diphacinone (an anticoagulant) rodenticide bait blocks were placed in the bait stations. Bait blocks were also thrown into the dense brush thickets so that all rats would be exposed to the rodenticide. The operation will continue until no rat signs (tracks, droppings) are observed.

Valuing and Investing in People
Award for OvoControl® Contraceptive Research to be Presented. On February 6, 2009, the National Wildlife Research Center (NWRC) received notification it will be awarded the 2009 Governor's Award for Research Impact in Natural Resource Management for its role in the development of OvoControl®, an oral contraceptive bait for Canada geese, ducks and feral pigeons. The award will be presented by Colorado Governor Bill Ritter at a special reception on February 17, 2009. The award ceremony is sponsored by CO-LABS, a consortium of federally funded scientific laboratories, universities, businesses, local governments, and community leaders organized to establish Colorado as a global leader in research and technology. The consortium also enhances the potential for new partnerships, technology transfer, and jobs. The award's review panel was impressed with NWRC's careful study of efficacy, toxicity to other species, standards for safe use, and potential unintended environmental consequences prior to the bait's commercialization.

Providing Wildlife Services
Wildlife Biologists Participate in Polynesian Rat Eradication Effort in Hawaii. On January 6 and 13, 2009, biologists from the National Wildlife Research Center and the Wildlife Services'
Hawaii state office, in cooperation with U.S. Fish and Wildlife Service and the State of Hawaii, aerially broadcast diphacinone rodenticide bait pellets on Lehua Island. The island is a 312-acre crescent-shaped volcanic cone that supports colonies of seabirds such as Laysan and black-footed albatrosses, red-footed and brown boobies, black noddies and shearwaters. Some of these species are threatened by invasive Polynesian rats. Two diphacinone bait drops were used during the rodent eradication operation to ensure there was enough bait to reach every rat during a lethal exposure period. One group of participants in the baiting operation worked on a 240-ft barge stationed near Lehua. The barge served as a helicopter landing zone for loading bait and refueling and employed a geographic information systems workstation for downloading GPS data to track and document bait distribution. A second group of people worked on Lehua Island during broadcasts to monitor bait distribution and remove pellets that landed near albatross chicks. This project will assist the recovery of multiple threatened and endangered species that have few safe havens in the highly altered ecosystems of the main Hawaiian Islands.
