Many wildlife managers and health officials are familiar with the success of the U.S. Department of Agriculture’s (USDA) Wildlife Services National Rabies Management Program (NRMP) and understand the important role it plays in preventing the spread of rabies in North America through a wildlife oral rabies vaccination (ORV) program. But others may not be as knowledgeable or don’t believe wildlife rabies is a concern. How do we help them understand the value of such a program? One way is to show them how our lives might be different if there were no ORV efforts in the United States.

In the United States, wildlife accounts for 92 percent of all reported rabies cases. The raccoon rabies virus variant, in particular, is responsible for significant spillover infection into dogs and cats, as well as other wildlife. In an effort to reduce rabies in wildlife and prevent possible transmission to humans, domestic pets and livestock, NRMP experts and their partners annually distribute more than 6 million ORV baits in 16 states along the Appalachian Mountains and in Texas for raccoons, skunks, gray fox, and coyotes. The benefits of maintaining the ORV zone in the eastern United States are significant for several public health, agricultural, and wildlife management reasons. Specific benefits include reductions in human post-exposure prophylaxis, reductions in livestock and pet losses, and the protection of wildlife resources.

To better quantify the benefits of the NRMP, researchers at Wildlife Services’ National Wildlife Research Center (NWRC) and partners modeled the spread of raccoon rabies over 20 years in the absence of current ORV activities in the East. The forecast included 10 raccoon rabies spread-expansion regions each representing a 2-year timeframe. The combined 10 regions show the extent raccoon rabies is projected to spread after a 20-year period without ORV intervention. The forecast models incorporated three different rates of spread: low (15 km/year), medium (30 km/year), and high (60 km/year) based on historical rates of raccoon rabies spread in the eastern United States. Over the 20-year horizon, spread would extend as far west as the Texas border and western Iowa. However, over a longer time period, the spread would likely continue to the Rocky Mountains, where harsh winters and unsuitable habitat might prevent any further westward movement. Such an expansion would cause approximately $1.1 billion in additional damages due to an increased need in human post-exposure treatments, livestock and pet losses, and impacts to wildlife resources.

Thousands of endangered wildlife or wildlife products are being sold on public websites, a new report by the advocacy group, the International Fund for Animal Welfare (IFAW) has revealed.

As part of a six-week investigative effort, that was launched earlier this year, IFAW investigators scanned 280 virtual marketplaces including eBay and Craigslist , perused listings for advertisements of species protected by the Convention of International Trade of Endangered Species, and documented more than 33,000 items for sale — including stuffed hummingbirds in Belgium, live tortoises in France, and wolf fur coats in Poland — with an estimated total value of more than ten million dollars.

“Wildlife cybercrime poses a sinister, silent threat to endangered species including elephants, reptiles and birds, enabling criminals to go about their grisly business with anonymity,” said Azzedine Downes, President and CEO of IFAW in a statement.

One such threat comes in the form of online ivory trade. Nearly one-third of advertised items were either made or suspected to be made of ivory — most of those advertisements came from websites and posts in China. Though government-approved suppliers can legally sell ivory within the country, China has banned those suppliers from selling it online; yet, the IFAW reported ivory and ‘suspected ivory’ products made up nearly 80 percent of China’s online, endangered-wildlife trade.

“Governments must ensure they have robust laws in place that specifically tackle the unique challenges of wildlife cybercrime supported by sufficient enforcement capacity, while online marketplaces must commit to strong policies that are effectively implemented to prevent their platforms being abused by wildlife criminals,” the report stated. IFAW recommends governments and online marketplaces require sellers to disclose permit information in advertisements for CITES-listed species.

While the IFAW could confirm the legality of a portion of all advertisements as part of its investigation, it admits it cannot determine exactly how many of the items were illegally traded. IFAW did, however, consider the legality of 1,192 advertisements questionable enough to submit its findings to national enforcement agencies.

The U.S. House of Representatives voted to pass the National Defense Authorization Act earlier this week, while the Senate voted to end debate and move forward with the legislation on Thursday. The legislation includes dozens of public land use provisions as legislative riders unrelated to the overall purpose of the bill. [Update: Senate approved the legislation on Friday.  The bill now waits for President Obama’s signature.]

The $585 billion dollar bill’s primary purpose is to direct spending on defense, but key members of the House Natural Resource Committee and Senate Energy and Natural Resources Committee were able to attach roughly 70 land use provisions. The suite of legislation is the first large land use package since 2009 and contains provisions that protect hundreds of thousands of acres of public land, allow development on other public lands, and change regulations on resource permitting on public land. Highlights of the legislative riders are summarized below.

Public Land Protection

Several provisions in the package will combine to designate a total of about 250,000 acres of wilderness in Arizona, Colorado, Nevada, New Mexico, and Washington. Language is also included to protect hundreds of thousands of acres of land near Glacier National Park in Montana from future oil and gas development. Other provisions expand over a dozen national parks and improve public access to parks and wildlife refuges

Public Land Development

In exchange for the protected land, around 100,000 acres of public land would be transferred for private development including copper mines in Arizona and Nevada, and 70,000 acres of the Tongass National Forest of Alaska that will be mostly used for logging.

Public Land Use Regulations

Other provisions affect how permitting of grazing and oil and gas development in public lands is performed. Language is included that will expedite both processes through exceptions to the National Environmental Policy Act (NEPA).

The lands package is not without controversy. Lawmakers and interest groups are split about what the bill will mean for their constituents and members. Outdoor recreation advocates generally applaud the conservation of natural areas, but are wary over certain restrictions to public access for new wilderness areas in the bill. The wilderness and park expansion language was well received within the conservation community, but many are troubled by the mine development, logging, and grazing provisions. Some environmental groups are particularly troubled by the grazing provisions which could imperil sage grouse recovery. Nevertheless, the bill is expected to be signed by the president this week.

A map detailing the journey of a young scalloped hammerhead shark (Sphyrna lewini) swimming between coastal and offshore waters in the Gulf of California may expose a gap in current efforts to protect the endangered species, according to a new online study published in the journal Animal Biotelemetry.

Scalloped hammerheads are endangered with some populations around the world suffering a 50 to 90 percent decline in fewer than 35 years; and the populations living in the Gulf of California seem to be no exception. “In Mexico in the 80s, the sea of Cortes was one of the best places to see these beautiful and majestic animals but at present it’s hard to see even a few,” said Mauricio Hoyos-Padilla, a researcher from Pelagios Kakunja, Mexico and one of the study’s authors, in a press release.

In order to understand juvenile shark behavior, Hoyos-Padilla and a team of researchers baited and captured one male and two female juvenile sharks in the Gulf of California. The researchers surgically implanted a tracking device at the base of each shark’s pelvic fin. Every 30 seconds, the device recorded the depth, sea temperature, and light level of the shark’s surrounding environment. The tag also had a reward notice attached to it, so when local fishermen caught one of the female sharks north of La Paz Bay nearly a year later they knew who to contact. The researchers retrieved the tracking device, downloaded the data, and mapped the shark’s movements throughout the gulf.

Over the course of 10.5 months, the young, three-foot-long, female hammerhead swam over 2,000 miles. Initially, the shark stuck to warm shallow waters along the coast, but eventually swam to offshore habitat within the Gulf of California. By day, the female shark probably swam around offshore islands and underwater mountains called seamounts with schools of other juvenile and adult hammerheads. At night, it would swim away to hunt for prey such as squid and fish at depths of up to 880 feet. “This is the first time we have an idea of their behavior at this stage,” said Hoyos-Padilla.

Understanding where hammerheads swim helps scientists and wildlife managers identify key habitat areas and determine where to focus their efforts. Mexico prohibits commercial fishing from large vessels within 50 nautical miles of the coast, which should help protect sharks in near-shore, nursery areas; but James Ketchum, another of the study’s authors, thinks that may not be enough. “Because of their dependence on both coastal and offshore waters during their early life-stages, we think that they may be more susceptible to fisheries than previously thought,” said Ketchum in the press release. “Current protective measures in Mexico may unfortunately be insufficient.

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) found the wolverine (Gulo gulo), and 13 other species, to be of special concern during a meeting last month. COSEWIC, an independent group of government and non-government experts, lists a species as special concern when a combination of biological factors and identified threats indicate that the species may become threatened or endangered in the near future. The wolverine, which is sensitive to human disturbance, is experiencing declines in its southern range due to habitat fragmentation from increased industrial development.

Although COSEWIC has listed the wolverine as a species of special concern, the species is not automatically listed under the federal Species at Risk Act (SARA). The Minister of the Environment must bring the species before the cabinet for consideration for federal listing under SARA. The government can decide to not list the species, and has denied 30 recommended species listings since 2004. Environment Canada is asking hunters and trappers associations in communities throughout Nunavut to comment on the proposed federal listing of wolverines by January 15, 2015, to help inform the cabinet’s decision.

COSEWIC also found 14 species to be endangered and six to be threatened. However it is uncertain how quickly the Minister of the Environment will bring these species to the cabinet for potential federal listing. Over 100 species that have been reviewed by COSEWIC have not yet been brought to the cabinet. Delaying to list a species may create more problems for the species’ recovery as some recovery actions such as the designation of critical habitat cannot occur until a species is federally listed.
