Another “sneak attack” on wildlife from GOP
Feb 3rd
Disguised as “Sportsmen’s Heritage Act, ”Legislation Would Also Roll Back Public-lands Protection, Promote Polar Bear Trophy Hunting
WASHINGTON— The U.S. House of Representatives will vote Tuesday on H.R. 3590, the misnamed “Sportsmen’s Heritage and Recreational Enhancement Act.” Under the guise of expanding hunting and fishing access on public lands, the Republican-supported bill aims to prevent the Environmental Protection Agency from protecting millions of birds and other animals from lead poisoning. The extremist legislation also contains provisions to undermine the Wilderness Act, dispense with environmental review for projects on national wildlife refuges, and promote polar bear hunting.
“Another cynical assault by House Republicans to roll back protections for public lands and wildlife,” said Bill Snape, senior counsel at the Center for Biological Diversity. “This supposed ‘sportsmen’s legislation’ would actually jeopardize the health of hunters, promote needless lead poisoning of our wildlife, and prevent hunters, anglers and other members of the public from weighing in on decisions about how to manage 150 million acres of federal land and water.”
H.R. 3590 seeks to exempt toxic lead in ammunition and fishing equipment from regulation under the Toxic Substances Control Act, the federal law that regulates toxic substances. The EPA is currently allowed to regulate or ban any chemical substance for a particular use, including the lead used in shot and bullets. Affordable, effective nontoxic alternatives exist for lead ammunition and lead sinkers for all hunting and fishing activities.
Spent lead from hunting is a widespread killer of more than 75 species of birds such as bald eagles, endangered condors, loons and swans, and nearly 50 mammals. More than 265 organizations in 40 states have been pressuring the EPA to enact federal rules requiring use of nontoxic bullets and shot for hunting and shooting sports.
“There are powerful reasons we banned toxic lead from gasoline, plumbing and paint — lead is a known neurotoxin that endangers the health of hunters and their families and painfully kills bald eagles and other wildlife,” said Snape.
H.R. 3590 would also exempt all national wildlife refuge management decisions from review and public disclosure under the National Environmental Policy Act and allow the import of polar bear “trophies” from Canada. The Republican-controlled House approved similar “Sportsmen’s Act” legislation in 2012 by a vote of 274-146, but the bill was stopped in the Senate.
Background
Despite being banned in 1992 for hunting waterfowl, spent lead shotgun pellets from other hunting uses continue to be frequently ingested by waterfowl. Many birds also consume lead-based fishing tackle lost in lakes and rivers, often with deadly consequences. Birds and animals are also poisoned when scavenging on carcasses containing lead-bullet fragments. More than 500 scientific papers have documented the dangers to wildlife from lead exposure. The U.S. Fish and Wildlife Service calculates that more than 14,000 tons of toxic lead shot is deposited in the environment each year in the United States by upland bird hunting alone.
Lead ammunition leaves fragments and numerous imperceptible, dust-sized particles that contaminate game meat far from a bullet track, causing significant health risks to people eating wild game. Recent scientific studies show that hunters have higher lead levels in their bloodstream, and more associated health problems, than the public at large. Some state health agencies have recalled venison donated to feed the hungry because of dangerous lead contamination from bullet fragments.
There are many alternatives to lead rifle bullets and shotgun pellets. More than a dozen manufacturers market hundreds of varieties and calibers of nonlead bullets and shot made of steel, copper and alloys of other metals, with satisfactory-to-superior ballistics. A recent study debunks claims that price and availability of nonlead ammunition could preclude switching to nontoxic rounds for hunting. Researchers found no major difference in the retail price of equivalent lead-free and lead-core ammunition for most popular calibers.
Hunters in areas with lead ammunition restrictions have transitioned to hunting with nontoxic bullets. There has been no decrease in game tags or hunting activity since state requirements for nonlead hunting went into effect in significant portions of Southern California in 2008 to protect condors from lead poisoning. California recently passed legislation to transition to lead-free hunting statewide by 2019.

CU study: Some primates sleep in caves for safety
Dec 4th
The ring-tailed lemurs may be opting to sleep in caves for several reasons, said University of Colorado Boulder anthropology Associate Professor Michelle Sauther, who led the study. While the cave-sleeping behavior is likely important because it provides safety from potential predators, it also can provide the primates with access to water and nutrients, help to regulate their body temperatures during cold or hot weather and provide refuge from encroaching human activities like deforestation, she said.
“The remarkable thing about our study was that over a six-year period, the same troops of ring-tailed lemurs used the same sleeping caves on a regular, daily basis,” she said. “What we are seeing is a consistent, habitual use of caves as sleeping sites by these primates, a wonderful behavioral adaptation we had not known about before.”
A paper on the subject appeared in the November issue of the journal Madagascar Conservation and Development. Funding for the project came from Primate Conservation Inc., the International Primate Society, the American Society of Primatologists, the National Geographic Society, CU-Boulder, the University of North Dakota, Colorado College and the National Science Foundation.
Although sleeping in caves by ring-tailed lemurs — which are found only in Madagascar — has likely been going on for millennia, it is only now being recognized as a regular behavior, said Sauther. The endangered Fusui langurs, slender, long-tailed Asian monkeys roughly 2 feet tall, also have been documented sleeping in caves but as a direct result of extreme deforestation, moving from cave to cave every few days. There also have been isolated reports of South African baboons sleeping in caves.
Ring-tailed lemurs are easily identified by their characteristic, black and white ringed tails, which can be twice as long as their bodies. They weigh roughly 5 pounds with a head-body length of up to 18 inches and are highly social, congregating in groups of up to 30 individuals. Sporting fox-like snouts and slender frames, they are unusual among lemurs, spending a considerable amount of time on the ground feeding on leaves and fruit and socializing, said Sauther.
In “gallery forests” near rivers, ring-tailed lemurs regularly sleep high in the canopies of tall trees. But in “spiny forests,” most of the trees with woody stems are covered in rows of spines, making them uncomfortable as well as dangerous sleeping sites because predators can easily climb them, Sauther said. The new study documents their cave sleeping behavior in the dry spiny forest habitat adjacent to limestone cliffs.
The lemur observations were made at the 104,000-acre Tsimanampesotse National Park and the Tsinjoriake Protected Area in southwestern Madagascar between 2006 and this year. The research team used field observations and motion-detector camera traps to chart the behavior and movements of 11 different troops of ring-tailed lemurs.
One of the early clues to the cave sleeping by the lemurs was their presence on limestone cliffs adjacent to spiny forest trees or on the ground when Sauther’s research team arrived at the study sites early in the morning. “They seemed to come out of nowhere, and it was not from the trees,” she said. “We were baffled. But when we began arriving at the study sites earlier and earlier in the mornings, we observed them climbing out of the limestone caves.”
The primary predator of the lemurs is a cat-like, carnivorous mammal called a fossa native only to Madagascar that is closely related to the mongoose and may weigh up to 20 pounds. Fossil evidence shows a cougar-sized relative of the fossa that only became extinct several thousand years ago likely preyed on lemurs as well, she said.
There is evidence that some early ancestors of humans in South Africa may have used caves to protect themselves from predators, said Sauther. The remains of hominids going back several million years have been found inside or near limestone caves there, and some fossil bones have evidence of damage consistent with the bite of saber-toothed cats.
“We think cave-sleeping is something ring-tailed lemurs have been doing for a long time,” she said. “The behavior may be characteristic of a deep primate heritage that goes back millions of years.”
Co-authors of the new study included Associate Professor Frank Cuozzo of the University of North Dakota, Ibrahim Antho Youssouf Jacky, Lova Ravelohasindrazana and Jean Ravoavy of the University of Toliara in Madagascar, Krista Fish of Colorado College in Colorado Springs, Colo., and Marni LaFleur of the University of Veterinary Medicine in Vienna. Fish and LaFleur are former CU-Boulder students of Sauther.
Sauther co-directs the Beza Mahafalay Lemur Biology Project in southwestern Madagascar with Cuozzo, a former CU-Boulder doctoral student. Centered at the roughly 1,500-acre Beza Mahafalay Special Reserve, the research focuses on how climate- and human-induced change affects lemur biology, behavior and survival.
Sauther and her team were aided by field observations made by students and faculty from the University of Toliara in Madagascar. In addition, undergraduate and graduate students from CU-Boulder regularly travel to Madagascar to conduct research under Sauther, including students from CU’s Undergraduate Research Opportunities Program, which provides hands-on research and fosters student-faculty relationships.
“I never thought I would have a chance as a CU undergraduate to conduct research in an exotic place like Madagascar,” said former UROP student Anthony Massaro, who was part of a team that trapped ring-tailed lemurs, measured their physical characteristics including dentition, and released them back into the wild. “Dr. Sauther and Dr. Cuozzo mentored and guided me through the process of creating and conducting a unique research project.”
Unfortunately, habitat destruction, including deforestation, is increasing in many parts of Madagascar. In southwestern Madagascar, trees are being harvested for cattle forage, construction materials and firewood, and the mining of limestone there — used for the production of cement, fertilizer and other products — is increasing. Ring-tailed lemurs are now listed as an endangered species by the International Union for the Conservation of Nature’s Species Survival Commission.
Sauther has been conducting research on Madagascar for 25 years, beginning as a University of Washington graduate student. Today she has several CU-Boulder doctoral students working with her, including James Millette, who is studying how the tooth wear of lemurs relates to their foraging behaviors.
“Madagascar is a challenging place to conduct research,” Millette said. “Part of our job is to work with local communities, because without the support of these people there would be no lemur conservation. We consider Beza, where we have been working with the community for several decades, to be a real success story.”

Feed them and they will die!
Nov 27th
In recent years, bears have become more reliant on trash as a food source. By leaving their natural habitat to scavenge for food, bears are unintentionally putting themselves in danger. Securing trash and compost storage will help protect bears, increase public safety, and allow bears and humans to better co-exist.
The City of Boulder is asking for the community’s input on options to make food waste less accessible to bears. Community members are encouraged to complete a survey at www.surveymonkey.com/s/bears-trash to help evaluate potential options for the location, storage and enforcement of trash regulations.
The city will also host a public meeting from 5 to 7:30 p.m. on Monday, Dec. 9, in the West Senior Center (909 Arapahoe Ave.) to get community input on options for securing trash in Boulder.
At its Oct. 15, 2013, meeting, City Council received a staff update on bears and trash in the urban interface. This update was, in part, due to community and council concern related to four bears that were killed by Colorado Parks and Wildlife because of public safety concerns.
At the meeting, council identified securing trash from bears as a priority and staff committed to developing options that will be presented for consideration in early 2014. The community’s input will help shape the options delivered to City Council in January 2014.
