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.

Climate change: Big changes for big mammals
Jan 23rd
in mammal responses to climate change
If you were a shrew snuffling around a North American forest, you would be 27 times less likely to respond to climate change than if you were a moose grazing nearby.
That is just one of the findings of a new University of Colorado Boulder assessment led by Assistant Professor Christy McCain that looked at more than 1,000 different scientific studies on North American mammal responses to human-caused climate change. The CU-Boulder team eventually selected 140 scientific papers containing population responses from 73 North American mammal species for their analysis.
The studies assessed by the team examined seven different responses to climate change by individual mammal species: local extinctions of species known as extirpations, range contractions, range shifts, changes in abundance, seasonal responses, body size and genetic diversity. The researchers used statistical models to uncover whether the responses of the 73 mammals to a changing climate were related to aspects of their physiology and behavior or the location of the study population.
The analysis showed only 52 percent of the mammal species responded as expected to climate change, while 7 percent responded the opposite of expectations and the remaining 41 percent had no detectable response. The two main traits tied to climate change responses in the CU-Boulder study were large mammal body size and restricted times during a 24-hour day when particular mammal species are active, she said.
A paper on the study by McCain and former CU-Boulder postdoctoral fellow Sarah King was published online Jan. 22 in the journal Global Change Biology. The National Science Foundation funded the study. King is currently a research associate at Colorado State University.
While body size was by far the best predictor for response to climate change — almost all of the largest mammals responded negatively — the new study also showed that mammals active only during the day or only at night were twice as likely to respond to climate change as mammals that had flexible activity times, she said.
“This is the first time anyone has identified specific traits that tell us which mammals are responding to climate change and which are not,” said McCain of CU-Boulder’s ecology and evolutionary biology department.
McCain said she and King were surprised by some of the findings. “Overall the study suggests our large, charismatic fauna — animals like foxes, elk, reindeer and bighorn sheep — may be at more risk from climate change,” she said. “The thinking that all animals will respond similarly and uniformly to temperature change is clearly not the case.”
The researchers also found that species with higher latitudinal and elevation ranges, like polar bears, American pikas and shadow chipmunks, were more likely to respond to climate change than mammals living lower in latitude and elevation. The ability of mammals to hibernate, burrow and nest was not a good predictor of whether a species responded to climate change or not. American pikas have been extirpated from some of their previously occupied sites in the West, as have shadow chipmunks, which are in decline in California’s Yosemite National Park.
One of the most intriguing study findings was that some small mammals may shelter from climate change by using a wider array of “micro-climates” available in the vegetation and soil, she said. McCain compared the findings with the events at the K-T boundary 66 million years ago when an asteroid smacked Earth, drastically changing the climate and killing off the big dinosaurs but sparing many of the small mammals that found suitable shelter underground to protect them from the cataclysmic event.
“I think the most fascinating thing about our study is that there may be certain traits like body size and activity behaviors that allow some smaller mammals to expand the range of temperature and humidity available to them,” said McCain, also a curator of vertebrate zoology at the University of Colorado Museum of Natural History. “These areas and conditions are not available to bigger mammals that live above the vegetation and experience only ambient temperatures.”
The new study builds on a growing body of global information documenting the shifting behaviors and environments of organisms like flowers, butterflies and birds in response to a warming world, said McCain.
“If we can determine which mammals are responding to climate change and the ones that are at risk of disappearing, then we can tailor conservation efforts more toward those individual species,” said McCain. “Hopefully, this potential loss or decline of our national iconic mammals will spur more people to curb climate impacts by reducing overuse of fossil fuels.”
