New interior secretary begins stint by re-authorizing use of toxic lead hunting ammunition

Let them eat lead …

Staff Report

Toxic lead is back on the menu for many wildlife species, as newly appointed  Interior Secretary Ryan Zinke revoked a U.S. Fish and Wildlife Service order that had banned lead hunting ammunition on federal wildlife reserves after a years-long campaign by wildlife advocates.

The USFWS order was finalized the day before Donald Trump was inaugurated as president. In his reversal, Zinke made no reference to the extensive body of science showing that lead ammunition is harmful to wildlife.

His first move as Interior Secretary should make it clear that anybody who had been hoping Zinke would be a reasonable voice in the new anti-environment administration was sorely mistaken. Along with the rest of Trump’s cabinet picks, Zinke seems likely to move ahead at full speed in dismantling as many environmental protections as possible.

Study says road threat to carnivores is underestimated globally

Findings to help guide conservation strategies

Staff Report

The threat of roads to carnivore species around the world has been seriously underestimated, according to a new study that looked at the issue on a global scale.

After looking at 232 carnivore species around the world (out of a total of about. 270 existing species) and assessing how severely these are affected by roads cut through their habitat, the researchers concluded that some rare species are even at risk in areas with low road densities. The study, published in the journal Global Ecology and Biogeography, calculated natural mortality rates, reproduction and carnivore movement patterns, determining the maximum density of roads that a species can cope with.

Wildlife: Jackals spreading into central Europe

Changing climate, shifting species

Staff Report

Climate change and other impacts from human activities are enabling jackals to spread into parts of Europe, scientists said after documenting the first living golden jackal in the Czech Republic. The mammal, native to northern Africa and southern Eurasia, was photographed by motion sensors cameras several times just 40 kilometers from Prague, according to a new study published in the open access journal ZooKeys.

“The habitat, where the golden jackal decided to settle, resembles the landscapes which these animals prefer in their natural distribution area, the Balkans – an open grass-shrubland surrounded by a forest. It is one of the warmest areas in the country, with mild winters.The observed animal was mostly active at dusk and dawn, with majority of the sightings occurring in the morning hours,” said researcher Klára Pyšková, who co-authored the paper with  a group of researchers from Charles University and Institute of Botany of the Czech Academy of Sciences, among them her supervisors Ivan Horáček and David Storch.

Draft plan for jaguar recovery panned by wildlife advocates

Jaguars listed as endangered since 1997

Staff Report

Jaguars making their from Mexico back to the southwestern U.S. apparently won’t be getting much help from the U.S. Fish and Wildlife Service. The agency this week released a draft recovery plan that puts the conservation burden on Mexico. The plan’s criteria for recovery and removal of the jaguar from the “endangered” list could be met without any jaguars occupying any of their vast historic range in the United States, according to wildlife watchdogs with the Center for Biological Diversity.

The draft was released just a short time after a second jaguar was documented in the Southwest. Between 2011 and 2015, another jaguar was seen several times around the Santa Rita Mountains southeast of Tucson. Another jaguar called “Macho B” was photographed repeatedly from 1996 until he was killed by the Arizona Department of Game and Fish as a result of a botched capture operation in 2009.

“Jaguars are making their presence known in the southwestern United States so it’s disappointing to see the U.S. Fish and Wildlife Service put the focus of jaguar recovery solely in Mexico,” said Michael Robinson of the Center for Biological Diversity. “By excluding the best remaining unoccupied jaguar habitat, this plan aims too low to make a difference in saving the jaguar. It’s an extinction plan, not a recovery plan.” Continue reading “Draft plan for jaguar recovery panned by wildlife advocates”

Snake-killing fungus is widespread in the East

Some snake populations appear at-risk from spreading fungal pathogen

Staff Report

First the chytrid fungus started killing amphibians, then white-nose syndrome emerged to devastate bat populations, and now, there’s Ophidiomyces ophiodiicola, a snake-killing fungus that appears to be much more widespread than thought, according to new research from the U.S. Geological Survey.

The USGS report concluded the fungus is present in at least 20 eastern states and in many snake species not previously known to  harbor the fungus. These findings increase the total number of confirmed susceptible snake species to 30. Snakes affected by Snake Fungal Disease include the threatened eastern massasauga rattlesnake. The research also shows that SFD infections are often mild, but there are unknown factors that cause outbreaks of severe skin disease and death.

For the third time in ten years, a judge orders the U.S. Fish and Wildlife Service to consider critical habitat for lynx in Colorado

‘The Service’s own representations suggest that parts of Colorado constitute suitable critical habitat, appropriate for designation’

Staff Report

A federal judge in Montana has once again ruled that the U.S. Fish and Wildlife Service violated the Endangered Species Act when it excluded Colorado from a critical habitat designation for threatened lynx. In the end, the rare cat may yet get some protected sanctuaries in the Colorado high county.

In a Sept. 7 ruling, Chief District Judge Dana L. Christensen said the agency’s decision is arbitrary and capricious, and “offends the ESA.” The court ordered the USFWS to develop a new critical habitat designation that complies with the law. The order also covers parts of Montana and Idaho.

Environment: Massive fish kill reported in Yellowstone River

A Colorado Division of Wildlife biologist holds a young rainbow trout before releasing it into the Blue River in Silverthorne. The fingerling was raised in a cross-breeding program to develop a strain of fish resistant to parasitic whirling disease that all but wiped out rainbow trout across parts of the West.

Staff Report

The Yellowstone River, part of Montana’s iconic western landscape, is once again beset by environmental woes, as a rapidly spreading fish kill has spurred state resource managers to close the river to all recreational uses, including fishing, boating and tubing. Biologists with Montana Fish, Wildlife and Parks said they’ve counted more than 2,000  dead mountain whitefish, and the estimate the total mortality in the tens of thousands. The river was also hammered by an oilspill in 2011 after pipeline burst. Continue reading “Environment: Massive fish kill reported in Yellowstone River”
