Canada's Yellowstone too small for wildlife

07.07.2006
A new scientific report by the Wildlife Conservation Society, a 110-year-old science-based conservation organization, says that Northwest Territories' Nahanni National Park Reserve – one of Canada's most beloved and storied national parks – is too small to maintain its nearly pristine population of grizzly bears, caribou and Dall's sheep.

According to the report, which looked at more than four years of WCS field data, the park needs to expand from its current size of under 5,000 square kilometers, to include the entire South Nahanni River watershed and the adjacent Nahanni Karstlands, an area totaling more than 38,000 square kilometers – four times larger than Yellowstone National Park.

The report's author, Dr. John Weaver of the Wildlife Conservation Society, said that the park's current narrow boundaries are too small to contain grizzlies, caribou and Dall's sheep, all of which occupy much larger ranges than the park currently provides. He cautions that without expanding the boundaries, these species will decline due to development pressures looming outside of the park.

"Unfortunately, wildlife do not recognize park boundaries, and this is particularly true in the case of Nahanni National Park Reserve" said Weaver, who has studied North American wildlife for more than three decades. "If we don't protect the full range of Nahanni's populations of grizzlies, caribou, and Dall's sheep, then those species are in trouble."

Weaver's research showed that the Nahanni's woodland caribou, for example, frequently travel over long distances outside of the park, and need unbroken boreal wilderness to survive. Currently, key seasonal areas for caribou lie outside of the park.

Nahanni's grizzly bear population, according to the report, contains some of the highest genetic diversity of any other grizzly population in North America, revealing a nearly pristine population of these large carnivores. Weaver also discovered new populations of Dall's sheep during his field research that feed in a unique habitat – lush grasses outside of a concentration of karst caves found no where else on the continent. But again, the area lies outside of the current national park. (more)

"We welcome the release of this study by John Weaver who is internationally respected as a wildlife biologist," says Daryl Sexsmith, executive director of the Canadian Parks and Wilderness Society's (CPAWS) NWT chapter. CPAWS has been advocating for expansion of the Nahanni National Park Reserve to protect the entire South Nahanni watershed for the past five years, working closely with the local Dehcho First Nations.

Besides the unique concentration of karst caves, the region also contains the deepest river canyons anywhere in Canada, which resemble sections of the Grand Canyon. It also contains large hot-springs mounds that are similar to Mammoth Hot Springs in Yellowstone National Park. And Virginia Falls in the center of the Park Reserve are twice as high as Niagara Falls. The United Nations (UNESCO) recognized Nahanni National Park Reserve as the first World Heritage Site.

Yet, according to the report, major industrial developments across the Mackenzie River basin, including oil and gas development and mining, are imminent, so the need to address the problem of the Park's inadequate boundaries is now.

"Canada has a unique opportunity to create one of the largest and most wild national parks in the world," said Weaver.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
