FRISCO — The tiny ice-free fringes of Antarctica are especially prone to ecosystem disruption, including invasive species, an Australian science team warned earlier this year after taking a close look at how human use is concentrated in those slivers of dry land.
Antarctica has over 40,000 visitors a year, and more and more research facilities are being built in the continent’s tiny ice-free area. Most of the Antarctic wildlife and plants live in the ice-free areas – and this is also where people most visit.
Most tour operators in Antarctica follow strict guidelines set to protect ecosystems, including at least basic decontamination procedures, but those measures might not be enough, especially as global warming makes ice-free zones more susceptible to invasive species. Continue reading

Study shows costs of coastal litter

FRISCO —Littered beaches are a costly economic liability in California, as beach-goers tend to avoid local beaches if they’re dirty. The economic study, funded by NOAA’s Marine Debris Program, showed that having no marine debris on the beach and good water quality were the two most important factors in deciding which beach to go to.
Given the enormous popularity of beach recreation throughout the United States, the magnitude of recreational economic losses associated with marine debris has the potential to be substantial. Continue reading

“The bottom line is that the scale of the proposed development, more than 20,000 hotel rooms, is completely disconnected from the ecology of this desert region”

FRISCO — A proposed 20,000-room resort development in Baja California Sur threatens a high value conservation area that’s important for hundreds of plants and animals, including 42 birds recognized as endangered species under Mexican law.
Government officials are slated to make a decision on the Cabo Dorado development proposal next month, and the scientists who recently surveyed the area said there’s no way the project should be built in anywhere near its present configuration.
“Until recently, the biological value of the lands adjacent to the coral reef of Cabo Pulmo had remained a mystery,” said University of California, Riverside’s Benjamin Wilder, referring to the Cabo Pulmo reef, which has rebounded from over-fishing in recent years. Continue reading

Government dysfunction hurts gateway towns near parks

FRISCO — Visits to National Parks in the U.S. fell slightly in 2013, mainly due to the government shutdown in October, when the National Park Service turned away millions of visitors.
In total, 273.6 million total visits were recorded during the year at the 401 parks, down 9.1 million visits from 2012. The shutdown also resulted in an estimated loss of $414 million in visitor spending in gateway and local communities across the country when comparing October 2013 to a three-year average (October 2010-12).

‘The San Antonio Missions represents a vital part of our nation’s Latino heritage …’
By Summit Voice
FRISCO — It’s been nearly 20 years since a new World Heritage site has been designated in the U.S. but that could soon change. Secretary of the Interior Sally Jewell last week said the San Antonio Missions, including the Alamo, will be nominated for the international list, which recognizes the most significant cultural and natural sites on the planet.
The most recent U.S. addition to the World Heritage register was the Waterton-Glacier International Peace Park (administered jointly with Canada) in 1995.
“World Heritage Sites represent an incredible opportunity for the United States to tell the world the whole story of America and the remarkable diversity of our people and beauty of our land,” Jewell said. “The San Antonio Missions represents a vital part of our nation’s Latino heritage and the contributions of Latinos to the building of our country.” Continue reading

Study shows how human food affects rare rock iguanas
By Summit Voice
FRISCO — There are plenty of good reasons to follow the old adage about not feeding wild animals, and a recent study of endangered Bahamian rock iguanas provides even more proof.
According to the findings, tourist-fed iguanas are suffering physiological problems as a result of eating human food. In the study, led by Charles Knapp of the John G. Shedd Aquarium in Chicago, the scientists compared blood and faecal samples from iguanas that were fed by tourists to samples from iguanas that did not have any interactions with humans.
The body condition of the two groups of iguanas was similar, but indicators for dietary indicators showed the effects of feeding by humans. Both male and female iguanas from the islands frequently visited by tourists showed notably different levels of glucose, potassium, and uric acid, as well as levels of other minerals. The female iguanas from tourist areas differed significantly in ionized calcium. Continue reading

wolf population across the 6 million acre park and preserve declined from 143 in fall 2007 to just 55 in spring 2013
By Bob Berwyn
FRISCO — An arbitrary decision by the Alaska Board of Game to allow wolf hunting and trapping near Denali National Park has cut the regional wolf population by nearly two-thirds and significantly reduced opportunities for park visitors to see wolves in the wild — one of the main reasons people go to Denali in the first place.
This year, fewer than 5 percent of park visitors were able to see wolves, down from about 45 percent back in 2000, according to National Park Service statistics obtained by a federal government watchdog group.
“This precipitous decline in wildlife viewing success appears to be unprecedented in the history of the national park system,” said Rick Steiner, a retired University of Alaska professor and a Public Employees for Environmental Responsibility board member. Continue reading
