World Wildlife Fund Report Shows Federal Protection Isn't Saving Canada's Animals

  World Wildlife Fund Report Shows Federal Protection Isn't Saving Canada's Animals World Wildlife Fund Report Shows Federal Protection Isn't Saving Canada's AnimalsDeclining species lost a total of 83 per cent of their numbers between 1970 and 2014, says the report released Thursday by the World Wildlife Fund. Species protected by federal legislation shrank nearly as quickly as those that weren't.

In fact, species listed under Canada ' s Species at Risk Act (SARA) have declined even more quickly on an annual basis since the legislation was adopted 2002, according to The Living Planet Report Canada Top News Headlines. Canada ' s threatened species declining despite federal protection .

From woodland caribou to St. Lawrence beluga whales, Canada's threatened and endangered species keep declining despite federal legislation designed to protect them and help their populations recover, a new report by WWF-Canada shows.

In fact, species listed under Canada's Species at Risk Act (SARA)  have declined even more quickly on an annual basis since the legislation was adopted 2002, according to The Living Planet Report Canada, set to be released Thursday morning by the conservation group.

Half of all Canadian species are in sharp decline

But a startling new study suggests the country's abundant fauna are in increasing trouble.

Despite the Alberta Wildlife Act’ s designation of the woodland caribou as a threatened species their populations continue to decline faced with A news report today highlights information from a report prepared by Environment Canada for the federal government in relation to the legal challenges.

"I think that's troublesome in terms of whether it's indicative of the relative success of the federal program for the recovery of species at risk," said James Snider, vice-president for science research and innovation at WWF-Canada and the lead author of the report.

The report analyzed publicly available population data from places like scientific databases and journals for 903 mammal, bird, reptile, amphibian and fish species in Canada. WWF-Canada used a peer-reviewed method developed by the London Zoological Society that is also used by the WWF to create global reports on vertebrate population trends every two years.

The analysis shows that 451 — half the species in the study — declined in number between 1970 and 2014. Snider said that was a surprise.

"Frankly, as a Canadian, I think we all pride ourselves in the relative wilderness," he said, "and we almost have an assumption … that most of our wildlife would be doing well."

On average, the species that were declining lost 83 per cent of their Canadian population during the study period. Declines were seen in species across the country, but grassland species such as bobolinks, along with shorebirds and aerial insectivores like swallows showed some of the sharpest declines.

The report suggests habitat loss due to human activity such as farming — the main problem in the grasslands —  forestry, urban and industrial development is a major cause, along with climate change, invasive species and overfishing.

The 87 species in the study protected under the SARA declined by 63 per cent over the study period. Their populations shrank an average of 2.7 per cent per year after SARA was enacted, up from 1.7 per cent a year before 2002.

Scientists sniff out Thailand's first truffle species

  Scientists sniff out Thailand's first truffle species Gastronomes of the world delight. Two new types of truffle have been unearthed in Thailand's far north, scientists announced Thursday in what they called a first for Southeast Asia. Researchers at Chiang Mai university said they had identified two brand new species and confirmed that tuber magnatum -- the same species as Italy's much sought after white truffle -- had been found in a national park surrounding Mount Suthep in northwestern Thailand.

Although federal protection made it illegal to harm desert tortoises or remove them from the wild of the southwestern North American deserts, this measure has been insufficient to reverse the species ’ decline , and further intervention is required.

"According to researchers, the federal Species at Risk Act has faltered in its mission to protect Canada's most beleaguered wildlife," the report says.

David Miller, president and CEO of WWF Canada, told CBC News: "The lesson we take from this is we need to act before species get identified as endangered, because it's so hard to turn around populations once they're deteriorated that far along the scale."

Delays in protection

One reason species decline despite being protected by SARA is that, in many cases, the government takes a long time to decide whether to accept a scientific recommendation to list a species, and there are further long delays between listing a species and actually taking action, the WWF says.

For example, the woodland caribou was listed as threatened in 2003, but its "recovery strategy" wasn't released until 2012. "During this time, development activities continued to damage key woodland caribou habitat," the report says. It adds that actual action plans to help the woodland caribou recover aren't due from the provinces and territories until the end of 2017.

'Extinct' giant tortoise to be bred in captivity

  'Extinct' giant tortoise to be bred in captivity A species of Galapagos giant tortoise thought to have been made extinct 150 years ago will be bred in captivity, officials said, after DNA studies showed specimens discovered in the last decade shared similar genetic makeup.  The breeding program involving 32 tortoises -- 19 of which are descended from the Chelonoidis nigra species in question -- will allow for medium-term repopulation of their native Floreana Island, the Galapagos Islands National Park said Wednesday.

The WWF's Canadian study, the first since 2007, took two years and cost hundreds of thousands of dollars, Miller said.

Snider said the goal was to look for trends to see how different groups of species, ecosystems and regions of the country were faring across Canada, in part to help the WWF determine where conservation efforts are most urgently needed.

The report notes there were some big gaps in the data for regions such as freshwater ecosystems and the Arctic. "As a result, we lack sufficient data to answer key questions about the status of wildlife and to track and evaluate trends over time," it said. It recommends collecting more data to track biodiversity across the country.

The WWF recommends a number of other actions by governments, businesses and the public to help reduce the loss of wildlife such as:

- Doing more research on how wildlife are impacted by and responding to climate change.

- Doing a better job of implementing SARA, including focusing on protecting ecosystems rather than individual species.

- Expanding Canada's network of protected areas.

Philip McLoughlin, a population ecologist at the University of Saskatchewan, studies large mammals in Canada, including woodland caribou in northern Saskatchewan.

He thinks establishing an index to monitor Canada's wildlife is a "really good idea" that will allow us to look back in 20 or 30 years to see if and how things have improved.

"And being able to have the data and people consciously collecting data for an index like this, I think this bodes well," he said.

He added that the report is "bang on in terms of the challenge we have in such a large country to protect species at risk."

Julia Baum, a marine biologist at the University of Victoria who has just completed a study of population trends among marine fish in Canada, said she'd be interested in seeing the data used in the index. Her analysis shows marine fishes are doing "a lot worse" than they appear to be doing in the report.

The way the report groups species together can obscure important details, as species that are increasing can cancel out those that are declining, she notes.

"On one hand, it's great to have report like this, that gives us this comprehensive, wide-ranging, high-level view of what's the status of wildlife in Canada," said Baum. But she's now more interested in looking for ways to rebuild populations.

"We have to quit focusing on writing these obituaries for nature," she added. "Because what we really need is to start problem solving."

Evidence of 'night parrot', one of world's rarest birds, found in Australia .
A feather from one of the most elusive birds in the world has been found in South Australia, the first proof in more than a century that it lives there, wildlife experts said Thursday. The "night parrot" ranks among the world's rarest avian species and was thought extinct until an intrepid Australian naturalist provided photo evidence of one in Queensland state in 2013.
