Ashland, OR —The Government of British Columbia must take urgent and immediate action to protect the globally unique ecological values of BC’s remaining primary and intact coastal and inland temperate rainforest, say 223 prominent scientists from around the world in a letter released today.

The scientists specifically call for action to protect temperate rainforests along BC’s south coast and Vancouver Island, and inland rainforests on the windward side of the Columbia and Rocky Mountains, all of which remain at risk with insufficient conservation.

The letter was organized by Dr. Dominick DellaSala, chief scientist at the Geos Institute in Ashland, Oregon and author of Temperate and Boreal Rainforests of the World: Ecology and Conservation (Island Press). According to DellaSala, “BC’s temperate rainforests are globally rare, they offer habitat for many imperiled species and globally the vast majority of these unique rainforests has already been logged. Protection of remaining intact tracts of these carbon-rich, climate saving forests is a global responsibility and can help Canada to contribute to the 2020 UN biodiversity targets and the Paris Climate Agreement.” Recently, the ninth largest Douglas-fir in Canada was cut down in the Nahmint Valley near Port Alberni. The tree, which was 66 metres tall and three metres in diameter, was in an old-growth cut block auctioned off by the BC government. 

Temperate rainforests are rare, constituting just 2.5 per cent of the earth’s forests. British Columbia is home to one quarter of that total and BC’s inland rainforests are one of only two such areas worldwide.

“It is hard to overstate the cultural significance of these rainforests to the Indigenous peoples who have inhabited this part of the world for millennia,” said Dr. Barbara Zimmerman, Director of the International Conservation Fund Canada. “Their loss would be an enormous blow to all Canadians and all people of the world. Destruction of the last remnants of ancient old-growth forest with their magnificent trees and complex web of life is a rapidly unfolding tragedy and the vast majority of Canadians are unaware that it is even happening.”

According to recent estimates by Sierra Club BC, logging of old-growth temperate rainforest is currently destroying 10,000 hectares per year on Vancouver Island—the equivalent of two soccer fields per hour, 24 hours per day. Productive old-growth rainforests in lower elevations have been reduced to less than 10 per cent of their original extent. Plants and animals that depend on these rainforests are not just losing habitat, but also are suffering climate change impacts such as extended droughts, extreme rainfall and severe storms, threatening to push ecosystems to limits. Similar losses are occurring in the inland rainforest region where logging of old-growth rainforest has been extensive and is contributing to the demise of mountain caribou.

“BC has inspired the world with conservation solutions in Haida Gwaii and the Great Bear Rainforest. The province should take similar action to safeguard what remains of these globally outstanding ancient forests in other parts of the province,” said BC forest ecologist Andy MacKinnon. “The provincial government should follow through on its promise and take action for old-growth conservation using the same model and its multiple benefits for biodiversity, communities and the climate.”

Forests absorb atmospheric carbon through the process of photosynthesis and store it in long-lived plants and soils. In doing so, they help to cool down the planet. Cutting down forests releases most of their stored carbon as a global warming pollutant.

The experts are urging the provincial government to follow through on the promise to use the ecosystem-based management approach implemented in the Great Bear Rainforest to safeguard British Columbia’s endangered old-growth rainforest.

The signatories to the letter live and work in many countries, including Argentina, Australia, Canada, Indonesia, Mexico, Mongolia, Norway, the United States and Scotland.

Scientists speak out for Tongass roadless and old growth protections

ASHLAND, OR - 220 leading scientists, researchers, and university professors spoke out in unison today in support of protecting the Tongass National Forest from rollbacks to roadless area and old-growth forest protections proposed by Alaska Sen. Lisa Murkowski (attached letter).

Dr. Dominick A. DellaSala, Chief Scientist of the Ashland-based Geos Institute, author of "temperate and boreal rainforests of the world: ecology and conservation," and co-author of the scientist letter, said "The Tongass is the crown jewel of the national forest system and one of the world's last remaining intact temperate rainforests. Alaska is on the front lines of climate impacts from melting glaciers, rapid thawing of permafrost, and rising temperatures. It makes no sense to open up old growth logging wounds when the Forest Service can be transitioning to more climate friendly young forest logging."

DellaSala added, When old-growth rainforests are cut down up to two-thirds of their stored carbon is released to the atmosphere as a global warming pollutant. Old-growth logging on the Tongass is estimated to release the carbon dioxide equivalent of adding over 2 million vehicles per year to Alaska's climate impacts (See:

The Tongass is the only national forest still clearcutting old-growth forests. Most have moved on to logging smaller less controversial trees.

A new global map of roadless areas shows that the Earth’s surface is shattered by roads into more than 600,000 fragments. More than half of them are smaller than 1 km2. Roads have made it possible for humans to access almost every region but this comes at a very high cost ecologically to the planet’s natural world. Roads severely reduce the ability of ecosystems to function effectively and to provide us with vital services for our survival. Despite substantial efforts to conserve the world’s natural heritage, large tracts of valuable roadless areas remain unprotected. The study shows that the United Nations’ sustainability agenda fails to recognize the relevance of roadless areas in meetings its goals.

TUCSON, Ariz.— A new study published in the scientific journal Ecosphere finds that public forests that are protected from logging burn less severely than logged forests. The study is the most comprehensive investigation of its kind, spanning more than 23 million acres and examining three decades’ of forest fire data in the West. Among the major findings were that areas undisturbed by logging experienced significantly less intensive fire compared with areas that have been logged.

Obama Administration Should Protect Tongass National Forest Old Growth To Achieve Urgent Climate Change Goals

For Immediate Release on June 30, 2016

– Tongass Logging Plan Ignores Fast Exit from Old-growth Logging

– Agency Relies on Old School Forestry Tactics

– Contradicts Secretary of State John Kerry’s and President Obama’s Climate Statements

Ashland, OR – The release of the Forest Service’s old-growth logging plan (Final Environmental Impact Statement) for the Tongass National Forest stalls urgent climate change protections and runs counter to the Obama administration’s climate change directives. The plan contradicts the US-led Paris Climate Change Agreement that includes measures to protect vast amounts of carbon stored in forests to help head off dangerous global warming. The Forest Service’s plan calls for continued logging of old growth trees for another 16 years, which threatens 43,000 acres of Tongass old-growth rainforest. The unnecessarily long timeframe will release the equivalent emissions of 4 million vehicles annually over the next 100 years at a time when nations are looking to cut back on emissions.
