BC's Inland Temperate Rainforest

Canada’s forgotten rainforest, the only one of its kind.

The Inland Temperate Rainforest (ITR) ecosystem covers 40 million acres, and stretches 700 miles in a broad arc from central Idaho to Prince George, British Columbia, encompassing a globally unique, rich and diverse landscape. This ecosystem is the last inland rainforest left on earth that is somewhat intact.

In this globally unique ecosystem the wet and super wet cedar-hemlock forests are the prime jewel. These forests contain species that are new to science and these forests harbour an amazing diversity of rare plants, animals, and fungi. This region is home to deep snow caribou which are a unique ecotype of mountain caribou which have evolved to live in the deep snows and old growth forests of the Inland Temperate Rainforest region. These wet cedar-hemlock forests primarily occur from the Goat Range, Nakusp and Trout Lake, Central Monashees areas, north into the Revelstoke, Mica, Seymour, and Adams River areas, Caribou Mountains, and the upper Fraser watershed. Historically the vast majority of these forests in this ecosystem were ancient old growth. Today the vast majority of these forests have been converted into young forests primarily through logging.


500 kilometres from the coast, the ITR is disappearing unnoticed.

The Inland Temperate Rainforest is under threat. Due to logging there is nearly 3 times more young forest in the Revelstoke-Shuswap than under historic natural disturbance regimes. At a provincial scale, only three percent of the productive low elevation old growth that grows large trees remains. The vast majority of these productive old growth forests are slated to be logged in the near future.

Thousands of hectares of globally unique forests are cut every year in the Inland Rainforest. This drastic ecosystem change has put sensitive species like mountain caribou on the brink of extinction. The provincial population of deep snow dwelling mountain caribou is down to approximately 1200 caribou. The Revelstoke area is thought to be one of the strongholds with the Columbia-North subpopulation stable at 184 caribou (2021 provincial estimate). The Columbia-North range starts near Downey Creek on the Eastside and in the Anstey Range on the Westside of the Columbia and extends into the Northern Monashees, Northern Selkirks, and Rockies. Environment Canada projects that 2000 hectares (3500 soccer fields worth of forest) of caribou habitat is logged every year in the Revelstoke and Shuswap region. The vast majority of this logging is old growth.


Critical for climate.

These Cedar Hemlock rainforests are incredibly important for carbon. These forests play a critical role in carbon storage and sequestration. One UNBC study from the Inland Temperate Rainforest (ITR) in the Robson Valley found that total forest carbon storage in ITR forests was similar to Coastal rainforests, which are considered to be amongst the most carbon rich forests in the world. The study also found that, once clearcut, these forests lose nearly 4/5th of their carbon. Much of that carbon is stored in living trees but also large downed trees, and soils which are disturbed or removed once logged. The Inland Temperate Rainforest is a potential carbon sanctuary, and in the age of a rapidly changing climate, deserves protection simply on that basis.

Beyond carbon, the Inland Rainforest’s old growth is critical for water, for caribou, flying squirrels, bull-trout, lichens, birds, and us. The old growth forests of the Inland Temperate Rainforest are non-renewable because they have taken hundreds, if not thousands of years to develop, and these forests often produce their own unique micro climates. As the research of Dr. Suzanne Simard’s research shows, in these primary forests, there’s complex partnerships happening among all of the forest parts: there’s competition, there’s negotiation, and there’s symbiotic relationship among trees, plants, and fungi which form partnerships to help share water and nutrients. You can remove some of the parts of a forest and it will survive, unfortunately much of the logging and forestry we do in BC removes all of the parts.

Old growth forests are worth more standing than they are logged. The Inland Temperate Rainforest deserves protection and for far too long these forests have only been valued for timber production. It’s time for some leadership from the province. It’s time for our ecosystems to be valued, it’s time to stop logging our old and nonrenewable globally unique forests.

How you can help


Join our campaign to end old growth logging in the ITR. Speak up today – let the BC Government know it is vital that immediate action is taken to prevent imminent ecological collapse in the Inland Temperate Rainforest.

Your gift towards our conservation efforts will create meaningful change for wildlife and wild places in remarkable places like the Inland Temperate Rainforest.
