Canada’s role in global biodiversi­ty conservati­on

As a northern nation that was mostly covered by glaciers only 10,000 years ago, Canada has fewer species than tropical countries where the evolution and emergence of new species has been operating in stable environmen­ts for hundreds of thousands of years. Tiny Panama has 10 times more tree species than Canada. Brazil has hundreds of more species on the IUCN Red List of Threatened Species compared to Canada.

Protecting the diversity of species on planet Earth is critical for conservati­on, and future generation­s should judge us on the number that we knowingly discard from our global menagerie. Sumatran tigers and Cuban parakeets are important to save, and so is the Yukon grasshoppe­r and the more than 500 other globally rare species that live in Canada.

What has become increasing­ly clear is that nature conservati­on must not only focus on areas with high numbers of different species; successful conservati­on also requires the protection of large, intact ecosystems. A 2016 study found that the area of intact wilderness landscapes has shrunk to just 23 per cent of the planet, and has declined by 10 per cent since 1990.

This is where Canada can truly play a global leadership role in conservati­on. We live in a country where our own conservati­on decisions matter to the world.

Here are four key facts that every Canadian should know about our country, and why Canada is an important force for global conservati­on.

1. The world’s largest area of intact forest landscapes are here Canada, in the vast stretch of spruce, fir and birch that extends from Newfoundla­nd and Labrador to Yukon. More than onethird of the Canadian land base (3.47 million square kilometres) is covered with trees. While Canada ranks third for total forest cover (behind Brazil and Russia), we have more intact forest than any other country.

2. Canada has one-quarter of the wetlands remaining on Earth. In a world that has lost an estimated that 64 per cent of its wetlands since 1900, Canada has an unparallel­ed abundance of this important ecosystem. Canadian wetlands are very diverse and range from vast forested peatlands in the boreal, to marshes and deltas in freshwater lakes to prairie potholes. Canada has approximat­ely 25 per cent of the world’s wetlands by area, and wetlands cover approximat­ely 1.5 million square kilometres of our county (equivalent to more than twice the size of France).

3. Canada has more freshwater lakes than all other nations combined

Canada has 60 per cent of all freshwater lakes in the world, more than all other nations combined. This includes more than 560 lakes that are larger than 100 square kilometres. In total, there are approximat­ely two million lakes, and fresh water covers approximat­ely nine per cent of our country.

4. Canada has the longest marine coast in the world

Canada’s marine coasts measure more than 243,000 kilometres in length. This is the longest coast of any country in the world, and exceeds the combined coastal length of Japan, Indonesia, Australia, United States, Norway and Russia. Much of our northern coast in the Arctic is still wild and remote.

Within these places are extraordin­ary wildlife. We live in a country that has more polar bears, narwhals, lake trout, caribou, Harris’s sparrows, jack pine and hundreds of other species than anywhere else on the planet. There are places such as the Nature Conservanc­y of Canada’s Johnson’s Mills Shorebird Reserve and Oak Lake/ Plum Lake property where Canadians can still observe the awesome spectacle of wildlife abundance. In a world that is rapidly losing wildlife, Canada has an opportunit­y to conserve and restore nature’s abundance, an opportunit­y that has slipped away from much of our planet.

Nature is a defining feature of Canada. Our vast, northern geography has shaped our economy, society and Canadian identity. As we mark the 150th birthday of Canada, all of us should know what makes our nation unique, our opportunit­y for global leadership in conservati­on and our obligation to future generation­s of Canadians.
