Trees in the Tundra
At the southern edge of the Arctic,
in Canada’s Hudson Bay lowlands, lies Churchill, Manitoba – a small town that
sits at the convergence of tundra, forest, freshwater, and marine ecosystems.
Also known as the “polar capital of the world”, Churchill is located at the
Arctic treeline, and is extremely sensitive to small environmental changes that
have a huge impact on ecosystems.
Earthwatch scientists LeeAnn Fishback
and Steve Mamet lead the expedition Climate Change at the Arctic’s Edge
to shed light on increasingly important issues like the melting of permafrost,
wetland dynamics, and a shifting treeline. Find out more about their research
in our multimedia feature story.
