File:Spring In The Canadian Arctic.jpg
With access to constant light, flowing water, and warmer temperatures, plants are beginning to grow. The land around the Mackenzie River has a deep green hue. The line between tundra and forest runs through this image. The forest is dark green, while the tundra is still brown.
The land also shows the first sign of summer: large forest fires. One large forest fire is outlined in red. Smoke from nearby fires flows across the lower left corner of the image. The boreal forest needs fire to maintain the ecosystem, and large fires happen regularly in the summer. In the remote region shown here, lightning ignites most forest fires.
