Is the boreal forest prone to wildfires?

The boreal forest is adapted to fire. Fires create a variety of landscapes, or mosaic, with young and old trees living on the landscape. In central Alaska, the spruce forest usually burns every 60 years to 150 years. Fires help remove the thick forest floor mat of old forests so that new young forests can begin.

Two of the largest threats facing boreal birds are habitat loss and climate change. Although much the northern boreal has so far been mostly spared from development, the southern portion of the forest has experienced heavy alterations from logging, mining, hydroelectric development, and oil and gas extraction.

What trees are resistant to fire?

Why do jack pines need fire?

New jack pine seedlings grow well after a hot fire. Fire causes the cone of an older jack pine tree to open up and release seeds. Cones that need heat, such as the heat from fire, in order to open are called serotinous cones.

How do pine trees burn?

During the blaze, pine cone spines act as a fire-resistant shell to protect seeds. The heat dries out the shell, causing the spines to open easily after a burn, allowing for better dispersal. Serotinous cone species, such as the Jack Pine, will only release their seeds after a fire, rather than at maturation.Apr 5, 2016

Are boreal forests becoming a carbon source?

  • Boreal forests have acted as carbon sinks - they remove carbon dioxide from the atmosphere and store it in biological materials - for millennia. But our recent study of the 2014 fires in the Northwest Territories shows that some parts of the boreal forest are becoming sources of atmospheric carbon, potentially contributing to the greenhouse effect.
