| | Boreal Forest - Ecoregions - Sierra Club |
 | | Although, the boreal forest conjures up images of vast pristine wilderness, an unending expanse of conifers in an area that has been left untouched by human interference and industrial development, it is increasingly threatened by a range of resource extraction and other activities. |
 | | In North America, the boreal ecoregion extends from Alaska to Newfoundland, bordering the tundra to the north and touching the Great Lakes to the south. |
 | | Also characteristic of the boreal are innumerable water bodies: bogs, fens, marshes, shallow lakes, rivers and wetlands, mixed in among the forest and holding a vast amount of water. |
