Then came more sedimentary layers and more diabase intrusions. The park is part of the northern boreal forest, but it lies at the northern and eastern limits of many southern and western plants. The result is an exceptional mix of plant life. Cloudberry, arctic bistort and butterwort grow hundreds of kilometres south of their usual arctic habitat. Some 24 types of orchid grow here, including arethusa, calypso, and the plentiful pink lady's slipper.
Ferns also abound.
The park is home to a wide range of wildlife including white-tailed deer, red fox and porcupine, moose, bears, wolf and lynx. More than 190 species of birds have been recorded at Sleeping Giant.
