Forest Vegetation - Nahanni

Forest ecosystems are a vital component of Nahanni National Park Reserve, covering approximately 80% of the park. Forest vegetation condition is currently a composite of three sub-measures: changes in (1) mature spruce stand growth rates, (2) mature spruce stand mortality rates, and (3) understory vascular species composition. The measure focuses on river valley white and black spruce-dominated stands. Data collection is conducted at permanent plots by field technicians once every ten years.
