14. Vegetation

Primary tabs

Vegetation provides habitat to wildlife and ecosystem services such as food and fuel and many other products to humans. Vegetation defines landscapes in people's minds, and is an essential component of any biome or environment.  NWT has large sections of two of the earth's biomes: the taiga and the tundra.

Indicators on vegetation and factors that affect vegetation, such as fire and insect disturbances, can help track changes in the health and integrity of taiga and turndra ecosystems.  Indicators on vegetation responses to stresses like pollution, some land uses and disturbances can provide early warning of changes in northern ecosystems that are harder to measure.  These vegation indicators give information on condition, changes and trends in vegetation communities, including taiga and tundra ecosystems.

Additional indicators on changes in vegetation communities on the tundra are being developed.
