Ecosystem services are the benefits people obtain from ecosystems: provisioning services (also known as goods) such as food and water; regulating services such as flood, pest, and disease control; cultural services such as spiritual and recreational benefits; and supporting services, such as nutrient cycling, that …

What services does the Arctic provide?

Reindeer herding; commercial fisheries; commercial and subsistence hunting, gathering, and small-scale fishing; and recreational and sport hunting and fishing are the provisioning services addressed here. These are the main sources of food produced in the Arctic.

What are 3 ecosystems services?

How is tundra ecosystem changing?

Global warming has already produced detectable changes in Arctic and alpine tundra ecosystems. These ecosystems are being invaded by tree species migrating northward from the forest belt, and coastal areas are being affected by rising sea levels. Both phenomena are reducing the geographic extent of the Arctic tundra.
