Arctic terrestrial ecosystems are under increasing pressures from:

  • Climate change
  • Habitat fragmentation
  • Regional development such as oil, gas and mineral exploration and production, hydroelectric projects,
  • Contaminants, 
  • Urbanization,
  • Increased agriculture, 
  • Air traffic, 
  • Invasive species
  • Competition from the movement of more southerly species

The composition of Arctic biodiversity is highly related to temperature. Temperature can affect terrestrial ecosystems through thawing permafrost, snowmelt, drought, fires, changes in phenology (with subsequent implications on the food web), encroachment of invasive species, pest outbreaks and disease transmissions. For some species that feed and reproduce in the short Arctic summer, longer growing seasons may be an advantage, but specialized Arctic wildlife are predicted to be negatively affected.

Exactly how these pressures - alone and in combination - affect terrestrial species and ecosystems is unknown because the Arctic's complexity and size make it difficult to detect and attribute changes. In addition, existing terrestrial monitoring efforts are often uncoordinated, limiting the ability to efficiently make effective management decisions, despite increasing urgency and pressure to act.

The Circumpolar Biodiversity Monitoring Program (CBMP) is working with partners, including existing terrestrial monitoring networks, across the Arctic to harmonize and enhance long-term terrestrial monitoring efforts. These efforts are led by a Terrestrial Steering Group.

The Arctic Terrestrial Biodiversity Monitoring Plan will guide monitoring efforts in the Arctic terrestrial zone and was released in October 2013.
