- Ecological Impacts
- Spruce Beetle
- More beetles can survive in higher temperatures and mature faster
- Trees that lived in balance with beetles, don't have enough natural defences
- Tree lines
- Vegetation Zones shift northwards
- Destabilies existing food webs
- Longer, warmer seasons will benefit Arctic agriculuture
- Soil will be a limiting factor
- Vegetation Zones shift northwards
- Boreal Forest Fires
- Increase in number of extent of Northern coniferous fires
- Boreal ecosystems account for 37% of the worlds carbon pool on land and are efective
- Tundra Ecosystems
- Increase in forest vegatation
- Replaces Arctic vegetation effecting local ecosystems
- Increase in fires due to Global Warming
- Impact on habitats
- Increase in forest vegatation
- Arctic Food Chain
- Species will shift north with forest
- Changes in river pattern will have effect on freshwater fish
- Spread of new species
- Polar Bears
- Will decline/ become extinct
- Hunting season will decrease
- Spruce Beetle
- Places
- Environment
- People
- Sub Regions
