IB Biology SL D4.3.3 Boreal forest tipping point
Practise explaining how rising temperatures threaten boreal forests through drought stress, fires, pests, disease and shifting plant competition.
How this is tested
- explain how higher temperatures increase water stress and fire risk in boreal forests
- link warmer conditions to new pests, diseases and changing competition between trees
- describe likely ecosystem consequences rather than only naming climate change
