What are the similarities between hot deserts and polar ecosystems?
Low rainfall and little vegetation
Where are tropical rainforests found?

Name and locate a small scale UK ecosystem you have studied.
Epping Forest, Essex, UK.
How is Epping Forest managed?
- Car parks, visitor centre, waste bins, designated paths, information leaflets advising people on how to treat the forest. Ensuring the forest will be left the same way for future generations to enjoy.
- Vegetation at the side of the roads has been cut back so that deer are aware of traffic as there are many deaths from road traffic accidents. Ensures that the deer population will be preserved.
- Pollarding – trees are cut shorter to ensure that they regrow. Ensures there will be timber for future generations.
- The Epping forest conservation volunteers manage the forest by clearing and maintaining footpaths. Ensures vegetation is not trampled and killed
