Should you save Treedwell's tree?
The mayor of Treedwell is keen to cut down an old tree to make room for more housing. Do you think the tree should be chopped down, or do you sympathise with the protestors?
In order to decide, you'll need to think about how important the tree is. If it is chopped down, will it just be the tree that is affected?
How can you investigate the importance of trees?

Trees are important habitats for a variety of animals. What can you see living on your tree? Are there any birds' nests? Can you see any invertebrates in our guide?
Look at the ground around the tree. Do you see any burrows or holes? What animals do you think could be living in those holes? Try searching on the internet to find out.
