I'm writing a fantasy with trees which are extremely wide, and fairly tall. Their width would be about 40-50 metres.
So I was wondering if the climate needed to be similar to that of a rainforest, or something that's instead colder, for these trees to fit the environment they're in.
However, you have to take into account that there are people living in treehouses that are situated on these trees, so human factors come into play too (eg farming etc).
If anyone has an idea on what climate would be most suitable for this type of scenario, that would be greatly appreciated!
