Trees Don't Move (Quickly Enough?)

Conservationists are divided on the merits of 'assisted moving' for trees. Many UK organisms are in the process of relocating to the North, in response to climate change. Trees, however, cannot (for obvious reasons) make a fast leap (https://www.theguardian.com/environment/article/2024/aug/19/the-world-is-getting-hotter-could-helping-englands-trees-migrate-northwards-protect-them-climate-aoe). Some conservations think that help is required to preserve native tree species. They advocate planting saplings in cooler locations. They would also replace their southern bretheren by more heat-resistant species from overseas. Other conservationists object to the introduction of yet more 'alien' species. Alien plant species can be problematic but climate change may give us little choice?
