Since climate change will nevertheless put stress on many species and ecosystems every effort should be made to improve the resilience of native species, ecological communities, natural areas and habitats. Far less disruption to nature will occur if the vast majority of native species are actively assisted to survive is-situ in their existing habitats, while major efforts are made to reverse global warming. This is still the most effective strategy even if it were to take hundreds of years to bring the global climate back to something like today's conditions. The survival in-situ strategy will not be appropriate for some species or ecological communities. Such species and ecological communities need to be identified as soon as is technically feasible.
Likely candidates are alpine and coastal species.
If coastal ecological communities are to survive a rise in sea level new habitats must be allowed to develop or be created to replace those that are lost. Special arrangements will be needed on the coast to provide private land for the purpose. Alpine environments should be managed to reduce stress and encroachment. Other species and ecological communities may need new habitat to be created. Some species may need to be protected out of the wild if enough suitable habitat cannot be made available.
