Many trees on the list already grow naturally here but some come from warmer or drier regions like the Corsican pine from the Mediterranean or the coast redwood from North America.
Their inclusion reflects growing interest in assisted migration, which means introducing tree species now that are suited to the climate the UK is expected to have in the future.
The England Species Reintroductions Taskforce, an independent advisory group, guides conservation and species translocation efforts.
Dr Dalrymple, a member of the taskforce, told the BBC: “We’ve been tracking biodiversity loss for years…do we just watch it happen or act before it’s too late?”
One suggestion would be to plant the the seed of the common oak currently growing in the Georgia and Azerbaijan border in the UK. It grows in similar soil and environmental conditions to southern England and could be used to sustain future oak populations in the UK.
However, assisted migration also poses challenges.
The UK’s increasingly extreme weather, like late spring frosts followed by heatwaves, brings conditions that “are really difficult for trees to adapt to”, said Dr Tew of Forestry England.
While some tree species might thrive in the next 50 to 100 years, they may not be suited to weather conditions in the UK now.
