Ancient forests are a designation in the UK - https://www.woodlandtrust.org.uk/trees-woods-and-wildlife/habitats/ancient-woodland/
The Woodland Trust have staff that mind them. I’m not sure what this guys job title was but probably a conservation officer or similar? He was helping us with something about the oldest trees in the UK.
Also, not a he.
I think Moa are a cool candidate for de-extinction, cause we have close relatives, they wouldn’t be too dangerous, and we could house them well in zoos. Plus I’d super like to see one.
