The other problem is that non-native pests and diseases keep killing off trees. For example, the article mentions mountain ash as a species that's endangered. They're suffering from a nasty fungus that came here from Asia - the Asian species of ash have evolved to defend themselves from it, but the European ones have no defences and can't survive infection.
Even those sad cases of cutting down old growth forest won't be replaced by agriculture or industry - new trees will be planted. Hopefully they'll allow native trees to-grow instead of planting imported trees. I couldn't find details if they're doing clear cut or selective and giving time for remaining trees to multiple.
it's been reported plenty of times that europe keeps getting more forests e.g.[0]
> Between 1990 and 2015, the area covered by forests and woodlands increased by 90,000 square kilometres - an area roughly the size of Portugal.
The problem with european forests is mostly, AFAIU, the fact that the few remaining old growth ones are still being cut, such as in Poland.
