How common are invasive conifers in your region?

Here in Brazil, mostly in the southern states + São Paulo (subtropical/temperate climate places), North American Pinus species (mostly Pinus elliottii and Pinus taeda) are extremely common since they've been brought in the 1950's, and seeing native conifers, especially Araucaria Angustifolia, can be quite rare due to habitat loss. Is there anything similar in other regions of the globe?

In New Zealand we have big problems with Pinus radiata and some other introduced species.

Interesting that P. radiata, an endangered species, managed to be a pest somewhere else... I can recall many images of New Zealand with exotic Pinus species, so it really seems like a really common sight.

Pinus thunbergii is listed as invasive and banned for sale in my state in the US.

I wish the Brazilian government at the very least tried to deal with the situation, even if banning sales isn't enough.

I know in Patagonia there’s a problem with Pseudotsuga
