In central Europe there is, e.g., a debate about the role and future of the Douglas fir, which was also introduced from North America centuries ago:

Their acidifying potential was also significantly lower. An example I could find: https://www.agriculturejournals.cz/pdfs/jfs/2013/09/02.pdf https://www.agriculturejournals.cz/pdfs/jfs/2013/09/02.pdf
