But Paris would welcome me with open arms! (Hint to Cute Husband)
Apparently, the Cherry Tree (we are pretty sure it is a Black Cherry) which we recently discovered in the LoveNest habitat would be unwelcome not only in Paris, but in most of Europe as well.
According to this article from Science Daily, the North American Black Cherry is super invasive in Europe.
We can thank a soil-borne pathogen that exists in the U.S. for keeping our Black Cherries in check. In Europe, the pathogen (Pythium) is just too wimpy to regulate these trees from taking over plots of land and pushing out European native trees.
But, this, I think, is the most important bit of the article...
"Evidence of an invader encountering more aggressive enemies in its native versus non-native range provides new evidence for the popular hypothesis that invasive species-whether plants, insects, or other animals-thrive outside of their native lands in part because they have escaped their enemies."
