There are many on uncleared land south of Vancouver; it is weedy down here also, with reseeding being frequent.
Thanks for confirming for me. Lots of little ones growing near the big one. We had three of these trees planted in a cluster in my yard when I was growing up that became quite large. Eventually when I was probably a teenager in the late 80s or early 90s, I think one died and two were half dead and were cut down. When I saw so many little ones growing in the back yard of a house that my customer had just purchased, I thought it might be swell to get one and plant it in my yard again to bring back the memory of the three we had before. But now that I know it's not a native tree, I've lost interest. Thanks again, much appreciated.
The main freeway between Blaine and Vancouver passes by thousands of non-native birches at certain points, as I recall numbers of these can be seen to be Betula pendula; there is probably also some involvement of B. pubescens, as well as perhaps B. occidentalis (B. fontinalis)*, with hybrids being present as well. *This one is actually native, along with of course the B. papyrifera that are conspicuous in parts of NW WA and SW BC.
