Urban tree experts don’t expect introduced species to cause major disruptions to native wildlife.
Sigh.
The swarm of Bradford pear trees, wisterias, English ivies, porcelain berry, barberry, and autumn olive trees (and many others) choking my surroundings don’t give me happy feelings about this.
Typically with climate change (like ice ages, etc, not anthropogenic), plants migrate to stay in their ecological niche. With temperature/precipitation being the major factors, plants tend to migrate up in latitude and altitude as climates warm. That’s why you end up with “sky islands” where a mountain might have a species not seen for a large distance further north at lower latitudes. Anthropogenic climate is probably too fast for most trees to migrate, but I think we should do our best to source trees that are along the migration path for a given area. The author’s manzanita is actually a great example.
It is, and it lives in a very different fire regime from what is typical of the pacific northwest. It might be attractive, and fantastically drought-tolerant…but I wouldn’t want a neighborhood planted like chaparral. That’s a plant community that burns. Fast.
