At risk of being repetitive, this is where I can't support the
native/non-native dichotomy. As I believe I've said before on this list, I
live on a hillside forested with 80-120 year-old "native" Douglas fir trees,
but amid these are a few huge, open-form oaks and madrones, 200-400 years
old. The oaks are remnants of a human-maintained oak savannah, maintained by
Indian burning for probably 5-10,000 years. When whites exterminated the
Indians and suppressed fires, the firs crowded out the oaks. So which is the
native ecosystem? Which do I try to recreate? Or do I go back to the
pre-human vegetation of 10,000 years ago, which was a post-glacial
birch/aspen forest, neither species being "native" any more?
In Australia, the bush is a human-made artifact created when humans moved in
40-80,000 years ago and began setting fires, eliminating the previous tree
cover. It's a terribly unstable landscape when not burned regularly, hence
the current species loss.
"Natives" only exist when we take a human-centered, 5-50 year viewpoint,
trying to preserve what was present when we arrived. I'm not saying we
should plant whatever we please, but the idea of some archetypal "native"
flora is a product of our minds, and not of nature. Native plants are
simply the species that happen to have arrived in a locale, found it
suitable, and crowded out the earlier inhabitants. If another adaptable and
appropriate species is brought by a human rather than by a bird or
tectonics, why should it be rejected? The more I look at restoration work,
the more arbitrary its choices appear--which is not a defect, just something
we should pay attention to. Most of this planet has been manipulated by
humans, and that needs to be kept in mind when we dream of "restoring" a
former flora.
