Re: Native Plant Rescue

That's interesting. Several years ago, I attended a conference that 
attempted to assess the impact of Eucalyptus on California birds, 
insects, native plants, etc. Much of the field work was done in a 
season or two by students. The preliminary results showed that there 
were differences, but of degree rather than orders of magnitude.

The other day I was talking with a friend who mentioned that the 
"wrong" trees (certain ones that aren't locally native) in a 
neighborhood can draw larger numbers of predators (raptors and 
corvids) and diminish the songbird populations. But all neighborhoods 
around here have a mix of trees and shrubs, mostly nonnative.
