[obol] invasive species

[Linda Fink]

Hooray, Mike! I couldn't agree more. What are we going to do as the 
climate gradually changes? Eliminate all the survivors because they're 
non-native? Ecosystems are not stagnant... Linda Fink, who loves her 
ivy-covered wall even though she has to climb a ladder several times a 
year to whack off all the developing flowers (and liberate the nest 
boots that the chickadees love)

Yes, I know that Russian Olive is non-native and considered a weed 
species, but the facts are this introduced tree has been here on the dry 
side for over 100 years and many native bird species now depend on this 
dense berry producer for winter survival ( WOSNews 103). O well the 
damage has been done for the most part and now we need to keep tabs on 
bird species that have depended on invasive species for many 
generations. Just my opinion.
Later Mike
