[Scpg] [Lapg] Interesting perspective about invasive species

i highly recommend the book!
it's not fair to start the discussion until you can
see the long term facts, science, and data.
FYI.............
david thedoropolus is the steward of j.l. hudson
public access seed bank. it used to be the largest
until SSE started taking corporate monies form
kelloggs etc.
also,
i was not joking about planting invasive species.
i just planted some variegated arundo donax in
pasadena in the arroyo seco, right near the rose bowl.
today i planted valerian in silverlake
tomorrow i am planting spearmint in a veggie garden
and soon i will plant very large eucalyptus in on open
chaparral fire zone, kinda close to the house.
if you want to knopw the circumstances i would be glad
to share.............
ie the arundo donax went in a very special jungle yard
underneath huge trees and massive vines in a very
shady zone. no worries about it getting out of
control.
i really hope it lives!!!!
it all about context and observation. no such thing
as invasive, no such thing as native vs non-native, no
judgement about nature or presumption that we can even
begin to understand the complexity.
jeez.....we still don't even get the interconnectivity
of a forest.
i VOTE FOR DIVERSITY.
