Reportedly, the Monteray Cypress is one of the species with the dubious
distinction of being listed simultaneously as 'endangered' and as an
'exotic invader' (in Califunny, where Iris douglasiana and I.
missouriensis are also reportedly listed as 'exotic invaders' despite
being native species)

This seems to be true of many of the imported 'invasive weeds' as well -
man messes up the local ecosystem and then blames the opportunistic
species that fill the newly vacant niches...
As a Master Gardener I see quite a few pest problems that are human in
origin - from the people that bring in unidentifiable pesticides and ask
"what can I spray this on?", "I want to spray something, tell me what I
can spray with it" to the people who want something to poison "the
starlings that are driving out the songbirds and tearing up my lawn *and*
something to kill the craneflies now that those 'commies' have banned
Diazinon" and get mad if they are told that (a) that indiscriminate
insecticide use can result in the poisoning of songbirds, pets,
children... and (b) the starlings "tearing up the lawn" are eliminating
many of the cranefly larva and thus actually of some benefit 8-( Of
course there are quite a few other people who are happy to learn that a
more selective, least toxic, Integrated Pest Management approach can give
better results with less adverse impact on desirable species and often
costs less 8-)
