Re: Mexico Spotted Owl--Open Questions (fwd)



G'day Jim (and everyone else who's listening in because I've included you),

your questions were forwarded to us in forest@funet.nic.fi, and I thought
I'd like to have a bash at one or two, and also ask if you'd be kind enough
to post the address for subscribing to CONSLINK, as I'm interested in it
and maybe some others would be as well.  I've taken the liberty of
extracting the bits of your message that I'd like to refer to.

I think the key question is: which way it will go.  It seesm to me that
this issue is of concern to those who are concerned about how the
legislation *could* be used if someone had the agenda.  It's kind of like a
double edged sword: if it's strong enough to reliably protect something as
hard to pin down as an 'endangered species', there will probably be
fallout: what aren't you allowed to do in your backyard if an owl
occasionally sits in your tree?  Now you might not mind about that (and I
wouldn't either) but many voters do, and will continue to do so whilst the
dominant culture here (I regretfully quote an anonymous (fortunately)
student's comment: "Never forget that the rights of the individual are more
important than the rights of society.") remains the dominant culture here.

Want to disagree with it?  By all means do - thank heavens we have that
option!  But watch which way they vote.  Want to change their minds?  By
all means try - thank heavens we have the chance!  But watch which way they
vote.  When it all comes down, I suspect that the voting public will not
empower the legislators to protect species given the perceived costs in
personal freedom.  And then what?

I have never heard of small trees suppressing large trees. That sounds like
rubbish to me. Does anyone have any evidence of that happening?  Insects,
disease, and fire suppression make much more sense as being bad things.

Of course!  But was it on an equal area basis?  Or on a tree for tree
basis?  And what does 'tend' mean?  If owls roost in trees, then they'll
roost where trees are.  But where do they hunt?  I wouldn't mind
(intuitively) betting that the owls would stick near to the edges, because
it's easier to catch dinner in the open.  To my mind, the key question is
not which system they prefer (I really couldn't care less; logging happens
while we want forest products) but whether they can cope with proximity to
logging sites.  Does anyone have a pointer to that study?

>Do these forests need to be managed?

I think (and I assert it without proof) that any forest which experiences
human impacts needs to be managed - if only to ameliorate the effects.
Mother Nature gets on fine without us, sure, but there isn't much space
left that we don't touch in some way.  Do you believe that even a camping
site wouldn't create havoc if there weren't someone around to enforce
decent behaviour?  I don't.

Right!  Excellent question.  I'll bet nobody knows.  This is a fantastic
example of the type of question forest managers have to cope with annually.
Aren't we lucky they're trained!

An excellent set of questions without ready answers.  A small point: there
really is no such thing as a controlled burn.  The label of currency is
'prescribed burn'.  As to who is the best entity to manage the forest - may
I broaden the scope a little?  What do you mean by 'best'?

best regards ;-),
