Sorry, shouldn't do this while doing other things (cooking for imminent
guests). My failure to comment on the Gang-gangs and the timing there
was inadvertant. I know nothing about the process that led to the
lopping occurring while the chicks were still in the nest, which
certainly seems most unfortunate. My comments were more on the general
situation.
back to the kitchen....

For what it's worth, one of the leading independent experts advising on
the process is someone I know very well indeed, and have worked with
for a couple of decades. He is not only an unchallenged expert on tree
health, but has done more for conservation at a practical 'on ground'
level than most of us could ever claim to have done, including fighting
to save numerous remnant woodland trees in Canberra and beyond. It was
he who alerted the Commissioner and TAMS to the presence of the
hobbies' nest and the need for a delay.
Nonetheless the entire inside of the tree was rotted out - which of
course makes for great nesting hollows!
While any tree loss is regrettable, let's keep this one in perspective.
It is a planted tree, not native to the immediate area (locally it is
indigenous to the streamlines and sheltered gullies of the Brindabellas
and Tidbinbillas). With respect we might be doing more for conservation
if we were to focus more on the many pre-European trees under threat in
suburbia both current and planned.
I trust this doesn't lose me any friends, or cause anyone to mistake me
for someone who doesn't care passionately (and actively) about trees,
birds and biodiversity in general.
Have a relaxing and birdsome end of 2009 and entry to 2010 all!
cheers

I emailed TAMS this morning to
express concern about the tree pruning. I asked whether expert advice
had been sought in relation to the nesting birds and also what
qualifications the various "experts" had.
Here's the response I received for
what it's worth.

I too
share your disappointment about the extensive
pruning of the tree in Corroboree Park. Four independent condition assessments on
the tree however, classified
it as hazardous. Given its
condition, height and location it
was necessary to remove the hazardous sections. Provision was made for the Gang,
Gang nest. On close inspection from the travel tower no
nest could be located for the Australian Hobby.
Attached is information that about
the tree condition assessment and removal process that was provided to
residents adjacent to the Park.
