Our first monitoring after the
second aerial bait drop took place in September 2009 with only one rat
print found under a house in Arthur’s Bay. After a year of major rat
incursions, aggressive perseverance with trapping and baiting, adapting
our techniques and timing to the invaders we are not too far from where
we started.
While we have still caught some rats between the last two monitoring
rounds none have been caught since and very few fresh prints to which we
are responding.
We are finding very few rats in the buffer zones outside the fence which
would indicate that we are not currently being reinvaded. Some of these
dead rats have been removed by cats and we have discovered one cat print
inside the fence.
August 24th to the 26th was the occasion of the Sanctuaries of New
Zealand Conference at Orama and enabled us to meet other dedicated
operators and to catch up with how other Sanctuaries are dealing with
pest incursions. About 60 delegates visited Glenfern and were guided in
five teams through the Sanctuary to the kauri tree and back.
The Conference also enabled our contractors and volunteers to have a
detailed discussion with John Innes of Landcare Research about our
particular problems. From this we learned that the rats we were catching
over the last two months and assumed to be juvenile ship rats were in
fact adult kiore! You might think a rat is a rat but in fact the kiore
are not as destructive as ship rats. Now we know how to tell the
difference.
Interpretive Display Centre
Over the last year we have been building a new office and education
centre for visitors to the Sanctuary. A large monitor enables us to give
a PowerPoint presentation of the history and operation of the Sanctuary,
what we have achieved to date and where we are headed in the future for
the whole of the Kotuku Peninsula. We can seat up to 20 people in the
display room and look forward to showing visitors what can be done.

Rodent Fence
We are fundraising to build a rodent proof fence along the drive just
behind the shoreline to capture the rats that have been coming across
the mud flats and along the intertidal zone around the end of the fence
in Port FitzRoy. Despite two rows of bait stations and traps at 10-20m
intervals on the shoreline and behind, the rats were still crossing into
the Sanctuary. The rodent fence is only 1300mm high and extends 500m
from the end of the existing fence to just before the FitzRoy House
wharf. The total required is just over $100,000 but we have already
raised 25% of the cost. We are very grateful for the help provided by
our volunteers and the assistance we have received from Lotteries, the
Biodiversity Funds, World Wildlife Fund, ARC and the Auckland City
Heritage Fund. We are always on the lookout for more volunteers as so
much is being asked of so few.
