The largest and
most endangered lizard in NZ; the chevron skink is alive and well in
Glenfern Sanctuary.
Ben Barr, currently
doing fieldwork towards a Master’s Degree on the impact of rats on
chevron skinks, has caught 50 chevrons in two mature valley
catchments in Glenfern Sanctuary. These range in size from neo-natal
at 100mm to full size adults at 350mm. Miniature transmitters have
been attached to three adults to monitor their dynamics in varying
environments and weather conditions.
Only 300 chevrons
have been found in the wild since they were first discovered on
Little Barrier and Great Barrier islands so to have 50 turn up in
two valleys on Glenfern Sanctuary is remarkable.
Rat and cat control
in Glenfern Sanctuary over the last seven years may have had an
impact on the ability of these skinks to survive. The pest exclusion
fence now under construction across the peninsula can only enhance
their survival rate.
“I feel privileged to
have this iconic endangered species living so close on our property
and to be able to provide a safe environment for their continued
survival,” says Tony Bouzaid, Chairman of the Glenfern Sanctuary
Charitable Trust.
Glenfern’s
Robins (Summer 2006, Issue 5) (abridged)
Tony Bouzaid
reports on the progress of his robin rehabilitation programme in
the Glenfern Sanctuary area of Port FitzRoy.
At the end of
January we thought we had come to the end of our robin-breeding
season. When Rebecca left us on the 9th she had banded 19 chicks and
we still had one in the nest at B45, the only one of 3 eggs that
hatched....
On the
15th Suzie found that our black petrel pair had returned and laid
an egg in their burrow under the puriri tree. We checked the
band to ensure the bird on the nest was one of the original
parents and we set up sticks at the entrance to the burrow to
wait for the parents to swap incubation...
After Judy
Gilbert told me she had two pairs of robins still nesting I
decided to check on mine...This brings our total of fledged
robins to 21.
On March
17th driving up the Okiwi hill towards Claris, Mal sighted an
unbanded robin on the side of the road. This is good news as it
means that at least one pair of the robins that did not stay in
the protection of the Kotuku Peninsula managed to fledge a
juvenile. There may be more out there so keep your ears and eyes
open.
With
another possible robin sighting near the top of Hirakimata (Mt
Hobson) we may be seeing a resurgence of the breed on the
Barrier!
