Hi Folks,
For the interest of anyone who frequents Jerra Wetlands:
I had a call from a Canberra Nature Park ranger during the week re further
willow control works planned for Jerrabomberra Wetlands during March.
The target area covers both sides of Jerrabomberra Creek from the northern end
of the Silt Trap pond to the large pedestrian bridge over the walking path.
Works will include frill poisoning of 'crack' willow only - these trees will be
left standing as dead wood.
On the western bank only, some of the existing dead wood will be removed -
this is mitigate against damage to structures during major flood events.
'Weeping' willows (which is apparently most of the trees) will remain untouched.
During April an area within the treated zone, on the eastern side of
Jerrabomberra Creek, will be planted with native vegetation.
If any COG members know of a specific roosting tree and have reason for it to
be retained (if it is 'crack' willow) please let me know before the end of
February so it can be marked to stay.
Also, following on from a bit of discussion at the last COG meeting, I
commented to the ranger about the large numbers of rabbits at Jerra.
She said they had put down poison baits, but that this had had limited success
because an antidote to the poison (vitamin K) was present at high levels in
green grass - and that there had been heaps of that around this year.
They will be doing more rabbit control in future, but at a better time of year
and in a more systematic way (ie including the sewage works, where she thought
most of the rabbits were coming from, and the education establishment).
Cheers
