For those who are alarmed at the message posted by
Kathy Cook on 16 July concerning the destruction of ibis and cormorant
nesting trees please find below a response from the ACT Government.
Hi
Chris,
The
reason the trees are being removed is due to water quality issues in that
particular dam on Yowani GC.
The
Environmental Protection Authority (EPA) (ACT Government) has found that at
certain times of the year, the water entering Sullivans Creek from this dam does
not meet environmental water quality standards due to blue-green algae blooms.
The blooms are related to the high nutrient level in the dam, which is mostly
from Ibis droppings during breeding season and to a lesser extent from
fertiliser. The EPA has told Yowani that they must do something about the excess
nutrient levels in that particular dam and the algal blooms. The main way
to reduce the high nutrient levels is to have no or few Ibis using the island.
Hence permission was given to remove Ibis habitat from the island, outside
of breeding season.
Hope
this helps to answer your question.

Destruction of Ibis and Cormorant nesting sites at Yowani Golf
Course
Very distressing to
hear today that Yowani Golf Club has destroyed about half the nesting trees on
an island between the 16th and 17th fairways, used by mainly Australian White
Ibis as well as Little Pied and Little Black Cormorants. More than 200
nests have been counted on the island in recent years. COG members will be
aware that this is one of the very few nesting sites for white ibis in the
ACT. Who knows where the birds will go when they return to start nesting
in the next couple of months. It is understood that the remaining trees
will be chain-sawed in the next few days. I am unaware what planning
permission was given for this, but even if it has been agreed by the relevant
authorities it seems a sad indictment on our society’s values.
