Mr Penrose said in the last two years stoats and ferrets had become ``prevalent'' around Lake Hayes.
The pests had a voracious appetite and targeted tuis, bellbirds, fantails and grebes on a daily basis.
The trust hoped to eradicate the predatory mammals ``and hopefully bring back a bit of quiet enjoyment for people in the area'', Mr Penrose said.
It was expected about 10 traps, provided by the trust, would be set up off the Lake Hayes track in "discreet locations'' to ensure they did not affect the public.
Volunteers were required to monitor the traps, remove pests from them and re-set them again, he said.
Anyone interested in volunteering could attend a trapping information evening at the Lake Hayes Pavilion, which begins at 7.30pm tomorrow.
