Control methods include trapping, and bait stations containing Feratox (encapsulated cyanide).
Detection devices such as chew cards may be used for indicating possum presence prior to implementing control and also after control to demonstrate the effectiveness of control measures.
Leg hold and kill traps will be set in areas where it is not possible to use toxins or where field operatives believe an alternative method is required, for example when targeting feral cats, ferrets and stoats. In some instances, it may be necessary to use cage traps for live capture.
Traps will be raised set where ground birds are present. No flagging tape is to be placed near traps in Kea areas and traps should be set under cover of trees so as not to be visible from above.
Field operatives use a hand-held PC, known as a PDA, as well as hand-held GPS to collect data during deployment, checking and removal of control devices and to verify sign checks.
