Northland landowners wanting to know more about how to set-up a Community Pest Control Area will get the chance to find out how at an open day on Sunday.
The area's naturally mild climate makes it a good habitat for animals and plant pests, and the first control area, or CPCA, was set up by Northland's regional council several years ago in a bid to limit the population growth.
Council pest control officer Mike Knight says because the scheme is run by the landowners they know which areas need protection and what pests they want to control.
Mr Knight says initially the council meets the full cost of pest management, then gradually hands back financial responsibility to the landowner as levels come under control.
He says more than 20 schemes are operating in the area.
The open day is being held at the Okaihau farm of Alister and Lynn Candy on Sunday.
