Pest control may be last chance for Waikaia mōhua

Pest control may be last chance for Waikaia mōhua


The recent rediscovery of threatened mōhua/yellowhead in Waikaia Forest, northern Southland, means a pest control operation planned by the Department of Conservation (DOC) soon is essential.

DOC Catlins services ranger Cheryl Pullar said consent by Environment Southland for the drop had been granted and they expected it to go ahead in August or September.

Ms Pullar said the sighting of mōhua last year surprised DOC staff as they thought the birds had disappeared from this area during the last beech mast in 2000. This year’s beech mast means rats, mice and stoats could reach damaging levels again by summer.

DOC scientist Graeme Elliott said if pest control was not carried out in Waikaia forest, mōhua would completely disappear from the area forever. “This may be the last opportunity to protect them and recover this population,” Mr Elliott said.

Mōhua were once common in Southland but now lived only in fragmented populations.
“They’ve already gone from patches of bush around Southland and this year’s beech mast will finish them off in Waikaia if we don’t control the rats, mice and stoats,” Mr Elliott said.

“Pest control will allow this population of mōhua to recover to similar levels of those in the Catlins, where flocks of dozens of mōhua are visible, especially along the upper end of the Catlins River Walk.”


Ms Pullar said DOC was in the planning stages of the aerial drop which would cover just under 7000 hectares of the Waikaia Forest in northern Southland, as part of the national Battle for our Birds operation. Ms Pullar and other staff have been consulting with the local community on the operation.

Silver beech in the area were masting heavily and tracking tunnels by DOC to measure the density of rats showed there was a rise in the population, Ms Pullar said. When the seeds ran out, rats and stoats would target native species, including mōhua.
DOC planned and delivered these operations carefully to ensure aerial sowing of 1080 was accurate.

“Boundaries of the areas will be marked with GPS technology and buffer zones from the boundaries, around waterways and other non target areas have also been plotted. Signage warning of the operation will be put up at entries to the forest, and tracks within the operation areas will be cleared by DOC staff at the time of the operation,” she said.

Up to two weeks before the aerial 1080 operation a pre-feed operation will be carried out using non-toxic baits dropped over the entire block at about 1kg per hectare. The pellets containing 1080 will be distributed about a week later. The 1080 is biodegradable and disperses quickly in water to non-toxic levels. The pellets will contain deer repellent to control by-kill.

Conservation Minister Nick Smith recently confirmed Battle for our Birds operations would be carried out in 29 forests throughout the country this year, covering 700,000 ha by November. Another 14 forests covering 200,000 ha were on “close watch”.
