Alpine adventurers help rock wren bounce back

Rock wren in the Homer Saddle and Gertrude Valley are making a comeback thanks to a trapping project run by the Southland Section of the New Zealand Alpine Club (SSNZAC).

In 2012, the rock wren population in the area were in catastrophic decline. A team of DOC researchers found that all of the nests were being attacked by predators. To protect these vulnerable birds from local extinction, SSNZAC set up a predator trapping programme.

The number of rock wren in the Homer-Gertrude area is now steadily increasing. DOC has been monitoring the population and since 2013 the number of breeding pairs has increased from 10 to 33.

SSNZAC Committee member Stanley Mulvany said the club was thrilled by the impact of the predator control:

“We are really excited by the success of the rock wren population in our monitored areas. This programme seems to have made a significant difference to the survival of this, New Zealand's only true alpine bird.”

“Our trapping programme is a team effort by SSNZAC, the Fiordland Tramping and Outdoor Recreation Club, the Hokonui Tramping Club and the Southland Tramping Club, assisted by the Department of Conservation”

DOC Fiordland Operations Manager, Greg Lind, said rock wren monitoring results show the fantastic outcomes that can be achieved by community groups taking action for conservation.

“The work SSNZAC are doing is making a real and positive difference to the survival of rock wren in Fiordland. This project is a great example of how volunteer work being done by the community can produce amazing results.”

DOC will continue to monitor the rock wren population in the Homer-Gertrude area through the next breeding season.
