Both bat/pekapeka species are threatened by rats, cats, stoats and possums. Because bats have such large home ranges, with a single colony occupying up to 100km2, pest control to protect them needs to cover large areas.
Our research in the Eglinton Valley in Fiordland has shown the long-tailed bat population only started recovering when pest control was expanded to more than 3000 ha. DOC’s Tiakina ngā Manu programme is essential to recover bat populations in our forests.
Bats are monitored at several places throughout New Zealand to inform and refine how pest management can protect bats.
The DOC Electronics team developed the “AR4” bat recorder, now widely used in NZ to survey for bats. DOC also administers a national database of bat records so we can learn more about bat distribution and how that changes over time.
The NZ Bat Recovery Group has developed best practice guidance and advice notes for bat workers.

Information and resources for the AR4 bat recorders are available from the DOC Electronics web page. An app for testing recorders is available from Google Play Store (Look for “DOC – Bat Recorder Tester” from Tussock Innovation Ltd).
