DOC's work with kauri snail
Past conservation efforts
Management of priority kauri snail colonies has been carried out since the early 1980s. Most of this management has consisted of poisoning rodents, enhancement planting, fencing colonies, and stock control. These actions have successfully allowed some species of kauri snails to recover from near extinction to colonies of some hundreds.
Translocations of kauri snails have led to the establishment of populations at Awhita Peninsula, Kaimai Ranges, Waitakere Ranges, and Warkworth. Captive breeding has so far resulted in limited success.
Research has also been conducted on different aspects of snail ecology.

Recovery Plan in action
The first Department of Conservation Giant Land Snail Recovery Plan was approved in 1995 and is currently being updated. The new plan sets in place a series of steps that will promote the recovery of the snails. It also outlines different management options, and a work plan.
The long-term goal of this recovery plan is:
- 'To preserve and enhance populations of all Placostylus and Paryphanta species, and Rhytidarex buddlei in their natural range. The emphasis is to direct management towards the most genetically and morphologically distinct and viable populations.'
Goals for the term of the plan:
- To encourage and support public and community protection of northern giant land snails and their habitat throughout the term of this plan.
- To secure representative populations of distinct taxa.
- To conduct research required for effective management.
