In 2011, the Abel Tasman Birdsong Trust began what would end up being a nearly $1 million project to control pines of cone-bearing age from high priority coastal areas of the park. The arrival of Project Janszoon meant the completion of this initial project was accelerated, and the initial strike was completed in 2015.
Since then, hundreds of thousands of wilding pines have been poisoned, stretching from Tinline Bay in the south to Taupo Point in the north. Follow-up control has been undertaken by Project Janszoon and DOC, with the Birdsong Trust completing the initial control of some small remaining areas, with support from the Abel Tasman Foreshore Scenic Reserve Fund.
