Native planting projects across the site, with a focus on the riparian plantings of waterways, has been continuing over many years with the projects becoming more ambitious as proven success motivates the Trust to continue in these endeavours.

Quarry rehabilitation has involved some of the older quarry pits that have filled with groundwater, while other pits now have spring-fed streams directed through them. The overall aim has been to connect and strengthen different areas of this environment, ensuring the rehabilitated quarry land fulfils a meaningful purpose.

An ongoing exercise in eco-restoration to improve biodiversity is exemplified alongside the Ōtūkaikino Stream (South Branch / Waimakariri River). Walking tracks are available to the public on the land adjacent to Ōtūkaikino Stream, so that the public can enjoy access to the river and observe the native planting programme.
