Retiring Farmland into Ngahere

What are we doing?E aha ana mātou?

When less productive farmland is ‘retired’ into ngahere (bush or forest) there can be positive impacts on water quality, greenhouse gas emissions, farm management and profitability.

This project builds on 10 years of results from a Primary Growth Partnership that retired over 400ha of marginal land into manuka plantations for honey, then applied that knowledge to broader land retirement into mixed natives on steep erosion-prone slopes, riparian margins, and critical source areas. This work identified potential savings of more than 50% of the current cost to establish native plantations, by replicating the natural reversion process.

This project will create short videos and graphics sharing best-practice methods for low-cost, broad-scale land retirement into ngahere, covering important factors including: weed and pest control before planting, mix of forestry-grade coloniser species, planting density for various tree species, soil biome, and establishment timelines.
