Emissions Trading Scheme guide

A guide to erosion control/spaced plantings being eligible to enter the Emissions Trading Scheme (ETS) is now available on our website.

For erosion control/spaced plantings to be eligible to enter the Emissions Trading Scheme (ETS), they must meet the ‘forest land’ definition’ as well as be ‘Post 1989’ land. Forest land must be at least a hectare in size and have (or will have) tree crown cover:
- from forest species of more than 30% in each hectare
- with an average width of at least 30 metres.

Field day Pakaraka Station report

Check out the report on the Field Day at Pakaraka Station. A great example of the use of trees to mitigate the effects of devastating erosion.

Let's stop erosion!

Retaining fertile soil on the land is in the interests of all New Zealand. Without tree protection hills fall apart in severe rain storms. Poplars and willows planted for erosion reduction stabilise our pastoral hill country, increase water storage, reduce sediment transfer, improve water quality, benefit stock and enhance the farm environment.

There are poplars and willows to suit each region and location.

Working in close association with regional authorities and industry partners, NZPWRT develops adaptable planting materials (poplar & willow), provides technical support and promotional information to assist landowners to reduce soil erosion, lower sediment transfer off farm, and improve water quality.
