A report from the University of Canterbury has revealed that 24 percent of New Zealand’s native vegetation cover (approximately 2.8 million hectares) is estimated to be on sheep and beef farms. This is the largest amount of native vegetation present outside of public conservation land.
The report also estimates that 1.4 million hectares of New Zealand’s native forest is on sheep and beef farms and is likely playing a vital, but often unheralded role in supporting biodiversity and carbon sequestration.
Beef + Lamb New Zealand (B+LNZ Ltd) chief executive Sam McIvor says, “This is a great acknowledgement for our farmers and the work they’re doing as stewards of the land. I hear sheep and beef farmers talking every day about what they’re doing on farm to support biodiversity and it’s great we now have evidence to back up their passionate voices.”
The report, commissioned by B+LNZ, was undertaken by Professor David Norton from the University of Canterbury’s School of Forestry. Supported by Auckland University of Technology staff, the report used satellite imagery to assess the amount of native vegetation, focusing on native forest, occurring on sheep and beef farms in New Zealand.
“The 2.8 million hectares of native vegetation on sheep and beef farms are critical for biodiversity conservation on farms and for landscape-level biodiversity outcomes,” says Professor Norton.
“This finding is particularly important in places where there is little native cover remaining, like those in lower altitudes, on more gentle slopes, and in drier regions.”
McIvor says, “The environment is a cornerstone for our sector and underpins everything that we do at Beef + Lamb New Zealand. This report helps highlight not only the role sheep and beef farms currently play in contributing to New Zealand’s biodiversity, but will also help us identify opportunities to build on this as a sector”.
The desktop report is also relevant to the proposed zero carbon legislation. While further research is needed, the 1.4 million hectares of native forest will be sequestering carbon and most of this is unlikely to be counted in the current Emissions Trading Scheme. Further research is now being undertaken to measure the potential of this native forest to sequester carbon, and this work will help inform B+LNZ’s and farmers’ input into the Zero Carbon Bill.
Along with surveying the extent of native vegetation, the report highlights that New Zealand’s sheep and beef sector is potentially unique globally in terms of the amount of native forest on its land.
The release of this report is one of the first steps for B+LNZ in implementing its environment strategy, which aims for clean freshwater around farms, for the sector to be carbon neutral by 2050, for sheep and beef farms to provide habitats that support thriving biodiversity, and to support healthy productive soils.
