At more than 21,000 ha, this forest tract is the second largest but most intact forested habitat in the Eastern Northland Ecological Region. DOC administers 16,210.7 ha, with 250.2 ha under Conservation Covenant and 427.6 ha under covenant with the Queen Elizabeth II National Trust.
With over 360 indigenous species of plants, this forest is one of the most diverse in New Zealand. It supports nine threatened fauna species and several others which are endemic, or regionally significant.
The mature kauri forest remnants are especially important in that less than 1% of the original cover of this forest type is left (Northland CMS). The lowland mixed kauri forest is one of the best remaining examples of this type.
