Overall Health 10%

Many native species hold significant meaning and relationships with mana whenua of Ahuriri. There are several key indicator species such as Tohorā and Kororā.

Below are the results of each of the Tohu Whāiti associated with this Tohu Matua. These Tohu Whāiti collectively inform the overall health of this Tohu Matua.

For each Tohu Whāiti we score qualitative and quantitative indicators called Pātai Inenga, we use these score to determine the health of each Tohu Whāiti. The ratings below are on a scale of 0 to 10, with 0 being very weak and 10 being very strong.
