| PERIMETER_OF_CIRCLE |
This is the perimeter (in metres) if the area of the kahikatea patch was a perfect circle. PERIMETER_OF_CIRCLE = 2 * 3.14195 * sqrt(area_sqm)/3.14195) |

| SHAPE_INDEX |
Calculated as ACTUAL_PERIM_M / PERIMETER_OF_CIRCLE. For example if this has a value of 2 then the patch has a perimeter that is twice as long as if the patch was a circle. |

| MIN_DIST_TO_INDIG_OVER_25HA |
This is the minimum distance to the nearest patch of indigenous vegetation that is over 25 ha in size. The vegetation layer that the kahikatea layer is compared to was prepared as follows: Bioveg 2012 WHERE GEN_VEG = 'Predominantly Indigenous' was combined with the kahikatea layer. All combined areas where dissolved if they were contiguous. The dissolved layer was filtered to indigenous patches that were greater than 25 hectares in size in order to calculate this attribute. |

| INDIG_FOREST_IN_1KM_OF_PATCH |
This is the area of indigenous forest that is within a 1 km buffer zone of the kahikatea patch. Note that the 1 km buffer zone does not include the area of kahikatea patch itself. |

Y |
N |
| NEARBY_INDIG_HABITAT_PCT |
The percent of the buffer zone that is in indigenous forest. NEARBY_INDIG_HABITAT_PCT = (INDIG_FOREST_IN_1KM_OF_PATCH / BUFFER_AREA_HA) * 100. Note that BUFFER_AREA excludes the area of the kahikatea patch itself. |
