Fitness for purpose / limitations

This table indicates whether the dataset is suitable for different types of questions at different scales.

Note: Users should carefully consider their purpose as this dataset may not be suitable.

Operational Absolute Relative Screening/scoping
Block/farm Maybe Maybe Maybe Maybe
Multi-farms(5+) Maybe Maybe Maybe Maybe
Catchment No No Maybe Maybe
National/regional No No Maybe Maybe
Caveat(s) Forest sequestration rates based on the ETS Standard tables are accurate for operational use for forest owners with less than 100 ha in terms of NZU rewards, though not necessarily in terms of actual sequestration achieved. Other estimates are provided to give a sense of their likely order of magnitude but may differ by species and site.
