Deforestation statistics for New Zealand
Tree cover loss data for New Zealand
"Tree cover threshold" is used for defining the tree cover area. For example, 75% includes only areas with more than 75% tree cover, whereas 10% includes all areas with more than 10% tree cover. 75% tree cover reflects a dense canopy.

Biomass and land use carbon emissions data for New Zealand
"Tree cover threshold" is used for defining the tree cover area. For example, 75% includes only areas with more than 75% tree cover, whereas 10% includes all areas with more than 10% tree cover. 75% tree cover reflects a dense canopy.
