Tree volume means the volume of the entire tree comprising of the main tree trunk and branch wood.2 Tree biomass means the biomass of the entire tree comprising of the main tree trunk and branch wood.
3 Total number of trees in the sampled area is equal to AMean No. of trees/ha@ x ASize, in Ha@. For example, in West Tsumkwe District: 99 x 607,949 = 60,186,951 trees.,
Total volume of trees in the sampled area is equal to AMean tree volume m3/ha@ times ASize, in Ha@. For example, for Western Tsumkwe District: 17.8 x 607,949 = 10,821,492 m3.

In omusati Region, tree height includes Hyphaene petersiana (Makalani) and Sclerocarya birrea (Marura)6
In Oshana Region, tree height includes Sclerocarya birrea (Marura) and Diospyros mespiliformisAnnex II
