The open woodlands in the northeast of Namibia are at the southern edge of the Miombo ecoregion. They are characterised by a few canopy species of which Pterocarpus angolensis is considered the most valuable timber wood in the country. Despite its economic importance, there are no estimations for the growing stock of the species on a national level. It is therefore hard to demonstrate that there is not enough wood to sustain a timber economy and that the species is threatened by global climate change or by high fire frequency. There are forest inventory data and wood volume equations available on a regional and local level that allow to give rough estimates of the growing stock of Kiaat. An overview is made of the regional wood volume data for all species and for P. angolensis for the year 2000. The inventory area used for the estimate is four times higher than that used in forest resources assessments used in Namibia since 2000, and the mean wood volume for Namibia's forested areas decreased from 24.1 to 21.2 m 3 /ha. Mean wood volume of P. angolensis for all forested areas in Namibia, including regions where the species is not found, is about 1 m 3 /ha. Available wood volume equations are compared for P. angolensis with historical and recent data of the Kavango regions. Values vary between 11 and 19 m 3 /ha for the recent total wood volume per hectare. More data is needed to improve the estimates and to monitor changes, especially because the standard error of the mean volume estimates are high for P. angolensis. Assessing tree cover accurately and on a regular basis is one of the main challenges for the future. Forest cover in Namibia according to FAO is now about 8% but is based on linear extrapolations of data of 1993. An integrated method using field inventories with a national cluster-wise systematic grid in combination with remote sensing and other data appear the most efficient approach for future forest assessments.
