Abstract:

The dry forests and woodlands of the northern Kalahari are of great importance for the local inhabitants of the eastern Kavango, Namibia. But large areas of these forests are burned down annually by forest fires. These forest fires occur naturally in these forests, but the frequency altered. More frequent fires result in less time for vegetation to regrow. The wood production is important in these forests, this study aims to (1) determine if there is a short term variation in tree composition and tree growth in State and Community forest, (2) if young and old trees are more susceptible to the impact of forest fires and if the fire frequency has a negative impact on the basal area and diameter distribution (3) determine the number of fires that affected the sample sites in the last 15 years. In two different forests, Community and State forest, plots were sampled. In each forest 33 plots were sampled. The data of 2015 was compared with the data collected in 2014 by a group of students. The results show that there is no change in stem number, basal area and standing stock on short term. There is an effect of the forest fire on the condition of the trees. The damage inflicted by fire rose significantly. No change in diameter composition was found. This study found no evidence that the forest fires decreased the basal area on short term. Burned area products and LANDSAT images showed that the forests knew forest fires every two years in the last 15 years. The plots in Community forest knew a higher average fire frequency, although it wasn’t proven significantly. Only State forest had a single period of four years without forest fires. Keywords: Forest fire, woodlands, vegetation, fire frequency.
