The degree of harvesting on private land was relatively low, with the majority of trees having been harvested at rates of less than 10 % of the stem below 2 m. Despite this, ringbarking had occurred (4 %). The basal diameters and heights were significantly lower in the protected population than in the harvested one, suggesting that over time elephant impact was the more severe disturbance. Acacia xanthophloea exhibited high resilience to disturbance, with all the elephant damaged trees and harvested individuals surviving. However, the mean bark thickness measured in local markets (6.3±1.4 mm) was significantly lower than that measured in either the harvested (12.4±1.0 mm) or the KNP (10.3±0.8 mm) populations. As harvesters tend to select the largest individuals in a population to maximise their financial returns, this could mean that smaller individuals are being harvested, and/or bark is not being given sufficient time to grow back after harvesting. Acacia xanthophloea outside protected areas thus need to be monitored and the management improved, preferably in conjunction with the resource users. In addition, traditional healers, those selling medicinal plants and other members of the community need to continue to be encouraged to cultivate this fast growing species.]]> Fri 10 May 2024 15:56:09 SAST ]]> The use of and trade in indigenous edible fruits in the Bushbuckridge savanna region, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43826 Fri 10 May 2024 14:16:00 SAST ]]> Direct use values of secondary resources harvested from communal savannas in the Bushbuckridge lowveld, South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43875 Fri 10 May 2024 14:15:16 SAST ]]> Valuing South Africa's savannas: Methodological Issues https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43816 Fri 10 May 2024 14:14:02 SAST ]]> The role of land-based strategies in rural livelihoods: The contribution of arable production, animal husbandry and natural resource harvesting in communal areas in South Africa https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43755 Fri 10 May 2024 14:13:03 SAST ]]>
