Selected Papers from the Rhinoceros Conservation Workshop, Skukuza, Kruger National Park,31 August – 4 September 1988 The conservation plan for the black rhinoceros presents specific aims and management guidelines for the conservation of the African black rhinoceros Diceros bicomis in the Republic of South Africa, the TBVC states and Namibia. The adoption of this plan, and the application of the strategies described therein (managing existing populations, establishing new populations and aspects of captive breeding) by the relevant conservation authorities should enhance the survival prospects of this species, both in the region and globally.

In South Africa, a filarioid infestation has been associated with lesions in the skin of the black rhinoceros (Schulz and Kluge, 1960). Similar lesions had been reported earlier from Kenya, as consistently occurring in these animals but their aetiology was unknown (Spinage, 1960). Recently the opportunity occurred to examine lesion material from four black rhinoceros located in the Royal Tsavo National Park Kenya. From this material adult helminths were recovered and identified (Round, 1964), and further pathological studies made. In addition, one rhinoceros showed evidence of an otitis.

Stem Mortality

Abstract:One manner in which elephants utilize trees is by removing their bark. This type of utilization is concentrated on the largest trees in the landscape. The role of bark removal in increasing the vulnerability of large trees to fire and the mechanism through which fire damage is mediated were investigated in Kruger National Park, South Africa, by experimentally removing bark and burning Acacia nigrescens stems with diameters ranging between 30 and 68 mm. Also, field surveys were conducted subsequent to natural fires in order to investigate mortality patterns of large trees with dbh greater than 15 cm with bark removed by elephants. An increasing probability of mortality was associated with increasing amounts of bark removal but only if trees were burned. When trees had bark removed but were not burnt, simulating damage only to cambium and phloem, none of the 12 treated stems died in the 4-mo period over which the experiment ran. Moreover, low levels of cambium damage were detected in large burned stems. This suggests that bark removal increases fire-induced xylem damage and that this damage contributes towards stem mortality. In a survey of 437 large trees, bark removal by elephants was frequent on large stems (44%) and larger trees have greater amounts of bark removed. Post-fire mortality of large trees was significantly associated with increasing bark removal and stem diameter. These results indicate that bark removal by elephants increases the vulnerability of stems to fire, resulting in mortality of large stems otherwise protected from fire.

Abstract. Organic matter-mineral associations stabilize much of the carbon stored globally in soils. Metastable short-range-order (SRO) minerals such as allophane and ferrihydrite provide one mechanism for long-term stabilization of organic matter in soil. However, ancient and highly weathered soils that cover a large fraction of land area lack SRO minerals. Here we evaluate the role of different minerals on the amount and turnover time (TT) of carbon in a field setting designed to minimize the role of SRO by taking advantage of multiple lithologies in Kruger National Park, South Africa. Density separation demonstrated that most of the C was associated with minerals, even in surface soils. A parallel separation of clay-sized material demonstrated that 9–47 % of the organic C in these soils was stabilized by clays. Organic C associated with clay-sized material had average TT of 1020 ± 460 years in surface soils. The mean TT of this clay-associated C increased with depth and with fraction of total clay that was smectite. Because the C associated with smectite clay was so old, the amount of smectite (2 : 1 clays) controlled the age of bulk soil C across Kruger landscapes. The TT of the majority of soil C – not stabilized by clays – was much shorter, 190 ± 190 years in surface horizons. We suggest that this faster component reflects timescales of weaker C stabilization by crystalline Fe and Al oxyhydr)oxides and kaolinite (1 : 1) clays, as well as LF fractions not associated with minerals. Thus, bulk or HF carbon integrates C stabilized by mechanisms with inherently different TT, something that is often inferred from radiocarbon measurements. While SRO mineral concentrations were very low in these soils, the soils with most SRO had very high C content but also very young C. In other environments, SRO can be very stable and sorb C on very long timescales. We hypothesize that the seasonal wetting and drying in the KNP may reduce the age of SRO minerals as well as the C associated with them. Across the varying lithologies and a precipitation gradient found in the KNP, we found mineralogy to be the most important explanatory factor for C content (related to crystalline Fe) and turnover time (related to the amount of smectite).
