Abstract:
Infection with the cestode Spirometra spp. was studied in 2 populations of lions in the Serengeti and the Ngorongoro Crater in Tanzania, East Africa. These 2 lion populations lived in different habitats and were known to differ genetically: lions in the Serengeti were outbred, whereas lions in the Ngorongoro Crater were inbred. Faecal samples were collected from 112 individually known lions between March 1991 and November 1992. Over 60% of lions were infected and the median intensity of infection was 975 eggs per g of faeces. The distribution of egg counts was overdispersed. There was variability through time, though this was unrelated to seasons delimited by rainfall. There were no significant differences in levels of infection between age classes; cubs less than 9 months were already heavily infected. Sex and reproductive status did not have a significant effect. However, there were significant differences in intensities of infection between the Crater and the Serengeti populations – Spirometra spp. showed a higher level of infection intensity in the Crater population – with some variation between prides within these populations. Allozyme heterozygosity scores were available for a subset of 28 lions but were unrelated to levels of Spirometra infection. It was not possible to ascribe differences in levels of parasite infection to genetic rather than ecological factors.

Abstract:
Ngorongoro Conservation Area (NCA) is vital especially for black rhino conservation because it is one of the only two ecosystems in Tanzania that host native black rhino populations. However, the spatial-temporal distribution of rhinos in this ecosystem have not been assessed. The purpose of this study was to assess the temporal and spatial distribution of rhinos and factors responsible for the uneven seasonal distribution. The study was conducted in Ngorongoro Conservation Area (NCA) which is located at 3°12′S, 35°27′E during the wet (May-June 2015) and dry (August-September 2015) sampling periods. Road drives were conducted daily for a period of one month during each season to map the spatial distribution of the black rhino, and assess the relative abundance of its forage resources and diet selection. During each drive, the roadsides were inspected for the presence of rhinos, with stops being made each time an individual or group of rhinos is located. Results shows that the distribution patterns of the black rhino differed markedly between wet and dry sampling periods. During the dry period, rhinos were mainly concentrated in the crater slopes dominated by shrubby vegetation, swamps and along riverine areas of the crater. During wet season in there were more herbage material mostly preferred by black rhino in crater floor as most rhinos were sighted in these sampling areas. Human activities such as tourism infrastructure (lodges, campsites and roads) should be kept minimal to minimize disruption to rhino movement and habitat selection patterns and buffer zones be established within crater-community interfaces where human activities such as livestock grazing are strictly prohibited to ensure natural distribution ranges are maintained.

Abstract:
The Ngorongoro Crater is a volcanic caldera located within the Ngorongoro Conservation Area in Tanzania. The Crater comprises a flat grassland plain surrounded by steep, bushy walls. It contains extremely high densities of animals and is ecologically the central feature of Ngorongoro Conservation Area. The management of the Ngorongoro Crater has changed significantly in recent times, with cattle being removed and fire excluded about 30 years ago. A detailed vegetation assessment was carried out in the Crater floor by Herlocker & Dirschl in 1972. Since then noticeable changes in vegetation structure and composition, with associated changes in wild herbivore numbers have occurred. The original vegetation survey was repeated in this study as accurately as possible using similar point-based techniques in order to quartify changes and form a baseline for management decision-making and future monitoring. In addition to repeating the vegetation survey, the standing biomass was estimated using a Pasture Disc Meter with associated calibration equations. Data were summarised using multivariate classification and ordination techniques in order to delineate six Homogenous Vegetation Units (HVUs) which can be used for management and management planning purposes, define transects and HVUs in terms of dominant species, describe the main species in relation to their occurrence in different associations and determine the fuel load of the standing crop. A key grass species technique was developed for rapid assessment of the Crater rangeland by the Ngorongoro Conservation Area staff who only need to be familiar with the dominant species. Bush surveys using a point centred quarter technique were conducted along transects in two distinct vegetation types, namely the Lerai Forest and Ngoitokitok Acacia xanthophloea forests and the lower caldera scrub vegetation. The data collected from these transacts were analysed to determine density and composition of the vegetation in the various height classes and the overall structure of the vegetation communities, A range monitoring system in conjunction with a controlled burning programme has been developed to provide an objective means of managing the- rangeland of the Ngorongoro Crater. Data revealed that changes have taken place in the vegetation, with a trend towards dominance by taller grasses and dominance by fewer species. Lack of fire has probably contributed to these changes. Reincorporating fire in the crater is recommended.

Abstract:
Management of sub-Saharan protected areas is at its peak, with most countries having signed up to international conventions aimed at protecting the natural environment and collectively managing political threats that are likely to emanate from other states’ interest to harness cross-border environmental resources. These conservation efforts however are at a broader perspective that does not cater for the nuances at varying scales of environmental resources conservation and management. This article looks at the micro scale of resources management and assesses conservation of landscape at a protected world heritage area to illustrate an existing gap that needs to be addressed by accounting for each and every category of resources found in any protected landscape. To illustrate this phenomenon this article discusses insights from two protected areas of world heritage status in southern Africa: Ngorongoro Crater Conservation Park World Heritage site in Tanzania and Okavango Delta World Heritage site in Botswana.
