ABSTRACT Selective timber harvesting in tropical rain forests is one solution to maineg conservation objectives while at the same time providing forest resources. Quantitative studies aimed at understanding the effects of selective logging on forest ecosystems can contribute to sustainable management designs which minimise the negative impacts of habitat alteration on wildlife. Estimation of changes.in primate density and patterns of habitat use in human modified habitats are useful indicators of impact. Using a comparative model, ecological and behavioural correlates of two groups of redtail monkeys (Cercopithenrs ascanius schmidtii) inhabiting primary and regenerating forest sites in the Budongo Forest Reserve, Uganda, were conducted. Observational data were collected on two groups of redtail monkeys over a six month period based on 135 horn of scan sampling data. One group ranged within an uniogged primary forest and the second group in a mixed forest selectively harvested in 1947 and 1952. Results revealed that redtail group densities were three times higher in the selectively logged habitat. Significant differences in habitat use pattems, as indicated by differences in plant diet and ranging patterns, were observed between the two study groups. Factors which best explain these differences include the higher densities of preferred redtail food trees and the increase in tree species diversity in the regenerating forest. This situation, advantageous to redtails, devebped in the logged forest due to the relatively low intensity of selective logging there and the trend towards C'ometra monodominance in the primary forest.

  • Impacts of Global Climate Change on the Phenology of African Tropical Ecosystems
    IMPACTS OF GLOBAL CLIMATE CHANGE ON THE PHENOLOGY OF AFRICAN TROPICAL ECOSYSTEMS GABRIELA S. ADAMESCU MSc by Research UNIVERSITY OF YORK Biology October 2016 1 Abstract The climate has been changing at an unprecedented rate, affecting natural systems around the globe. Its impact has been mostly reflected through changes in species’ phenology, which has received extensive attention in the current global-change research, mainly in temperate regions. However, little is known about phenology in African tropical forests. Africa is known to be vulnerable to climate change and filling the gaps is an urgent matter. In this study we assess plant phenology at the individual, site and continental level. We first compare flowering and fruiting events of species shared between multiple sites, accounting for three quantitative indicators, such as frequency, fidelity for conserving a certain frequency and seasonal phase. We complement this analysis by assessing interannual trends of flowering and fruiting frequency and fidelity to their dominant frequency at 11 sites. We complete the bigger picture by analysing flowering and fruiting frequency of African tropical trees at the site and community level. Next, we correlate three climatic indices (ENSO, IOD and NAO) with flowering and fruiting events at the canopy level, at 16 sites. Our results suggest that 30 % of the studied species show plasticity or adaptability to different environments and will most likely be resilient to moderate future climate change. At both site and continental level, we found that annual flowering cycles are dominant, indicating strong seasonality in the case of more than 50% of African tropical species under investigation.

  • Tree Species Selection for Buffer Zone Agroforestry: the Case of Budongo Forest in Uganda
    52 International Forestry Review Vol.10(1), 2008 Tree species selection for buffer zone agroforestry: the case of Budongo Forest in Uganda W. K. KASOLO and A. B. TEMU Nyabyeya Forest College, Private Bag Masindi Uganda and World, Agroforestry Centre (ICRAF) P.O Box 30677 Nairobi, Kenya Emails: [email protected] and [email protected] SUMMARY This paper highlights the importance of careful selection of tree species for use in buffer zone agroforestry, as a conservation strategy for threatened forest resources. A case study from the Budongo Forest buffer zone in Uganda is used to elaborate the process, where local communities applied a pair-wise ranking system to establish priority tree species and technologies for agroforestry. Maesopsis eminii, Vernonia amygdalina and Lasiodiscus mildbraedii were the top three species selected for integration into the buffer zone farms. Their selection refl ects the many good attributes experienced by farmers in the area, such as provision of timber, construction poles, and fi rewood. The most popular technologies were woodlots, boundary planting and shade trees (multistrata tree planting), in that order of priority. Areas for further research include an evaluation of the economic aspects of the species and technologies, on farm propagation and management protocols and markets for the tree products. Keywords: Buffer zone, Budongo forest, local communities, Agroforestry technologies, species selection Sélection d’arbres pour l’agroforesterie des zones-tampon: le cas de la forêt Budongo en Ouganda W. K. KASOLO et A. B. TEMU Cet article souligne l’importance d’une sélection précise d’espèces d’arbres en vue de leur utilisation dans l’agroforesterie des zones- tampons.

The project aimed to document the floristic diversity of the Angolan escarpment, a combination of general walk-over survey, plant specimen collection and sight observation was used to aid the characterization of the vegetation. Over 100 plant specimens in flower or fruit were collected within four identified vegetation types. The list of species in- cludes two new records of Guineo-Congolian species in Angola, one new record for the country and one potential new species. Keywords Kumbira forest, Guineo-Congolian, floristic diversity Introduction Angola lies almost wholly within the southern zone of tropical grassland, bounded by tropical rain forest of the Congo in the north and by the Kalahari Desert in the south (Shaw 1947).

  • Forest Tree Persistence, Elephants, and Stem Scars1
    BIOTROPICA 36(4): 505±521 2004 Forest Tree Persistence, Elephants, and Stem Scars1 Douglas Sheil and Agus Salim Center for International Forestry Research (CIFOR), P.O. Box 6596 JKPWB, Jakarta 10065, Indonesia ABSTRACT Sixteen percent of tree stems 10 cm diameter or greater recorded in seven 1 ha plots in Rabongo Forest, Uganda had stem damage attributable to elephants (Loxodonta africana). We propose four strategies that may help tree species persist under these conditions: repellence, resistance, tolerance and avoidance. We sought and found evidence for each strategy. Large, shade-tolerant Cynometra alexandri dominated basal area (often .50%) and showed severe scarring. Nearly 80 percent of stems were small pioneer species. Scarring frequency and intensity increased with stem size. Stem-size distributions declined steeply, implying a high mortality to growth rate ratio. Tree species with spiny stems or with known toxic bark defenses were unscarred. Epiphytic ®gs escaped damage while at small sizes. Mid-successional tree species were scarce and appeared sensitive to elephants. Savanna species were seldom scarred. Taking stem size- effects into account by using a per-stem logistic modeling approach, scarring became more probable with slower growth and with increasing species abundance, and also varied with location. Pioneer and shade-bearer guilds showed a de®cit of intermediate-sized stems. Evidence that selective elephant damage is responsible for monodominant C. alexandri forests remains equivocal; however, elephants do in¯uence tree diversity, forest structure, and the wider landscape. Key words: African semi-deciduous rain forest; bark damage; Cynometra alexandri; herbivory; Loxodonta africana; monodominant; species richness; succession; tolerance; Uganda.

These studies focus on species discovery and conservation through the Tropical Important Plant Areas programme. Methods – Normal practices of herbarium taxonomy have been applied to study the material collected. The relevant collections are stored in the Herbarium of the Royal Botanic Gardens, Kew, London and at the Limbe Botanic Garden, Limbe, and the Institute of Research in Agronomic Development – National Herbarium of Cameroon, Yaoundé. Key results – New species to science continue to be discovered from Mt Cameroon. Most of these species are rare, highly localised, and threatened by habitat destruction. These discoveries increase the justification for improved conservation management of surviving habitat.
