The history of wild and cultivated plant diversity in Uganda is reviewed,taking forest species and bananas as examples. Palynological research into past human influences on forests is reassessed. The evidence suggests that crops were first introduced into the country at about 1,000 BCE,farming communities practicing slash and burn agriculture started to significantly influence the floristic composition of forests during the 1st millennium BCE and there was a major episode of forest reduction at about 1,000 CE related to socio-economic change. Bananas were probably introduced in the early centuries CE. The colonial era from 1894 saw the introduction of new concepts of land ownership and the establishment of forest reserves and agricultural stations. Forests and banana diversity are currently under threat,Uganda having a very high rate of deforestation and endemic banana varieties proving susceptible to introduced pests and diseases. It is suggested that,under these circumstances,conservationists take an opportunistic approach to field engagement,making use of favourable local conditions as they arise. Partnerships should be sought with elements of society concerned with sustainable use,provision of ecosystem services and cultural survival to widen the social base of plant conservation. International organisations involved in conservation of plant genetic resources and wild plant species should collaborate with one another to develop the conceptual basis of plant conservation,to make it more relevant to countries like Uganda.

The cultural universe is sometimes confusing,surprising and murky,so many cultural maps get drawn,discussed and envisioned.A study was undertaken around Mabira Forest Reserve in central Uganda to identify the trees and shrubs culturally managed on-farm,assess the cultural practices of forest and tree system management and determine the relationship between farmer gender and forest and tree system *** engaged 203 farmers in focus group discussions and semi-structured interviews to collect *** data were jointly evaluated with farmers;quantitative data were analyzed in SPSS *** results showed a high likelihood for involvement of local people in tree or forest management for economic gain,as timber and fast-growing species were highly *** and medicinal species were also regarded as important,suggesting high prospects of integrating them into the local farming system or protecting them in the *** cultural practices(including rituals,trenching,bark slashing,ring barking,spot weeding and use of organic manure and pesticides)of forest and tree system management were ***,their knowledge was mixed and unclear about distinct cultural and supportive arrangements for natural forest and tree *** gender was not a significant cultural attribute for knowledge of the forest and allied tree system management,age substantially affected farmer propensity for various timber *** farmer’s family size influenced the collection of tree wildings and *** encourage considering gender disparities and livelihood needs including income,during selection of cultural practices for forest and tree restoration.

Infraspecific Delimitation of <i>Acacia senegal</i>(Fabaceae) in Uganda

引用

American Journal of Plant Sciences 2011年第3期2卷 345-353页

作者： John Wasswa Mulumba esezah kakudidi 不详

The wide variation in Acacia senegal has presented taxonomic uncertainties and unresolved contradictions in previous studies. In this study numerical taxonomic principles and multivariate analysis (UPGMA PCoA and PCA) were used basing on 69 characters derived from growth form, branchlets, leaves, flowers, pods and seed. Three taxa, namely;variety senegal, leiorhachis and kerensis have been discerned and described significantly improving the delimitations of previous studies. The wide variation within var. senegal has been split into three recognizable variants and that of var. leiorhachis into two. The most important characters for differentiating the taxa include leaf breadth and length, pinna length and its ratio to pinna breadth, number of leaflet pairs, petiolar gland shape, petiolar and rachis gland size, stem and branch bark texture, stem and branchlet colour, under-bark colour for stem and branches, pod apical shape, growth form, crown shape, and prickly state of leaves. An identification key has been constructed which, for the first time, can be used to assign herbarium specimens to their respective taxa.
