摘要

Rorya is one of new districts in Tanzania established in 2007. The district is a reflection of typical rural life in Africa South of Sahara where rural communities inhabiting dry woodlands and dependent on natural resources for their sustenance do not consider indigenous tree species as valuable resources of income. The study was conducted in the low lands of Rorya district-Tanzania to assess contribution of wild Acacia species for sustenance among rural communities. Ethnobtanical survey and standard sapling procedures were used for data collection and description of Acacia distribution patterns. Distribution and diversity of Acacia species is affected by multiple factors some of which could not be addressed by the arithmetic models employed in this study. Of all the sampled Acacia species, A. seyal ranked topmost as potential tree resource for a wider local and cross border market. Unlike other sampled Acacias, A. seyal has comparatively rapid biomass turnover within a short period. Density of A. seyal is much higher in swampy black cotton soils. Despite the economic potential of the species, significant proportion of Acacia woodlands is cleared annually for charcoal. Though Acacia seyal stumps coppices readily, combination of clearing and over grazing can convert the Acacia woodland to typical grasslands within a shorter duration of 20 years. At the same time, there is neither a conservation guideline nor land tenure arrangement in place for sustainable conservation. The study is recommending urgent legislative and land tenure reforms to control the current free access and encroachment that has nastily denuded the wood lands. Acacia being good source of pollen, commercial placement of bee hives is advocated as a supplementary economic activity in parallel with selling of wood fuel.

SEYAL排名最大的当地和跨境市场的潜在树资源。与其他采样的金合欢，A.Seyal在短时间内有相对快速的生物量营业额。 A. Seyal的密度在沼泽黑色棉花土壤中要高得多。尽管物种的经济潜力，但每年为木炭清除林地的大量比例。虽然Acacia Seyal Stupps Coppices容易，但清除和放牧的结合可以在20年的持续时间内将合欢林地转化为典型的草地。与此同时，既没有保护指南，也没有用于可持续保护的土地存款安排。该研究推动了紧急立法和土地系列改革，以控制目前的自由进入和侵占，却落下木材土地。金合欢是花粉的好来源，蜂荨麻疹的商业安置被提倡作为销售木材燃料并行的补充经济活动。
