神圣的树林，有些有几个世纪的历史，可能对坦桑尼亚一些植物物种的保存做出了贡献。这导致自然资源保护主义者考虑是否可以将圣林用于原地保护。研究人员对坦桑尼亚中部Wanyamwezi乌干达酋长的8个神圣树林进行了调查，这些树林代表了6-300年历史的墓葬遗址，并将木本物种丰富度和分类多样性与国家管理的森林保护区的森林地块进行了比较。圣林园占地面积虽小，但其木本物种丰富度和分类多样性均高于国家管理的森林保护区。森林样地与圣林的物种相似性指数为45%，表明圣林对苗波林地生物多样性的就地保护有贡献。一些木本物种在森林中没有出现，这也表明小树林是一些物种的避难所。对所有现存的圣林进行清点可以提供关于它们在就地保护中的作用的重要资料。为了促进以社区为基础的生物多样性保护，政府应该宣布圣林为保护区，并将其纳入现代保护体系。
Sacred groves, some as old as several centuries, may have contributed to the preservation of some plant species in Tanzania. This has led conservationists to consider whether sacred groves could be used for in situ conservation. Eight sacred groves of the Ugunda chieftaincy of the Wanyamwezi in central Tanzania representing burial sites that varied from 6–300 years old were inventoried to compare woody species richness and taxonomic diversity with those of forest plots in a state managed Forest Reserve. Although they occupied a relatively small area the sacred groves had greater woody species richness and taxonomic diversity than the state managed Forest Reserve. The forest plots and the groves shared a species similarity index of 45%, suggesting that the sacred groves contributed to in situ conservation of the miombo woodland biodiversity. Some of the woody species were absent in the forest plots, also suggesting that groves served as a refuge for some species. An inventory of all existing sacred groves could provide important information on their role in in situ conservation. In order to promote them for community-based conservation of biodiversity the government should declare sacred groves as preservation sites, and incorporate them into modern conservation systems.
