齿形动物对人类的干扰特别敏感。他们的多样性相对于四种景观类型（人工林，公园，住宅区，工业区）沿着一条小河（Dorpspruit），流经彼得马里茨堡，南非，描述。利用CANOCO多变量分析软件包对个体物种与环境的关系进行了调查。鉴定了4种生物群落类型。分析还说明了城市、郊区和森林环境对蛇齿目动物的影响程度。多物种组合是良好的环境指标。个别指示种包括小绿鳄（Chlorolestes tessellatus）和红鳄（Crocothemis erythraea）。tessellatus是河流边缘和商业人工林之间原生河岸植被带最小宽度（约30 m）的良好指示物。这项研究表明，在水边和人工林之间应该有至少20米（最好是30米）的河岸带。这一发现与早期的研究结果相结合，得出了一个总体的保护管理建议，至少对南非的河流蜻蜓来说是这样。
Odonata species are particularly sensitive to human disturbances. Their diversity relative to four landscape types (plantation forest, parkland, residential area, industrial area) along a small river (the Dorpspruit) that runs through Pietermaritzburg, South Africa, is described. Individual species-environment relations were investigated using the multivariate analysis package CANOCO. Four biotope types were identified and characterised. The analysis also illustrated the extent to which the urban, suburban and forestry environments affected the Odonata species. Multispecies assemblages were good environmental indicators. Individual indicator species included Chlorolestes tessellatus and Crocothemis erythraea. Chlorolestes tessellatus is a good indicator of the minimal width (> 30 m) of the indigenous strip of riparian vegetation between the stream edge and commercial plantations. This study suggests that there should be a riparian strip between the water's edge and plantation trees of at least 20 m (preferably 30 m). This finding is integrated with earlier ones to arrive at a general conservation management recommendation, at least for dragonflies, for rivers in South Africa.
