In an investigation conducted in the South and West Bohemian region the author paid attention to the incidence of the tick Ixodes ricinus and foci of tick-borne encephalitis in original plant communities. In Southern Bohemia in places of original communities of acidophil oak forests, oak-hornbeam woods and their mosaic combinations as well as combinations of flowers and beech forests and meadows and alder trees the author detected 93.5% of the breeding places of ticks. In Western Bohemia in original oak forests there were 97.2% breeding places of Ixodes ricinus. In other original plant communities, although influenced and partly altered by human activities--i.e. in highly located beech woods and pine tree woods and in damp communities--in peatbogs, meadows and grassland no ticks were found. Evaluation of a territory, based on plant and animal communities and typical species as their indicators, is a useful method as regards the prognosis of the prevalence of ticks or possibly foci of tick-borne encephalitis, as was demonstrated on the example of an uncommon focus of tick-borne encephalitis and tick-borne borreliosis on the upper Vltava river.
在一项针对南波希米亚和西波希米亚地区开展的调查中，作者关注了蓖麻硬蜱的发生率以及原始植物群落中蜱传脑炎的疫源地。在南波希米亚，在嗜酸橡树林、橡角树森林及其镶嵌组合的原始群落所在地，以及花林与山毛榉林、草地和桤木的组合区域，作者发现了93.5%的蜱繁殖地。在西波希米亚的原始橡树林中，有97.2%的蓖麻硬蜱繁殖地。在其他原始植物群落中，尽管受到人类活动的影响并部分发生了改变，即在地势较高的山毛榉林和松林以及潮湿群落（如泥炭沼泽、草地和草原）中，未发现蜱。基于植物和动物群落以及作为其指标的典型物种对一个地区进行评估，对于预测蜱的流行情况或蜱传脑炎可能的疫源地而言是一种有用的方法，这在上伏尔塔瓦河上一个罕见的蜱传脑炎和蜱传莱姆病疫源地的例子中得到了证明。
