Habitats: Hirudo medicinalis was found in shallow stagnant lowland water bodies with abundant vegetation, stable water levels, and presence of amphibian and mammal hosts for juveniles and adults, respectively. All localities were in rather temperate climatic conditions.
Status: Hirudo medicinalis is a critically endangered species in the Czech Republic ( Schenková & Košel 2005) due to intensive agri- and aquaculture in the country, which has resulted in extensive destruction of natural wetlands by drainage and flood-control management. Further loss of critical habitat for this species has resulted from intensive fishery and recreation in the few remaining unaltered wetlands, ponds, and small pools in the country. Based on authors’ monitoring experiences, the intensive mud removal by heavy machinery in the Czech Republic has had destructive impact on H. medicinalis populations. Isolated pools that historically supported populations of medicinal leeches have failed to yield specimens after mud removal operations have been conducted. Recent distributional records for this species in the Czech Republic have been limited to only a few localities in southern and middle Moravia and southern Bohemia.
