摘要: Highly humic lakes are typical for the boreal zone. These unique ecosystems characterised as relatively undisturbed habitats with brown water, high acidity, low nutrient content and lack of macrophytes. Current lake assessment methods not appropriate ecological highly because their properties differing human pressures acting on these ecosystems. This study proposes a new approach suitable status impacted by hydrological modifications. Altogether, 52 macroinvertebrate samples from 15 raised bog were used to develop method. The studied located in bogs at central eastern parts Latvia. Altered water level was found main threat since no other established. A multimetric index based abundance, littoral profundal preferences, Coleoptera taxa richness Biological Monitoring Working Party (BMWP) Score is suggested most tool assess quality lakes.
