Abstract: In Belarus 16 habitats of relict species lake quillwort (Isoëtes lacustris L.) are registered. Lakes were studied in the period from 1972 to 2011. Populations of Isoëtes lacustris L. in the lakes differ with morphology of plants, abundance, frequency of occurrence, partial projected foliage cover. Development of populations of the spe-cies is limited by morphometric characteristics of lake hollow, hydrophysical and hydrochemical parameters of the environment. Evaluation of lake quillwort tole-rance to environmental conditions allows us to charac-terize lakes’ parameters as optimal for 4 lakes (Beloe, Luninets district; Bredno; Glubokoe; Cherbomyslo), non favorable, which has led to the oppression of the po-pulation and destruction of plants (Beloe, Gorodok district; Beloe, Myadel district; Svityaz’) and normal for 8 lakes. The most significant threats to growth of Isoëtes lacustris L. are changes in the lakes’ level, eu-trophication of lakes, alkalizing of water, mechanical destruction of plants.
