Abstract
The state nature complex (landscape) nature reserve of regional importance “Lekshmokh” (Arkhangelsk region) was created on June 14, 2019. It adjoins the borders of the Kenozersky National Park. Its area is 25248.7 ha. The watershed territory of the reserve is extremely important for the ecological balance of the ecosystems of the Kenozersky National Park and the drainage basins of the Onega, Kena, Lacha, Lekshmozero and Kenozero lakes. During the course of their development, the marshes of the reserve and the forest-bog complexes located inside them and framing them formed a bog system unique to the Kargopol region in terms of floristic diversity. Until now, the lichenobiota of the Lekshmoh reserve has remained virtually unexplored. The purpose of this study is to study the lichens of the Lekshmokh reserve as important components of biota. During the primary survey of the State Nature Complex Lekshmokh reserve, 96 species of lichens were noted. For each species, abundance is given on a 5-point scale. Among the lichens of the reserve, two species from the Red Book of the Arkhangelsk Region are noted: Bryoria fremontii and Lobaria pulmonaria. A large number of types of indicators of air purity are growing in the reserve: Usnea, Bryoria, Evernia, etc. This indicates the ecological value of the reserve, located away from industrial centers. Based on the reserve, a background environmental monitoring system studies are possible.
