Records of rare and protected species of aquatic plants in the Kostroma and Vologda regions (results of research in 2022-2024)

Based on floristic surveys conducted in the Kostroma and Vologda regions between 2022 and 2024, data on 69 newly recorded habitats for 13 rare species of aquatic and coastal-aquatic plants, including those listed in regional Red Data Books, are presented. For 3 species requiring monitoring in the Vologda region, 17 new locations were discovered. Based on the large number of finds of Utricularia minor and Potamogeton obtusifolius in the Kostroma region and Carex pseudocyperus in the Vologda region, it is recommended to change the status or be excluded from the Red Data Books.
