LICHENS DIVERSITY SURVEY IN THUONG TIEN NATURAL CONSERVATION, HOA BINH PROVINCE
Keywords:Biodiversity, lichen, Nature Reserve (NR), Thuong Tien, Hoa Binh.
The study on lichen diversity in Thuong Tien Nature Reserve, Kim Boi district, Hoa Binh province was conducted in April 2022 through the establishment of a sampling survey route including 2 main routes. Research results at Thuong Tien Nature Reserve - Kim Boi district - Hoa Binh province have identified 41 species belonging to 9 families, 9 orders and 4 subclasses. In which the family with the largest number of species is Trichotheliaceae with 10 species (accounting for 24.4% of the total species), the Leprocaulaceae, Parmeliaceae and Opegraphaceae families all have only 1 species (accounting for 2.4% of the total species). The species discovered in the study area are all new species contributing to the lichen flora in Thuong Tien Nature Reserve. The biological indexes of species diversity (D' = 0,95) and biodiversity index (H' = 3,40) were assessed as relatively high. Regarding species richness: The species with the largest number of samples was Strigula nitidula with abundance (P% = 11,9%), the second one was Leprocaulon arbuscula with abundance (P% = 9.5%), followed by Porina distans with abundance (P% = 7,1%), Porina rubentior with abundance (P% = 5.95%). The remaining species had lower abundance (P% ≤ 3%).
