DIVERSITY OF MOSSES IN PHU KRADUENG NATIONAL PARK, LOEI PROVINCE

Abstract

The study of mosses diversity in Phu Kradueng National Park, Loei Province was explored from December 2014 to December 2016. The samples were collected along the 6 natural trails. A total of 501 samples were identified into 30 families, 55 genera, 100 species, 5 subspecies, and 9 varieties. Three families of mosses namely Sphagnaceae, Fissidentaceae, and Leucobryaceae were common families which included 11, 9 and 7 taxa, respectively. Additionally, the most common microhabitat was saxicolous with 45 species. The second and third common microhabitats were terrestrial and corticolous with 43 and 37 species, respectively. Additionally, there are 4 species which have not been recorded to Thailand, viz. Leptopterigynandrum decolor (Mitt.) M. Fleisch., Octoblepharum pocsii Magill & B.H. Allen, Pterobryopsis tumida (Dicks. ex Hook.) Dixon and Trachyphyllum touwianum W.R. Buck. Description of all species, ecological data, geographical distribution and photographs were prepared. Key to families, genera and species are constructed. The dry specimens are deposited at Professor Kasin Suvathabhandu Herbarium, Department of Botany, Chulalongkorn University (BCU) and Forest Herbarium, Department of Natural Park, Wildlife, and Plant Conservation (BKF).
