Marchantiophyta di Kawasan Hutan Batang Toru Blok Barat Sumatera Utara

Abstract

Mosses are a group of low plants and a part of biodiversity that has not received much attention. One area of North Sumatra that has never been reported on liverwort data is from the West Block Batang Toru Forest. This research was conducted to produce a list of the types of liverworts (Marchantiophyta) in the Batang Toru forest area, West Block, North Sumatra and to make a distribution map. The method used in collecting moss plants is an exploratory survey method, namely by exploring all the existing paths in the West Block Batang Toru forest. The samples obtained were photographed, collected and observed and recorded directly in the field into a note book. Moss specimens were collected dry and wet and identified and stored at the Medanense Herbarium (MEDA) Biology Study Program, Faculty of Mathematics and Natural Sciences, University of North Sumatra. Specimens were identified using identification keys and species descriptions from various literatures. The results of research conducted in the Batang Toru Forest, West Block, North Sumatra, found 10 families consisting of 25 genera, 107 species. The largest family is: Lejeuneaceae (13 genera, 32 species), followed by Plagiochilaceae (2 genera, 21 species), Radulaceae (1 genus, 17 species), Lepidoziaceae (3 genera, 16 species), Frulllaniaceae (1 genus, 12 species). species), Lophocoleaceae (1 genus, 5 species), and the families that were least found were Calypogeiaceae (1 genus, 1 species), Lepicoleaceae (2 genera, 1 species) and Trichocoleaceae (2 genera, 1 species). In this study, 25 new record species were found for Sumatran liverworts. The results of this study have been partially published in the Scopus Q3 indexed international journal entitled "The family Plagiochilaceae (Marchantiophyta) in Batang Toru Forest, North Sumatra, Indonesia" and have been disseminated in Scopus indexed international proceedings entitled "The Liverworts Family Lepidoziaceae ( Marchantiophyta) In Batang Toru Forest, North Sumatra”
