| dc.description.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” | en_US |
