Abstract

Moss is an important component of the tropical forest that plays a role in the balance of water and the forest's hara cycle. Moss growth is largely affected by temperature, humidity, light intensity, and pH. The study aims to identify the different types of moss plants along the Mutis mountain trail, the Mutis Timau wildlife preserve.Research was made along a Mutis mountain trail with three zones at the foot of Mutis, first field and second field. Each zone (station) was set up with two plots on the right and left side of the trail measuring 15 x 15 m2 across the plot 10 m (5 meters to the left of the track and 5 meters to the right of the track). The total plots at each observation station are four plots with a total of 12 plots. Sampling was carried out by photographing the moss found first, then taking the moss sample by scraping the moss colony and putting it in a sample bottle. Identification of moss samples was carried out based on their morphological characteristics such as color, stem shape (thallus), tip shape and leaf edges, and spore shape. Based on the identification results, the morphological characteristics of mosses are determined at the taxon level. The data obtained were analyzed qualitatively by explaining the taxonomy of the moss plant species found. Data will be displayed in the form of tables/figures. Based on the results of the study, there were 11 species of moss from 8 families. Nine types belong to leaf mosses (Bryopsida) which include Dichodontium Pellucidum, Leucobryum Albidum, Dicranum Scoparium, Leucobryum Javense, Kindbergia Praelonga, Isothecium Myosuroides, Pyrrhobryum Spiniforme, Hypnum Cupressiforme, Aulacomnium Palustre. Meanwhile, two types are classified as liverworts (Marchantiophyta), which include Jungermannia hyalina L, and Lejeunea cavifolia. The most families found were the Dicranaceae family which belonged to the Bryopsida class. The types of moss found generally live on weathered wood substrates and trees. The abiotic factors found in the mountain foot zone include temperature 24 ᵒC, humidity 62%, soil pH 7.0, normal soil humidity and normal light intensity. In the first field zone’s temperature is 27 ᵒC s, humidity is 54%, soil humidity is 54%, soil humidity is 54%, soil humidity is normal and light intensity is high, while in the second field zone’s temperature are 20 ᵒC, air humidity 71%, Ph soil 7.0, soil humidity is dry and light intensity is low.
