Keanekaragaman lumut sejati di Taman Nasional Gunung Merapi Sleman, Yogyakarta

Abstract

Mosses are a group of non-vascular plants. It accurs abundantly in tropical rain forest. Substrate type and the availability of substrate are important in affecting the diversity of mosses. Eruption of Merapi volcano Oktober 2010 have a great demages on the vegetation of Mount Merapi National Park. Many trees are burned and uprooted. The understory were covered by volcanic material. Mosses might have important roles in the secondary succession followed the vulcano eruption.This research aimed to record and describe the diversity of the mosses species in the secondary succession at the vegetation of the national park and to make identification key of the mosses. Samples were collected in three sites area sixteen month after the eruption in 2010, namely Pronojiwo, Gandok, and Kinahrejo. Purposive sampling method was used to record the diversity of mosses. In addition, quadratic sampling method was used to determine the dominant mosses in the successional process. Identified mosses were listed into a list. Total of 41 species of acrocarp and 4 species of pleurocarp mosses were found in the sites. Mosses diversity in Kinahrejo are quite similar to Gandok but it was different with Pronojiwo. Most mosses were found on terrestrial substrate, that are soil, sand, and rock. Trematodon conformis is a dominant pioneer mosses in the successional process of the national park.
