Study of Bryophyte Diversity in The Glongsor Waterfall Area PuspoPasuruan Regency Studi Keanekaragaman Tumbuhan Lumut (Bryophyta) di Kawasan Air Terjun Glongsor Puspo Kabupaten Pasuruan

Abstract

Mosses (Bryophyta) play an important role as a component of ecosystems in maintaining environmental balance, particularly in aquatic areas such as waterfalls. This study aims to identify the diversity of moss species in the Glongsor Waterfall, Gondosuli, Puspo area; to determine the diversity index and importance value index of mosses in the same area; and to assess the potential of moss diversity research as a resource for biology learning. The study was conducted from December 2024 to March 2025. The research employed a descriptive-exploratory design using both quantitative and qualitative approaches. Field surveys were conducted using the transect line method and purposive sampling for sample collection. Moss identification was carried out at the Botany Laboratory, Biology Education, UNU Pasuruan, considering habitat, color, and substrate characteristics. The results revealed 13 species of mosses in the Glongsor Waterfall area, belonging to the classes Bryopsida, Marchantiopsida, Hepaticopsida, Polytrichopsida, Jungermanniopsida, and Anthocerotopsida.
