Lichen is a mutualistic symbiotic organism composed of a fungus and an alga. As a composite life form, lichen plays vital ecological roles and holds broad potential for various applications, such as pharmaceuticals, food resources, and natural dyes. In an effort to support biodiversity research and environmental conservation, the Faculty of Biology at Universitas Gadjah Mada (UGM), in partnership with the Mount Merapi National Park (TNGM) Authority, conducted collaborative exploratory research to map the species diversity of foliose lichen in the TNGM region. Beyond enriching scientific data, this collaboration represents a concrete implementation of the UGM Faculty of Biology’s curriculum in producing excellent Bachelor of Science (S.Si.) graduates in Biology. Led by UGM Faculty of Biology lecturer Ludmilla Fitri Untari, S.Si., M.Si., the study involved three undergraduate students: Aan Nur Risla Wardana, Adha Nurkholifah, and Dwi Pramesti Wahyuningtias. The research aimed to reveal the species diversity of foliose lichen and examine the relationship between environmental factors and their abundance in the Mount Merapi area.
The study on foliose lichen comprised two main stages: field exploration and laboratory analysis, conducted from May to December 2026. Sampling was carried out on the southern slopes of Mount Merapi, specifically at Klangon Hill in the Cangkringan Resort and Deles Indah in the Kemalang Resort of Mount Merapi National Park (TNGM). These locations were chosen for their diverse mountain forest habitats, which offer high potential for foliose lichen growth. Field data collection utilized the cruising method paired with abiotic factor measurements, including light intensity, temperature, and air humidity. The collected specimens were subsequently identified at the Plant Systematics Laboratory, Faculty of Biology UGM, through morphological and anatomical characterization, simple spot testing for chemical compounds, and molecular-based identification.
This collaborative research also supports the achievement of the Sustainable Development Goals (SDGs), particularly in education, biodiversity conservation, and academic partnerships. The activity aligns with SDG 4 – Quality Education, through student involvement in field research-based learning. Students gained hands-on experience in sampling, species identification, environmental parameter measurement, and ecological data analysis. The study further supports SDG 15 – Life on Land, by documenting foliose lichen diversity to enrich biodiversity data in the Mount Merapi region. This information is expected to serve as valuable supporting data for future research on terrestrial ecosystems and biodiversity conservation efforts. Additionally, the collaboration between lecturers and students reflects the spirit of SDG 17 – Partnerships for the Goals, demonstrating cooperation in research execution, scientific skill development, and strengthening academic contributions to environmental studies.
