Mount Merapi National Park Authority (Balai TNGM), in collaboration with the Faculty of Biology at Universitas Gadjah Mada (UGM), held a three-day training on collecting distribution and population density data for five taxa using environmental DNA (eDNA) techniques on November 3-5, 2026. Ten Balai TNGM staff took part: eight forest ecosystem controllers and two forest police officers.
The training aimed to build staff capacity to design, carry out, and interpret eDNA-based biodiversity surveys as a complement to conventional monitoring. eDNA detects species from genetic material left in water or sediment, without capturing animals. The approach is non-invasive and well suited to hazardous terrain across the park’s 6,607.52 hectares.
The program focused on two common weak points: the quality of field sampling and the interpretation of results. Day one, held at the park authority’s meeting room and in the field, covered eDNA fundamentals, sampling design, and hands-on sample collection and preservation, contamination control, and chain of custody. Day two, at UGM’s Animal Systematics Laboratory, covered the path from sample to data, reading metabarcoding tables, diversity analysis, and the limits of conclusions that can be drawn for management. Day three consisted of DNA extraction, qPCR, and data analysis practice.
Participants worked in two groups of five, with about 40 percent of training time devoted to guided practice.
The training set targets of at least 80 percent of participants passing the practical sampling assessment, and the drafting of a concise field-ready eDNA sampling SOP and a one-year eDNA monitoring plan.
The activity supports Sustainable Development Goal (SDG) 15, Life on Land. It equips field staff with a non-invasive method for monitoring biodiversity, helping the park gather species-presence data in a more standardized way. The partnership with a university also contributes to SDG 17, Partnerships for the Goals. Long-term impact will depend on whether monitoring continues after the training.
