Mapping Intra-Species Stem Diversity in Gyrinops versteegii Across Sumbawa Island
Aug 11, 2026

Agarwood (Gyrinops versteegii), known locally as gaharu, stands as one of Indonesia’s most economically prized non-timber forest resources. Revered globally for its high-grade aromatic resin used in luxury perfumes, traditional pharmaceuticals, and religious ceremonies, top-quality agarwood resin can command market valuations exceeding USD 45,000 per kilogram.








Indonesia’s montane forests harbor a rich diversity of tree species, including Pasang (Quercus sundaica), a member of the Fagaceae family that plays an important ecological role while also providing valuable timber resources. Despite its significance, information on how this species is distributed and regenerates in natural forests remains limited.
