Architectural Application
Timber from dammar resin trees is not typically used for primary structural elements because the trees are exploited for resin rather than wood.
Dammar resin is used industrially in varnishes and finishes, incense, food glazing agents, and traditional medicines, making it an important natural extract resource.
Trees producing dammar resin can be part of tropical agroforestry and forest restoration systems and support biodiversity in native forests.
