Throughout Borneo, all the known extensive, dense stands of Agathis have been heavily exploited and
some have been exhausted. It is likely that all that now remain are scattered small pockets and solitary
trees. The exploited stands are around Sampit and Tanahgrogot, Kalimantan; near Tawau, Sabah; and
at Badas, Brunei. There has in the past been considerable collection of Manila Copal, especially in
Sarawak, but this has now ceased.
