The best way to regenerate a mangrove stand at the least cost is to encourage reproduction in the period before the final harvest by thinning and by minimizing damage to young plants during harvesting. Large concessions in Indonesia require felling of trees down to a stem diameter of 7 cm in 50 m wide strips interspaced with 20 m undisturbed strips in a proposed 20-year rotation.

Growth rings and parenchyma are indistinct.  |  Long-term, multiple-use management plans have to be developed and implemented to ensure sustainable use of the remaining resource. Keywords: R. apiculata is slightly more common than R. mucronata to which it is closely related. As thinning is a commercial operation, its timing, as well as the selection of tree species and stem diameter are influenced by market demand. Current rotations vary from 15 years (in firewood plantations in Thailand) to 20-30 years, but may be even shorter. doi: 10.1371/journal.pone.0236319.

Felling of R. apiculata for poles is essentially a thinning operation in which straight pole-sized individuals are cut. Seedlings may retain their viability for several months. This process involves selecting a well-formed tree and felling all pole-sized trees around it within a radius drawn by a stick 1.2-1.8 m long. Tamai, S. & Iampa, P., 1988.
