- The calculation of AAC was based on the PSP result for growth simulation.
- A repeated simulation runs have been carried out using different harvesting scenarios and their results were analyzed in terms of sustainability with estimated harvesting volume that will be achieved.
- It has a 25-year cutting cycle with an extractable of 9 to 15 trees/ha and an average harvestable gross volume of 30.0370 m3/ha.
- This calculation serves as a temporary indication of sustainable harvestable volume.
- Identification and monitoring of Endangered, Rare and Threatened (ERT) Species and their habitats and dynamism in sustainably well managed forest area.
- Non-Timber Forest Product (NTFP) like palm, bamboo, rattan, wild fruits and edible wild vegetable are present in the proposed FMU.
- Based on 15 PSPs, it has a total of 92 trees for DBHOB 30.0 cm and above with an estimated volume of 104.53 m3/ha, amongst which 77 trees are from DBHOB 30.0 – 49.9 cm with an average gross volume of 61.98 m3/ha whereas 24 trees or 42.552 m3/ha for 45.0 cm and above, and another 15 trees for DBHOB 50.0 cm and above with an estimated volume of 42.54 m3/ha respectively.
- FMU has the total of 15 ERT species of fauna with 21 species consisting of mammals, 2 reptiles and 1 insect.
- Rate of Annual Harvest:
- The average of harvestable yields within the research PSP is 42.91 m3/ha, derived from high density and low density of productivity areas based on fair representation of PSPs.
- The preliminary growth calculation of Mean Annual Increment (MAI) is 0.4 cm/year and 1.7216 m3/ha/year. The basal area is calculated as 26.018 m2/ha.
- Allowable Cutting Area (ACA) is 1,443.64 ha/year.
- AAC is 29,743.3643 m3/year or MPL is 2,478.6136 m3 of production limit for the initial planning of this FMP.
- Production area – Mixed Hill Dipterocarp Forests for the production of timber.
- Conservation area – undisturbed and partially disturbed which would serve as reference as continuous in research studies, refuge and breeding sites, as well as timber tree seed production and conservation of genetic diversity.
