The aim of the implementation of demonstration activities (DA) is to test and develop methodologies, technology and institution of sustainable forest management that endeavor to reduce carbon emission through controlling deforestation and forest degradation, as well as carbon enhancement. As mandated ini Decision 1/CP.13 of the Bali Action Plan, how to develop a national  MRV  that  meet  international  standard  and  cost  efective,  need  to be solved. In general the necessary aspect needed for MRV can be seen in Table 1.

PSP for Continuous Forest Inventory and  Measurement

Forest inventory refer to the inventory for determining growth by repeated inventories of permanent sample plots (PSP). For ground based inventory, permanent sample plots  (PSP) measuring at 20 x 100 meter has been applied for  MBNP. A total of 40 PSPs representing each zone within MBNP, and land use category according to IPCC has been made. Table 2 shows the data from forest inventory in term of dominant tree species, and associated variables needed for carbon accounting.

Table 2. Data of Dominant Tree, Soil, Underground and Litter of PSPs

PSPs are designed for:

• Supporting data and information for  the  purpose  of  ground truthing to backed up wall-to wall mapping using sattellite images,
• For this activity, at total of 40 PSPs have been made that represent  all zones in MBNP, consisting: 19 PSPs are located in nucleus zone, 16 PSPs are in forest zone, 3 PSPs are located in rehabilitation zone, 1 PSP is placed in buffer zone, and 1 PSP is in intensive utilization zone.
• To apply MRV principle, carbon  measurement  of  PSPs  are refered to IPCC Guideline that measure 5 carbon pools namely above ground biomass, below ground  biomass, necromass, litter and soil.  In this activity, initial  measurement  has  been  2-3 years reportable  National Communication Updated Inventory  made to identify carbon pools in every PSP consisting of above ground biomass (tree, pole and  undergrowth), litter (non woody necromass), and soil.
