1 REDD+ Project Area Juniperus-Podocarpus Acacia-Comiphora woodland

2 Definition & Demarcation of project boundary and Mapping stratum
Stratification - Altitude - Stocking Juniperus-Podocarpus Acacia-Comiphora woodland

3 Forest Size determination
LAND-COVER STRATUM TYPE AREA (HA) Juniperus-Podocarpus 6,000 Acacia-Commiphora 28,000 Juniperus-Podocarpus Acacia-Comiphora woodland

4 Cont.. Decision on Forest Carbon Pool to be Measured:
Available financial resources, Availability of existing data, Others Determination of the Type of Sample Plots ( Permanent or temporary) NB: example if Soil carbon is omitted during first carbon stock assessment (i.e. baseline), it has to be also omitted during the second and subsequent carbon assessments.

5 Cont.. Decision on the Shape and Size of the Sample plot (There are two types of plots – single plots of a fixed size or nested plots containing smaller sub-units of various shapes and sizes). Main Plot (100 m x 100 m) Trees ≥ 30 cm DBH Sub plot (25 m x25 m) Trees cm DBH Sub plot (10 m x10 m) Trees 2-14 cm DBH Sub plot (1 m x1 m) Litter, soil, shrubs, herbs < 2 cm DBH

6 Determination of Number of Sample Plots
Once the strata’s are identified and agreed on, the type of plots and shapes are decided, the number of sample plots required in each stratum must be determined. The decision on the number of plots depends on vegetation type, logistics, accuracy level, manpower and cost. The number of samples for each stratum is selected proportional to its size.

8 Juniperus-Podocarpus Forest
To determine the biomass, the Woody Biomass National Inventory regression equation for 798 weighed trees Reg. Model = (0.3658* DBH)+(0.1144*(DBH^2.2))  The overall mean stocking rate of above ground woody biomass (AGB) is 107 tons/ha. Using the below ground biomass (BGB) factor of 0.22 of AGB, mean below ground biomass is 23.5 tons/ha. With a biomass to carbon ratio of 0.5, total forest carbon stocks are 65 tons/ha and CO2 sequestered is tons/ha. CO2:C molecular ratio (44:12) = 3.67
