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

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

  3. Forest Size determination Acacia-Comiphora woodland Juniperus-Podocarpus

  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. Main Plot (100 m x 100 m) Trees ≥ 30 cm DBH Sub plot (25 m x25 m) Trees 15-29 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 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).

  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 239.5 tons/ha. CO2:C molecular ratio (44:12) = 3.67
