Biomass assessment of the Mau Forest Ecosystem (MFE) was done as part of Kenya’s greenhouse gas inventory. Trans Mara and Mount Londiani forest blocks representing extremes of
vegetation types in the MFE were selected for ground data. Based on canopy
closure, four forest strata were identified as very dense, moderately dense,
open and bamboo. In each stratum, 5 clusters each with 4 plots measuring 30 m × 30 m were located.
Big trees (D1.3 ≥ 10 cm) were measured per species for diameter at
breast height (D1.3) in the whole plot while height was measured for
every 5th tree. Poles (10 cm > D1.3 ≤ 5) were measured
for D1.3 in a 10 × 10 m concentric
sub plot. Saplings (5 cm > D1.3; ht ≥ 1.5 m) and seedlings (ht <
1.5 m) were enumerated per species within 5 × 5 m and 2 × 2 m concentric sub
plots, respectively. Data were recorded in a Personal Digital Assistant (PDA)
and quality checked with Open Foris Collect software. Allometric equations that
have been used for similar vegetation in Kenya were used to relate D1.3 and height with biomass. The tree data were uploaded to
