The potentials of enclosures in increasing woody
biomass regeneration(A case study of Begasheka
and Debrekidan watersheds, Tigray, northern
Ethiopia)
THE STUDY SITES The study was conducted in
Begasheka and Debreikidan watersheds, Tigray,
northern Ethiopia (Fig. 2)

species was found to be healthy in both

explain the variability in biomass (example from
Debrekidan watershed)
From the two watersheds, 45 plots with a radius
of 5.6 m were used in this study and laid down
randomly in the enclosures. Height, diameter at
stump height (DSH), diameter at breast height
(DBH), Crown diameter, number, identity and life
forms were recorded. Single tree-sampling method,
destructive, was used to estimate the above
ground woody biomass of each species. Sample
trees were cut, dried in oven to estimate their
moisture content and biomass.
RESULTS Summery Biomass produced in the Begasheka
and Debre-kidan were 6.86 ton/ha and 3.8 ton/ha
respectively. 745 individuals representing 30
species 731 individuals representing 19 species
were found in Begasheka Debre-kidan
respectively.
