Andualem Ayalew*, Derbie wudu, Gezahagn Getachew, Tegabu Redea and Hoaddis kasshun

The study was conducted in north wollo, south wollo and orimiya zone,in Eastern Amhara with an aim to assess

the resource potential of Acacia seyal in the selected sites. The data from the selected sites were collected using

point center quarter method. A total of 90 quadrates from nine study areas with plot size 50 m × 50 m, (22.5 ha)

were systematically located along each transect, 100 m apart, and was spatially captured with the aid of GPS. At

every sampling point, four quadrants (90°) were created, using the transect line and a line perpendicular to it.

Species composition Acacia seyal structure,and its regeneration status, at points along transects were taken to

analyze diversity and target species structure of the sites.The highest and least density of Acacia seyal ha-1 were

attained by Mehale mecharie (148) and Alene sefer (52).The highest shannon weiner diversity and species richness

was observed in Alene sefer (Kemessie).Acacia seyal structure in all study sites showed an inverted J shape except

Lastie gerdao(Gubalafeto).Therefore, Acacia seyal deserves immediate conservation and appropriate management

measures in order to get sustainable product and services from the species. Based on the results, awareness

creation on the values and management, study on the management options for firewood, fuel wood, charcoal

production and also investigation of gum production techniques of Acacia seyal for the sustainable use of the

resource are recommended.
