Rangeland evaluation in the middle Awash valley of Ethiopia: II. Woody vegetation

Rangeland evaluation in the middle Awash valley of Ethiopia: I. Herbaceous vegetation cover

“…The low basal cover in some rangeland sites of the study districts (Mogassa, Samayu, Chopi and Bulga riverside) could also associated with high tree densities (Abule et al, 2007). The relatively better basal cover at Kolbayu and Degage than the other rangeland sites can be related to the fact that these rangeland sites are found at the junction between Awash-Fantale and Kereyu-Fantale districts where animals cannot graze as freely as they graze the other rangelands.…”

“…The decrease in grass production at Samayu and Mogassa, when compared to the other sites, could be associated with the high tree densities in these rangeland sites as was expressed by the high ETTE ha À1 (Abule et al, 2007).…”

“…The main reason for the increase in grass production at Degage and Kolbayu could be due to the relatively better basal cover value, low tree density and low grazing intensity in these rangelands (Abule et al, 2007). The decrease in grass production at Samayu and Mogassa, when compared to the other sites, could be associated with the high tree densities in these rangeland sites as was expressed by the high ETTE ha À1 (Abule et al, 2007).…”

Composition and Seasonality of Diet in Wild Hamadryas Baboons: Preliminary Findings from Filoha

“…Its unusual multilevel social system and male-dominated social organization are commonly thought to be evolutionary adaptations to the semi-desert environment in which it likely evolved, either in the Horn of Africa eral habitat types but is predominantly a semi-desert scrubland dominated by shrubby Acacia and Grewia [Swedell, 2002b;Abule et al, 2007] broadly similar to the habitat of hamadryas baboons in other parts of their geographic range [Sigg and Stolba, 1981;Biquand et al, 1992]. Other habitat types within the range of the Filoha population include grasslands and swamps dominated by Sporobolus and Cyperus grasses and small forests of doum palm trees (H. thebaica) .…”

Reviving a Traditional Pasture Management System in Fentale, East Central Ethiopia

“…A. nubica is the dominant bush species in the more flat, overgrazed areas, especially around permanent and semi-permanent villages. In the last few decades, the thorn bush vegetations have been expanding into the grassland (Abule et al 2007b). …”
