Lepordae Lepus fagani Ethiopian Hare<br />

Hagos Yohannes, 2006 pers<strong>on</strong>al observati<strong>on</strong><br />

In the Buri Peninsula, there are about 66 bird species which include: Struthio camelus<br />

(Ostrich), Ardeotis arabs (Arabian bustard), Rhodoph<strong>on</strong>eus cruentus (Rosy-patched bush<br />

shrike), Merops orientalis (Little green bee eater), Anthreptes platarus metallicus (Pygmy<br />

sun bird), Trachyph<strong>on</strong>us margaritatus (Yellow-breasted), Pycn<strong>on</strong>otus barbatus, (Whitevented<br />

bulbul) etc. Most of these bird species are in a good c<strong>on</strong>diti<strong>on</strong> and are stable while<br />

some of them like the Arabian bustard are getting rare and require special c<strong>on</strong>servati<strong>on</strong><br />

attenti<strong>on</strong>.<br />

Threats<br />

The most serious bush land, grassland and wooded grassland habitats threats are:<br />

- Unc<strong>on</strong>trolled fire devastates a lot of woodland and grasslands,<br />

- Expansi<strong>on</strong> of villages and towns,<br />

- Expansi<strong>on</strong> of agriculture,<br />

- Recurrent droughts,<br />

- Invasive alien specie (Prosopis juliflora; Corvus splendens),<br />

- Illegal hunting of wildlife around Buri and Wengebo<br />

1.3.1.4 Barren Land/ Semi desert Ecosystem<br />

The barren land/semi desert ecosystem occurs in the eastern coastal plains and in some<br />

parts of the north western of Eritrea. The total area is estimated at about 47,301 km 2 ,<br />

(FAO, 1997).<br />

Status and Trend<br />

The climate in the semi desert area is so dry with very small and so erratic rainfall. Most<br />

of the land is bare and covered with sand duns. There is no recent comprehensive study<br />

c<strong>on</strong>ducted <strong>on</strong> the status of biological diversity in this particular ecosystem, but according<br />

to the biodiversity stocktaking assessment (DoE, 1999) there exist drought and salt<br />

tolerant grass species such as: Panicum turgidum, Cenchrus ciliaris Cenchrus ciliata,<br />

Leptothrium senegalens and Aristida sp., al<strong>on</strong>g with Euphorbia granulata. Tribulus<br />

l<strong>on</strong>gipetalus, Indigofera anabaptista, Indigofera spinosa, Pav<strong>on</strong>ia kotschyi, and Tephrosia<br />

sp.<br />

In the wadis, there are just a few Acacia tortilis subsp. raddiana, A. ehrenbergiana,<br />

A.nubica, Cadaba rotundifolia, Commiphora abyssinica, Tamarix aphylla), Ziziphus<br />

spina christi , Salvadora persica and Del<strong>on</strong>ix elata. The number of species, which are<br />

found in the northern part of the semi desert area of the coastal plans, clustered under<br />

different families is stated in Table-9.<br />
