Umkaddada locality is located within 12th and 15th degree of latitude N and the 25th and 28th of longitude E, among the semi-arid zone. It coversine area of some 40,000 km2. Umkaddada locality, like all other areas of Darfur was influenced by war and tribal conflicts which led to migration of many people, some of them being internally displaced people (IDPs) while others fled to neighboring countries. Droughts and shortage of rainfall hit the area continuously since the1970ies. The war and displacement led to crowding of people in certain areas. The increased demand for food, fuel and building materials led to adoption of many practices that were environmentally destructive among which was intensive cutting of trees, over grazing and expansion of farming areas at the expense of rangeland. This situation led to some changes in vegetation cover and range plants species composition. When vegetation species composition changes the most affected plants are those that are preferred by animals in the area. Also animals can change their plant preferences in order to cope with the vegetation changes resulting from human activities. Goats are the animal type kept over all Umkaddada Locality because it is the animal of poorer people. This paper attempts to assess plant preference by goats at seed set stage in protected and open range sites using the bite count technique. It was found that the plants most preferred in open rangeland were Echinocloa colonum, Ipomoea vagan, Train them aportulacastrum and Alycicarpus glumaceus respectively. The frequencies of these species in the range were 25.6%, 18.0%, 16.0 4.0% and 30.0% respectively. While the most preferred species in protected rangeland were Echinocloa colonum, Dactylactenium aegyptium, Zalya pentandra and Monsonia senegalensis. Echinocloa colonum.
