Site description Dessa’a forest is on the eastern escarpment, north-east of Mekele and c.20 km south-east of Agula town, Eastern Zone. The topography in Dessa’a is varied and includes some flatter areas and gentle slopes as well as steep scarps. The forest extends in an easterly direction along and down the escarpment, and forms a climatic buffer zone between the cool highlands of Tigray and the hot lowlands in Afar Region. Generally, rainfall along this part of the escarpment is marginal for tree growth. However, it seems likely that the forest abstracts moisture from the clouds that build up along the escarpment. Close to the forest there is a valley where one of the oldest irrigation systems in the country still functions. The soils in the valley are deep and fertile with both grassy and somewhat swampy patches as well as cultivated fields. Most of the trees in the forest are found at the higher altitudes, and relatively undisturbed forest exists only on the steep eastern slopes. A detailed study of the vegetation has not been made, but the species composition is most likely similar to that of the escarpment forests in Eritrea. The dominant tree species is Juniperus procera, with some patches of Olea europaea cuspidata; at lower altitudes Juniperus procera tends to be replaced by Acacia spp. including A. origena, a species only found on the eastern escarpment of Ethiopia and Eritrea, and in Yemen. A range of small understorey trees and bushes are likely to occur. Particularly characteristic of such dry montane forests are Barbeya oleoides (a monotypic family), Cadia purpurea, Berberis holstii and Tarchonanthus camphoratus. The plateau above the escarpment is heavily cultivated and the forest provides valuable grazing, particularly in the dry season. A major feature of the forest is the centuries-old track that passes through it, used by camel trains bringing blocks of salt up from the Afar.
