The highest peak in southwestern Darfur, Jebel Marra stands at a whopping 10,000 feet
. Not only is the mountain great for such activities as hiking and mountain climbing, but the area is stunning as well, boasting such natural formations as waterfalls and volcanic lakes.
While the region is currently experiencing political instability, the mountain should be bookmarked as it is a great find in a land that is so geographically flat.
Jebel Marra volcanic field covers a broad area of the Marra Mountains and contains early basaltic lava flows overlain by thick sequences of pyroclastic-flow deposits.
The northern part of the volcanic field displays trachytic lava plugs and spines forming residual inselbergs and young basaltic scoria cones and lava flows. Ash eruptions at Deriba caldera may have continued into early historical time (Burton and Wickers, 1966), and fumarolic activity has been observed on the flanks of a small pyroclastic cone within the caldera.
It consists of a range of mountains 240- km long and 80 km. wide, with waterfalls, volcanic lakes in an outstanding scenic beauty.
The climate of the mountain is mild and of Mediterranean nature, where it rains almost the whole year round and that allows for the growth of abundant vegetation of citrus, apples and clusters of dense forest trees.
Jebel Marra’s heavy rainfall and numerous gorges supply vast arable lands with a continuous flow of water turning it into ideal soil for the cultivation of sorghum, millet, vegetables and a wide variety of orchard trees.
Woody Plant Communities ;
According to a study there are evidences that most, if not all, of the woody vegetation communities in Jebel Marra have been derived from some more complex types by continuous disturbance since antiquity.
Here past and contemporary land use types are described and associated to woody plants distribution. Empirical stratified sampling methods of plant geographers and ecologists are applied to both natural and artificial systems. Frequencies, densities and diversities for all woody plant communities are estimated by standard ecological indices. It was found that throughout known history woody plant communities were subjected to different degrees of suppression.
Thus, the present distribution of the woody plant communities reflects the different stages as well as modes of suppression. Drastic population movements and the resulting changes in land use types since antiquity, seem to be the chief explanation behind the variations in modes of suppression
