Cal Madow (also Al Madow, Al Medu, Calmadow or Al Mado) (Somali: Buuraha Calmadow, Arabic: علمدو) is a mountain range in northeastern Somalia, extending from several kilometers west of Bosaso to northwest of Erigavo. Its peak sits at almost 2500 m in Shimbiris, northwest of Erigavo. Cal Madow was a tourist destination in the late 1980s. The local population of the Sanaag region is primarily responsible for preserving the habitat, which continues to face the risk of deforestation.
The dense mountain forest sits at an altitude of between 700–800 m above sea level, and has a mean annual rainfall of 750–850 mm. In addition to rainfall, Cal Madow receives additional precipitation in the form of fog and winter rains, which sustain isolated forests of juniperus, buxus etc. Mist also appears to be important in the distribution of juniperus (dayib), one of the species locals use for timber. For timber production, the buxus (dhoqos), buxus and celtis (boodaar) poles are cut from living trees in the evergreen forest. The discovery of the locust bean (ceratonia), lavenders and many other plant species has emphasized the many links the Cal Madow highlands have with the Mediterranean region. The Lamadaya waterfalls is one of the best scenery in Cal Madow.
Despite the current changes in land use, Cal Madow has internationally valuable unexploited mineral deposits and unique natural habitats. It is considered a key area for oil exploration, and has a petroleum system identical to and formerly contiguous with those within the Republic of Yemen. Florally, Cal Madow has approximately 1,000 plant species, 200 of which are only found this mountain range.
