Bura’a area is famous for being the refuge for the hamadryas baboon and the Yemeni monitor lizard. The rugged and steep mountain chain hosts the largest area of relics of subtropical forest in the Arabian Peninsula. The foothills are populated by banana and the highlands by coffee and durum wheat. The biosphere is a safe haven for the Mimusops laurifolia, Stereospermum kunthianum and Antiaris toxicaria, the striped hyena, the white-tailed mongoose and the African lynx. The deep gorges preserve irrigation canals and tombs from the Bronze Age, engravings from the 4th century and old buildings from the Sulaihid dynasty in the 11th century. These inscriptions reveal the presence of the oldest monotheistic text discovered in Yemen.
