نبذة
يقع في شمال غرب المحيط الهندي، بالقرب من خليج عدن، ويمتد على مساحة 250 كلم. يشمل أربع جزر وجزيرتين صخريتين صغيرتين يبدو وكأنها امتداد للقرن الأفريقي. إنه موقع استثنائي من حيث التنوع الكبير في نباتاته ونسبة الأنواع المستوطنة: ذلك أن 73% من أنواع النباتات (من أصل 528 نوعاً) و09% من أنواع الزواحف و59% من أنواع الحلزونيات البرية المتواجدة فيه غير موجودة في أي مناطق أخرى من العالم. أما بالنسبة للعصافير، فالموقع يؤوي أنواعاً هامة على المستوى العالمي (291 نوعاً، يتوالد 44 منها في الجزر، فيما يهاجر 58 منها بانتظام)، ومن بينها بعض الأنواع المهددة بالانقراض. وتتميز الحياة البحرية في سقطرى بتنوع كبير، مع تواجد 352 نوعاً من المرجان الباني للشعب، و730 نوعاً من الأسماك الساحلية، و300 نوع من السراطين والكركند والإربيان.

Values Socotra is globally important for biodiversity conservation because of its exceptionally rich and distinct flora and fauna. 37% of Socotra’s plant species, 90% of its reptile species and 95% of its land snail species do not occur anywhere else in the world. Socotra is of particular importance to the Horn of Africa’s biodiversity hotspot and, as one of the most biodiversity rich and distinct islands in the world, has been termed the “Galápagos of the Indian Ocean”. Criterion (x): Biological diversity and threatened species: Socotra is globally important for biodiversity conservation because of its exceptional level of biodiversity and endemism in many terrestrial and marine groups of organisms. Socotra is particularly important for its diversity of plants and has 825 plant species of which 307 (37%) are endemic. Socotra has high importance for bird species as underlined by the identification by Birdlife International of 22 Important Bird Areas on Socotra. Socotra also supports globally significant populations of other land and sea birds, including a number of threatened species. Extremely high levels of endemism occur in Socotra’s reptiles (34 species, 90% endemism) and land snails (96 species, 95% endemism). The marine life of Socotra is also very diverse, with 253 species of reef-building corals, 730 species of coastal fish and 300 species of crab, lobster and shrimp, and well represented in the property’s marine areas. Integrity The property is of sufficient size to adequately represent all the terrestrial and marine features and processes that are essential for the long term conservation of the archipelago’s rich and distinct biodiversity. The terrestrial nature sanctuaries, national parks and areas of special botanical interest included in the property encompass about 75% of the total land area. They protect all the major vegetation types, areas of high floral and faunal values, and important bird areas. The marine nature sanctuaries included in the property encompass the most important elements of marine biodiversity. The property’s integrity is further enhanced by terrestrial and marine buffer zones that are not part of the inscribed property. Requirements for Protection and Management All component areas of the property have legal protection; however there is a need to strengthen the legislative framework, and management and enforcement capacity. Whilst the property’s terrestrial and marine habitats are generally still in good condition, management planning needs to deal more effectively with current threats including roading, overgrazing and overharvesting of terrestrial and marine natural resources. Potential future threats include unsustainable tourism and invasive species. Impacts of these threats on Socotra’s biodiversity need to be closely monitored and minimized. A sustainable financing strategy is required to ensure the necessary human and financial resources for the long term management of the property. Appropriate linkages need to be developed between the management of the property, its buffer zones and the Socotra Biosphere Reserve.
