Description: <DIV STYLE="text-align:Left;"><DIV><DIV>Sand Sheets and Dunes with Distinct Shrub or Dwarf Shrub CoverStatus: Critical Habitat within Abu Dhabi emirate.Location: Generally in the northern, eastern, southern and central parts of the Emirate. Haloxylon persicum is confined to an area between Madinat Zayed and Wathba.Description: Areas of undulating sandy desert with dunes less than 20 metres in elevation, and with significant cover of dwarf shrubs (i.e. woody perennials less than 1 m high, usually less than 50 cm). Dwarf shrub species are Zygophyllum qatarense, Haloxylon salicornicum and Siedlitzia rosmarinus. Other species likely to be present are Cyperus conglomeratus, Dipterygium glaucum, Moltkiosis ciliata, Eremobium aegyptiacum, Silene villosa and Limeum arabicum. Breeding birds include Crested Lark, Greater Hoopoe-lark and Southern Grey Shrike. Shrub species (woody perennials more than 1m high) are Leptadenia pyrotechnica, Calotropis procera, Calligonum comosum and Haloxylon Persicum These areas are important for the native Haloxylon salicornicum (locally known as Rimth) and Haloxylon Persicum (locally known as Ghada). Stands of the shrub Haloxylon Persicum (‘ghada’) occupy a geographically distinct and well-delineated area south of Abu Dhabi City, where they form a characteristic species-poor plant assemblage (Haloxylon persicum-community) on low dunes. Frequent fogs in the region facilitate the growth of lichens on the bark of H. persicum. The fine branches of the shrubs comb out droplets of water from the atmosphere, a feature that has led Aspinall & Hellyer (2004) to describe this vegetation as a ‘dew forest’. The stands of Haloxylon persicum are of outstanding conservation value because this is the only natural occurrence in the UAE and in eastern Arabia in general. || مناطق من الصحراء الرملية المتموجة تحتوي على كثبان أقل من 20 مترًا في الارتفاع، مع غطاء كبير من الشجيرات القزمية (أي النباتات الخشبية المعمرة التي يقل ارتفاعها عن 1 متر، وعادةً ما تكون أقل من 50 سم).الأنواع النباتية من الشجيرات القزمية تشمل:Zygophyllum qatarenseHaloxylon salicornicumSiedlitzia rosmarinusأنواع أخرى قد تكون موجودة:Cyperus conglomeratusDipterygium glaucumMoltkiosis ciliataEremobium aegyptiacumSilene villosaLimeum arabicumالطيور المتكاثرة تشمل:القبرة المتوجة (Crested Lark)القبرة المتوجة الكبيرة (Greater Hoopoe-lark)الصرد الرمادي الجنوبي (Southern Grey Shrike)أنواع الشجيرات (النباتات الخشبية المعمرة التي يزيد ارتفاعها عن 1 متر):Leptadenia pyrotechnicaCalotropis proceraCalligonum comosumHaloxylon persicumتعد هذه المناطق مهمة لنباتي Haloxylon salicornicum (المعروف محليًا باسم الرمث) وHaloxylon persicum (المعروف محليًا باسم الغضا).توجد تجمعات من نبات الغضا (Haloxylon persicum) في منطقة جغرافية مميزة جنوب مدينة أبوظبي، حيث تشكل تجمعًا نباتيًا فقيرًا بالأنواع (مجتمع Haloxylon persicum) على الكثبان الرملية المنخفضة. تساعد الضباب المتكرر في المنطقة على نمو الأشنيات على لحاء نبات الغضا. تعمل الفروع الدقيقة للنبات على استخراج قطرات الماء من الجو، وهي ميزة دفعت أسبينال وهيلير (2004) لوصف هذه النباتات بـ"غابة الندى".تتميز تجمعات الغضا بقيمة كبيرة للحفاظ عليها لأنها تشكل الوجود الطبيعي الوحيد لهذا النوع في الإمارات العربية المتحدة وفي شرق شبه الجزيرة العربية بشكل عام.</DIV></DIV></DIV>
