Island ecosystems are particularly important to biodiversity around as they host a large number of floral communities. Socotra Island contains a number of endemic flora and fauna, which is of great ecological importance. This study investigated the spatiotemporal changes in geomorphological characteristics, shoreline, and vegetation in Socotra Island using satellite imagery between 1988 and 2019. Our results indicated that the shoreline of Socotra Island did not undergo any significant changes and the observed erosion-accretion processes were nearly balanced. High elevation areas are restricted to the surrounding areas of central massif, where endemic woody vegetation is mainly found. There has been an increase in the area covered by grassland and shrub vegetation during the study period, possibly caused by grazing and invasive species.

岛屿生态系统中的生物多样性和自然保护：索科特拉群岛（也门）的时空变化

岛屿生态系统对周围的生物多样性特别重要，因为它们拥有大量的花卉群落。索科特拉岛（Socotra Island）拥有许多特有的动植物，具有重要的生态意义。本研究利用卫星图像调查了1988年至2019年索科特拉岛的地貌特征，海岸线和植被的时空变化。我们的结果表明，索科特拉岛的海岸线没有发生任何显着变化，观察到的侵蚀累积过程几乎平衡。高海拔地区仅限于中央地块的周边地区，那里主要发现特有的木本植物。在研究期间，草地和灌木植被覆盖的面积有所增加，这可能是由于放牧和入侵物种引起的。
