Historical attempts to establish mangrove, Avicennia marina in Kuwait resulted in the development of isolated communities along the northern Kuwait coastline. Mangrove establishment in Kuwait coastal waters have already demonstrated positive impacts in terms of enhancing biodiversity and increasing the habitat complexity. This study describes the establishment of a sustainable population of A. marina (Grey mangrove), a euryhaline and cold tolerant species on man-made islands of Sabah-Al Ahmad Sea City (SAASC), along the southern coast of Kuwait during 2006−2015. A total of 62,605 mangrove seeds were collected from the Abu Dhabi (United Arab Emirates) ecotype during 2006−2008. Overall germination rates in the nursery were 71.8 %, and seedlings were hardened through incremental stages of saline irrigation to become acclimatized to ambient salinity (42−43ppt). Seedlings were planted along the shoreline of the man-made islands of SAASC during May (2007–2009) and growth was monitored by measuring stem length (cm) on a monthly basis during 2009−2015. Plantation success increased initially from 8.3%–62%. The success of mangrove establishment was influenced by harsh arid and variable climatic conditions, and wave induced mortality. Effective mitigation measures through management actions and the provision of wind and wave protection ensured the successful establishment of a sustainable mangrove population in SAASC.

在科威特的人造岛屿上建立红树林生态系统:在充满挑战和变化的环境中的可持续成果

在科威特建立红树林,Avicennia码头的历史尝试导致科威特北部海岸线沿线偏远社区的发展。在科威特沿海水域建立红树林对提高生物多样性和增加生境复杂性已经产生了积极影响。这项研究描述了A. marina的可持续种群的建立(灰色红树林)是科威特南部沿海沙巴-艾哈迈德海城(SAASC)的人工岛上的一种耐盐碱和耐寒物种,在2006-2015年期间。在2006-2008年期间,从阿布扎比(阿拉伯联合酋长国)生态类型中总共采集了62,605种红树林种子。苗圃的总体发芽率为71.8%,幼苗通过逐步的盐水灌溉而硬化,以适应环境盐度(42-43ppt)。在5月(2007-2009年)沿SAASC人工岛的海岸线种植了幼苗,并通过在2009-2015年期间每月测量茎长(cm)来监测生长。人工林的成功率最初从8.3%–62%提高。建立红树林的成功受到干旱和多变的气候条件以及波浪诱发的死亡率的影响。
