在过去的二十年里，由于人类活动，印度尼西亚已经失去了30%的面积。为了克服这个问题，红树林恢复——通常被解释为红树林种植计划——成为最受欢迎的选择。这些努力可以增强数量功能（增加红树林面积和树木种植数量），但质量功能（生物多样性和生态功能）仍不清楚。该分析与中高分辨率卫星图像分析同时进行，以区分这些站点的红树林冠层格局。结果表明：恢复区红树林的beta多样性值低于自然区，在卫星影像上表现为冠层更均匀、纹理更细；主要通过单一栽培进行的恢复工作无法产生与自然红树林相同的红树林生态系统功能。通过比较自然红树林（北苏拉威西）和恢复红树林（西巴厘）两个研究点的beta多样性差异，探讨恢复工作是否能发展出与自然红树林生态系统同等的生态功能。
Indonesia has lost 30% of the area over the past two decades due to anthropogenic activities. To overcome this problem, mangrove rehabilitation-which is generally interpreted as mangrove planting program - become the most popular option. These efforts could enhance the quantitative function (increasing mangrove areas extent and number of trees planted), yet the quality functions (biodiversity and ecological function) remain unclear. This analysis was carried out simultaneously with medium to high-resolution satellite image analysis to differentiate mangrove canopy pattern of these sites. The results showed that beta diversity value of mangroves in rehabilitation sites was lower than mangroves in natural area, which was characterized in satellite imagery as more uniform canopy and finer texture. Rehabilitation efforts that are mostly done through monoculture, are unable to produce an equal mangrove ecosystem function as natural mangroves do. This paper aims to examine the effectiveness of rehabilitation efforts whether they can develop an equal ecological function as good as natural mangrove ecosystem, by comparing the difference of beta diversity in two study sites which representing the natural (north Sulawesi) and rehabilitated mangrove (West Bali).
