Abstract The Indo-Malaysian region harbours some of the highest diversity globally, yet it is also has the highest rates of deforestation. Furthermore some countries have shown up-to a 10 times increase in the area deforested annually between 2001 and 2014. Large-scale forest clearance is preceded by the growth of road networks which provide a stark warning for the region's future as many of the roads established for clearance or infrastructure are illegal and unmapped. In some regions almost 100% of roads were previously unmapped on the global roads map, yet 99.9% of deforestation occurs within 2.5 km of these roads. In Borneo the majority of plantations are on an industrial-scale averaging over 10 km2 in size, whereas most of the region typically has plantations under 1 km2 integrated into a landscape mosaic, though the preliminary infrastructure for industrial plantations are being developed in parts of the region. Within the coming decade most of the region may lose almost all unprotected forests. As some countries have only 2% of their land-area protected this condemns many of the regions endemic species to extinction. Urgent measures are needed to protect a much larger proportion of remaining forest, as this offers the only means to protect many of the regions endemic species.

印马森林已经走到尽头了吗?

摘要 印度-马来西亚地区拥有全球最高的多样性,但也是森林砍伐率最高的地区。此外,一些国家的森林砍伐面积在 2001 年至 2014 年间每年增加多达 10 倍。大规模森林砍伐之前是道路网络的增长,这为该地区的未来提供了严峻的警告,因为许多道路已建成清除或基础设施是非法和未映射的。在某些地区,几乎 100% 的道路以前都未在全球道路地图上绘制,但 99.9% 的森林砍伐发生在这些道路的 2.5 公里范围内。在婆罗洲,大多数种植园都具有工业规模,平均面积超过 10 平方公里,而该地区的大部分地区通常都将 1 平方公里以下的种植园整合到景观马赛克中,尽管该地区部分地区正在开发工业种植园的初步基础设施。在未来十年内,该地区的大部分地区可能会失去几乎所有未受保护的森林。由于一些国家只有 2% 的土地受到保护,这导致该地区的许多特有物种灭绝。需要采取紧急措施来保护更大比例的剩余森林,因为这是保护许多地区特有物种的唯一手段。
