Using a quasi-experimental approach and spatial modelling, this project will test the influence of natural and anthropogenic factors on the success of natural forest restoration in an expansive landscape dominated by oil palm production (Northern Borneo). Southeast Asia has experienced some of the highest rates of land-use and land cover change globally, with 65% of the terrestrial land surface now covered by human-modified tropical forests .Unlike monoculture timber or oil palm plantations, logged forests often retain a large proportion of their endemic biodiversity and ecosystem functions. If managed appropriately, they hold tremendous potential for biodiversity conservation and carbon sequestration. This PhD project will resolve key uncertainties surrounding this appropriate management by identifying the biological, environmental and anthropogenic constraints on tree re-establishment in logged forest ecosystems. Using a combination of field-, desk-and greenhouse-based techniques, the PhD student will examine the role of human management (such as reduced impact logging, liana removal), biotic processes (dispersal, competition, herbivory, mycorrhizas) and abiotic factors(topography, microclimate, soil properties, landscape connectivity) in regulating tree establishment and growth in the Murum region in Sarawak, Malaysian Borneo. We expect the PhD student to use a blend of greenhouse studies, manipulative field experiments, remote sensing and advanced, 'big data' spatial modelling. Full training will be provided from world experts in these fields. Working with our CASE Partner, the PhD will be able to feed those findings into management plans detailing actions that pave the way for successful forest restoration activities in the future.

利用准实验方法和空间模型，该项目将测试自然和人为因素对以油棕榈油生产为主的广阔地貌(北婆罗洲)的天然林恢复成功的影响。东南亚经历了全球土地利用和土地覆盖变化率最高的地区之一，65%的陆地表面现在被人类改造的热带森林覆盖。与单一栽培木材或油棕榈林不同，伐木森林往往保留了很大比例的特有生物多样性和生态系统功能。如果管理得当，它们在生物多样性保护和碳封存方面具有巨大的潜力。这一博士项目将通过确定在伐木森林生态系统中重建树木的生物、环境和人为限制因素，解决围绕这种适当管理的关键不确定性。这位博士生将结合野外、办公桌和温室的技术，研究人类管理(如减少影响的伐木、藤本植物的移除)、生物过程(扩散、竞争、草食、菌根)和非生物因素(地形、小气候、土壤特性、景观连通性)在调节马来西亚婆罗洲沙捞越穆鲁姆地区树木建立和生长中的作用。我们希望这位博士生综合运用温室研究、操纵性田间实验、遥感和先进的“大数据”空间模型。这些领域的世界专家将提供全面培训。与我们的CASE合作伙伴合作，博士将能够将这些调查结果纳入管理计划，详细说明为未来成功的森林恢复活动铺平道路的行动。
