Survival and growth of 711 forest tree taxa in eight French arboretums from three different climate regions

Abstract The dataset is checklist of 711 native and exotic forest tree taxa (species, subspecies and arieties) from 177 genera worldwide, their survival and growth in eight French arboretums from three contrasted bioclimates. Planted between 1969 and 1976, 338 taxa have survived and occur as at least one individual in one plot. Purpose A series of eight arboretums was installed some 50 years ago for testing the ability of a wide range of mostly exotic tree species to survive in marginal, stressful habitats (high elevation, low fertility, atmospheric pollution, drought). Surviving and well-growing species were expected to be used to enrich the local tree community or replace local species suffering from die-back. The well-documented, georeferenced survival and growth data from these arboretums we present here, will contribute to the renewed scientific interest arboretums represent for understanding how trees adapt to climate change and to providing adaptive solutions to forest management.

摘要 本数据集收录了全球177个属的711种本土与外来林木类群（物种、亚种及变种）的清单，记录了这些类群在法国8个隶属于不同生物气候区的树木园中的存活与生长情况。这批林木于1969年至1976年间栽植，其中338个类群成功存活，且至少在一个样地中存在至少一株个体。
研究初衷：约50年前，科研团队搭建了由8个树木园组成的试验平台，用以测试绝大多数外来树种在边缘胁迫生境（高海拔、低肥力、大气污染、干旱环境）中的存活能力。当时预期，存活且长势良好的树种可用于丰富当地林木群落，或替代出现枯梢现象的本土树种。
本次发布的这批经过详实记录、附带地理坐标的树木园存活与生长数据，将推动学界重新关注树木园在解析树木适应气候变化机制、为森林管理提供适应性解决方案方面的科学价值。
