Seasonal and annual dynamics of western Canadian boreal forest plant communities: a legacy dataset spanning four decades

The primary purpose of the Seasonal Dynamics (SEADYN) and later Annual Dynamics (ANNDYN) research projects was to document seasonal changes in the vegetative composition during the snow-free season (May through October) and longer-term changes in vegetation and forest mensuration for boreal forest stands in Alberta, Canada dominated by Pinus banksiana (Lamb.). Two regions were used for this study: one in the Hondo-Slave Lake (hereafter, Hondo) region of Alberta, which was surveyed from 1980 to 2015, and a second location in the Athabasca Oil Sands (hereafter, AOS) region in northeastern Alberta, which was surveyed from 1981 to 1984 and thought to have substantial atmospheric pollution due to regional industrial development (oil sands mining and processing). Extensive metadata related to these data, including experimental methods, can be found in the document 'metadata.pdf'.

季节动态（SEADYN）及后续年度动态（ANNDYN）研究项目的核心目标，是记录加拿大阿尔伯塔省以北美短叶松（Pinus banksiana (Lamb.)）为优势种的北方林分，在无雪期（5月至10月）内的植被组成季节变化，以及植被与森林测树学指标的长期变化趋势。本研究设置两个调查区域：其一为阿尔伯塔省的Hondo-Slave Lake区域（下文简称Hondo区域），调查时段为1980年至2015年；其二为阿尔伯塔省东北部的阿萨巴斯卡油砂区域（下文简称AOS区域），调查时段为1981年至1984年，该区域因区域工业开发（油砂开采与加工）被认为存在显著大气污染。与本数据集相关的详细元数据（含实验方法）可查阅文档"metadata.pdf"。
