Site information, seedling counts, and microclimate data for: \"Limited prospects for future alpine treeline advance in the Canadian Rocky Mountains\"

These data were produced as part of a study investigating the effects various biotic and abiotic properties on tree seedling germination beyond existing geographic ranges. Engelmann spruce seeds were grown in a seed addition experiment at four study areas in the Canadian Rocky Mountains.本数据集源自一项研究，该研究旨在探究各类生物（biotic）与非生物（abiotic）属性对现有地理分布范围之外区域内树木幼苗萌发的影响。研究以恩氏云杉（Engelmann spruce）种子为实验材料，在加拿大落基山脉的4个研究区域开展了种子添加实验。
