挪威云杉（Picea abies (L.) Karst.）是芬诺斯坎迪亚地区的主要北方树种，但其全新世历史的重要方面尚不清楚。现存的亚高山克隆群下方和瑞典斯坎德斯山脉无树沼泽中的亚化石木材碎片现在有力地证明了云杉早在公元 10 世纪就生长在这里。 8000 BP。这比根据花粉数据推断当地存在的时间早了 5000 多年。现在可以反驳反复出现的关于迁徙滞后的猜测，有利于全新世大部分时间里普遍存在的气候-植物平衡。经过冰川均衡陆地隆升调整后，树木界限于2017年后退了约120 m。
Norway spruce (Picea abies (L.) Karst.) is the dominant boreal tree in Fennoscandia, but important aspects of its Holocene history are unknown. Subfossil wood fragments underneath living subalpine clonal groups and in a tree-less mire in the Scandes Mountains of Sweden now firmly demonstrate that spruce grew here as early as c. 8000 BP. That is more than 5000 years before inferences of local presence have been made from pollen data. Recurrent speculation of migrational lags can now be refuted in favour of a climate-plant equilibrium prevailing throughout much of the Holocene. After adjustment for glacio-isostatic land-uplift, the tree-limit has retreated about 120 m in
