Data from Stark and Manninen: Plant δ15N signatures in historical reindeer corrals in boreal forests show long-term immobilization of animal-derived nitrogen in bryophytes and plant litter

This datafile consists the biomasses of the dominant understorey plant species and functional types as well as their δ15N signatures in 26 control forests and historical reindeer (Rangifer tarandus L.) corrals used in animal husbandry between late 1800s to early 1960s. The forest sites were assigned to two forest types that represent different levels of site productivity: mesic forests (high productivity; N = 8) and sub-xeric forests (low productivity, N = 18), in northern boreal forest zone in Finland.
