Occurrence patterns of L. pulmonaria and its host trees (aspen and goat willow), together with 400-year fire history data, Teerisuo-Lososuo, Finland

All data have been previously used also in other studies (Gu et al. 2001, Snäll et al. 2005, Lankia et al. 2012, Ronnås et al. 2017). The data include two-time-point occurrence pattern data of an endangered lichen L. pulmonaria, empirical snapshot data on aspen (P. tremula) and goat willow (S. caprea) counts, and 400-year data of forest fires.

All data have been collected in the Teerisuo-Lososuo nature reserve, Kuhmo, Finland (2 086 ha; 63°88'N, 29°18'E) and projected in the Finnish YKJ projection. Ilkka Hanski initiated the surveys in the late 1990’s and Gergely Várkonyi, Matti Komulainen, Jari Huotari, Pirjo Appelgren and Mikko Heikura assisted with field work. The data include two-time-point occurrence pattern data of an endangered lichen L. pulmonaria, empirical snapshot data on aspen (P. tremula) and goat willow (S. caprea) counts, and 400-year data of forest fires.
