Appendix2. Introduced species recorded in the High Arctic archipelago Svalbard. Abbreviations of site names: LYR = Longyearbyen, NÅ = Ny-Ålesund, PYR = Pyramiden, BAR = Barentsburg. Site names are given with their modern equivalent and spelling according to (e.g. Moskushamn = Hiorthhamn, LongyearCity = Longyearbyen). “Tempelfjorden: Nøis’ hut” (Hadač 1941) is currently Fredheim. Phenological stages (PS) are V = vegetative, B = with flower buds, Fl = in flower (anthesis), and Fr = with fruits. Temp1 and Temp2 are, respectively, deviations from the mean July temperature in the year of observation and in the year prior to observation. nd = no data available. In the years 1977 and 1979, Tishkov (1985) found 12-15 species but did not report their names, and they are thus not included here. Species recorded by (Roalsø (2012) are only included if they differ from our own observations from recent years. Likewise, species recorded by Tishkov (Elven and Elvebakk 1996)are only included if they differ from those of (Liška and Soldán (2004). Species in bold are on the black list of Svalbard (Gederaas et al. 2012). * = reported for the first time on Svalbard.
