Phenology of M. asper at different altitudinal ranges, based on citizen science data. The box-plots represent the distribution of dates, expressed as “days of the year”. The medians for the altitudinal ranges are: 143 (23 May) (0–400 m a.s.l.); 156 (05 June) (401–800 m a.s.l.); 173 (22 June) (801–1,200 m a.s.l.); 178 (27 June) (1,201–1,600 m a.s.l.).
