Abstract: Phenological observations have a long tradition in the Czech Republic; the first phenological notes were taken in the 18th century. Within the entire phenological observation network of the Czech Hydrometeorological Institute, 45 plant species can be observed. These include perennial herbs, grass, and ground bushes growing wildly. Some observed species are among the group of so-called allergens, e.g. silver birch (Betula pendula Roth), cocksfoot (Dactylis glomerata L.), and meadow foxtail (Alopecurus pratensis L.). In this paper, we evaluated the phenological phase beginning of flowering for two of the aforementioned plants at the Mlýny, Chřibská research site (50°52’N, 14°29’E, 350 m a.s.l.). The aim was to assess which meteorological parameters influence phenological onsets as well as to analyze shifts in phenophase onset dates and temperature trends during 1959–2014. During this period, for B. pendula the average date of beginning of flowering was 28 April with a standard deviation of 10 days and for A. pratensis it was 20 May with a standard deviation of 8 days. The studied species are allergens and their timing and phenological shifting during the spring and their relationship with climate parameters may provide important information for forecasts as part of a pollen warning service.
