Do snowdrops and hazel bloom earlier each year? With the BAYSICS app, “citizen scientists” can report the blooming of certain plants and thereby contribute to climate research. Now, at the beginning of spring, the researchers of BAYSICS subproject 4 are particularly interested in the blooming of snowdrops, hazel, coltsfoot, cornelian cherry, weeping birch, blackthorn and forsythia.
