Changes in timing of spring events in days per decade for individual species grouped by taxonomy or functional type. Each bar represents a separate, independent species. Negative values indicate advancement (earlier changes through time) while positive values indicate delay (later changes through time). Far more spring events are coming earlier than are coming later.
