FIRST LEAF DATE  

Definition

  • The first leaf date can be generally defined as the average date when the first leaves appear on an indicator plant species. Conceptually, the first leaf date is indicative of the transition from winter to spring,typically when shrubs start to become active but before deciduous trees put on leaves. The first leaf date is subject to both large-scale climatic conditions and the phenological responses of the plant species under consideration. (en)
