The argan tree (Argania spinosa) is a native species of the sub-Saharan region of Morocco, in the southwest of the country, which grows in arid and semiarid areas.

The United Nations designated 12 May the International Day of Plant Health (IDPH) to raise global awareness on how protecting plant health can help end hunger, reduce poverty, protect biodiversity and the environment, and boost economic development.

European Natura 2000 Day relates to the 21st May 1992, when both EU Habitats Directive and LIFE programme were approved.
