Centres of Plant Diversity (CPD) was established in 1998 as a joint classification initiative between the World Wildlife Fund (WWF) and the International Union for Conservation of Nature intended to identify the areas in the world that are of the highest conservation value in terms of protecting the highest number of plant species.

A Vavilov Center (of Diversity) is a region of the world first indicated by Nikolai Vavilov to be an original center for the domestication of plants. [3] For crop plants, Nikolai Vavilov identified differing numbers of centers: three in 1924, five in 1926, six in 1929, seven in 1931, eight in 1935 and reduced to seven again in 1940.
Later expeditions went to Sudan and Ethiopia, where he identified a center of diversity in 1926. [8] Vavilov created the world's first seed bank in the Institute of Plant Industry, Leningrad. [9] In 1927, Vavilov presented his theory of centers of origin to the public at the Fifth International Congress of Genetics in Berlin. [12]

A Centre of Endemism is an area in which the ranges of restricted-range species overlap, [1] or a localised area which has a high occurrence of endemics. [2] Centres of endemism may overlap with biodiversity hotspots which are biogeographic regions characterized both by high levels of plant endemism and by serious levels of habitat loss.
Harry Harlan was a friend of the famous Russian plant breeding expert Nikolai Vavilov, and at the age of fifteen Jack Harlan met Vavilov when the latter stayed at the Harlan house during an international conference. This meeting inspired Jack to become a plant collector himself, and plans were made for him to travel to Russia after finishing ...
A Palmer oak in Jurupa Valley is estimated to be 13,000 to 18,000 years old. The plant, which looks like a sprawling, dark green shrub, is now at the center of a development battle.
The Berlin-Dahlem location was already the site of a plant science center in the early 1900s. Research aims is to investigate the evolution and function of plant diversity and to design strategies for a prospective sustainable use of natural plant resources.
