A brief history of conservation at the Royal Botanic Gardens, Kew

Summary

When Princess Augusta and Lord Bute, followed by Sir Joseph Banks and King George III, started gathering plants at Kew, conservation on the site can be said to have begun. Although the primary motive then was to assist the expansion of the British Empire and trade, rare plants were gathered and some became rare or extinct in the wild as their habitats were destroyed. The primary motive in the nineteenth century was not conservation, but the history of conservation at the Royal Gardens at Kew dates back to its very origins. Subsequent regimes at Kew maintained and added to the collections thereby adding to their conservation value. Many early collections are of species now listed within the IUCN categories of endangerment. Environmental awareness and concern had begun by the time that Professor Jack Heslop-Harrison became director and he was the first director actively to initiate specific conservation programmes such as seed banking and work on red data books. From then on conservation became an integral part of the work programme of Kew and the focus on conservation has increased with each subsequent director. This eventually led to the transformation of the embryonic seed banking activities into the Millennium Seed Bank, the largest and most important bank in the world for the conservation of the seeds of wild species. It currently holds just over ten percent of all seed plant species. Conservation at Kew over the past three decades has very much been a balance between ex situ work and in situ activities to help conservation in the overseas areas where Kew scientists have experience. Throughout the history of the gardens there has been a vital interest in economic botany that has developed from moving plants around the empire to much work on the sustainable use of plants and ecosystems thereby better equipping the institution to subsequently work on in situ conservation. Significant conservation activity at Kew has been possible because it is being supported by a solid research programme that includes such areas as systematics and molecular genetics and laboratories, a large herbarium and a large library. Kew has played an important role in stimulating conservation work elsewhere and such units as the Threatened Plants Unit of IUCN and Botanic Gardens Conservation International (BGCI) have their roots in Kew. Among other important conservation initiatives have been the creation of a unit to work with the implementation of the CITES treaty on the trade of endangered plants and a legal unit to work on issues of the Convention on Biological Diversity (CBD). There is no doubt that the Royal Botanic Gardens at Kew is at the forefront of plant conservation.
