Comprehensiveness of conservation of useful wild plants: An operational indicator for biodiversity and sustainable development targets
Plants are essential sources of food, medicine, shelter, fuel, feed, and forage, and provide a wide range of additional ecosystem and cultural services to humanity. In recognition of the tremendous value of useful plants and of the increasing threats to their persistence, international agreements including the Convention on Biological Diversity, the Sustainable Development Goals, and the International Treaty on Plant Genetic Resources for Food and Agriculture have created ambitious conservation targets which must be measured through quantitative indicators so as to facilitate the development and implementation of strategies aimed at safeguarding their genetic diversity. Gaps in the current list of functioning indicators for these targets suggest that the development of effective measurements of the state of conservation of the genetic diversity within useful plants is a major challenge.
