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. Here we present a gap analysis indicator methodology that provides a pragmatic estimate of the comprehensiveness of conservation of the genetic diversity within useful wild plants, both ex situ and in situ. The methodology compares the geographic and ecological variation evident from analyses of the ‘site of collection’ of samples of plant taxa that are safeguarded in genebanks and other living plant repositories, as well as the variation evident in the proportion of species’ ranges inhabiting protected areas, against the full range of geographic and ecological variation in their native distri...
