Beginning approximately 10,000 years ago, the advent of agriculture led to strong selection on agricultural crops. Crop wild relatives, compatible with crops and persisting in natural populations, remain critical reservoirs of adaptive genetic variation for crop improvement. With habitat loss, landuse change, and a rapidly changing climate, many crop wild relatives are increasingly facing declining populations. In the northern Fertile Crescent, between the Tigris and Euphrates rivers, several crop wild relatives of important crops such as wheat, barley, rye, peas, lentils, fava beans, and chickpea can be found. We examine some of these taxa, their distributions and attributes, and conservation threats. Although many of these taxa have been collected and deposited into international genebanks, in situ preservation in protected natural populations is the greatest need for all of these taxa.
