Many species that are not endangered today will likely be threatened in the future because of the growing population, the rising need for industrial and urban development and agricultural practices, the increasing threats of invasive species, and the effects of climate change. Therefore, actions aiming to maintain viable populations for all threatened or non-threatened species should be based on in-situ conservation of the species. These action plans should be classified as species management, action, conservation, or rescue plans depending on the degree of intervention required. For the future species management plans, in this study, the species belonging to the Fabaceae family (Lathyrus, Astragalus, Vicia, Lotus, Thermopsis), which are in the International Union for Conservation of Nature (IUCN) Red List and under threat of extinction in Turkey, has been reviewed based on the details about (1) their biogeographic regions, (2) habitats, (3) ecological characteristics, (4) potential threats, (5) economic importance, (6) ethnobotanical features and (7) usage opportunities among the people. Additionally, this study evaluates up-to-date records of the species' locations. As a result of the evaluations, the most critical threats to the natural habitats of the species belonging to the Fabaceae family are climate change, overgrazing, land reclamation, haymaking and erosion, deterioration caused by dam construction, and urbanization. Agriculture and anthropogenic habitat loss and degradation are also important threats. According to this study, it is vital to take the necessary conservation measures and develop conservation awareness for the future. Additionally, it is essential to determine these species' usage areas and determine their ecological and economic importance. The preparation of action plans for the conservation of species and the development of sustainable conservation and usage strategies, including genetic diversity, depend on the investigation of these species in all aspects.
