Globally common,locally rare: revisiting disregarded genetic diversity for conservation planning of widespread species

Species endangerment, as determined by the national and international authorities, are crucial in conservation decisions at local and regional scales. While species are the priority unit of conservation, the subspecies of widespread species are often neglected in conservation planning and research, irrespective of their unique genetic identity. Peripheral populations of widespread species are often isolated and endangered while their status on the IUCN Red List is considered as ‘Least Concern’. We advocate for the evaluation of widespread polytypic species, and to recognize the importance of assessing intraspecific populations that are distinct from the distribution of widespread species.
