What criteria we should follow to identify conservation priority species i.e. globally threatened status or flagship species?
This is a nice research article related to your area of interest. Here is the link https://doi.org/10.1007/s40415-015-0197-z
I believe if the species is endemic and it is coming under the RET categories according to IUCN then those species can be taken as priority species... Even this can be used for non endemic species as well... May be reading of AICHI TARGET will help you out in this as well.....
- Climate change is driving shifts in the distribution of plants and animals, and prioritizing management actions for such shifts is a necessary but technically difficult challenge.
- We worked with state agencies in the southeastern United States to identify high-priority amphibian species, to model the vulnerabilities of those species to regional climate change, and to identify long-term climatic refugia within the context of existing conservation lands.
- Directly interfacing with state natural resource experts ensured that 1) species prioritization schemes extend beyond political boundaries and 2) our models resulted in conservation-relevant applications. We used a correlative model to project midcentury distributions of suitable climate for priority species and to evaluate each species’ vulnerability to climate change.
- Using spatially explicit projected climate distributions, we ranked existing protected areas relative to their ability to provide climatic refugia for priority species in 2050. We identified 21 species as regional high-priority species. Fifteen of the 21species are forecast to lose more than 85% of their climatically suitable habitat. Regions in the Appalachian Mountains ,the Florida Panhandle, and the north-central region of Alabama are projected to lose the most climatic habitat for priority amphibian species.
- We identified many existing protected areas as midcentury climatic refugia in the Appalachians; however, our projections indicated refugia in the Southeast Coastal Plain to be exceedingly scarce. Although the topographic relief present in the Appalachians appears to provide future conservation opportunities via climatic refugia, the Coastal Plain affords fewer such opportunities and conservation of amphibians in that region is likely to be more challenging.

In my counrty, the identification of conservation priority species should meet at least one of the following conditions:
1. Species with small populations and narrow distribution ranges.
2. Threatened species (VU, EN, CR) with important economic, scientific or cultural value.
3. Wild or genetically related species of important crops or livestocks.
4. Species that are economically important but whose population sizes have been drastically reduced by overuse.
A priority species is a threatened or an endangered species. These species are in danger of extinction throughout its habitat/range. According to IUCN, an endangered/priority species is one (1) whose population decrease is of 50-70% over 10 years, (2) a total geographic area less than 5000 sq km or local population area less than 500 sq km, (3) a population size less than 2500 adults, (4) a restricted population of 250 adults, and (5) a statistical prediction that the species will get extinct within the next 20 years. Hence, conservation priority species in a habitat can be identified through any one of the above criteria.
