Polygonum samsunicum is one of the endemic species from Turkey. Up to now, it has been only known from the type locality (Samsun /Ladik). This research intends to define the global conservation status and strategies of locally distributed endemic P. samsunicum which has been confronted with the danger of extinction due to anthropogenic effects in recent years. In this research, we did extensive field studies and collected all needed data for determining the precise conservation status of P. samsunicum. We reported nine additional populations from Upper Tersakan valley, where the Mediterranean climate is dominant, and the size of populations, altitude, coordinates, habitat types, and the threats it faces in each locality were given. GeoCAT analyses at global levels indicate the grade of occurrence 21.609 km2 and area of occupancy 10.094 km2 and there could be an inferred decline due to habitat loss and fragmentation of the original population, suggesting local endemic species might be classified as CR, based on criteria B1ab (i, ii, iii) + 2ab (i, ii, iii) in the Red List categorization.

For in-situ conservation, phenological life history and detailed ecological studies, as well as population monitoring and ex-situ conservation studies should be continued together. Establishing cooperation between universities, research institutes, and local management authorities is strongly needed for long-term monitoring of population size, distribution, overgrazing, and public awareness.
