Risk (46 as Least Concern and 13 as Near Threatened) when subject to the IUCN Red List
criteria. With the aim of evaluating the risk of extinction and of providing management tools
for natural habitats in these species, the distribution, size and structure of its population have
been measured according to IUCN criteria. Thus, their natural habitats are under threat of animal
grazing, road and dam constructions. Conservation management options are discussed.
