The generation length for Ursus thibetanus is 10 years. It is difficult to estimate the population of either bear species, even in surveyed areas. However, indices such as relative abundance from each survey site can provide some information on relative status. According to Forest Resource Assessment by FAO, during 1975-2010, Myanmar lost around 50% of its closed forest area which are the main habitat of the species. Overall, this suggests that population trends for this species are declining, with an inferred population reduction of more than 30% over the past three generations, a trend which is projected to occur at a similar rate into the future.
