We conducted a detailed investigation of 2,884 plots in northeastern China and selected 6 nationally protected orchid species (the number of plots for each species >=5) to plan PPAs in order to conserve these endangered plants. First, we estimated the potential habitat distributions of 6 orchid species using species distribution models (in the program Maxent). Second, we identified PPAs using the results of both Maxent and systematic conservation planning software (Zonation). We found that the PPAs we identified were all distributed in the eastern, northeastern, and northern parts of the study region on which we focused. We observed that existing nature reserves in those areas were much smaller than the PPAs we identified, suggesting the need for expansion of these zones. Finally, we identified some recommended protection areas based on our PPAs, which we believe are suitable areas of in situ conservation. These areas could assist in the formulation of protection policies for these endangered orchid species. Our results have broad implications for conservation biology and the redefinition of protective zones for at-risk species. 收起<<
