Pterocarpus marsupium Roxb., a significant deciduous tree species of high medicinal value is depleting fast due to various biotic and abiotic factors included in the near threatened category IUCN red list. The potential distribution range P. for India was modeled year 2020 2050 under different Representative Concentration Pathways (RCP 2.6, 4.5, 6.0 8.5) scenarios climate change using Maxent, study impact on its distribution. revealed that at present ~3.08% geographical area highly suitable depending upon RCP this may expand upto ~ 3.11-3.53% by 2050. zone wise analysis climatic conditions predicted prominent presence habitat central comprising 1.82% total followed southern western zones with 0.53% 0.49% respectively. northward shifting an increase ~0.6-11%, ~6.4-24.5% ~20-60% central, respectively, but ~26%-53% decrease eastern zone. Annual precipitation (Bio_12) most contributor variable limiting as well future conditions. result provides baseline information identification prioritization areas conservation promotion India.
