Cavity-nesting birds are considered an indicator of bird diversity in these forest ecosystem. To help conservation of avian diversity in Hyrcanian forests, we applied ensemble of three species distribution models (Generalised Boosted Models, Maximum Entropy modeling, Random Forest) and predicted the impacts of climate change on distribution of Dendrocopos major an important tree-cavity nesting bird in the area. We also estimated protected areas coverage for suitable habitat of the species in Hyrcanian forests. Results showed that area of suitable habitat of the species is and this will increase to 30805 by 2070 and 34392 by 2100. We also found that 15 percent of the species suitable habitat covered by protected areas. Hyrcanian forests are rich in the sense of biological diversity.
