Awareness of the ecological characteristics and habitat needs of Tecomella undulata (Roxb.) Seem as a rare، valuable and multipurpose plant is of utmost importance in utilizing its diverse functions، especially at the local scale. For this purpose، due to the massive structure of habitats of this important species in Iran، the largest habitat in the world، which is located in the Dalfard region of Jiroft، was considered for this study. First، the habitat area was marked with a GPS device based on field operations and considered as an information layer in 2020. Then، topographic factors including altitude، slope and geographical directions were extracted in Arc-GIS 10.4.1 software. Variables as rainfall indices، freezing days، temperature indices including average temperature، maximum temperature، minimum temperature، absolute maximum temperature and absolute minimum temperature were examined based on the nearest meteorological station including Miandeh station. Geological characteristics were investigated based on lithological units. The circular plots of 1000 square meters (based on the canopy size of tree species) with 5 numbers were sampled to evaluate the components of canopy cover and associated species. The results showed that this valuable species can grow in the altitude range between 1289 to 1404 meters، slope range from 0 to 26% and all geographical directions. Existence of granite lithological units in the upstream and severe fluctuations of habitat environmental factors including high dry period، highly variable annual rainfall range of 39.5 to 578، presence of freezing days، temperature range of -4 to 49 °C are the unique habitat characteristics of this species.
