The present study documents the conservation status and ecological characteristic of 22 trees belonging to 16 families. Among these 12 species were found to be rare, vulnerable (6 species), Infrequent (2 species), endangered (one specie) and dominant (2 species) in Tehsil Karak, Pakistan. The conservation status of plants is determined according to IUCN 2001, Red Data List Categories and Criteria. After two years extensive field studies on the basis of questioner including availability of plant, collection of plant, growth of plant, plant parts, population size, geographic range and habitat we have concluded that Salvadora oleoides Decne. is endangered (EN) specie in Tehsil Karak.
