Orchidaceae is well known as ornamental plant since long back, but it has a great contribution in the field of medicine as well. Diversity is considered as the natural home for all creatures viz. animate, inanimate, flora, fauna etc. of a region. Ultapani range has a great potential for exploration of orchid. Ultapani forest range consists of an area of about 224.64 Sq. Km. and is located in between N26⁰52′13.5″ to N26⁰39′18.1″ and E90⁰20′37.1″ to E90⁰21′28.0″. According to the survey of 2004 there are 24 species within 16 genus and according to the survey of 2014 there are 9 species within 8 genus. But in the present study it was found that the number of orchid in Ultapani range is reducing drastically day by day. Now Ultapani is left with 9 species within 5 genus. The orchids which are found in the region of Ultapani Forest Range have a long standing medicinal value. The paper will explore the data of species identified till date and its diversity in Ultapani forest range and also some of the vital challenges such as reduction, poaching, deforestation, habitat destruction etc. of present times.
