Abstract

 

An extensive sampling was conducted for medicinal orchids in the state of Uttarakhand between the years 2003 to 2005 covering an altitudinal range of 600 – 3600 m. Transects of 1 km length were laid randomly in various habitat types depending upon the geographical coverage of the habitats.  Six medicinal orchid species belonging to four genera were recorded in different habitats. Dactylorhiza hatagirea and Habenaria intermedia are highly endangered in the state. A total of seven habitat types were identified where medicinal orchids were found. Among seven habitats Banj-oak habitat was found the most suitable habitat for the orchids followed by Mixed-oak and Banj Grassy Slopes.

 

Key words: Uttarakhand, medicinal orchids, habitat, Banj-oak, Dactylorhiza hatagirea, Habenaria intermedia.
