IUCN status of the species was determined based on occurrence of the species in natural habitats. Review of propagation and cultiva- tion An extensive survey of literature was carried out to determine the current status of propaga- tion and cultivation of Saussurea species in the IHR. For the review of literature, traditional libraries at a variety of different institutions, as well as various websites, were utilized.8,28-42 Results and Discussion Diversity, distribution and habitat preference only In the present study, 62 species of Saussurea were recorded from the IHR. All the species were herbaceous in nature and distributed between 550 m and 5,700 m. The greatest species diversity (33 spp.) was recorded in the use zone between 3,500 m and 5,000 m (Figure 2). This high species diversity may be due to var- ied soil, climate and geography of the zone, Figure 1. (A) Saussurea costus (photo: Dr. J.S. Butola); (B) Saussurea gossypiphora (photo: Dr. R.S.
