The exercise also aided in identifying which of the multipurpose plants is most under pressure in the area and to identify the factors which are the threats of medicinal plants. The participants in this exercise were selected based on their long years of experience as traditional herbal medicine practitioners [19] in the districts. For the exercise of direct matrix ranking, a focus group discussion (FGD) was conducted to know the preference based on multipurpose criteria on the plants.
