| Abstract: |
This paper focuses on the ecological status and diversity indices: Simson’s Index (C),
Simson’s Index of Dominance (D) and Shannon-Weaver Index (H) of Dactylorhiza
hatagirea and its associates- Rheum australe and Rumex nepalensis in Lete village of
Mustang District within the Annapurna Conservation Area. The study was conducted
during the monsoon season (June/July) of 2013 in the Lete VDC of Mustang District.
The study site possessed an area of 4.5 ha. Altogether, 100 circular plots, each with
25 m2 area, were laid out purposively within the study area; the sampling intensity
being 5.55%. The relative frequency, the relative density, the abundance, the relative
coverage and the Important Value Index of the species were found to be 61.11, 53.91,
1,061.54, 72.2 and 187.24 respectively. Similarly, the Simson’s Index (C), the Simson’s
Index of Dominance (D) and the Shannon-Weaver Index of the species were found to
be 0.41, 0.59 and 3.27 respectively, indicating relatively even and relatively diverse
community. The study showed relatively higher values of all the parameters of D.
hatagirea as compared to its associates indicating good ecological value. However,
threats remain due to the illegal harvesting of this valuable orchid and overgrazing in
the study site. |
