“…The forest covers about 76% of the land area. According to the classification of Grierson and Long (1983), three types of forests can be distinguished: (i) sub-tropical forests (up to 1000 m), (ii) warm, broadleaved forests (1000-2000 m), and (iii) cool, broad-leaved forests (2000 m and above). The dominant species recorded within the watershed are given in Appendix 1.…”

We assessed the impact of anthropogenic activities such as selective felling and resource extraction on plant diversity and forest structure in the broad-leaved forests of Bhutan. The forest area was grouped into three zones according to human influence: settlement-agriculture, semi-disturbed, and natural forest. A total of 140 plant species were identified. Maximum species richness of trees (8 species/plot) was recorded in natural forests and least in the settlement-agriculture zone (3 species/plot). Shannon (1.73 ± 0.62) and Simpson diversity (5.49 ± 2.97) indices were highest for the natural forest zone as compared to the semidisturbed (0.92 ± 0.74, 2.70 ± 2.05) and settlement-agriculture zones (0.74 ± 0.74, 2.24 ± 2.13). The density and basal area of trees decreased from 373 N ha −1 and 37.9 m 2 ha −1 in the natural forest zone to 114 N ha −1 and 5.7 m 2 ha −1 in the settlement-agriculture zone. The diameter distribution revealed a lack of commercial tree species in the higher dbh classes from the settlement-agriculture and semi-disturbed zones due to selective felling. Increasing accessibility and anthropogenic activities caused the reduction in biodiversity of the watershed. Selective felling and resource extraction created gaps which were colonized by non-timber species and this may change the forest structure.

“…Traditional healers of different tribal communities were approached for the present study. Plants were collected from different sampling sites and identified with the help of available flora [6][7] . Data were obtained through interviews using both structures and semi structures questionnaires, group discussion and reviewing published and unpublished documents.…”

Aritar is hilly area and altitude of the area varies from 800-3000 meter. The region harbor different tribal communities like Lepcha, Bhutia, Sherpa, Limboo, Newar, Chettri, Bhaun, Rai, Tamang, Sunwar, and Gurung. Due to the diversity of different tribal communities, traditional healers of different groups are found in this area. Medicinal importances of different plants were recorded after conducting interview with traditional healers, old man, women of different tribal communities of the area. The traditional medicinal uses of 50 plants species belonging to 38 families are reported in my study.

“…The species flourishes in elevation ranges of 1,000-2,800 m in North America, 1,600-3,800 m in China and present in alpine and subalpine zones in Russia (Shishkin 1936;Shilong & Rabeler 2001;Morton 2005). This species was not reported from the western Himalaya (Pakistan, Jammu & Kashmir, Himachal Pradesh, Uttarakhand), central Himalaya (Nepal) and the eastern Himalaya (Sikkim, Bhutan, Arunachal Pradesh) (Ghazanfar & Nasir 1974;Chowdhery & Wadhwa 1984;Grierson 1984;Majumdar 1993;Hajra et al 1996;Srivastava 1998;Press et al 2000;Majumdar 2002;Uniyal et al 2007). Taxonomically, S. umbellata belongs to the section Eustellaria Fenzl and series Umbellatae Schischk.…”

The species Stellaria umbellata is reported as a new record for the western Himalayan flora. Critical examination of the species in nature, Indian herbaria, online herbaria and protologue confirmed its identity as Stellaria umbellata. Earlier, it was erroneously identified in the western Himalaya as Stellaria subumbellata or Holosteum umbellatum. This species was previously not reported from the western, central or eastern Himalaya and thus, it is also a new record for the flora of the Himalaya.
