Every year, a monthlong ecologically important campaign/festival is held during which certain communities/tribes plant saplings of fruit-bearing trees. Which of the following are such communities/tribes?

Mentions Van Mahotsav as a year‑long community celebration to promote awareness about the value of trees and conservation—an example of an annual tree‑planting festival.

A student could check whether Van Mahotsav (or similar month‑long campaigns) is observed in Sikkim and whether local communities (Bhutia/Lepcha) participate by planting fruit trees.

Defines community forestry/social forestry as tree planting undertaken by local communities with community responsibility for protection.

Use this rule to infer that if Bhutia/Lepcha engage in community forestry in Sikkim, they plausibly may plant saplings (including fruit trees) during organised campaigns.

Recommends promoting eco‑cultural landscapes (gives Demazong Buddhist landscape, Sikkim as example) and participatory plantation for rehabilitation—linking local culture to tree planting.

A student could investigate whether Demazong/other Sikkim eco‑cultural initiatives include month‑long plantings involving Bhutia/Lepcha and whether fruit trees are emphasised.

Describes Lepcha‑community‑run ecotourism and local community management near Khangchendzonga, indicating organised community environmental activity in Lepcha areas.

One could look into activities of such community committees to see if they run annual ecological campaigns that include planting saplings (possibly fruit trees).

Gives an example (Bhil community) of a community tradition of coming together to plant thousands of trees as a duty toward the environment, showing precedent for communal ecological planting.

Apply this pattern to Himalayan/tribal communities: check whether Bhutia/Lepcha have analogous local traditions or festivals during which they plant saplings, especially fruit‑bearing ones.
