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?

Certain indigenous communities in India have deep- rooted traditions linked to ecology and agriculture. The Gond and Korku tribes, predominantly in Central India, have festivals such as 'Hari Jyoti' (Green Light) or 'Hariali' celebrated during the monsoon season which involve tree plantation, particularly focusing on fruit-bearing and useful trees, reflecting their close connection with the environment and agricultural cycles. This practice aligns with the description of a month-long, ecologically important festival centered around planting saplings of fruit- bearing trees.
