Ecological Importance of the Silk Cotton Tree

• Protection to rock bees: Protects rock bee nests from predators like sloth bears with its spikes.
• Food : Tribal communities consume its reddish roots as food during the monsoon.
  • Food for larvae of moth: Leaves are food for larvae of a moth species called Bucculatrix crateracma.
• Significance of seed: Seeds are used by golden-crowned sparrows for nest lining with white cotton from its seeds.
• Provides Shelter: Nectar in flowers attracts various species like Dysdercus bugs, Indian crested porcupines, and Hanuman langurs.
• One-tree wildlife sanctuary: Since, this tree supports various  wildlife species including rock bees, the golden-crowned sparrow, and Hanuman langurs, It acts as a “one-tree wildlife sanctuary,”. 

Cultural  Significance

• Garasia tribe: The members of these tribes believe that they are descended from semal trees.
  • This tree provides these tribes opportunities for agroforestry and resources like food, fodder, and fuelwood.
• Kathodi tribe: This tribe  crafts musical instruments from its wood.
• Bhil tribe: This tribe makes utensils using semal trees. 

Conservation Challenges 

• Tree cutting for Holika Dahan celebrations: Every year, about 1,500-2,000 semal trees or branches are cut for Holika Dahan celebrations in Udaipur, despite legal protections.
  • The once-abundant crimson flowers of the semal tree are now rarely seen, indicating a decline in its population due to excessive cutting.
• Economic Opportunity for Tribal Members
  • Tribal communities rely on small agricultural plots, livestock, and manual labor for income.
    • They gather and sell minor forest products like bamboo, Pongamia pinnata seeds, and mahua flowers.
  • There are some Tribal members involved in cutting semal trees. They view it as an economic opportunity because harvesting wild trees requires less effort and cost compared to cultivating crops.
    • High Urban Demand: There is a high demand for semal trees, particularly from urban areas hosting large Holika Dahan events.
      • Disappearance of tree: This has led to the disappearance of semal trees from the forests of south Rajasthan.
• Lack of Formal Documentation: There has been little formal documentation or research on the topic since a study conducted in 2009.

Efforts for Conservation

• Semal Tree Conservation Mission’: In 2008, this mission was initiated under the Society for Microvita Research and Integrated Medicine.
• • The mission involves a diverse group of professionals raising awareness about the importance of semal trees.
    • They also advocate for using an iron pole instead of semal trees for Holi bonfires.
