Reclaiming Assam’s elephant habitat, one weed at a time, Pg9

Key Highlights:

• A project in Assam is working to restore elephant habitats by managing Invasive Alien Plants (IAPs).
• The initiative is focused on Khalingduar Reserve Forest in the Dhansiri Forest Division of Udalguri district, within the Bodoland Territorial Region (BTR).
• Aaranyak, a Guwahati-based conservation organization, is implementing the project with support from the International Elephant Foundation.
• The project targets specific IAP species like Lantana camara, Chromolaena odorata, and Mikania micrantha.
• A key strategy involves converting cleared IAP biomass into biochar to improve soil health and sequester carbon.

Detailed Insights:

• IAPs significantly reduce food options for herbivores, including elephants, by outcompeting native vegetation for resources.
• India faces a widespread challenge from IAPs, with studies indicating their rapid expansion across natural areas, impacting biodiversity and livelihoods.
• The project's approach includes manual uprooting of IAPs and seed-ball-assisted regeneration to promote native plant recovery.
• Biochar, produced by heating organic waste in a low-oxygen environment, acts as a stable carbon form that resists decay for thousands of years.
• It enhances soil properties like water retention, nutrient retention, aggregation, and microbial habitat, turning a botanical liability into a carbon-rich asset.
• The Bodoland Territorial Region (BTR) is an autonomous division in Assam, established for self-governance and development of the Bodo people, and is rich in ecological wealth.
• Elephant conservation in India is also addressed by the Project Elephant, a Centrally Sponsored Scheme launched in 1992 by the Ministry of Environment, Forest and Climate Change to protect elephants, their habitats, and corridors.

Key Concepts Involved:

• Invasive Alien Plants (IAPs): Non-native plant species that spread aggressively, outcompeting native flora and disrupting ecosystems.
• Biochar: A charcoal-like substance made by heating organic waste in a controlled environment, used for soil amendment and carbon sequestration.
• Carbon Sequestration: The process of capturing and long-term storage of atmospheric carbon dioxide to mitigate climate change.
• Project Elephant: A Centrally Sponsored Scheme launched in 1992 by the Government of India for the protection of elephants, their habitats, and corridors.
