Here is a partial list of these organizations:

• Annamalai Reforestation Society
• Tamil Nadu Forest Department
• Forest Way
• Aruna Partnership (with Shantimalai Trust) – Girivalam Seva Project

These organizations are trying to prevent deforestation and promote sustainable ecological solutions through planting, education, and sometimes, fighting fires. They also collect garbage and maintain small parks along the Giripradakshina path.
