Community Forestry: Involves planting trees on public or community-owned lands such as village pastures, temple lands, roadsides, canal banks, railway lines, and schools.
Farm Forestry: Farmers grow trees on their own lands for both commercial and non-commercial purposes, contributing to sustainable land use and biodiversity conservation.
These initiatives aim to enhance forest cover, promote sustainable land management practices, and support local communities in benefiting from forest resources.

The effectiveness of government policies on forest and wildlife conservation heavily relies on the active participation of local communities. Here are some effective strategies:
Awareness and Education: Regular meetings and workshops with local communities are crucial for raising awareness about the benefits of conservation. Government officials can explain conservation policies and how local communities can contribute.
Incentives for Conservation: Providing incentives to individuals or communities who actively protect local trees and wildlife can be a powerful motivator. This could include rewards for sustainable practices, reporting illegal activities, or participating in conservation efforts.
NGO Support: Non-governmental organizations (NGOs) play a vital role in training and educating communities about conservation practices. They can provide technical expertise, training programs, and resources to help communities effectively conserve forests and wildlife.
