Delhi's New Forest Strategy: Reconnecting Fragmented Green Spaces for Wildlife
New Delhi has unveiled a comprehensive decade-long working plan for its forests, with a primary focus on reconnecting fragmented green spaces through innovative solutions like overhead forests and underpasses. This ambitious initiative aims to support wildlife movement and enhance survival prospects in the capital's urban landscape.
The Primary Challenge: Habitat Fragmentation
The plan identifies habitat fragmentation as the most significant threat to Delhi's wildlife, surpassing traditional concerns like poaching or hunting. Expanding human settlements and infrastructure development have created isolated forest patches that severely limit space, reduce natural food availability, and disrupt animal movement patterns.
"There is not much threat to the wildlife from organised poaching and hunting," the working plan states. "However, habitat fragmentation and the small size of forest patches result in lack of space, which causes paucity of fodder and impedes free movement of wildlife."
This fragmentation forces animals like porcupines, rhesus macaques, and snakes to venture into human habitations, increasing human-wildlife conflicts.
Innovative Connectivity Solutions
The forest department proposes two main approaches to address this fragmentation:
- Hanging Forests: Where urban establishments prevent direct forest linking, the plan suggests creating overhead bridges "replete with trees, undergrowth and bushes" to allow animals to move freely between separated patches.
- Underpasses and Tunnels: Waterholes can be connected to adjoining forest patches through underground passages, enabling safe animal access without endangering themselves or nearby human settlements.
Rescue Data Reveals Urban Wildlife Challenges
Between 2022 and 2024, forest authorities rescued 1,560 animals, with rhesus macaques being the most frequently rescued species. "The macaques were mostly involved in accidents, including road hits, falls from height and electrocution," the report notes.
Alarmingly, a significant portion of rescue attempts ended with animals "not found" at reported locations, highlighting gaps in response coordination and emphasizing the need for faster, more efficient rescue systems.
Other rescued animals included sambar deer, nilgai, porcupines, hares, and even a striped hyena, demonstrating the diversity of wildlife struggling in Delhi's fragmented habitats.
Systematic Reforestation with Fruit-Bearing Species
The decade-long plan proposes systematic planting of fruit-bearing trees to provide adequate natural food sources for wildlife. At least 45 species have been identified, including:
- Mango
- Litchi
- Star fruit
- Java plum
- Jamun
- Falsa
- Coffee plum
While previous suggestions called for planting 5,000 fruit-bearing trees annually in north and central forest divisions, the new plan proposes more ambitious targets: 8,000 trees yearly in the west forest division and 10,000 in the south forest division.
Protection of Key Species and Conflict Resolution
The working plan emphasizes protection for several key species, including leopards, sambar deer, chital, Indian flying foxes, Asiatic jackals, and nilgai. It calls for establishing dedicated rescue centers with trained personnel and developing comprehensive strategies to address human-wildlife conflicts that inevitably arise in urban environments.
This holistic approach represents Delhi's most significant effort to balance urban development with wildlife conservation, recognizing that reconnecting fragmented habitats is essential for maintaining biodiversity in one of the world's most densely populated metropolitan areas.
