A wildlife corridor, also known as a habitat corridor or green corridor, is a stretch of natural habitat that connects different populations of wildlife that have been separated by human activities like roads, buildings, or logging. These corridors allow animals to move between populations, which helps prevent problems like inbreeding and low genetic diversity, which can happen when animal groups are isolated.

Corridors also make it easier for populations to recover after events like fires or disease outbreaks by allowing individuals to migrate and establish new groups. Let us learn more!

7 Important Wildlife Corridors in India

Kaziranga-Karbi Anglong Corridor

  • The Kaziranga-Karbi Anglong Corridor spans 25,000 square kilometres across Assam, Meghalaya, and Nagaland. It’s a crucial wildlife corridor in India, particularly for large mammals like tigers, elephants, and rhinos. This corridor connects Kaziranga National Park and the Karbi Anglong hills, allowing animals to move between habitats. However, development and the presence of National Highway 37 pose threats to wildlife, especially during floods. Protecting this corridor from human activities is essential for preserving habitat and ensuring the survival of many species.

Terai Arc Landscape, Lower Himalayan Region

  • The Terai Arc Landscape extends 810 kilometers across Uttarakhand, Uttar Pradesh, Bihar in India, and Nepal’s low-lying hills. It serves as a vital migration corridor in the Lower Himalayan Region, covering 14 protected areas. This diverse landscape includes grasslands, forests, and river valleys, providing essential habitats for various species, including rare Indian rhinos, Asian elephants, and Bengal Tigers. The corridor offers space for species to migrate between parks and preserves, like Chitwan National Park in Nepal and Rajaji National Park in India, which alone cannot support a healthy population of large mammals. Protecting this corridor is crucial for the survival of many species.

The Kanha-Pench Corridor, Satpuda-Maikal Landscape

  • This corridor connects the Kanha and Pench Tiger Reserves and sustains a significant meta-population of tigers in central India. It’s home to around 120 tigers and various other important species. While human-wildlife conflict is not the primary threat, development projects like roads and railways could disrupt habitats.

The Sawantwadi-Dodamarg Wildlife Corridor

  • This corridor in southwestern India connects protected areas and is crucial for wildlife movement in the Western Ghats. It’s home to rare species like Bengal tigers, bears, and elephants. Concerns about mining in the area led to its designation as an ecologically sensitive zone.

Sanjay Gandhi National Park Wildlife Overpass

  • Under construction, this wildlife corridor in Mumbai’s Sanjay Gandhi National Park will be India’s first wildlife overpass. It aims to facilitate the movement of wildlife, including leopards and various bird species, between the park and the Tungareshwar Wildlife Sanctuary.

Rajaji-Corbett Corridor, Uttarakhand

  • Connecting two major protected areas, this corridor supports a diverse population of tigers, elephants, and leopards. However, it has suffered from forest loss and degradation due to human activities, hindering animal movement.

Ranthambhore-Kuno-Madhav Corridor, Western India

  • This corridor connects three protected tiger habitats and provides essential migration space for large mammals like tigers, chital, and sambar. Human encroachment poses a threat to the corridor’s integrity, particularly through land-use changes and agricultural expansion.

Types of Wildlife Corridors

Habitat corridors vary in width, with wider corridors generally attracting more wildlife. However, the effectiveness of a corridor depends more on its design than its width. Here are three categories based on corridor width:

  1. Regional Corridors: These are wider, typically over 500 meters, and connect major ecological features like migratory routes.
  2. Sub-regional Corridors: These are narrower than regional corridors, usually over 300 meters wide, and connect larger landscape features such as ridges and valleys.
  3. Local Corridors: These are narrower still, often less than 50 meters wide, and connect smaller habitat patches like gullies or wetlands.

Corridors can also be classified based on their continuity. Continuous corridors are unbroken strips of habitat, while “stepping stone” corridors are smaller patches of suitable habitat. However, stepping-stone corridors may be more vulnerable to edge effects.

Additionally, wildlife crossings like underpasses or overpasses are forms of corridors used to help animals cross man-made barriers like roads, reducing conflicts such as roadkill. Underpasses tend to be more successful than overpasses because animals are often hesitant to cross bridges in front of traffic.

Pros and Cons of Wildlife Corridors

Here are the pros and cons of wildlife corridors:


  1. Habitat Connectivity: Wildlife corridors facilitate the movement of animals between fragmented habitats, allowing them to access essential resources such as food, water, and mates. This helps maintain genetic diversity and population viability.
  2. Biodiversity Conservation: By providing safe passages for wildlife, corridors support the dispersal of species and contribute to the conservation of biodiversity. They enable the migration of both large and small animals, including endangered species.
  3. Reduced Human-Wildlife Conflict: Wildlife corridors can help reduce conflicts between humans and wildlife by directing animal movements away from human settlements. This can mitigate damage to crops, property, and infrastructure, and reduce the likelihood of human-wildlife encounters.
  4. Ecosystem Functioning: Corridors promote ecosystem functioning by facilitating the movement of seeds, pollen, and nutrients between different habitats. This enhances ecological processes such as pollination, seed dispersal, and natural regeneration.
  5. Tourism and Education: Well-designed wildlife corridors can provide opportunities for ecotourism, nature-based recreation, and environmental education. They offer visitors the chance to observe wildlife in their natural habitats and learn about conservation efforts.


  1. Habitat Fragmentation: Despite their intended purpose, poorly planned corridors can exacerbate habitat fragmentation by creating barriers to wildlife movement or directing animals into high-risk areas such as roads or human settlements.
  2. Invasive Species Spread: Wildlife corridors may inadvertently facilitate the spread of invasive species by providing pathways for their dispersal into new habitats. This can have negative impacts on native species and ecosystem dynamics.
  3. Predation and Disease Transmission: Corridors can increase the risk of predation and disease transmission, especially if they funnel animals into concentrated areas where predators or disease vectors are present.
  4. Human Disturbance: Corridors that pass through human-dominated landscapes may face disturbances such as habitat destruction, pollution, poaching, and disturbance from human activities. These disturbances can compromise the effectiveness of the corridor and pose threats to wildlife.
  5. Maintenance and Management: Establishing and maintaining wildlife corridors require ongoing efforts, including land acquisition, habitat restoration, fencing, monitoring, and enforcement of regulations. These activities can be resource-intensive and may face logistical and financial challenges.

Wildlife Corridors in India – Purpose

Habitat corridors are an important tool in managing areas where natural habitats have been disrupted due to human development or natural disasters. When land is fragmented, animal populations can become unstable. Corridors help reconnect these fragmented areas and stabilize populations by aiding in three key factors:

  1. Colonization: Animals can move to new areas to find resources like food or shelter when their core habitat is lacking.
  2. Migration: Species that move seasonally can do so more easily when they can navigate around human-made barriers.
  3. Interbreeding: Animals can find mates in nearby regions, increasing genetic diversity.

Early researchers like Daniel Rosenberg et al. defined wildlife corridors as pathways that facilitate movement without being limited by specific vegetation or habitat types.

Corridors not only benefit animal populations but also indirectly affect plant populations by helping spread pollen and seeds. They need to be large enough to support viable populations, minimize migration barriers, and maximize connections between populations.

These corridors can include aquatic habitats like rivers and streams, often referred to as riparian ribbons. On land, they can be wooded strips or urban hedges that connect different habitat areas.

Wildlife Corridors in India – Users

  • Many species fall into one of two categories: passage users and corridor dwellers.
  • Passage users are animals that use corridors temporarily, such as for seasonal migration, moving young animals away from their birthplace, or traveling within a large territory. Examples include large herbivores, medium to large carnivores, and migratory species.
  • Corridor dwellers, on the other hand, can spend longer periods in corridors, ranging from several days to several years. These species include plants, reptiles, amphibians, birds, insects, and small mammals. For corridor dwellers, the corridor must offer enough resources to support their entire life cycle.
