Ecological Corridors

Ecological corridors represent critical conservation infrastructure that maintains ecosystem connectivity across fragmented landscapes. These pathways serve as lifelines for biodiversity, enabling species movement, genetic exchange, and ecosystem resilience.

Core Functions

Movement Facilitation

• Support of daily animal movements for resource access
• Enabling seasonal migration patterns
• Facilitating genetic diversity through population connectivity
• Climate change adaptation through species distribution shifts

Ecosystem Services

• Maintenance of ecological processes
• Enhancement of pollination networks
• Water flow regulation and soil conservation
• Carbon sequestration through vegetation preservation

Types of Corridors

1. Linear Corridors

   • Riparian zones along waterways
   • hedgerows and tree lines
   • Road verges with native vegetation
   • Power line clearings with managed vegetation

2. Landscape Corridors

   • Mountain ranges
   • River systems
   • Forest corridors
   • Coastal zones

3. Stepping Stones

   • Discrete habitat patches
   • Urban green spaces
   • Wildlife reserves
   • Agricultural buffer zones

Design Principles

Physical Characteristics

• Sufficient width to support target species
• Appropriate habitat quality and structure
• Habitat heterogeneity for diverse species needs

   • Agricultural land use demands

2. Social and Economic Factors

   • Land ownership and access rights
   • Resource allocation
   • Stakeholder engagement
   • Cost-benefit considerations

3. Management Issues

   • Invasive species control
   • Habitat maintenance
   • Human-wildlife conflict management
   • Long-term monitoring needs
