• Survey Area: Covered nearly 40 transects across various habitats including:
  • Primary evergreen forests
  • Semi-evergreen forests
  • Moist deciduous forests
  • Riparian corridors
  • Plantation landscapes
• Total Bird Species Documented: 198, raising the cumulative count in the Vazhachal Forest Division to 225 species.

• Continued sightings of seasonal migrants such as Forest Wagtail and Indian Blue Robin during an extended time frame suggest potential impacts of climate change.

Role of Indigenous Communities:

• The Kadars, local indigenous community, played a crucial role in guiding survey teams through difficult terrains, showcasing the importance of traditional ecological knowledge in conservation efforts.

Conservation Implications:

• Divisional Forest Officer Suresh Babu emphasized the necessity of periodic scientific surveys for understanding ecosystem dynamics and informing conservation strategies.
• The collected data will establish a scientific baseline for future conservation efforts focusing on habitat management and monitoring.

Future Directions:

• Plans to conduct annual monitoring programs integrating records of rare species and hornbill nesting data to enhance the effectiveness of habitat management initiatives.

Environmental Significance:

• The survey underscores the Vazhachal Forest Division's status as a biodiversity hotspot and highlights the health of its ecosystems through the presence of various endemic and migratory bird species.

This strategic setup of ongoing evaluation and collaboration with local communities will contribute to maintaining the ecological integrity of the forest region.
