🐆 NOT A THREAT, BUT A NEIGHBOUR 🐾
With increasing leopard sightings around the University of Peradeniya, it’s easy to see these magnificent animals as a danger. But they aren’t invading our space, they’re surviving in an ecosystem that we increasingly share with them.
Join us,
🗓️ on 2nd September (Wednesday)
⏰ at 12.15 p.m.
📍 at Zoology New Lecture Theatre
to understand them instead of fearing them, and to respect & protect their habitats and movement corridors so both wildlife and people can coexist safely. 🐆🧡
Because sometimes, what we call a threat is simply a neighbour trying to find its way home.

🌿 Geo spatial Mapping of Ecological Niches Along Stream Corridors in the University of Peradeniya 🌿

Biodiversity conservation begins at the local level. Our study explored the ecological importance of stream corridors within the University of Peradeniya using GIS and Remote Sensing technologies.

Through spatial analysis, vegetation classification, hydro-logical mapping, and ecological niche assessment, we identified riparian zones associated with natural and mixed forests as highly significant biodiversity-supporting habitats. These stream corridors function as ecological connectors that support habitat continuity, species movement, nutrient cycling, and ecosystem resilience.

🔍 Key Findings:
✅ Stream corridors maintain ecological connectivity within fragmented landscapes
✅ Riparian vegetation supports rich ecological niches and micro-habitats
✅ Natural and mixed forest areas show high ecological potential
✅ GIS and Remote Sensing provide effective tools for local biodiversity conservation planning

This study highlights how local landscapes such as university environments can contribute meaningfully to global biodiversity conservation goals.

🌱 Protecting ecological corridors today strengthens ecosystem resilience for future generations.

📌Rising Peafowl Populations in Sri Lanka: Ecological Success or Emerging Conflict?

In recent years, the visible increase of Indian peafowl (Pavo cristatus) across Sri Lanka has sparked debate among conservationists, farmers, and local communities. Once primarily associated with dry zone forests and protected landscapes such as Yala National Park, peafowl are now frequently observed in agricultural lands, village settlements, and peri-urban areas.

While some interpret this expansion as a sign of ecological resilience, others experience it as an emerging environmental and socio-economic challenge.

📌Agricultural and Community Impacts

Several studies in Sri Lanka have documented crop damage attributed to peafowl, particularly in paddy, vegetables, legumes, and fruit cultivations. Farmers report economic losses and challenges in protecting crops due to the species’ protected status.

Public discourse further reflects these tensions, with residents reporting noise disturbances, garden damage, and frequent peafowl encounters in residential areas. These observations highlight that the challenge extends beyond biodiversity management, affecting rural livelihoods and the broader issue of human wildlife coexistence.

Is the increasing presence of peafowl a threat? Should it be controlled?

📌Cultural Significance and Policy Complexity

The management challenge is further complicated by cultural and religious reverence. In Hindu tradition, the peafowl is associated with Lord Murugan, whose sacred site at Kataragama remains a significant spiritual center. Within Buddhist symbolism, the peafowl represents wisdom and transformation.

As a legally protected species under the authority of the Department of Wildlife Conservation, lethal control measures generate ethical and social resistance.

This creates a complex conservation dilemma: how can Sri Lanka balance biodiversity protection, cultural respect, and agricultural sustainability?

Thus, the increasing presence of peafowl should not be viewed solely as a pest. Why is it happening?
Changing Landscapes and Expanding Ranges

The Indian peafowl is native to Sri Lanka and has long held ecological and cultural significance. However, recent ecological observations indicate a shift in distribution patterns beyond traditional dry zone habitats. Several interrelated factors contribute to this expansion:

Decline of natural predators such as leopards and jackals
Habitat fragmentation and deforestation
Agricultural intensification providing new food sources
Legal protection under national wildlife regulations

When predator populations decline and landscapes are modified by infrastructure development, settlement expansion, and wetland degradation, ecological checks and balances weaken. In such contexts, adaptable species with high reproductive potential may experience rapid population growth.

What is to be done?

📌Towards Integrated Environmental Management

Short-term measures such as localized removal may provide temporary relief but fail to address underlying ecological drivers. Sustainable management requires:

Restoration of predator habitats
Scientific population monitoring
Community-based conflict mitigation
Adaptive policy frameworks
Strengthened Environmental Education

The peafowl population increase reflects broader processes of land use change, environmental degradation, and shifting ecological relationships. Effective solutions must therefore be systemic rather than reactive.

Effective wildlife management must integrate scientific evidence, cultural sensitivity, and community participation. The growing peafowl population should be viewed not just as a pest or a conservation success, but as a reflection of ecological balance and sustainable development. Safeguarding Sri Lanka’s biodiversity one of the nation’s most valuable assets requires research-based, inclusive strategies that support both ecosystems and human livelihoods, promoting coexistence and environmental stewardship.

🍃Environmental Awareness Programme CES - University of Peradeniya 🍂

The Centre of Environmental Sustainability (CES) successfully conducted an Environmental Awareness Programme for undergraduate students of the Faculty of Dental Sciences, University of Peradeniya, on 23rd January 2026, with the participation of 57 students.

The programme aimed to enhance awareness of pressing environmental challenges such as climate change, pollution, biodiversity loss, and resource depletion, while encouraging personal responsibility and sustainable practices.

Students engaged in interactive discussions, group poster activities, zero-waste and waste-to-wealth concepts, and a guided nature walk - reinforcing the message that individual actions collectively create meaningful environmental impact.
