Protection of Sri Lanka’s Unique Nilgala Savanna: Largest Intact Ecosystem Now a Forest Reserve

At dawn on June 2, 2025, Sri Lanka took a landmark step in conservation history by officially designating the vast Nilgala landscape as a protected forest reserve. Spanning approximately 40,000 hectares (100,000 acres), this declaration marks Nilgala as the country’s largest intact savanna ecosystem. It combines diverse habitats—dry evergreen forests, grasslands, sacred sites, and granite hillocks—supporting extraordinary biodiversity and deep cultural significance rooted in the heritage of the Vedda indigenous people.

In this SEO-optimized deep dive, we explore Nilgala’s ecological richness, its cultural and spiritual importance, the story behind its protection, and the conservation challenges that lie ahead.

Biodiversity Highlights: A Mosaic of Unique Habitats

Nilgala’s landscape is a mosaic of:

  • Dry mixed evergreen forest sheltering species typically found in wetter zones or higher elevations.
  • Savanna grasslands dotted with trees—rare in Sri Lanka but intact here at Nilgala :contentReference[oaicite:1]{index=1}.
  • Granite hillocks and caves that serve as microrefugia for rock-dwelling species.

Endemic Reptiles and Amphibians

Among Nilgala’s most special inhabitants are gecko species found nowhere else:

  • Nilgala day gecko (Cnemaspis nilgala): Discovered in 2019, known only from rock caves across Nilgala, with adult size ~32 mm SVL :contentReference[oaicite:2]{index=2}.
  • Cyrtodactylus vedda: Another endemic species thriving in isolated rocky habitats there :contentReference[oaicite:3]{index=3}.

Nilgala hosts Cnemaspis nilgala in a highly restricted range across six rocky locations spanning about 40 km² :contentReference[oaicite:4]{index=4}. It shares habitat with other micro-endemic geckos, bats, amphibians, and a striking reptile community adapted to the forest-savanna gradient.

Flora of Royal and Medicinal Value

Nilgala is also home to plants historically revered in Ayurvedic medicine—including some once used in royal confections—woven into local spiritual practices :contentReference[oaicite:5]{index=5}.

A Sanctuary of Culture: The Vedda Connection

The ancient Vedda community regards Nilgala not merely as land but as the sacred dwelling place of their ancestors.

“To the Vedda community, Nilgala is not just a forest, but a sacred living space where the spirits of our ancestors dwell.” – Suda Vanniyalaathto, Vedda clan chief :contentReference[oaicite:6]{index=6}

During the proclamation on June 2, Vedda performers danced the Kiri Koraha dance, honoring the forest guardians in a spiritually resonant ceremony :contentReference[oaicite:7]{index=7}. This deep cultural bond shaped decades of conservation efforts alongside environmental NGO campaigns.

From Confrontation to Conservation: The 2014 Tree-Ordination

In 2014, as the threat of large-scale plantations emerged, Buddhist monks—supported by NGOs like the Centre for Environmental Justice—ordained over 1,000 trees in Nilgala. Enrobed in saffron, these trees were spiritually protected from being cut, a powerful act of ecological resistance :contentReference[oaicite:8]{index=8}.

Since then, local Vedda guardians and community-based forest committees have acted as first responders to illegal logging, fire, and land grabbing—forming the backbone of on-the-ground protection :contentReference[oaicite:9]{index=9}.

Declaration Day: June 2, 2025

Timed with World Environment Day and Sri Lanka’s National Environment Week, the formal declaration at Ratugala Indigenous Heritage Centre was led by Minister of Environment Dr. Damitha Pathabendhi (Hettiarachchi) :contentReference[oaicite:10]{index=10}. Government announcements confirmed the reserve covers ~40,683 ha—validated by Mongabay and local press :contentReference[oaicite:11]{index=11}.

Why Nilgala Matters Ecologically

  • It’s Sri Lanka’s **largest intact savanna–forest mosaic** preserved in its natural state :contentReference[oaicite:12]{index=12}.
  • Serves as a **climate refuge** for plants and animals adapted to different microhabitats.
  • Protects newly described endemics—like the Nilgala day gecko and other micro-reptiles—and supports globally vulnerable species.

Conservation Challenges & Future Vigilance

Despite the protected status, Nilgala still faces:

  • Illegal land encroachment driven by agriculture or powerful vested interests :contentReference[oaicite:13]{index=13}.
  • Risks from large-scale monoculture proposals for pineapple, sugarcane, and bananas :contentReference[oaicite:14]{index=14}.
  • Forest fires, both natural and human‑induced—Nilgala’s dry grasses are fire-prone :contentReference[oaicite:15]{index=15}.
  • Scrutiny of governance: The effectiveness of forest-guard and NGO patrols will be key to long-term success.

Linking with Broader Conservation Efforts

Nilgala’s protection complements Sri Lanka’s national biodiversity strategies aimed at conserving diverse ecosystems, especially in the dry and intermediate zones. It connects with:

  • Global Mongabay coverage, raising awareness of local conservation action.
  • Local media networks—like Newswire.lk, Daily Mirror, Ceylon Today—highlighted declaration coverage :contentReference
  • Past herpetological studies—such as Suranjan Karunarathna’s 2019 discovery of Cnemaspis nilgala :contentReference

How You Can Support Nilgala Conservation

  • Support NGOs like the Centre for Environmental Justice.
  • Donate or volunteer with Vedda-led forest monitoring groups.
  • Spread awareness via social media platforms.
  • Engage with local tourism providers offering guided visits—choose ecologically sensitive operators.

Key Takeaways

  • ~40,000 ha of prime savanna ecosystem now legally protected (declared June 2, 2025).
  • Rich mosaic of forests, grasslands, wetlands, granite hills, caves—supports rare biodiversity.
  • Home to newly described species like the Nilgala day gecko (Cnemaspis nilgala), found only here.
  • Deep cultural roots: The Vedda people maintain spiritual ties to this ancestral landscape.
  • Long-fought battle involving Buddhist monks, NGOs, and communities culminated in the tree-ordination protest and legal protection.
  • Future success depends on vigilance: preventing land grabbing, enforcing laws, supporting local governance.
