Islas y Canales Verdes of the Uruguay River: a new protected paradise in Entre Ríos

Located in the heart of the Uruguay River, the Provincial Natural Park Islas y Canales Verdes protects more than 4,000 hectares of islands, wetlands, riparian forests, and channels. Officially created in 2023, it has quickly become a milestone in Argentina’s conservation history, combining biodiversity protection, eco-tourism, and community engagement.

Unique biodiversity

The park safeguards diverse ecosystems that host remarkable wildlife:

• Birdlife: over 200 species, including roseate spoonbills, herons, kingfishers, and migratory flocks.
• Flora: riparian forests of willows and alders, along with aquatic vegetation that regulates floods and ensures water quality.
• Fauna: capybaras, otters, amphibians, and a wide diversity of fish typical of the Uruguay River basin.

Its wetlands also play a crucial role in flood regulation and water purification, making them vital for both nature and people.

History of creation

The Provincial Natural Park Islas y Canales Verdes was officially created in November 2023 through a decree by the Government of Entre Ríos and ratified by provincial law in 2024. Its creation was possible thanks to a public-private alliance:

• WCS Argentina: scientific research and conservation planning.
• Banco de Bosques: land acquisition and donation of strategic islands.
• Local communities: participation in management and future ecotourism development.
• Butler Conservation Foundation: international funding that made land purchase and protection possible.

This collaborative effort marks a new era of conservation in Argentina’s littoral region.

Conservation impact and eco-tourism

The park offers experiences that combine adventure, learning, and nature connection:

• Kayaking: explore channels and islands in our guided trip Islas & Canales del Río Uruguay – November 2025.
• Birdwatching: a hotspot for naturalists, birders, and wildlife photographers.
• Environmental education: initiatives like “Kayaks for Schools” involve students and teachers in hands-on conservation.
• Hiking: interpretive trails through wetlands, beaches, and riparian forests.

Future plans include visitor centers, interpretive trails, signage, and eco-friendly camping areas.
