Take Alam-Pedja Nature Reserve in Estonia—what makes it so special? Established in 1994, it protects one of the country"s largest and most intact wetland systems, where rivers like the Pedja and Põltsamaa still flow freely. The 342-square-kilometres reserve is a haven for wildlife. Moose roam the wetlands, lynx move through dense forests and rare birds such as the black stork and lesser spotted eagle nest in its quieter corners. With limited human settlement, much of the area remains untouched—no large-scale farming, no urban spread. Seasonal flooding reshapes the landscape, renewing habitats and sustaining rich biodiversity year after year.
