Sečoveljske soline Landscape Park (Krajinski park Sečoveljske soline) is a protected area of the Sečovelje Slat Plans - one of the last manually-operated salt pans in the Mediterranean, employing a centuries-old method for salt extraction. This traditional, nature- and human-friendly approach has fostered unique ecosystems in and around the salt pans, showcasing the harmonious coexistence of nature and mankind.
The origins of the salt pans likely date back to the Roman Period, possibly forming at the mouth of the River Dragonja. However, it is certain that they were established during the Middle Ages. Over time, human interaction played a considerate role in shaping the salt pans. Remnants of medieval salt panning can be observed in the ruins of former salt pan workers' houses in the southern part of the park, known as Fontanigge. Salt collection ceased in the mid-1960s, except on Lera in the north, where salt production has persisted, preserving medieval patterns and methods.
The vast, shallow water areas, embraced by the sub-Mediterranean climate, have always teemed with life, not only with salt pan workers but also with animals and halophyte plants thriving in the saline environment. In autumn, many of these plants turn red as they extract nitrogen from the nutrient-poor soil.
The saline habitat is a haven for birds, with 296 species identified so far. Various biotopes in the channels and pans create an exceptional habitat for bird species seeking refuge or nesting grounds. The salt pan channels and tepids are home to the South European toothcarp, and in the summer, visitors may spot small, red-colored brine shrimp, each slightly over a centimeter in size, thriving in the salty waters.
