tuleallikas

A tuleallikas, commonly known as a sedge spring or fen, is a type of wetland ecosystem characterized by the presence of water-saturated ground and the dominance of sedges (genus *Carex*) and other moisture-loving plants. These ecosystems are typically found in regions with high precipitation or poor drainage, where water accumulates near the surface. Tuleallikad are particularly common in boreal and temperate zones, including parts of Europe, North America, and Asia.

The water in tuleallikad is often acidic and nutrient-poor, which creates unique conditions for plant and animal life. Unlike peat bogs, tuleallikad are generally more open and less woody, with a mix of grasses, sedges, and occasional shrubs. They serve as important habitats for various species, including amphibians, insects, and birds, such as moorhens and snipe. Some tuleallikad also support rare or endangered plants and animals, making them ecologically significant.

In Finland, tuleallikad are particularly notable due to their cultural and historical importance. They have been used for centuries as sources of peat, a fuel material, and as grazing areas for livestock. Traditional Finnish agriculture often relied on these wetlands, where farmers would drain and manage the land to create fertile meadows. However, due to drainage for agriculture and urbanization, many tuleallikad have declined in size and number.

Conservation efforts focus on protecting remaining tuleallikad by restoring drained areas and preventing further habitat loss. These wetlands play a crucial role in maintaining biodiversity, regulating water flow, and mitigating climate change by storing carbon. Their preservation is essential for both ecological balance and cultural heritage.
