Luontokäytävä

Luontokäytävä, also known as a nature corridor or wildlife corridor, is a protected strip of land that connects two or more habitats. These corridors are designed to allow wildlife to move between these separate areas, facilitating gene flow, migration, and the maintenance of viable populations. They are crucial for species that require large territories or are sensitive to habitat fragmentation.

The concept of luontokäytävä is a key tool in conservation biology and landscape planning. Habitat fragmentation, caused by human activities such as urbanization, agriculture, and infrastructure development, breaks down large, continuous habitats into smaller, isolated patches. This isolation can lead to reduced genetic diversity, increased vulnerability to local extinction, and disruption of ecological processes. Luontokäytävä aims to mitigate these negative effects by providing safe passage for animals and plants.

Luontokäytävät can vary greatly in size and design. They can be natural features like river valleys, forest strips, or hedgerows, or they can be engineered structures such as underpasses or overpasses for roads. The effectiveness of a luontokäytävä depends on its connectivity, width, habitat quality, and the species it is intended to serve. Successful implementation requires careful planning and consideration of the specific ecological needs of the target wildlife. Preserving and establishing these corridors is a vital strategy for biodiversity conservation in increasingly human-dominated landscapes.
