Forestry officials have restored a damaged stream in central Finland. The work took place at Tamaranpuro creek in Kangasniemi municipality. This stream forms part of the headwaters of Lake Puula.
Workers returned approximately 10,000 kilograms of gravel to the waterway. They also reshaped the stream channel to create a more natural flow. The restoration included building gravel beds for migratory fish to spawn.
Historic log floating operations had previously damaged the stream. Workers straightened the channel and removed stones decades ago to transport timber. These modifications harmed aquatic habitats over time.
The restoration aims to improve living conditions for stream organisms. Better habitat should support insects, fish and other freshwater species. Officials hope the work will boost local biodiversity.
This type of environmental restoration represents a shift in Finnish forestry practices. While log floating was essential for past timber transport, current management increasingly prioritizes ecosystem health alongside timber production.
