Diverse vegetation is also resilient and adapts to changes in land-use and variation in weather conditions. The extent of the services that wetlands provide to people depend on wetland design and well-being, as well as on land-use within the contributing watershed and weather dependent pollutant loads. Constructed wetlands typically consist of a flow dissipating and heavy sediment settling inlet pond, a vast shallow emergent plant covered wetland, and a sediment settling outlet pond. The Säynäslanhdenpuro Wetland consists of three parallel research wetlands with flow and pollutant load monitoring facilitating outlet dams.

A stormwater wetland is a constructed transitional landscape between water and dry land. Wetlands are natural water detention and purification landscapes. Constructed wetlands are thus established to compensate for challenges to water environment brought about by land-use change. Urban wetlands dissipate and detain runoff thereby preventing flooding and drought extremes. Water quality is mitigated through sediment settling, and purification of soluble pollutants by wetland plants, microbes and soils. Diversity of plants and their associated microbes is a key element in purifying urban waters.

Land-use change in urban areas from natural to impervious surfaces such as roofs, paved yards and asphalt roads prevents water infiltration and storage within the watershed. Runoff travels quickly over impervious surfaces collecting and carrying everything from surfaces to catch basins and sewers. Impacts visible at the storm sewer outlets to urban streams include flooding, drought and erosion. Depending on land-use within the watershed, runoff carries harmful substances such as nutrients, heavy met- als, oils and rubbish. The receiving water body suffers from habitat degradation while the impervious and drained watershed often experiences draught and heat.

The Imatra Rapids are one of Finland's oldest tourist attractions, dating back to the 1700s. The Imatra Hydroelectric Dam was built in 1929. It a hugely impressive sight, a highlight of any run here.

In the northeast of Helsinki's Central Park, Niskala arboretum is a great place to explore. Over 750 different species can be found here and the wildlife wonderfully vibrant.

Högberget is a particularly panoramic part of the Sipoonkorpi National Park. You can ascend above the trees to its rocky apex and survey the surrounding landscape. The paths here make for great trail runs, with quite a few undulations but nothing too challenging.

Very nice route walked of about 5 km. (The white/green signs) route goes over rocks and tree stumps and therefore not suitable for someone who is not very mobile. Along the way you will come across a picnic spot. Enjoy this beautiful route!

Imatrankoski is one of Finland’s most famous rapids and a highlight of any visit to Imatra. The dam-controlled rapids are usually opened in summer for scheduled shows, drawing crowds to watch the powerful flow of water through the old riverbed. It’s located right in the city centre, with good bike access and plenty of space to watch from the bridge or park area. The surrounding Kruununpuisto Park is Finland’s oldest nature park and offers well-kept paths and historical landmarks. It’s a great place for cyclists to stop, explore on foot, and enjoy both natural force and local history.
