Ongoing projects

EKOenergy’s Environmental Fund finances various river restoration projects each year every year. The project duration varies from one to three years. See hereafter an overview of the ongoing projects.

 

Raising young freshwater pearl mussels

We gave 24,000 € for raising the young freshwater pearl mussels and other protection measures (University of Jyväskylä): A follow up project for “Hunting the lost pearl” which EKOenergy has previously financed. The project also aims to start mapping possibilities for their return to nature.

 

Maijalankoski project

25,000 € for river restoration measures in Maijalankoski (The Finnish Society for Stream Conservation, Virho) : The Maijalankoski rapid is no longer a productive area for fish and its biodiversity could be considerably improved. This project will support various river restoration activities, which would help enable the future reintroduction of salmon and freshwater pearl mussel.

 

Mommolankoski project

12,500 € for a fish passage at Mommolankoski (Valonia): In the river Mommolanjoki there are three migration obstacles for migratory fish. This application is aiming to bypass the first obstacle coming from the river mouth.The main goal of this project is to design a fishway to the Mommolankoski dam. The fishway will be built after this project depending on funding and licences.

 

Sierilä rowing event

6000 € for a campaign at Sierilä, Kemijoki river (SLL Rovaniemi): Kemijoki is a heavily constructed river used for hydropower generation. With it’s unique sandy river banks, is home to the last surviving populations of many endangered plant and insect species. The aim of this project is to raise awareness about and prevent the building of the Sierilä dam on the last pristine stretch of the river Kemijoki. This is the continuation of the previously funded project.

 

Stream restoration in the Lake Näsijärvi catchment area

The aim of the activities is to re-establish brown trout populations in the Lake Näsijärvi cathcment area. The restoration works by volunteers have already been started in the streams, including cleaning up the spawning gravels, inventories of relevant sites, helping with egg box plantings and consulting local fishermen. Present target areas include the streams in the catchment area of Lake Näsijärvi and upstream from it, in the Ruovesi-Kuorevesi area. The funds will be spend on machine work, gravel, travelling and electric fishing controls, while the work is done on voluntary basis. Tens of volunteers participate in the activities.

Hunting the lost pearl

The purpose of the project is to improve the conservation status of the endangered freshwater pearl mussel (Margaritifera margaritifera). The goal of this project is to develop a tool to identify the potential rivers and streams that could be suitable for freshwater pearl mussels, in order to establish protection measures and priority areas for conservation and/or restoration initiatives. A geographical information system platform will be developed and tested in the Hämeenkyrö municipality area. The only two currently known recruiting populations are found in Hämeenkyrö. Stream Ruonanjoki has a rapidly declining population and the stream Turkimusoja freshwater pearl mussel population was discovered very recently (2014). It is probable that small populations still exist but they are not known.

The freshwater pearl mussel used to be widely distributed in the rivers of the northern hemisphere from west/north-west Europe to eastern North America. However, due to a steep decline, it is estimated that the mussel is now present in 5% of its former range. The life cycle of the freshwater pearl mussel is complicated by the presence of the parasitic glochidial stage. Survivorship of this stage depends on locating a suitable host fish and the subsequent settlement of the post glochidial stage in a suitable habitat. The only suitable hosts for the mussel are the brown trout (Salmo trutta) and Atlantic salmon (Salmo salar), which have been impacted by hydropower and dams. Results from river surveys in Europe indicate that there is no recruitment in most rivers and there has not been any for tens of years. It is estimated that a great majority of the populations are in terminal decline. The freshwater pearl mussel is a flagship and umbrella species that in the past has populated and purified the water of rivers all over Europe. Today it is Critically Endangered (IUCN) and its EU conservation status in all biogeographical regions is Unfavourable-Bad. The mussel has almost disappeared from Southern Finland where it used to be abundant.

Let migration be free

Migrating fishes are endangered, and many populations are close to extinction in Finland’s archipelagos due to man-made barriers on their migration routes, habitat degradation, poor water quality and overexploitation. The migration barriers in the rivers flowing to the Archipelago Sea are mainly old unused mill dams and culverts. There are estimated to be more than 100 migration barriers in South-West Finland’s streams.

Most of southwest Finland’s trout (Salmo trutta) populations have become extinct or are very small due to hydropower plants, dams and dredging of streams. However, some genetically original trout stocks have survived in the Rivers of Southwest Finland.

The project goal is to enhance these extremely endangered trout stocks through the removal of migration barriers and restoring trout habitats in Southwest Finland. The project aims to improve habitats of the endangered Sea Trout and other endangered species aiming to actually prevent the extinction of some of the last native sea trout populations. The project will also raise public awareness about migratory fishes and stream restorations.

Fisheries restoration in River Isojoki

River Isojoki is located in Central Finland. Brown trout and graylings reproduce naturally in the river but the reproduction can be enhanced with restoration. The measures include enlarging the areas with bottom substrate suitable for spawning and safeguarding water levels during dry seasons. The restoration measures will mainly be done in the downstream areas within a 6,5 km route Jokirinne-Pyyrinlahti close to lake Keitele. Restoration will be done both with machines and by manual labour.

Connection of a meander in Schnegaer Mühlenbach

The “Schnegaer Mühlenbach“ is a fast flowing and quite natural small river, meandering in wet lowlands, which has its source in the uplands and is therefore cold in summer. Formerly, the Mühlenbach was used to drive water mills with the effect of reducing the natural state in some sections.

Characteristic for the biological importance of the river are its gravel banks, the rich and vast moist meadows and the adjoining old softwood riparian forests, habitats of a rich fauna and flora. Also noteworthy are the numerous sources, where the fire salamander (Salamandra salamandra) – a rare amphibian in the northern lowlands – has remarkable populations. Some fauna of the Schnegaer Mühlenbach itself are freshwater crayfish (Astacus astacus), a rare mussel (Unio crassus), trout (Salmo trutta) and the otter (Lutra lutra).

Since the meander, which was formerly part of the Schnegaer Mühlenbach, was cut off, the river was straightened and lost its gravel banks. The original shape of the meander can still be seen as a basin-shaped depression in the ground. The former meander has the remarkable length of nearly 200 metres, meandering through a large variously wooded area.

It is necessary to connect the meander, which is now totally dry, with the Schnegaer Mühlenbach again, and also to give the stolen gravel banks back to the river. These steps will be essential elements for a better ecological morphology of the Schnegaer Mühlenbach. The project includes the concrete connection and restoration work of the meander, according to the plans. The project budget includes the costs of the excavator and gravel needed.

Bless the Sieriniemi – Rowing event for the last remaining free-flowing part of River Kemijoki in 19.-23.7.2018

The aim of the event is to prevent the building of the Sierilä dam on the last unconstructed stretch of the river Kemijoki. The sandy river bank at the planned Sierilä power plant is home to the surviving populations of many endangered species. For example, a rare butterfly, the scholarly herd (Capricornia boisduvaliana), is only found in Finland in this specific area. For more information see https://www.sll.fi/mita-me-teemme/vedet/vapaakemijoki. The project costs include planning, organisation and the realisation of the rowing event Sieriniemen soutu in Rovaniemi 19.-23.7.2018. The organiser is the local nature conservation society in Rovaniemi in co-operation with the local association Oikarainen. A steering group and a media planning group have been established to support the project. Publicity and visibility in the media will play a key role in the project.

Let River Mustijoki be a living river for salmon

The final aim of the project is to re-establish a route for migratory fish such as seatrout, fromdownstream areas to upstream areas where larger spawning areas are now located behind a dam. A proper fishway plan and a 3-year study are needed to make progress towards this goal. The money will be used as seed money for fostering these plans, finding further funding and relevant participants.

Free waterways in the Kokemäenjoki catchment area

Kokemäenjoki catchment area is located in South-West Finland, mainly in the Pirkanmaa county. The target areas of the project are selected on the basis of earlier distribution and genetic studies of the brown trout populations in the catchment area. The ultimate goal of the project is to re-establish river connectivity to enable the expansion of the genetically original trout populations. The information on the existing sub-populations of brown trout is used to further develop other measures for the benefit of the fish.

The 2-year project includes concrete river restoration and fish migration study in this catchment area, in the Pirkanmaa county. The restoration includes eliminating migration obstacles and restoring spawning areas. At the same time a study of the migration of naturally reproducing trout populations is carried out.

Funding granted from EKOenergy Environmental Fund: 50 000 euro, to be used in 2017-2018 for specific river restoration measures and migration studies.

 

Developing a new fish passage type

A remarkable challenge of fish passage planning is the task of creating a sufficient attraction flow that would show the animals the direction to the fish passage. In hydropower plants operations water is a resource to be used for electricity production and thus to be used effectively. On the other hand, in many plant operation bypass flow – the excess water that cannot be used in turbines to generate electricity – occurs regularly during the fish migration time in spring and autumn. In current fish passage installations (in Finland and internationally) the bypass flow is not utilized for the benefit of the fish. The goal of the project is to create a new fish passage type that would utilize this opportunity, especially with regards to upstream migration but to some extend also downstream migration.

Restoring river habitats in River Merikarvianjoki

River Merikarvianjoki is located in the Satakunta county. The brown trout population of the river suffers from the lack of reproduction areas. The restoration project will focus on the replacement of unsuitable sharp-shaped bottom stones with natural-like gravel and rock material. It is possible that also salmon and whitefish populations will benefit from this restoration.
