Restoring the Zwalm catchment in Belgium

After degradation of the river due to straightening, bank enforcements, navigational use and intensive agricultural land use along its banks, the Zwalm river basin is now to be restored at several sites. The case study aims at restoring the river to a healthy and functioning ecosystem while still allowing navigational use. A focus is on habitat restoration (spawning beds, buffer strips) and passability for fish.

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape...

Upscaling the Tzipori river restorations in Israel

Tzipori river, Israel

After a decade of restoration measures along the Tzipori stream in Israel, this case study will monitor their success and aims at upscaling measures to the watershed scale in order to create a model for management of stream basin rehabilitation.

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: INnovation, upscaling and transformation.

Greening the Sorraia valley floodplain

Implement the best configurations for greening elements (type, location, spatial configuration),  in the Sorraia floodplain valley, that maximize biodiversity (woody structure, ants, birds and chiropterans) and ecosystem services (biological control, nutrient and sediment removal, pollination, habitat for species) without detriment of economic incomes for farmers.  During the planning stage, a model for optimization will be developed, and different scenarios of agriculture development and global changes tested, together with stakeholders and administration.  

This case study is one...

Floodplain restoration in the Lima catchment, Portugal

After around 21ha of floodplain area were passively and actively restored under the LIFE FLUVIAL project, an enlarging of the intervention area is now being implemented. The floodplain forest restoration intends to develop/demonstrate an ecological restoration approach for fluvial floodplains transferable to lowlands at the biogeographic region (NW of Iberian Peninsula). The case study also aims at taking local stakeholders on board and reconcile the protection of priority habitats with traditional cattle production. The case study will also integrate an educational dimension and aims at...

Monitoring the success of Liberty Island, Hungary

Liberty Island in the Danube River, Hungary

The creation of a long-term, sustainable conservation model for white willow (Salicion albae) alluvial forests in Hungary and a more near-natural flow regime of the Danube. A core aim was to eliminate or mitigate the factors that threaten the habitats of community interest. 

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: INnovation, upscaling and transformation. Within MERLIN, the project area of the Liberty Island restoration is revisited to learn from...

Restoring Danube floodplains in Romania

Garla Mare Romania

Former wetlands adjacent to the river are being reconnected to demonstrate the benefits of re-wetting /reconnection to the natural flood pulse of the Danube River in order to enhance the benefits provided to nature and local communities.

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: INnovation, upscaling and transformation.

Restoring Danube floodplains in Austria

Riverbank restorations are implemented on a stretch of approximately 800m shoreline of the Danube to increase lateral river-floodplain connectivity and the functioning of the floodplain as an ecosystem. The aim is to reach a good ecological status of the river as well as good navigation status. The case study works with an adaptive management process and adresses multiple pressures (ecological deficits, security of navigation, riverbed deepening, flood protection).

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration...

Kristianstads Vattenrike - Sweden’s oldest UNESCO biosphere reserve

In 2005, the UN agency UNESCO approved Kristianstads Vattenriket as a biosphere reserve covering 100 000 ha, and one of 700 in the world. This means Kristianstads Vattenrike is an internationally recognized  model for sustainable development. The Vattenrike encompasses two thirds of the municipality of Kristianstad, with the goal to “preserve, develop and support the landscape's values”. 

Nature-based solutions have been key for protection against droughts, floods, and preservation of the area, as well as nutrient leakage into the Baltic Sea.

The areas in Vattenriket include...
