|Project summary=The interventions carried out on the Montone river are part of a general project dating back to the '90s called "Fiumi Puliti” (Clean Rivers); the main goals of that project were the “maintenance” of river beds of the Romagna area, the reduction of flood risk and the implementation of the Montone River Natural Park, in the Municipalities of Forlì and Castrocaro.
The main tool put in place to achieve these objectives was to return to the river part of the floodplains, both public domain and private, that had been separated from the river due to the construction of embankments. Since 1992, this strategy has allowed to recover, within a relatively short stretch of the river, a storage capacity of more than 2,500,000 m3. This space was returned to the natural flood dynamics lowering the alluvial plane and/or displacing the embankments to the external borders of the floodplain.
In the area just upstream the confluence with the Rabbi Stream, the works included the removal of some embankments (in red in the picture) and the reconstruction of a portion of an embankment in a backward position (in green). It is foreseen to remove further embankments (in yellow), so as to ensure to both rivers a wider speace for hydromorphological dynamics.

|Project summary=The Beaume river, a tributary of Loire river, is 10 kilometers long; 2,7 Km before the confluence with the Loire, the river forms a natural waterfall 27 meters high. The ecological quality of rivers is quite good.
In 1907, a 6.10 meters height dam is built, for the hydroelectric power plant of Fatou. The utilization of this plant stops in the sixties. The dam blocks the ecological continuity.
Approximately 6,000 m3 of sediment has accumulated behind the dam.
During 1985 the dam has become public property.
For security reasons related to poor condition of the structure, it is decided to erase it.
The work consists on the completely removal of the dam and factory building.
|Monitoring surveys and results=After works, the natural water line is restored and the vegetation along the Baume river is naturally quickly restored.
At present, an evaluation is not possible due to the limited data availability. However, the initial results are very encouraging.

|Project summary=The Ouche River is a 95 km long tributary of the Saône. His watershed, 916 km2, is predominantly agricultural.
The river is channelized on several sectors in order to increase the flow velocities and prevent flooding risk. Many bank protection and dikes were put in place. Due to the river dynamic, it is necessary to consolidate and strengthen the bank protection regularly
In 1992-1993, the General Council decided to take action to limit the interventions for banks protections strengthening. In 1995, a study identifies riparian areas that may be acquired.
The sector concerned presents few facilities and dams already damaged by the dynamics of the river.
3.4 hectares of land on the right bank, corresponding to a band 50 m wide, are acquired. The bank protection are not deleted because they are already severely degraded by the flow dynamics. However, actions are taken to sensitize residents to the non-interventionist approach. Landowners are compensated.
|Monitoring surveys and results=This allows to increase the diversity of habitats. Some alluvial deposits were created and riparian vegetation has developed.
The fish monitoring show a very important increase in the diversity of fish.

|Picture description=The Montvaux stream before and after restoration works.
|Project summary=The Montvaux stream, is a 10 Km long tributary of the Moselle.
Upstream of the municipality of Châtel-Saint-Germain, this river still has good hydromorphological characteristics. Conversely, crossing the urban area of Châtel-Saint-Germain, the river was straightened, the banks were stabilized by the creation of a concrete channel, with a rectangular oversized (5 to 6 meters wide)cross-section .
Originally, these works allowed to create storage pools in order to feed mills and forges.
Afterwards, as a result of the uptake of the main sources in the valley for drinking water supply, the water depth at low water had become very low, reduced to 1-3 centimeters. This induced reduction of the aquatic habitats, eutrophication of the environment and bas smells. The substrate of the bottom of the bed, the flow speed and the bed depth were homogenized, degrading habitats and preventing the development of aquatic life.
Faced with the deterioration of the watercourse, both in terms of landscape and of morphological and biological features, the municipality of Châtel-Saint-Germain decided to undertake a restoration project.
The works included the redesigning of a meandering low flow channel and the introduction of benches. The low-flow channel was made using topsoil wrapped in coir geotextile. The banks were seeded with a mixture of grass species and about 700 helophytes were planted the following year.
|Monitoring surveys and results=After project management was reduced to a biennial cutting of the banks vegetation and, when needed, removal of waste (plastic, etc…) and of major obstacles to the flow.
A preliminary study was carried out in 1996. After works, no scientific monitoring was planned, but the river banks were vegetated and the diversification of flows and bed depth was ensured. There were no longer stagnant water or siltation.

|Project summary=The Ministry of Agriculture, Food and Environment launched in 2007 the National Strategy for River Restoration to, in keeping with the Water Framework Directive, achieve a good ecological status of rivers. One of the main lines of action is the demolition of transversal obstacles that are in a state of abandonment and have a great impact on the longitudinal connectivity of rivers.
In the Duero River basin, more than 80 obstacles have been demolished in recent years. During the months of February and March of 2013,
the works to demolish the Retuerta Dam, on the Aravalle river, located in the municipality of Umbrías (province of Ávila) took place. The dam was approximately 14 metres in height and 55 metres in length, making it the highest dam demolished to date. The removal of this dam was contemplated as a compensation measure in an Environmental Impact Statement, with the purpose of recovering the longitudinal connectivity of the Aravalle River in this stretch, which constitutes a rich fluvial ecosystem, torrential in nature, and with abundant ichthyofauna. In fact, the Aravalle River is one of the most relevant watercourses for sustaining fish populations within the Tormes River system.
There has also been work related to monitoring the mobilization of sediments and the recovery of the fluvial ecosystem, as well as public information and participation seminars.

Case study:Habitat Management and Raptor Conservation in Nestos Delta and Gorge - LIFE02 NAT/GR/008489

|Project summary=The River Nestos is 230 km long, flowing from the Rila Mountains into the Aegean Sea through Bulgaria and northern Greece. Before it reaches the sea, the main river spreads over the coastal plain of Chrysoupolis and expands as a deltaic system with freshwater lakes and ponds forming the Nestos delta. The river also traverses a unique gorge towards the end of its course, which is home to many raptors, including the Griffon vulture (Gyps fulvus).
The delta comprises extensive sand dunes, residual riparian forest, lagoons, water meadows and other important habitats for birds and various mammals such as the otter and the jackal. It has been classified as a wetland of international importance (Ramsar site) and the gorge as an "Aesthetic forest" in accordance with national forestry legislation. The region has the most extensive riparian forest in Greece. The complex mosaic of habitats gives the region particularly rich biodiversity, but there are major problems, the main of which are: the lack of water resource management; the expansion of agricultural activities; species disturbance by various human activities; the degradation of key habitats, such as breeding islands in the lagoons; and various illegal activities, such as poaching or use of poisoned baits.
The main goal of the LIFE project carried out between 2002 and 2006 was the protection and management of raptors and terns and their habitats in three sites across two neighbouring Natura 2000 Special Protection Areas along the River Nestos.
The project targeted improved management of water resources. It sought to achieve this by reconnecting tributaries at four points on the river in order to restore some of the functions of the natural ecosystem, including freshwater marshes and riparian forests.
It also specifically aimed to restore around 35 hectares of riparian forest in such a way as to join up the remaining forest sections.
At the same time, the project wanted to implement activities for specific bird species, including a system of artificial feeding for vultures in the Nestos gorge and rehabilitation of breeding islands for pelicans and terns in the lagoons.

Human activities would be controlled by setting up a surveillance team and by reducing fishing in return for compensatory measures for fishermen. Nature trails were to be constructed to improve understanding by the public of the valuable ecosystems and to allow controlled human interaction with the habitats.

The project reforested 60 ha of natural riparian forests on former agricultural land.
Based on detailed mapping research, four old river branches were reconnected with the main river to enable the recovery of freshwater marshes and riparian forests. The reconnections allow for groundwater recharge and protect against salt-water intrusion at the river mouth, thus enhancing the habitat for aquatic species such as water turtles, otters and fish species.

Eight specially designed fenced floating rafts - 5x4 m - were installed in the lagoons of the Nestos delta to provide roosting and nesting sites for terns. The rafts were immediately used by terns in the breeding season. They were especially designed and constructed to deter land predators such as stray dogs or jackals from accessing the nests and this has been seen to be effective.

The preparatory studies and scientific work of the project partners was of excellent quality. Automatic water and sediment monitoring stations were installed at a lagoon and at the main river stream to provide continuous data which is sent automatically to the Fisheries Research Institute of the National Agricultural Research Foundation.

A fenced feeding site was set up for birds of prey to replace natural prey that have declined in numbers. This was especially targeted at the griffon vulture colony residing on the cliffs of the Nestos gorge as well as vulture populations nesting in Dadia and Bulgaria. Unfortunately, delays in establishing the site meant that regular feeding of the vultures did not take place during the project's duration.
Problems were experienced in cooperation between local authorities - and with the national authorities. This contributed to delays in the construction of a stone observation hide opposite the feeding site - to observe the vultures without disturbing them - and prevented the successful development of other planned visitor infrastructure during the timeframe of the project.

The main goal of the LIFE project carried out between 2002 and 2006 was the protection and management of raptors and terns and their habitats in three sites across two neighbouring Natura 2000 Special Protection Areas along the River Nestos.
The project targeted improved management of water resources. It sought to achieve this by reconnecting tributaries at four points on the river in order to restore some of the functions of the natural ecosystem, including freshwater marshes and riparian forests.
It also specifically aimed to restore around 35 hectares of riparian forest in such a way as to join up the remaining forest sections.
At the same time, the project wanted to implement activities for specific bird species, including a system of artificial feeding for vultures in the Nestos gorge and rehabilitation of breeding islands for pelicans and terns in the lagoons.

Human activities would be controlled by setting up a surveillance team and by reducing fishing in return for compensatory measures for fishermen. Nature trails were to be constructed to improve understanding by the public of the valuable ecosystems and to allow controlled human interaction with the habitats.

The project reforested 60 ha of natural riparian forests on former agricultural land.
Based on detailed mapping research, four old river branches were reconnected with the main river to enable the recovery of freshwater marshes and riparian forests. The reconnections allow for groundwater recharge and protect against salt-water intrusion at the river mouth, thus enhancing the habitat for aquatic species such as water turtles, otters and fish species.

Eight specially designed fenced floating rafts - 5x4 m - were installed in the lagoons of the Nestos delta to provide roosting and nesting sites for terns. The rafts were immediately used by terns in the breeding season. They were especially designed and constructed to deter land predators such as stray dogs or jackals from accessing the nests and this has been seen to be effective.

The preparatory studies and scientific work of the project partners was of excellent quality. Automatic water and sediment monitoring stations were installed at a lagoon and at the main river stream to provide continuous data which is sent automatically to the Fisheries Research Institute of the National Agricultural Research Foundation.

A fenced feeding site was set up for birds of prey to replace natural prey that have declined in numbers. This was especially targeted at the griffon vulture colony residing on the cliffs of the Nestos gorge as well as vulture populations nesting in Dadia and Bulgaria. Unfortunately, delays in establishing the site meant that regular feeding of the vultures did not take place during the project's duration.
Problems were experienced in cooperation between local authorities - and with the national authorities. This contributed to delays in the construction of a stone observation hide opposite the feeding site - to observe the vultures without disturbing them - and prevented the successful development of other planned visitor infrastructure during the timeframe of the project.

|Project summary=Due to the proximity to populated areas, the stream of Can Sunyer is highly anthropized, being able to observe various species in the exotic gardens, among other pressures. Despite that, the stream preserved in some sections a remarkable environmental and scenic quality that deserves to be preserved and enhanced.
The main objectives in this project are: to preserve natural systems typical of wetland and fluvial ecosystems, especially the riparian forests; to prevent and eliminate existing impacts on banks of the stream; facilitating access of visitors to the area, reporting the ecological and social landscape of the place; to provide an area of natural interest for environmental education.
The project has a total budget of 42.980,61 € and is financed by Natura Foundation, Municipality of Martorelles and Laboratorios Esteve S.A.

{{Project overview

|Main contact forename=Barbara

|Multi-site=No
|Project summary=The river Toce in the Alps is the next largest tributary of Lake Maggiore after the river Ticino. It is a very important site for nesting birds and especially migrating birds including priority species, such as the corncrake (Crex crex). The Toce fulfils a vital role as an ecological corridor across the Alps during bird migration.
The project aimed to help the conservation, rehabilitation and extension of the river and riverbank habitats along a stretch of the river Toce downstream Domodossola.
The project achieved some relevant results such as the creation of an area with different water levels down to a maximum depth of 1 m, thus favouring amphibians and birds in the locality of Prata (Municipality of Vogogna); the reduction of the presence of invasive exotic trees and shrubs in termophilous shrub habitats; the maintenance of suitable habitat for nesting birds in the lowland hay meadows through specific management intervention consisting in mowing; the creation of new alluvial forests.
|Monitoring surveys and results=The results of the monitoring survey started in 2003 revealed an increase of some bird species using the restored habitats as nesting, feeding and hunting (raptors) areas as a positive consequence of the interventions, especially in the lowland hay meadows and in the dry scrublands.

|Project summary=The area of intervention is indeed a strip of territory, which for historical reasons and geographical conditions, has been relatively little used and so it was particularly intact.
For these characteristics, in this particular area have been identified seven SIC showing the particular concentration of species and habitats priority.

Unfortunately, in recent years occurred excessive use of resources and environments and abandonment and neglect of large portions of land that have caused serious degradation phenomena (pollution of water, simplification of environments, surface soil erosion, spread of exotic species,… etc.).

Particularly in view of the situation described above, the project has provided actions:
- Preliminary analysis environment, fauna and flora;
- Training courses, meetings of public awareness, production of informative material and
construction of a dedicated Web site;
- Recovery territorial Interventions (removal of exotic species, forest management, rehabilitation
of degraded habitats);
- Monitoring the quality of natural environments and the impact of works.

The main results achieved were as follows:
1. Adherence to the system of certification of forest management recognized at the level of
European forests Regional Natural Reserve of the "Selva Lamone of" Action A6;
2. Safeguard measures in the woods, Action C1;
3. Construction of infrastructure read to prevent the passage on lawns (presence of rare species
and orchids), Action C2;
4. Restoration of riparian buffer strip of River Olpeta and Lake Mezzano, Action C3;
5. Implementation of operations of wetlands along the riparian zone at the River Olpeta and Lake
Mezzano, Action C4;
6. Periodic cutting grass in areas at risk of colonization by the invasive shrubs, Action D1;
7. Implementation of operations for forest management, Action D2;
8. Maintenance network paths of Regional Natural Reserve of the Selva Lamone and Lake
Mezzano, Action D3;
9. Maintenance of riparian buffer strip at the River Olpeta and Lake Mezzano, Action D4;
10. Distribution of leaflets to the public with the involvement of schools and universities, Action
E1;
11. Distribution of brochures to the public with the involvement of schools and universities,
Action E2;
12. Allocation of sixteen boards and information boards in the most important points of SCI and
Commons, Action E5;
13. Realization of press conferences, Action E6;
14. Accomplishing a public meeting with farmers' category, Action E9
|Monitoring surveys and results=The project then has made concrete interventions naturalistic engineering and maintenance of natural forests designed to initiate a process of recovery now cannot be extended.
The actions, even if localized, will bring a significant improvement in natural environments involved, with the consequent benefit to the species of animals and plants that they also host leading to increased intrinsic biodiversity habitats and encouraging the preservation of animal and plant species included in the Directive.

Case study:Restoration of the original riverbed of the Steinbaechlein

|Project summary=The Steinbaechlein is a 14.5 kilometers long secondary arm of the Doller, the latter having a mainly agricultural 215 km2 wide watershed.
In the XIX century, a 400 long meander of the Steinbaechlein was cut in order to provide water to a chemical factory.
Following the dismantling of the factory and in the framework of a new business and residential development, the river was returned to its old bed. The work was motivated by the need to increase the available surface for a commercial building and the will to get the river away from polluted soil.
The new bed was excavated in the wasteland that had developed in place of the former course of the river. Diversified cross sections and widths were established and the profile was fixed by two sills; helophytes were planted in the banks and in the riverbed along almost all the restored stretch. On the left side of the river a wetland was created, to be used as flood retention area.
|Monitoring surveys and results=No pre-project assessment was carried out. In 2007, electrofishing was conducted by the National Office for Water and Aquatic Environments (ONEMA), showing a good recolonization of the restored stretch by fish; juveniles of trout, target species in the river, were also found. Since then no other monitoring has been done or is foreseen.

Case study:Restoration of the Bellegarde hydraulic annex and sediment recharge of the Ain River

|Project summary=The Ain river flows for 195 km from its source in the Jura Mountains to its confluence with the Rhone, upstream of Lyon. Throughout its length, it presents very rich aquatic ecosystems.
Between 1945 and 1980, the river Ain was modified: from a braided riverbed to a single channel. This change is accelerated by the development of hydroelectric plants, bank protections, dikes ... thereby reducing the intake of solid materials from upstream and banks.
Due to the deficiency of solid materials, the incision is strongly stepped. Thus, the incision causes paving of the riverbed downstream of the structures and led to the disconnection of the hydraulic annexes with the alluvial groundwater.
The lower Ain valley is included in one of the Natura 2000 site and the restoration of the hydraulic annexes of the Ain River is carried out with a Life Project.
The Bellegarde hydraulic annex (a pond) is chosen because it is located in an area with a low flow dynamic and where the river is paved. The restoration of this pond may also allow a sediment recharge of the river.
The first step is the identification of the functional parts of the pond and the parts to restore. Cleaning and milling operations are carried out on a hectare. A lowering of the bottom of the pond is also realized. The materials removed, 18 000 m3 of pebbles, are directly redeposited in the riverbed. These will be taken by the current. The 6700 m3 of fine materials are scattered on the river banks.

|Monitoring surveys and results=The rewetting of the entire pond (3.2 hectares) is effective. The reconnection with the groundwater has been rapidly produced. Due to the slow response of the different compartments, some monitoring results are still unknown.

Case study:Removal of the Cussy weir on the Maria stream

|Project summary=The Maria stream, a tributary of Dragne, is 10 Km long and presents very low anthropic alteration. Only a weir, 2 m high and 8 m wide, degrades the environment, constituting an obstacle to ecological continuity and sediment transport. It was built in 1932 to supply drinking water, but no longer used after 1951.
A restoration project was undertaken.
During the works, the river is diverted into a pipe. A straw filter is placed downstream of the structure to trap fine sediments. The work begins with the extraction of sediment upstream of the structure, placed on the sides. The weir is then destroyed and the banks stabilized with blocks, found on site.

|Monitoring surveys and results=The weir removal allows the reconnection of nine kilometers of waterways. The population composition has not changed after works: trout and sculpin remained the two species recorded. The 2004 monitoring shows a recolonization of upstream sector by trout fry. In 2009, the trout population increases and reaches its equilibrium level .
In 2004, the lotic area recreated is immediately recolonized by sculpins. In 2009, Sculpin populations decrease. The evolution of the population of sculpin deserves a monitoring programme and comparisons with nearby rivers.
The weir removal restores sediment transport. The vegetation naturally recolonize the environment and stabilize the banks.
A new weir deletion on the Dragne watershed is planned for 2011.

|Project summary=The Maria stream, a tributary of Dragne, is 10 Km long and presents very low anthropic alteration. Only a weir, 2 m high and 8 m wide, degrades the environment, constituting an obstacle to ecological continuity and sediment transport. It was built in 1932 to supply drinking water, but no longer used after 1951.
A restoration project was undertaken.
During the works, the river is diverted into a pipe. A straw filter is placed downstream of the structure to trap fine sediments. The work begins with the extraction of sediment upstream of the structure, placed on the sides. The weir is then destroyed and the banks stabilized with blocks, found on site.

|Monitoring surveys and results=The weir removal allows the reconnection of nine kilometers of waterways. The population composition has not changed after works: trout and sculpin remained the two species recorded. The 2004 monitoring shows a recolonization of upstream sector by trout fry. In 2009, the trout population increases and reaches its equilibrium level .
In 2004, the lotic area recreated is immediately recolonized by sculpins. In 2009, Sculpin populations decrease. The evolution of the population of sculpin deserves a monitoring programme and comparisons with nearby rivers.
The weir removal restores sediment transport. The vegetation naturally recolonize the environment and stabilize the banks.
A new weir deletion on the Dragne watershed is planned for 2011.

Case study:Removal of a pond weir in a tributary of Petersbach

|Project summary=The Saumuehle stream is a 1,5 Km tributary of the Petersbach river, located in the Petite Pierre Nord forest. It is a firs class fish stream.
In 1980, the Saumuehle pond (12000 m2) was created for recreational fishing. The pond cause warming waters downstream and the weir is an obstacle to ecological continuity.
After a few years, the dam, made with soil from the excavation of the pond, lost its seal and the water level had dropped, leading to a gradual filling of the pond.
Under an Interreg project which aims to improve the condition of the river in the forest, this site was chosen as a pilot site.
The work takes place in several phases. At first, the pond is drained in order to remove the drain boards
After conducting a fishing rescue and temporary diversion of the river to a side ditch, materials of the dam are moved on the edge of the pond. Then, reprofiling sloping instead of the dam is made. A lateral pond is created to hold the presence of amphibians observed on the site.
|Monitoring surveys and results=This restoration has reconnecting 1400 linear meters of stream. After draining the pond, the river quickly regained a sinuous channel. The substrate is unclogged and coarse aggregate appeared; also riffles and mouilles appeared upstream.
A post-work fishing monitoring shows clearly a recolonization of the brown trout upstream.
In 2008, during winter floods, the bed of the stream moves a few meters on the left bank, where the new pond was created. This was quickly picked up by the river. This has proven that the pond was created too early: It would have to wait until the stabilization of the river bed. This pond will be recreated when the bed is completely stabilized.

|Project summary=La Vence, 34 Km long, is a tributary of Mouse River. It was modified by the presence of eleven sluice gates, historically used to generate hydropower for artisanal or industrial uses.
Nowadays they have lost their original use (with the exception of a micro hydropower still active) and they are used only for water control during low water.
The lack of consultation during the sluices gate operations increases the flooding risk. This leads the local institutions - le syndicat intercommunal d’études et de travaux pour l’aménagement de la Vence (SIETAV) et la direction départementale de l’agriculture et de la forêt (DDAF) - to propose adjustments for each of them. Three owners agreed to try it and let the sluice gates open.
The valves are held open on two sluice gates and two of them can be removed.
Work bank protection and flow diversification are made a few hundred meters upstream and downstream each sluice gate.
Baffles, combs and dead wood is placed to diversify flows and limit bank erosion and narrowing of the the riverbed. Willow stakes are placed to recreate a riparian revegetation. This work is done in the traditional way without the use of motorized vehicles in the riverbed.

|Monitoring surveys and results=The monitoring show an increase of the habitats diversification especially in terms of flow velocity and depth. Regression for mineral substrates (clogging) in favor of more coarse mineral substrates (favorable for spawning) is observed.
