Main objective:
To empower the multi-sectoral stakeholders sharing the territory of an international river corridor to gain knowledge on river corridor management, exceeding sectoral, local and national interests in order to ensure good water status and flood protection, preserve nature, biodiversity and ecosystems, and to enable development at the same time.
Specific objectives of the project are:
To develop a joint approach (SEE River Tolkit) for integrative management of international river corridors; the Toolkit will give guidance on planning and implementing procedures for harmonisation and prioritisation of heterogeneous sectoral policies, plans and programmes related to management of international rivers.
To apply the joint approach (Toolkit) to agree on future joint actions that will ensure integrative management of the International Drava River Corridor (Drava River Action Plan); key institutions from all five Drava-riparian countries will work together to reach consensus on vision, goals and actions for future management of the international Drava River Corridor.
To work together with local, regional and national stakeholders in the five Drava-riparian countries to reach multi-sectoral agreements on concrete actions to implement the internationally agreed Drava River vision; the agreed Local Action Plans will be the basis for management of the selected river corridors on local levels.
To use and promote the Toolkit on 5 additional international river corridors for Bodrog, Neretva, Prut, Soca, and Vjosa rivers; Draft Action Plans for future cooperation in management of these rivers will be prepared by establishing transboundary stakeholder partnerships in all riparian countries.
To improve the transboundary and cross-sectoral cooperation of existing bodies responsible for managing international rivers by involving them in the process of seeking consensus on future action plans for integrative management on all 6 rivers.
To facilitate the implementation of relevant EU legislation, in particular the Water Framework Directive, the Flood Directive, the Habitat Directive, the Birds Directive and the Renewable Resources Directive.
To increase capacity and raise awareness of stakeholders along international river corridors on importance of transboundary and cross-sectoral approach to sustainable integrative management of river corridors by organising partner trainings, stakeholder workshops and capacity building seminars for addressed stakeholders.

Many measures to get this points: Dunes regeneration, elimination of plastic waste, sustainable uses of many techniques (fishing, seafood collection...), protection of intertidal space... As a result, O Grove has become in a rout of passage for many groups of birds that come from North Europe and Africa. Furthermore is a good place for the breeding of birds like Charadrius alejandrinus. +

Measure of the effects and future directions
We will monitor the respective effects of the 3 hydraulic calendars on the Mediterranean biodiversity, together with the hunting and pastoral values. The measures target the habitat (water levels, salinity), gaming and grazing activities (hunting bags, foraging value, users satisfaction…) and biodiversity (aquatic plants, dragonflies, ducks…). +

Mise à part la réalisation d’un profi l en long
effectué par la DDAF pour le calage des travaux
à réaliser, il n’y a pas eu d’état initial. Aucune
étude de suivi n’a été mise en place pour
évaluer les effets écologiques de l’opération.
Après les travaux, le service départemental de
l’Onema a constaté une reprise de la circulation
des sédiments auparavant bloqués par la
retenue. De même, l’érosion semble stabilisée
en aval de l’ancien seuil. Les crues biennales
hivernales successives retracent rapidement
la morphologie du cours d’eau (alternance de
dépôts et de zones d’érosion). L’effacement
de l’ouvrage a permis la réapparition d’une
diversité d’habitats en amont de l’ouvrage: diversité des écoulements, hétérogénéité
granulométrique et diversité des profi ls en
travers. Une surface importante pour la fraie
des espèces piscicoles est ainsi restaurée.
Sur sa partie aval, le Céans a retrouvé une
continuité hydraulique (assecs estivaux restreints),
du fait de l’arrêt du prélèvement
d’eau. Le cours d’eau retrouve également
une continuité piscicole jusqu’au prochain
ouvrage situé 6 km en amont.
Cependant, l’absence de suivi scientifi que ne
permet pas de mesurer la réappropriation du
linéaire par la faune aquatique.
Les acteurs locaux estiment que la réalisation
de cette opération est pleinement satisfaisante. Elle s’est déroulée selon les objectifs
fi xés au départ, à savoir concilier les usages
économiques du secteur – activité agricole
avec prélèvements d’eau – et les enjeux écologiques
– respect du débit minimum, circulation
des poissons et du transit sédimentaire.
La réussite de cette action a conduit le Syndicat
mixte de gestion intercommunautaire
du Buëch et de ses affluents (SMIGIBA),
structure possédant la compétence eau sur
le secteur, à travailler sur un projet d’arasement
de 6 seuils successifs sur la Blaisance,
rivière voisine, dans le cadre du contrat de
rivière Buëch et affluents. Ces seuils sont
en partie infranchissables et ont perdu leur
usage initial. La stratégie adoptée par le
syndicat est le décloisonnement progressif
du cours d’eau par réouverture de tronçons
de cours d’eau.

Monitor changes in pearl mussel and salmonid populations. Pearl mussels are very slow-growing. It is not expected that statistically significant increases in pearl mussel populations will be seen during the short life-time of this project. However, a number of 'proxy' measures will be used to ascertain whether conditions have improved for pearl mussels. Some baseline monitoring of mussel populations will take place, to ensure that meaningful comparisons can be made with data gathered in the future and to ensure that actions are properly targeted. Salmonids are much shorter-lived and their numbers can be expected to respond much more quickly to improvements in habitat conditions. Monitoring of freshwater pearl mussel and salmonid populations will take place prior to the implementation of the conservation actions. Repeat monitoring of salmonid populations will take place after the conservation actions to establish the extent of improvement. +
Monitor water quality, habitat restoration, pearl mussel populations and host salmonids +

Monitoring and evaluation is fundamental to all the activities, to help evaluate impact as well as inform future work. The evidence collected includes fixed point photography, invertebrate and species surveys, water quality monitoring, recording of landowner engagement and volunteer activity.
A programme of fixed point photography has been carried out across key restoration sites, capturing seasonal changes and fluctuations in water levels. These images clearly show how restored river habitats establish and evolve over time, and they provide valuable material to share with farmers and other stakeholders.
Surveys for freshwater aquatic invertebrates at key sites have been able to show how the river is starting to recover, once river restoration has been completed.
Phosphate monitoring at intervention sites and on all the major tributaries has helped to evaluate schemes, as well as inform the future targeting of work, including the nutrient neutrality framework.
Engagement has been a key focus. We maintain an engagement tracker which helps to strengthen our understanding of landowner and communities’ interests in the methods used.
Specific species surveys have been undertaken including White clawed-crayfish, fish and INNS.
The evidence is assessed on a regular basis to report the impact, influence future work and raise awareness of achievements. +

Monitoring and evaluation support the project through targeted electrofishing surveys and wider ecological monitoring. As the programme moves from delivery to optimisation, the installation of fish counters represents a key next step, providing robust, quantitative evidence of fish passage effectiveness and demonstrating restored connectivity at a catchment scale. This enhanced monitoring will help secure the long-term legacy of the project and inform best practice for migratory fish restoration elsewhere. +

Monitoring and evaluation was embedded from the outset, designed around the aims of the National Lottery Heritage Fund funding programme, looking at outputs – counting deliverables, and outcomes – the change we have made as a result of our work. Outcomes for people were demonstrated through individual testimonials, commentary or feedback throughout the programme. For our river improvement projects, more detailed monitoring and assessment was carried out through a series of case study sites illustrating different types of projects and the positive impact that these projects can have on our environment. Methods included temperature logging, fish radio tagging and mark and recapture studies, soil compaction, flow measurements and food web analysis.
The people focussed evaluation was carried out internally, with a mixture of citizen science, professional or academic investigation, as well as the project team for our river projects. Where possible we tried to be innovative and creative, integrating our evaluation with the engagement work we carried out to raise awareness and involve people in our delivery.
Long term impact will be measured through our annual electro-fishing monitoring programme, as well as return monitoring and maintenance visits and an expanded citizen science programme, which is a key legacy of this programme. +
Monitoring assessed the physical and biological conditions of the river and estuary, as well as the social attitudes to the river over the life of the project. The project successfully demonstrated a range of interventions to raise awareness of the river and mobilise interest in mitigation projects in the local community. Further information on this and other aspects on the project can be retrieved from the project website (see above and references). +

Monitoring consists of invertebrate surveys, electro-fish surveys and fixed-point photography. Data was collected throughout 2013 and 2014 through volunteer effort. Results have yet to be analysed. +
R
Monitoring has included water quality testing, macroinvertebrate sampling, fixed point photography, questionnaires and ecological surveys. See individual entries for more details. +

Monitoring is multimethod and repeatable, designed to measure habitat change, species response and connectivity. Core elements are: annual electrofishing at six historic EA sites to track species composition, abundance, biomass and age structure; eDNA sampling for early detection of low‑density or cryptic species; redd counts each autumn/winter to map salmon spawning distribution; fixed‑point photography and drone surveys to document geomorphic evolution; trail cameras to record wildlife use; and UKHab assessments to classify habitat condition.
Additional techniques included non‑EA electric fishing surveys, repeat visits to assess rust‑fungus biocontrol trials for invasive plants, and hydraulic/flow modelling used both in design and post‑event evaluation.
These complementary methods provide quantitative and qualitative lines of evidence for adaptive management and are repeated on a defined schedule to allow before/after and upstream/downstream comparisons.
Results:
The project reopened previously inaccessible habitat and produced clear biological responses: salmon recolonised upstream reaches within months of Snake Lane works (a spawned‑out hen found 1 km upstream), and by 2025 an Atlantic salmon parr plus several newly recorded coarse fish species were documented at Postern Mill, confirming reconnection. Electrofishing and eDNA confirm return and movement of species including Atlantic salmon, chub, grayling and gudgeon.
Morphological monitoring shows active sediment transport, evolving riffles, pools and meanders; trail cameras and public reporting demonstrate increased wildlife use and strong community interest. The scheme gained national/international attention (Dam Removal Europe finalist; Natural History Museum case study). +

Monitoring is quite problematic, since the stream runs dry for about 3 to 4 months a year. +
C
Monitoring of aquatic vegetation, especially during the prolonged drought that central Texas has been experiencing, is important to understanding potential impacts to fountain darters. Bryophytes (mosses) hold high densities of fountain darters and can be abundant in select locations of the Comal system (e.g., Upper Spring Run upstream of Landa Lake and in the upper portion of Landa Lake). Bryophyte stands in Landa Lake remained relatively constant between 2011-2012 (Figure 2). Cabomba, another native plant with relatively high densities of fountain darters, has been increasing in coverage in Landa Lake, and by fall 2012 it had the highest coverage that has been observed over the course of the study (Figure 2). In contrast, the aquatic vegetation in the Old Channel exemplifies the interactions between native (''Lugwigia'') and non-native (''Hygrophila'') aquatic vegetation in the river. Over the past several years, Ludwigia has become sparse (filamentous algae is rarely present), while Hygrophila has come to dominate most of the reach (Figure 3). ''Hygrophila'' flourishes in the Old Channel, and has been crowding out native ''Ludwigia'' (which has higher fountain darter densities) over the last several years. Ludwigia declined over the course of 2012 and is near the lowest coverage observed over the past decade. Bryophytes significantly increased in coverage during 2012, a ten-fold increase to the highest coverage ever observed at the Old Channel Reach. Since high densities of fountain darters occupy bryophytes in the Comal River, this could mean increased populations of the endangered fish if bryophytes remain in the Old Channel Reach. Filamentous algae, which covered a significant portion of this reach in the past, were still absent from the reach in 2012. +

Monitoring of fish, bed fauna, physical conditions of the watercourse and birds has been conducted before the project start to ensure there is background registrations available to compare with the monitoring after the project start that will take place in 2014. Nitrogen levels and habitat types are also to be monitored
Expected results: (1) New wetlands of 350 hectares, (2) reduction of nitrogen load to Odense Fjord of approx. 60 tonnes of nitrogen a year, a (3) re-meandered watercourse stretch of approx. 10 km of the Tiver Odense, (4) grazing agreements for 156 hectares along the river, (5) grazing agreements for approx. 51 hectares along the fjord, (6) management plans for coastal meadows along the fjord and management plans for areas along the river, (7) improvements in relation to favourable conservation status for Habitat species and Habitat nature types, (8) information boards, (9) observation tower for the public. +
