Résumé
Summary
The measure was implemented in 2013 in Matsalu National Park (Natura 2000, Ramsar), at a former coastal meadow beside the large Salmi complex. Old, non-functioning field ditches were closed and scraped to restore wetland hydrology and breeding/feeding habitat for waders and amphibians. Grazing continued as before, with better access to drinking water for cattle.
Since then, the site has been managed as part of the wider Keemu–Salmi coastal meadow system (~360 ha) within a park that maintains ~3,000 ha of coastal meadows, among the largest in Europe. National guidance and the 2021–2027 Action Plan for semi-natural grasslands reinforce long-term maintenance (grazing/mowing, shrub control) and allow restoration actions such as closing drainage to keep meadows wet.
For fauna, Salmi–Keemu is a priority area for the natterjack toad; the species plan recommends sustaining sufficient grazing to keep short-sward habitat and preserving shallow, temporary pools created by micro-relief. In response to very high nest predation on coastal meadows, a pilot predator-control programme (2021–2024) was introduced at Keemu and Salmi to improve wader breeding outcomes.
Overall, the 2013 hydrological works are now embedded in park- and nation-wide management that keeps the meadows open and wet while targeting key bird and amphibian conservation needs.
The project was a rather small-scale restoration effort, which was originally intended to be expanded, but for various reasons this did not take place. No monitoring activities have been carried out to assess the effectiveness of the restoration.

Location of the project
Salmi coastal meadow in western Estonia in Matsalu National Park (southern shore of Matsalu bay), rural coastal area, Natura 2000 and Ramsar site. The area of the Salmi coastal meadow is approximately 350 ha which makes it one of the largest complete coastal meadow massifs in whole Europe.

Wetland restoration and management
Objectives
Restore the hydrological regime by closing and scraping old field ditches to slow drainage from the meadow to the sea; this was the primary design target (“regulation of hydrological cycle and water flow”).
Recreate breeding/feeding habitat for waders and amphibians (and other protected species)
Keep existing bovine grazing unchanged while improving access to drinking water for cattle as a co-benefit.
Pilot/validate a restoration method (inspired by UK practice) for potential replication on other Estonian coastal meadows affected by old drainage.
Ditches treated: 12 small ditches, totaling ~3.9 km of ditch network closed/scraped.

Principles
The aim of the application was to test in Estonia a new methodology for restoring a wetland (based on the example from United Kingdom) and to find out if this methodology can be used also for other similar areas with similar problems (old ditches that change hydrological conditions in nature protection areas).
Factor constraints
The method for restoring the wetland was chosen for testing by Estonian Fund for nature and it was done in frame of a project.
However, it was quite difficult to find common ground with
Environmental Board, Agricultural Board and State Forestry - Estonian Fund for Nature had two years of meetings with them before they could manage to complete the project.

Financing
Total cost information
Part of the costs were covered by WWF project - ca 11 500 eur - some parctical works and costs for meetings and travel. However, part of the costruction costs were paid by State Forest Management Centre in frame of one frame project so costs are not available.

Policy and Governance
Policy description
There are some species that depend directly on the water level of the coastal meadow. In the project area there were old ditches that caused the situation that water in the coastal meadow flew quickly to ditches and from there directly to the sea. Even though a lot of the ditches were by now filled with grass and did not direct water that quickly, they were still surprisingly deep and acted as drainage for the coastal meadow – water was collected in the ditches and stayed there and surrounding areas were dry. The aim was to close and scrape the ditches and in that way restore the natural hydrological regime of the coastal meadow and via that provide suitable habitat to different (incl. protected) species.

Policy challenges requirements
Estonian Nature Protection Act aims to protect the natural environment by promoting the preservation of biodiversity through ensuring the natural habitats and the populations of species of wild fauna, flora and fungi at a favourable conservation status.
In the Estonian Environmental Strategy 2030 under the topic preservation of the diversity of landscapes and biodiversity there is and objective to ensure the existence of habitats and biotic communities necessary for the preservation of viable populations of species.

Monitoring System
Monitoring requirements
As the works were finalised in 2013 then monitoring has not yet been possible. 2014 there is a plan to monitor the dams and see if they need improvement and after 5 years to see if the area is being used by birds and amphibians.

Impact Assessment Methodology
Performance impact assessment method
Catchment outlet
Performance impact estimation information
The effectiveness of the measure depends on the habitat -if the species formerly identified in the coastal meadow (before the land improvement activities in the past) - so methodology will be counting the habitats
Socio-economic Impacts
Direct benefits information
Effective implementation of the measure will restore the habitat of the coastal meadow and will thus add to implementing the Nature Protection Act and Estonian Environmental Strategy 2030. As a Natura2000 and Ramsar site the restoration activity also contributes to their requirements.
Predator control required coordination with local hunters; in the pilot, hunter associations received a modest €1,000/season stipend, useful for planning long-term budgeting/replicability.
The site remains embedded in a park-wide managed meadow network (~3,000 ha), which concentrates grazing and visitor interest (Keemu tower area), strengthening legitimacy and continuity of management.

Information on improved biodiversity
The species ( rare species - Platanthera bifolia, Dactylorhiza incarnata). At the moment in ditches - Lythrum salicaria, Carex vulpina, Schoenoplectus lacustris, Mentha aquatica, Alisma plantagoaquatica, Sparganium emersum.) ave formerly (before the land improvement works) been living in the area so restoration works provided possibility to for suitable habitat conditions for the species. Hoowever, monitoring is needed to confirm if the species have returned.
Restoring wetland by closing old ditches that drained the area made it unfavorable for some protected species.
Coastal-meadow ponds at Salmi/Keemu are actively used by amphibians (egg masses recorded) and by feeding waders; camera work in 2015–2016 identified main nest predators as fox and corvids, with jackal and raccoon dog occasional.
Annual wader monitoring under LIFE Integrated “Loodusrikas Eesti” links hatching success tracking to restoration and predator control; in 2024/25, 44 foxes and 43 raccoon dogs were removed across sites to reduce predation pressure.

Lessons Learned
Key lessons
Reaching common ground with different stakeholders is a time consuming process and need moderation in order to come to agreements satisfying all involved parties.
Hydrology restoration alone was necessary but not sufficient; predation is a key limiting factor for wader productivity on coastal meadows, so pair ditch-blocking + grazing with targeted predator management (timing, dens). Keep short sward and ephemeral pools for natterjack toad and waders. Embed projects within park/national plans for continuity and permissions.

Transferability
The method can be used in future in many coastal areas formerly ditched in Estonia -there are cases where it is also listed in the management plan of this kind of action
Basin characteristics influence
The effectiveness of the measure depends on the habitat -if the species formerly identified in the coastal meadow (before the land improvement activities in the past) will return to the area.
