MERLIN restoration case studies assessment
Biodiversity
The figure illustrates the length of free-flowing river where connectivity has been increased laterally (e.g. removal of artificially high channel sides to reconnect floodplain) or horizontally (e.g. the length of upstream river re-connected through removal of a barrier across the river).
This indicator is only relevant to the MERLIN river restoration case-studies, with some case studies indicating the impact of measures at demonstration sites pre-MERLIN. (CS1 — Kvorning peatland, Denmark, CS2 — Deba River, Spain, CS7b — Danube floodplain, Hungary, CS11 Emscher catchment, Germany, CS16 — Upper Scheldt catchment, Belgium).

The figure illustrates the area of re-connected floodplain (in hectares) where lateral connectivity of a river with its' floodplain has been restored to allow more natural flood management (e.g. removal of artificially high channel sides to reconnect floodplain).
This indicator is only relevant to the MERLIN river restoration case-studies, with some case studies indicating the impact of measures at demonstration sites pre-MERLIN. (CS 5 — Kampinos wetlands, Poland, CS7b — Danube floodplain, Hungary, CS9 — River Tisza, Hungary, CS11 Emscher catchment, Germany, CS13 — Sorraia floodplain, Portugal).

Flooding
Rewetting of peatland took place based on construction of a hydrotechnical device at the Łasica channel in 2017. As shown by the figure, as result of the implementation 222 ha of wetland were rewetted.
The figure shows the changes in storage capacity around the implementation of rewetting of peatland based on construction of a hydrotechnical device at the Łasica channel in 2017. Before the rewetting changes in storage capacity ranged from 0 m3 to 400000 m3, but after the implementation they ranged from 1000000 m3 to 1100000 m3.

Inclusivity — MERLIN Year 1
The figure shows the number of visitors to the MERLIN website(s) describing the respective restoration measures for the MERLIN case studies (CS1 — Kvorning, Denmark, CS14 — Komppasuo peat extraction area, Finland, CS16 — Upper Scheldt catchment, Belgium, CS7a — Danube floodplain Austria, CS12 — Lima catchment, Portugal).
The figure also shows of the number of visitors to each case study webpage from Google Analytics for the first MERLIN year.

The figure indicates a count of different types of stakeholders in case study boards (public administration, industry sector representatives, NGOs, local residents, etc.). The higher the counts the more diverse and inclusive the representation for the case-study. (CS5 — Kampinos wetlands, Poland, CS7a — Danube floodplain Austria, CS12 — Lima catchment, Portugal, CS14 — Komppasuo peat extraction area, Finland, CS16 — Upper Scheldt catchment, Belgium).
The figure shows the total number of participants attending information sessions about the restoration measures for selected case studies of the MERLIN project (CS1 — Kvorning, Denmark, CS2 — Deba river restoration, Spain, CS12 — Lima catchment, Portugal, CS14 — Komppasuo peat extraction area, Finland, CS16 — Upper Scheldt catchment, Belgium).
