The protection of rare and endangered species and habitats is an important part of Danish and EU legislation.  Due to extraction of peat, drainage and eutrophication, the bog in the 240 ha Sølsted Moor has partly dried out and has been grown over with willow and birch. At the same time, the Weatherfish, which lives in drainage channels and small water courses though the bog, is on the verge of extinction in the area, which is its only known Danish place of occurrence.  The long-term objective for Sølsted Moor is to fulfil the Natura 2000 plan for the recovery of the habitat type "active raised bog" and secure it as a favourable living place for the Weatherfish.

Therefore, Tønder Municipality in South Jutland has together with EU Life Nature (LIFE 10 NAT/DK/000099 ) prepared a project, designed to restore the formerly active raised bog in Sølsted Moor. The restoration project should at the same reshape the open structure of the bog, rise the water level and improve the drainage system and water courses as a living place for the Weatherfish.

Ramboll was selected to conduct detailed design, tendering and supervision of the restoration work, which entails detailed design, tendering and supervision of restoration of the 240 ha degraded raised bog.

Phase I consisted of clearing unwanted growth of willow, birch and alder, and collecting information about the amount of material left, trace depth from machinery, size of tree stumps, amount of regrowth, etc. by two different methods of clearing.

In Phase II, this information was subsequently used for choosing methods of clearing of a larger area. In Phase II Ramboll has also carried out a detailed hydrological project, securing a higher water level, and at the same time creating a system of interconnected channels securing favourable conditions for the Weatherfish. Later on, inoculation of sphagnum mosses will be carried out to facilitate natural growth of the bog.

The project is supported by EU through LIFE+ Nature, a financial instrument that supports projects aiming at the protection and restoration of Natura 2000 areas.
