Restoration of active raised bog - Lille Vildmose

Reference: LIFE10 NAT/DK/000102 | Acronym: Lille Vildmose

PROJECT DESCRIPTION

BACKGROUND

Active raised bogs are a priority habitat for conservation and are included in Annex I of the Habitats Directive. This habitat has suffered a steep decline in Europe in recent years. In Lille Vildmose (and in Denmark overall) active raised bogs have an unfavourable conservation status. This is mainly due to drainage, the invasion of trees, in particular birch, and deposition of airborne nitrogen from agricultural use and long-distance transport.


OBJECTIVES

The objective of the Lille Vildmose project was to restore the largest remaining raised bog in lowland northwest Europe, Lille Vildmose in Denmark. The project aimed to improve the conservation status of this priority habitat by facilitating re-growth of sphagnum moss and raising the water table in areas of degraded raised bogs or in areas where peat has been excavated. These actions will result in a significant enlargement of the habitat area. Other wetland habitat types, such as natural dystrophic lakes and ponds, transition mires, and quaking bogs will also increase in size and number. Bog woodland coverage will decrease in areas selected for active raised bog restoration but will increase in other areas thanks to restoration ? many areas have until recently been used for peat extraction.


RESULTS

The Lille Vildmose project achieved all its objectives to protect and improve the Lille Vildmose active raised bog in Denmark, by enhancing ecological coherence and connectivity. This resulted in the improvement of the conservation status of the entire Nature 2000 site. Most of the effects of the projects measures are expected to unfold over many years, as the raised bogs habitats gradually respond to the restored hydrological system. However, in many areas the response has been immediate and is already visible.

Significant improvements in hydrological conditions have occurred, particularly in the impacted edge areas where active raised bog borders farmland. The large-scale clearance of tree growth and the introduction of grazing by large herbivores is expected to significantly improve the conservation status of 2 100 ha, mapped as the habitat type Active raised bogs (7110*), which was in unfavourable conservation status mainly due to birch invasion and desiccation. The projects actions also restored and improved other habitat types in Annex I of the Habitats Directive: Degraded raised bogs still capable of natural regeneration (7120), as well as Natural dystrophic lakes and ponds (3160), Transition mires and quaking bogs (7140) and Bog woodland (91D0*) on more than 900 ha.

Due to the significantly enlarged wetland areas, combined with a predator-control programme for securing breeding sites for ground-nesting birds, living conditions for the Annex I species black stork, wood sandpiper, hen harrier, white-tailed eagle, crane, and short-eared owl have been improved. However, due to initial low national population sizes, it will take more time to see significant results. Furthermore, the predator-control actions have revealed that even with a large effort, especially for racoon dog, populations still seem to increase. This trend is also seen in the rest of the country and in neighbouring countries. Several rare moth and butterfly species occur in the central parts of the raised bog areas, including two with their only Danish occurrence here (Orgyia recens and Idaea pallidata).

Today, the overall Natura 2000 site is one of the largest and most coherent natural area in Denmark, with unique opportunities to experience large areas of a unique type of natural wetland.
