Background Peat-bog ecosystems are very important for European biodiversity. Even bogs that were once used for peat excavation can, after natural or human-initiated recovery, become valuable wetlands, containing a wide range of specific ecosystems. In Lithuania, the natural re-flooding of former peat extraction sites and the growth of patches of sedge-grass attract breeding spotted crake and migratory common crane. However, overgrowth with bushes and reeds disrupts the water regime and has a negative impact on the condition of the habitat. Objectives The main objective of the Tyruliai - Life project is to ensure the favourable conservation status of bittern (Botaurus stellaris) – listed on the Annex I of the Birds Directive – and the breeding bird species, spotted crake (Porzana porzana) and migratory common crane (Grus grus). The target area is the Tyruliai bog, a State nature zoological-botanical reserve and a Natura 2000 site. The conservation of these species will be achieved by: Improving the condition of their habitats and increasing their capacity; Restoring the hydrological regime in some areas of the Natura 2000 site; Supporting natural succession of the sedge-grass communities; Reducing disturbance to birds; Maintaining an existing fire prevention scheme; Raising public awareness about the benefits of bog restoration. Expected results: The main excepted result is an increase in the breeding population of bittern, by at least 20 pairs, spotted crake, by up to 30 males, and staging cranes, by more than 1000 individuals. These results will be accompanied by the following habitat management measures: Re-wetting of more than 500 ha of dry peat; Improved capacity of at least 200 ha of former open sedge-grass areas and more than 100 ha of dense reed stands overgrowing wet peatland areas; Improved capacity of more than 200 ha of reed stands growing in the flooded ponds, by the removal of reeds on at least 20 ha; Elimination of car traffic from a large part (1000 ha) of the reserve through the closure of local roads. At the same time, the quality of these roads will be improved to ensure effective fire prevention; Greater public awareness about the project actions and the benefits of bog restoration.
