Conservation of biodiversity, ecological functions and general values of Medvednica Nature Park´s grasslands

Grasslands stretch mainly along the edge parts of Medvednica Nature Park, where numerous ecotones are formed in contact with forest edges and shrubs vegetation. Although covering only 1.81% of the Park's surface, they contribute significantly to the landscape diversity and are important as habitats of many species that are relevant for protection. The aim of the first research was to determine the grassland types and their degree of overgrown within the Park. The survey was carried out in 2010 on a total of 49 localities, including the vegetation images production using the standard Braun-Blanquet method, as well as data on exposure, incline and habitat utilization. The results identified four basic grassland groups and so-called high green, and within each group two communities and several of their succession stages can be distinguished. By abandoning the villages and traditional use of space such as grazing and mowing, the development of successive vegetation of woody and bushy species has begun to change habitats. The most valuable and most endangered is the thermophilic dry grassland type with upright bromegrass in the wider Čučerje area as the only remaining finding site of Anemone Sylvestris species in Croatia. Because all of this, the employees of the Public Institution have regularly visited and evaluated the condition of flora and grassland habitats in recent years. Further research and introduction of flora and other components monitoring is essential for effective grassland management planning and the introduction of active management measures.
