Kozjansko Park is one of the oldest and largest protected areas in Slovenia. It is located in the east of Slovenia and covers an area of 206 km2. It has the status of a regional park. It covers an area that is bounded on the north by Rudnica, to the east with Sotlo, while in the south via Vertnik and Orlica it passes over Senovo and Bizeljski hills.
The larger, especially the middle and eastern part of the Kozjansko Park, the Republic of Slovenia in 1981, declared by the Law a protected area of the Memorial Park Trebča. Because of the professional, systematic and promotional reasons, the park was increasingly called Kozjansko Park, and in 1999 with the adoption of the Law on Protection of Nature it was declared a regional park and officially renamed to Kozjansko Park. The high degree of biological diversity classifies Kozjansko Park among the most important protected areas in Slovenia and Europe. From 2010, Kozjansko and Obsotelje area enjoy the status of a biosphere reserve under the UNESCO protection (MAB Programe - Man and the Biosphere).
The protected area with the status of the regional park is a mosaic of subalpine hills, vineyard hills, plains along the river Sutla, preserved nature and rich cultural heritage which offers a lot of opportunities to explore, enjoy and relax. The nature of Kozjansko Park is known for its rich biodiversity, which is testified by the fact that even 69% of Kozjansko Regional Park belongs to the area of Natura 2000.
Among the flora of this area, the plant species on the Red List deserve special attention. In the area of Kozjansko Park there are more than 70 species, which according to the Decree on placing of endangered plant and animal species (Official Gazette No. 82/02) belonging to the Red List.
Fauna, with the exception of birds, amphibians and certain kinds of insects has not yet been explored sufficiently in the area of Kozjansko Park. The diversity of relatively well preserved habitats also affects biodiversity. The traditional use of pastures is essential for the number of species of insects and spiders. Some of them are rare and endangered species in Slovenia, and even in Europe. Unfortunately, these habitats gradually disappear.
Since pure water habitats are increasingly becoming a rarity, the wealth of the region, is reflected also in the preserved water surfaces. Unpolluted streams Bistrica, Dramlja, Gabrnica are the natural habitats for some endangered species that survive only in clean water systems.
The geological structure of the area is also interesting. The oldest rocks in this area are about 300 million years old, dating from the time when this area was under the sea. So far the fossil remains haven’t been found in them.
Kozjansko Apple Festival is a traditional central event in the Park, which is held every year in the second week of October from 2000. This event is a product of collaborative effort between residents of this protected area of biosphere and joint efforts for the protection of nature and preservation of agricultural and cultural environment in the Kozjansko region. The greatest characteristics are the preserved orchards with tall trees of old varieties of apples.
