The monitoring of biodiversity components is conducted according to the criteria of SEBI 2010 （Streamlining European 2010 Biodiversity Indicators） for establishment of consistency at global, regional, EU and national indicator level. Two core segments of the Biodiversity Strategy and Action Plan of Republic of Macedonia are presented as well as the draft list of biodiversity indicators. Ecosystems and biotopes （presented with plant communities） are explained from which 30 Corine habitat classes are identified for the Republic of Macedonia. The number of endemic and endangered species from different taxonomic groups of vascular plants, fungi, fauna, and Emerald species with European importance are presented. Agro-biodiversity, structure of agriculture land, autochthonic breeds of domestic animals as well as the network of protected areas in Republic of Macedonia are presented. At the end conclusion remarks are given for future necessary activities at national and international level regarding monitoring and conservation of the biodiversity.展开更多
