Due to the growing negative anthropogenic impact on ecosystems, new strategies are needed to preserve them. Ecosystem services are a relatively new concept and the first concrete steps towards their implementation were made in 1977. The process of assessing ecosystem services itself is very complex due to the extent and complexity of natural ecosystem and the still insufficient amount od df field data. One of the ways of classifying ecosystem services that has been applied in Croatia is the classification into three basic types: supply, regulation, cultural. The goal of ecosystem services is to map and better analyse the state of ecosystems, assess the economic value of ecosystem, encourage various scientific disciplines to cooperate in order to preserve ecosystem services, improve ecosystems and their services and raise knowledge about nature protection and ecosystem services. The current strategy and action plan for nature protection of the Republic of Croatia for the period from 2017 to 2025 emphasizes that mapping ecosystem services is extremely important.
