Searching for an economic reason for its protection can be an argument to prevent its extinction. The purpose of this paper is to reveal the identification services provided by hamsters in the agricultural ecosystem and the determination of their correlation with human welfare. We propose the methods that can be applied for this purpose, and we check if the knowledge of the species is sufficient in order to use available methods for estimating the value of the services. The common hamster is a Citation: H˛edrzak,M.J.; Badach, E.; provider of supporting, regulating, and cultural services. Estimating their value is difficult because Korna´s,S.A. Preliminary (1) available knowledge on the species’ ecology requires an update, in many aspects, due to changes Assumptions for Identification of the to agricultural practices that have taken place since the 1970s (e.g., assessment of actual losses to Common Hamster (Cricetus cricetus) cereal, vegetable, or root crops), and also extending by context, enabling the economic valuation of as a Service Provider in the services (e.g., determination of impact range on various habitat components); it is also necessary to Agricultural Ecosystem.
