Based on the conducted research, it is obvious that the Environmental Protection and Energy Efficiency Fund of the Republic of Croatia recognised the importance of protection of indigenous, Croatian breeds and protected animal and plant species in the Republic of Croatia, which is corroborated by support for the project entitled the Hrvatica hen –in the Dalmatian Hinterland. The Hrvatica hen breeding programme in the Dalmatian Hinterland shows consistency (confirmed in the interview) in accordance with all the relevant prescribed principles. The existing cooperation of all entities in the preparation and implementation of action measures, as well as in providing financial support, and stimulating the public to preserve and promote the breed at national and international level is shown. Breeding of the Hrvatica hen in the previous period has been on a constant increase, both in terms of the number of breeders and the number of breeding hens. The results of the survey Buying eco-products (included 50 respondents from each large town respectively: Zagreb, Rijeka, Osijek, and Split) show that people are aware of the importance of protection of indigenous animals and plants, and of breeding indigenous breeds in Croatia, that buyers prefer domestically grown ecological products on which they are willing to spend more money, and that there is a demand for ecologically grown food products. Buying of domestic eco-products strengthens and supports Croatian producers, and increases the consumers’ trust in the domestic producers. A good example for the future breeders is provided by the Homeland War veterans Cooperative Pauk-Čeka. It provides an exemplary model of breeding of the Hrvatica hen which meets all the criteria. Breeding of the indigenous Hrvatica hen breed ensures the sustainability of the ecosystem, it provides for the sustainability of rural areas, and ensures continued existence of small holdings.
