Protected areas, due to their specificity of "products" or experiences they offer and the reasons for which they are established, apply marketing based on the principles of sustainability. For the first time in history, when man realized that a certain part of the country should be protected because he is a threat, protected areas have been established. The first such protection was established in the United States in the state of Montana. As in the world, so in the Republic of Croatia, the first serious conservative thoughts appeared in the second half of the 19th century. To enable a more comfortable and safe life, a person is ready to do everything and nothing bothers him on the way. Industrial, technological, and economic progress is the only thing that interests man. For this reason, raising awareness of the anthropogenic impact, changing life habits, and establishing protected areas are the only solutions against global pollution and habitat destruction. Therefore, the management of protected areas and ecological network areas implies the implementation of a series of measures and activities necessary for the long-term preservation of natural and other values of the area. Also, marketing that promotes such areas is green, and in addition to all the basic functions of marketing, nature is always in focus.
