The quality of the water in the Adriatic is very well preserved. The results reached through the constant measuring of the quality of water on more than 800 beaches are in accordance with the strictest criteria. Except for the cleanliness of the sea, another important quality of the coastal area is its biological and geographical particular quality, which can be seen in the number of species of plants and animals, and in the high number of endemic species (for example human fish). In order to protect and preserve such natural wealth, a list of rare and endangered species, the so called Red Book, has been made.
Various projects are carried out in Croatia by government institutions or associations of citizens with the goal of preserving natural and cultural heritage, and its evaluation. One of these projects is The Blue Flag Project, and from the year 2001, the project Green Key also starts with the goal of improving the quality of surroundings in hotels, motels, camps and other facilities. Another project is Eco habitat Green Laguna in Porec, where the environment is especially taken care of. Green Laguna has its olive groves, orchards, horse stables etc. where tourists can take active part in preserving the environment.
Through the year several days are especially marked in Croatia such as International day for water preservation, World meteorological day, Day of the planet earth, Day of the dolphins, World day of preserving the environment, Day of the Sun. Except for the natural, great significance lies on the preservation of cultural heritage, as well. National costumes and customs are preserved. During the summer, in most coastal towns special celebrations are organized in order to show tourists our local traditions, for example, traditional donkey race which is held each year in Tribunje, Moreska - knightsO dance on KorculaÉ
Croatia is also, except for its ecological cleanliness of air and water, an exceptionally safe place where everybody feels pleasant and welcome.
