The purpose of the study is to determine how the population of the ruff in Sweden has changed over the past 20 years and which reasons for the changes, if any, there are. The study also includes how the tourism regarding the ruff in Sweden is today and how it could be developed. The study is based on non-fiction literature, reports, diagrams and interviews. The population of the ruff in Europe has declined over the past years. In Sweden, the breed is classified as vulnerable on the IUCN Red list of threatened species due to the fast decline. The results show that the population of the ruff has changed in the whole country of Sweden. Today almost 99% of the population lives on tundra and wetlands in northern Sweden. Most of the decline has occurred in the south of Sweden where the population almost is extinct. In northern Sweden, the population also has declined but not as much as in the south. Nowadays the ruff only breeds in 8 out of 22 counties it used to occur in. Reasons of the decline are primarily changes in habitats, drainage of watercourses and wetlands, urbanization, agriculture and forestry. The decline also depends on changes along the migration routes and in northwest Africa where the breed winters. Also, climate change and higher predation are reasons for the decline. No tourism with focus on the ruff exists in Sweden today. There is a potential in developing a specific tourism focused on the ruff lek.
