||The Covid-19 outbreak has brought about radical changes for societies, individuals as well as the environment. Concerns about the infection and strategies to deal with it, including restrictions on travel and social interaction, have dramatically altered many peoples lives. This includes also recreation in the outdoors as well as environmental impacts, following from crowding, pollution and greenhouse gas emissions. Considering the unique situation following the Covid-19 outbreak, it is of interest to study how outdoor recreation has changed and reflect upon possible environmental effects these changes may bring. We do this by asking the following questions; 1. Has participation in outdoor sports changed during the pandemic and why? 2. How has participation changed with respect to; transport and mobility, use of land and water, use of material and equipment, involvement in events, social values, motivation and meaning? 3. What are the potential environmental consequences, and opportunities, following the pan- demic? The study focuses on outdoor recreation participation in Sweden during the first months of the pandemic.
