||Public use of protected areas is changing, with declines in activities such as horse riding and hunting in some locations, while others such as mountain bike riding are increasing. Mountain biking riding is popular now in a wide range of protected areas from urban parks to wilderness areas and in many countries. Such popularity energizes the discourse about how mountain biking can contribute to protected area objectives, and at what cost. There is also an increasing focus on research on social and environmental aspects of mountain biking. This interest was reflected in numerous talks on the challenges of managing and monitoring mountain biking at MMV7 (Reimann et al. 2014). Inspired by this emphasis, a special issue of the Journal of Outdoor Recreation and Tourism was set aside to showcase the latest research on mountain biking (Pickering and Leung, 2016).
