These activities/indicators have been further developed in the sports and exercise surveys in 1998 and 2007 at the Danish Institute for Sports Studies (Pil-gaard 2008, 2009). Beside numerous information in relation to specific sport activities, a number of indicators/questions relevant in a forest/leisure context are included, e.g.: Bicycling in nature areas, hiking in nature areas, hiking in urban parks, the importance of nature for sport and exercise and the influence of [easy) access to nature areas on sport and exercise activities. As mentioned for the culture and leisure surveys above, also here some questions/indicators have been slightly changed over time, which makes some comparisons over time uncertain.
