“…Equally worryingly, over 60% of the sample did not carry out any monitoring of the trail after it was set up, so trail developers are unaware of visitor volume and the effectiveness of signage, interpretative materials and marketing strategies. Trail usage is difficult to monitor, particularly in remote regions or in busy urban centres where users cannot be readily differentiated from other visitors (Hayes & MacLeod 2008). However, the positive economic impact of the Virginia Creeper Rail Trail in Virginia, US and the Path to Progress Trail in Pennsylvania, US, have both been measured using expenditure surveys of trail users and an analysis of existing site reports respectively (Strauss & Lord, 2001;Bowker, Bergstrom, & Gill, 2007) In neglecting to evaluate impact and to monitor trails, developers may also be unaware of potential areas of conflict inherent in some trails, for example the "pilgrim-tourist dialectic" in the case of the Camino de Santiago where pious and secular motives may clash (Murray & Graham, 1997).…”
