Two coastal walk trails in south-western Australia were subjected to a specific soil erosion and microtopography assessment between 2004–2007. A point intercept (PIN) frame was used to evaluate change over time to the trail profile. Estimates of soil loss are quantified and discussed in relation to previous historical use and a lack of appropriate management intervention. The results show that soil erosion of up-slope areas and deposition in low lying areas is active on the sections of the Bald Head and Peak Head walk trails that received PIN frame treatments. The data show that a long-term data set is required to accurately analyse changes to soil microtopography and to show statistically significant differences in cross sectional area of trail profiles. It was also found that maintenance features alone do not guarantee the sustainability of a coastal walk trail. Appropriate planning, initial trail location and ongoing maintenance are essential components of a sustainable trail management program.
