A method for surveying the condition of extensive walking track systems

A trial was undertaken of two techniques for assessing the physical condition of walking tracks (trails) over extended distances. A distance-based technique, in which categorical measurements were made at regular spatial intervals, proved to be sufficiently reliable to warrant further development. A refined version of this technique was developed, incorporating an assessment of environmental conditions, and its efficiency and precision were assessed. The technique is likely to be suitable for use in any areas where walking track and environmental conditions are broadly similar to those that occur in the Tasmanian Wilderness World Heritage Area. It may also be suitable for use in other environments, but it would be prudent to conduct additional trials to assess its precision and reliability. Sampling at 20 m intervals, the technique can be used to assess typically 5–7 km of track per day in remote areas. Under western Tasmanian conditions, estimates of the spatial extent of specified categories of impact, derived from 100 sampling points, are accurate at a 95% confidence level to within ±10%. The estimates can be applied in a Limits of Acceptable Change management framework and used as the basis for ongoing monitoring of track conditions.
