RESUMO

The trail evaluation and monitoring have been undertaken in detail throughout Brazilian protected areas. However, stairs, as a component of the pathway used by the visitors, are not taken into account. This kind of infrastructure is present more frequently in steeper terrains as where Alto Ribeira Touristic State Park (PETAR) is located, the selected area for this research. The goals of this research were to describe and evaluate the elements that contribute to the wood stair degradation; verify if these stairs can be evaluated in the same way as the rest of the trail; and based on the results suggest a preliminary protocol to evaluate and monitor this kind of structure in natural area trails. Based on the results found, the objective is to contribute to the trail management in natural areas, especially in protected areas. The detailed data on the stairs was collected in July 2010. The analysis of the data demonstrates: a) the depression quantity on the tread was affected by the length of the stair section; b) the intensity of erosion and puddle were not affected by the tread grade; c) despite the fact that ergonomics didnt show correlation with the negative impacts, it can interfere in the quality of user experience and safety; d) the solar exposure influences the quantity of puddles; e) the presence of canopy cover can minimize raindrop impact; f) better training is needed for the staff involved in trail management; and g) the stairs need differentiated evaluation and monitoring from the rest of the trail. The following indicators were selected for the preliminary protocol to evaluate and monitor the PETAR wood stairs: 1) presence of exposed tree roots; 2) tread roughness that makes it difficult to walk; 3) presence of social trails and its causes; 4) step width; 5) step depth; 6) step height; 7) length of the stair section; 8) location of the deeper depression spots in the steps; 9) drainage structures obstructed by fallen vegetation or sedimentation; 10) presence of drainage structure at the top of the stair section; and 11) erosion in the bottom of the steps.
