Species are not equally detectable, and this should be considered at the moment of choosing ecological indicators and considering sampling efforts. Indexes that permit ranking gilled species according to their abundance, permanency and basidiomes features were constructed. The same indexes were used to evaluate sampling effort and efficiency: more than 2 hours of continuous work affects negatively the capability of finding less detectable species. Ranking species is a practical solution to organise abundance datasets, and can be easily applied to find patterns of species relevance and detectability to better understand our findings and even to ensure optimum field work efficiency.
