Fungal conservation needs a good knowledge of the ecology and distribution of target species. A computerized database is essential to store large amounts of records which can be enhanced and corrected. Three examples are given to illustrate the potential of a database for conservation management and developing conservation strategies. Distribution maps and especially estimated areas of occurrence, obtained by modelling, help build reliability. Associated organism of wood-inhabiting fungi identifies pioneer trees as exceptionally rich woody substrata which have implications in forestry management. The correlation between area size and number of inhabitants reveals the importance of urban areas for conservation.
