Résumé :	Within the framework of Natura 2000-conservation planning, survey and mapping of Capercaillie Tetrao urogallus in the Bavarian SPAs (special protection areas) has been in progress since 2006. The process from modelling the "search area" up to the complete action plan is fulfilled in large parts of the special protection areas using a standardized method. Now results allow both assessment of relative population density and essential habitat structure. In seven SPAs 184 signs of capercaillie were identified at 3782 survey points, this corresponds to a mean activity of 4.9 %. In total 12.070 ha of very important habitat could be identified, surrounded by areas where additional conservation measures are planned. A result of the inventory was the high amount of old coniferous-dominated stands with a sparse canopy cover (52 %). Within the potential habitats capercaillie preferred older (mean age 131 years) and lighter (37.6 % mean canopy cover of dominant tree layer) stands. As a result of survey and mapping, conservation measures are planned. The aim of this article is to explain the process of Natura 2000 capercaillie conservation in Bavaria and discuss previous results.
