Year 2004 was dedicated to silver fir tree – Abies alba Mill.Silver fir tree is considered more than a forest tree species being rooted not only in soil but also in the soul of people around– fact lived and of author of this paper.In the forest La forêt de la Joux”with 2660 ha lying along Franco-Swiss frontier it was elected in 1923 as „President” ansilver fir 53.3m high, 4.60 m perimeter to 1.5 m high and 38.93 m3 total volume. Arround this silver fir tree takes placesall rustic festivities during the year. When on this exemplary have occured dry branches, cracks in the bark, foam on thetrunk and woodpecker holes, silver fir tree was cut, stems and cones has been taken as souvenir and has been replaced byanother „President”.From the history of „Black Forest” are reminded about the silver fir tree specimens which reached 68 m height used forprincipal mast of the commercial Netherlands fleet, about the phenomenon„Tannensterben” and of the hurricanes whohave destroyed spruce stands and opened unexpected horizons for silver fir tree.On the secular silver fir specimens (600 years) from Bavarian National Park were identified 2159 specimens of insects,grouped into 263 species, showing the great biodiversity of silver fir tree forest ecosystems.Keywords: Silver fir tree, „President”, specimens, biodiversity.68
