In the Czech Republic, Norway spruce (Picea abies) is considered autochthonous in the mountains as well as at lower altitudes. However, certain papers admit its originality only in the mountains. Three historic maps (from the years 1746, 1853, and 1946) showing tree species composition, published in the guide for FAO excursion in Czech forests in 1956, were evaluated and compared with the current tree species composition. The studied forest estate is located in the uplands, in the 4th vegetation belt. The data show that spruce made a substantial part of the tree species composition on Stagnosols as well as Cambisols. Even on Podzols, dominated by pine, spruce played an important role. While the spruce and pine composition was increasing at the expense of fir, oak proportion remained roughly the same. Comparing the tree composition on the evaluated area in the years 1746 and 2001, the composition of spruce increased from 39.8% to 46.4%, of pine from 32.2 to 42.2%, while that of fir decreased from 20.7 to 1.8%.
