2001
Cafourek, J. (Lesni Skolky, Tisice (Czech Republic)
Exotic species take up the area of about 35,000 ha in forests of the Czech Republic, that means about 1.5 % of the forested area. The share 7 % is considered as the upper limit of the area to be planted with exotic species in the Czech Republic`s forestry. Douglas fir should take up a half of this area. The present area of Douglas fir in the CR forests is 3,950 ha. Suitability of Douglas fir provenances for the conditions of CR is investigated on research provenance plots. There have been seven research plots of the area 5.60 ha until now on which 87 provenances are studied. Newly established provenance plots should provide further results describing suitability of new provenances for the needs of the CR forestry. But this is till now limited by an Act of Czech National Council.
