Influence of allochtonous stands introduced Douglas-fir (Pseudotsuga menziesii) on understory

vegetation was studied on 44 plots in Czechia territory. Stands had to be 60 years old at least. Norway

spruce (Picea abies), European beech (Fagus sylvatica), oaks – Sessile and Pedunculate (Quercus petraea

and Q. robur) and other commercial tree species (Tilia cordata, Acer pseudoplatanus, Pinus sylvestris

and Larix deciduas) stands were chosen to compare. Compared stands had always the same habitat

conditions as Douglas-fir plot.

Results have shown that Douglas-fir stands have not unambiguous characteristic species of the herb

layer, but they show higher increase of nitrophilous species.
