Douglas-fir (Pseudotsuga menziesii) stands and its herb layer in a Czech commercial forests
Abstract
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.
