Planting of different-sized tree transplants on arable soil

On the arable land of the Rosovka Stream alluvium in the Czech Republic, a windbreak containing native woody species, was planted within a restoration project. This study evaluates the effect of that planting of three different tree sizes, on the rate of growth. The sizes of transplants employed in this study included small (1.0–1.5 meters tall), medium-sized (2.0–2.5 meters tall) and large (with a trunk circumference of 0.1–0.12 meters). The following native tree species, from the Eurosiberian region, were used: Quercus robur L., Carpinus betulus L., Fraxinus excelsior L., Acer campestre L., Acer pseudoplatanus L., Tilia cordata Mill., and Prunus avium L. Growth rates were monitored over a five-year period. Small transplants had the highest growth; they grew approximately 0.4 meters more than transplants from the other size categories. Our results show that the selection of the size of transplant has a significant impact on development and growth. However, differences in the post-transplant responses of individual species were found.
