The paper analyzes the elements of the stand structure and proposes
silvicultural measures to improve conditions in the stand of black locust
(Robinia pseudoacacia L.) and common hackberry (Celtis ...occidentalis L.) aged
28 years in Subotica-Horgos sands. The research was performed on three
permanent experimental plots on which selective thinning (T1 and T2) was
performed experimentally in two plots, while one was left as a control plot
(C).Initially, 528 trees for tending per hectare were selected in the
studied age, of which 448 black locust and 80 common hackberry trees per
hectare were selected on T1, and 320 black locust and 208 common hackberry
trees per hectare on T2.In experimental plots T1 and T2 at least one
competing tree was cut down to each tree for tending, and a total of 912 and
1072 trees were cut down per hectare with a total volume of 53-55 m3?ha?1.In
this way, a basis was created for the assessment of the growth response of
trees to selective thinning in the upcoming period.
