6. The vegetation map 1:5000 makes possible a yet more intensive separation of stands (sub-compartments) and a complete transition to actual forest management by stands. 7. Melioration of Crnava Brook and the digging of new ditches has affected the stands of Opeka. Narrow-leaved Ash has begun to dry up, Field Elm has already dried up, while Black Alder pushes into their places. For the sake of a proper mixture proportion Pedunculate Oak must be assisted in future an introduced into openings and clearings, because the process of the natural change of the species has quite suddenly been interfered with through drainage works. With the paper is enclosed a bibliographical survey of scientific research works perfomed in the mentioned forests until the end of 1971. |
