Forest Dieback in the Region of South-eastern Slavonia Summary The first part deals with the development of stands in the area of south- eastern Slavonia from the beginning of this century. A special account is given of the catastrophic oak-tree dieback during the 1910—25 period and elm tree dieback in the period from 1930s to the end of the Second World War, when more than 2 million m3 elm tree died or were felled due to disease. Since 1950 all diebacks have been continuously registered in the area managed by »HRAST« Vinkovci, and the former »HRAST« Forestry Enterprise, Vinkovci. During this period of 36 years a total of nearly 1.3 million m3 volume of wood — predominantly pedunculate oak, elm and slightly less ash — were destroyed by dieback. Elm definitely ceased to be an economical species and at present it can be found only in regenerated forests, but is fast deteriorating. In spite of a considerable amount of wood volume felled due to dieback, the present condition of stands in most areas is very good thanks to correct silvicultural interventions and a well organized diagnostic-prognostic service for forest protection. The former main noxious insects of these forests the gipsy moth, brown-tail moth, are now less significant, as most damage is caused by the oak leaf-roll moth and winter moth on oak and the ash borer on ash. Intensive construction of forest communications and making lanes with wide light belts essentially disrupted the ecological stability of these forests and contributed to the intensified activity of early noxious incests on the oak. The possible construction of the Dunav—Tisa canal and raising of the ground water level would disrupt the relation between plant communities in this region and with this the stability of productive capability of these forests. |
