Tartalmi leírás:
The riparian forests of Hungary are unique in all of
europe. These are parts of the few habitats where a semi-
natural vegetation could have remained or re-grown, in spite
of the human interference. In 2002 we wrote up the nearly
10 years of study about the forests of Beda-Karapancsa, in
the lower Danube riparian area. We evaluated more than
8000 ha area on the digital map and data-base of the Duna-
Drava National Park and we gained the data about the forests
from the Forestry Database of the National Forestry
service.
Together with our colleagues we did detailed botanical and
ornithological research in 15 parts of these forests. Thematic
maps were made to show the distribution of exotic tree spe-
cies as well as the locations of protected plant and bird spe-
cies. During this research it turned out that the percentage
of the old-grown oak-ash-elm hardwood forests (
Fraxino
pannonicae-Ulmetum
) is extremely low, hardly reaching 2%.
With cautious estimation this is less than one tenth of the
potential habitats, moreover only strongly fragmented patches
of these forests exist. In many cases their places were taken
over by monocultures consisting of exotic tree species, such
as Black Walnut (
Juglans nigra
) and Poplar hybrids (
Populus
x. euramericana
).
