BIODIVERSITY
There is very little
if any untouched habitats left in Hungary, cultivation or forest
management has been going on for many centuries. Despite this long tradition
of human management the extensitivity of land use assured an equilibrium for
a sustainable cultivation and the protection of nature. Extensive management
has even produced secondary habitats of high natural value, like the hay meadows
and alkaline grasslands. The intensification of agriculture
and the quick development of industry about a century ago brought about a continuously
growing threat to the biota at all levels of organisation (genetic, population,
habitat and landscape level).
Still Hungary possesses
outstanding natural values in Europe, the most important being: wetlands, dry
grasslands, gallery forests and the game stock. This is partly due to a diversified
geomorphology and a transitional type of climatic zone (forest - steppe biogeographical
zone). The variety of bed-rock types provide habitats for different species
groups, the transitional nature of climatic zone enables the occurrence of species
of Atlantic, continental and Mediterranean origin.

Most important threats to all levels of biodiversity are: habitat loss, different environmental loads resulting in the extinction of some species, invasion by alien species, homogenisation (similar species composition) and fragmentation of habitats, pollution and tourism.
Threats to biodiversity have also secondary and complex effects on the natural state, the loads mentioned above in most cases can hardly be separated from each other. Very often a particular impact reinforces the effect of others. For example in polluted areas the vitality of species is effected providing a possibility for aliens and weeds to invade, or a developed system of roads results in habitat fragmentation and loss of species and at the same time the chances of alien species arrival is increased. These consequences can be observed in Hungary all over the landscape.
