Effects of different lawn utilization methods on the composition of the flora in the reconstruction program of the wet environment in the Hortobágy

Abstract

Hortobágy – a water habitat with one of the highest diversities – is one of the most important bird habitats in Hungary. Several highly protected species nest in the area but some of the rare species can be found here too. In winter the water habitat of the Hortobágy is a highly important feeding gathering and baiting place for the water birds as well as for predatory birds.
As a result of the intensive cultivation of the area of the past few decades these highly important places have been altered, which resulted in a change and disappearance of the inexpensive flora and fauna.
One of the most important projects of the Hortobágy National Park is to reanimate the water habitat, maintain and handle it in many areas in an environmental protective way.
The dissertation presents an area like this– the Nagy-Vókonya. Following the reconstruction of the area, its water level its original flora and fauna is likely to return to normal. Handling of the area nowadays is solved by raising aboriginal species. Different species browse in a different way forming different habitats for the birds, by this, attracting new species increasing biodiversity.
This dissertation presents the quality differences of the flora formed in the places of differently developed glebes either browsed meaked or uncultivated, as well as eliminated canals ricedams and ricecages through three floracynological examples in the area of Nagy-Vókonya.
As the area is cultivated the dissertation - besides the environmental protective values – analyses the flora from the point of fertilization as well.
The conclusion part gives answers whether cultivational and environmental protection aims can be matched in the same system or not.
