The manuscript presents maps of internationally important wetlands located in the Kis-Sárrét (Hungary) from 1860 to 2008. The study area is located in south-east Hungary, in the Körös-Maros National Park and covers 8048 ha. For the historic map review, we used digitized data of topographic maps from the period of two military surveys and the Second World War. We also made habitat maps of the area in 2007 and 2008. Data processing, and the establishment of a database of the mapped area, was made using QuantumGIS 1.7.0 and Esri ArcView GIS 3.2. Maps were produced using Esri ArcGIS 10.0 and show where and in what ratio the once extensive wetlands occurred, how they changed and in which part of the area they survived in different mapping periods. They provide a point of reference for the monitoring of wetlands, contributing to the long-term conservation of these valuable habitats. Maps and diagrams show that between 1860 and 1944 wetland extent decreased by half. The ratio of natural, 'purely' wet habitats reaches only 4.67% now. Wetlands typically occur in habitat complexes, therefore not 'purely' wet habitats (20.77%) also have to be taken into account. Considering this, and a recent habitat reconstruction, the extent of wetlands is more favourable today than it was in 1944. However, to sustain them requires care and well-planned management to which the maps presented here provide an important basis.

A Gödöllői-dombság területén, Kartal határában 1994 és 2012-ben búzatáblában, erdős-gyepes és csak gyepes, kaszált szegélyben készítettünk érintkező kvadrátokból 6−6 transzszektet. A fajok borítási értékeit 5-ben jegyeztük fel. Az adatokat kétutas klaszter analízis és DCA analízis során értékeltük. Az eredmények alapján az erdős-gyepes transzszektek szegély fajkészlete teljesen átalakult, elszegényedett és az invazáziós bálványfa vált uralkodóvá. A gyepes szegély továbbra is nagy fajszámot tartalmazott. A gyep kezelése, kaszálása a fajszám megőrzésében jelentős szerepet játszott. A szántóföldi kvadrátokban általános, hogy a szegélytől haladva a fajszám csökken. A szegélyhatás erdős-gyepes társulásnál csak az első kvadrátban érvényesül, ezzel szemben a kaszált útszéli mezsgyében a 2. kvadrátban is kimutatható nagyobb fajszám.

We studied the vegetation of a 260 ha Hungarian Grey Cattle pasture near Páskom, which can be found in Zámoly basin. We carried out our surveyes in May 2012. The pasture can be divided into five parts. One part, approximately the half of the area (150.83 ha), is an old-field grassland, which was overseeded 20 years ago. The other half of the pasture was restored (109.17 ha) in 4 different ways in 2009 and then was mowed until 2011. Seven relevés were made in each part of the pasture (the occurence of species and their cover value were recorded). The aim of our study was to compare the effects of the different restoration methods and mowing on the botanical composition of the pasture. The results showed, that the grassland restored with hay transfer method was the most similar to the natural conditions. The greatest number of species was recorded in that part and the species of natural grasslands become dominant. The directly sowed and the spontaneous grassland parts separated chiefly from the semi-natural 20 years old grassland.
