A házi vízibivaly (Bubalus bubalis) legeltetés, mint élőhelykezelési és inváziós fajok elleni alkalmazási lehetőség
47-53Megtekintések száma:499A természetvédelemben ma globális probléma az invázíós növényfajok agresszív terjeszkedése és az értékes gyep megőrzése. Ennek alapján a következő kérdés fogalmazódhat meg, hogy mely állatfajok, fajták alkalmasak az élőhelyek kezelésére? A vízibivaly alkalmas-e a gyepkezelésre és milyen mértékben? Az áttekintő munkával az eddigi eredményeket nézzük át, kiemelve olyan hazai területeket, ahol már előzetes eredményeink vannak, illetve korábbi adatok már születtek. Ez alapján a Zámolyi-medence lápjaiban az invazív Solidagot teljesen visszaszorították, a legelőt teljesen átalakították, és a domináns faj a Sesleria uliginosa lett. Szintén a Zámolyi-medence a tómeder területén jelentős florisztikai és fiziognómiai eltérések mutatkoztak a növényzetben. Megállapíthat, hogy a bivalyos legeltetés alkalmas élőhely-kezelési módszerként mind száraz gyepben, mind nedves gyepben. Ezért a bivalyokkal való legeltetés amellett, hogy hatékony a Solidago gigantea elleni védekezésben, mind természetvédelmi, mind a gyepvegetáció gazdasági szempontból sikeres. A hosszú távra tervezett munka első állomása a vízi bivalyra vonatkozó munkák áttekintése.

A gyepek helyreállításának lehetőségei különböző élőhelyeken, különböző legelő állatokkal: Áttekintő esettanulmányok II: Kecskelegelők
43-46Megtekintések száma:23In this summary overview, we present the findings of phytosociological surveys conducted in vegetation types subjected to goat grazing—excluding the control meadows—across seven different study sites in addition to four settlements located in Transdanubia and the North Hungarian Mountains. The areas are also evaluated from a grassland management perspective. Furthermore, we explored the potential use of two invasive species (Solidago gigantea and Calamagrostis epigeios) as goat fodder, and we included a mown meadow as a control. The primary aim was to assess the species richness and ecological value of these areas under varying levels of grazing pressure and grassland management strategies, particularly in terms of conservation and pasture use.
The most degraded plant communities were observed in Nagyréde and Kaposdada, where overgrazing had occurred. This was evident in species composition, as these areas were the least species-rich and showed significant infestation by ruderal species. In contrast, the most favorable outcomes—both for conservation and for grassland management—were found in sites that were initially mown and subsequently grazed by goats. The results suggest that vegetation types developed under light grazing pressure were more beneficial from a grazing perspective. Overall, the study indicates that a combination of light grazing and mowing is the most suitable management approach for maintaining and utilizing these semi-dry grasslands sustainably.
Additionally, both invasive species may have potential for use as fodder when harvested at appropriate phenological stages and supplemented with additional feed, although not for meat production purposes.

Gyeprestaurációs esélyek lehetőségek különböző élőhelyeken, eltérő állatokkal végzett legeltetés során.: Áttekintő esettanulmányok I: fás legelők, erdőirtások
41-46Megtekintések száma:746Since 1992, data on the vegetation of the various grasslands in the country have been collected continuously and in recent years the vegetation of these areas has been surveyed repeatedly to monitor changes. Our aim has been to identify the conservation values and grassland management values of grasslands grazed by different animals, grasslands and wooded pastures that have been planted or restored. In the Pannonian region, we have also carried out studies in lowland mid-range, hilly areas. Areas grazed by horses, Hungarian grey cattle, sheep, goats and domestic water buffalo. The results of grazing with different animals at several study sites have been monitored and have been continuously monitored since 1994. In this paper, a brief overview of the results of the conversion of wooded pastures and deforested areas to pasture is presented.
Results from three wooded pastures and one shrubland are summarised. Results from Hungarian grey cattle sheep and Hungarian domestic buffalo pasture are summarised. In all areas, grazing was successful in maintaining habitats. The maintenance of the scrub area and the preservation of its mosaicity were best ensured in the Hungarian grey cattle pasture. Sheep were responsible for maintaining the grassland vegetation. Water buffaloes ensured the maintenance of the pasture.
