Hoe ontwikkel je droog heischraal grasland op voormalige landbouwgrond?

Popis výsledku v původním jazyce

Droge heischrale graslanden staan in Nederland sterk onder druk door voortschrijdende bodemverzuring. Kansen voor uitbreiding van het habitattype lijken groot op voormalige landbouwgrond. Naast te hoge voedselrijkdom hebben deze ook nog belangrijke andere knelpunten. Hoe kunnen doelsoorten zich vestigen als ze niet in de directe omgeving aanwezig zijn? Ook verschilt het bodemleven in een agrarisch perceel in hoge mate van dat in een heischraal grasland. Is het noodzakelijk om de juiste bodemfauna te introduceren, en zo ja, hoe dan?n

How to develop dry Violion grassland on former agricultural land?

Popis výsledku anglicky

Dry Violion caninae grasslands (Galio hercynici-Festucetum ovinae) are endangered in the Netherlands due to continuing soil acidification by nitrogen deposition. As a result, many characteristic plant species of this community have become scarce. However, as a Natura 2000 priority habitat (H6230), quality improvement as well as expansion of its area are necessary. Expansion of this habitat is sought outside nature reserves, on former agricultural land. Constraints for the restoration of dry Violion grasslands on former agricultural lands are the high nutrient concentrations, the absence of typical plants and animal species, and a strongly changed soil biota community. To overcome these constraints, we conducted a five-year experiment on sites with recent top soil removal, in which we added fresh hay, seeds and inoculated soil by means of crumbs, sods or slurry. It appeared that dry Violion grasslands did not develop on former agricultural land without additional measures, because of the lack of target species in the surroundings. Even if species are present, dispersal still appears to be problematic. With addition of fresh hay a 'matrix' of common characteristic Violion species can be developed. The addition of seeds of specific species next to the fresh hay addition is important for certain rare species. Because many characteristic species of dry Violion grasslands have become rare in the Netherlands and will often be absent in the donor sites of the hay, transfer with seeds is the only way they will also profit by the increase in area of the habitat. The effects of soil inoculation were smaller than in some other studies. This could be caused by the dry circumstances and the lack of organic material at the acceptor sites, in which the added biota was not able to survive. Our study demonstrated however that it is possible to stimulate the development of dry Violion grasslands on former agricultural land after top-soil removal by addition of fresh hay of a good donor site solely. Because of the low availability of soil material from well-developed dry Violion grasslands and its restricted effects, soil inoculation is not recommended as an additional restoration measure for the development of dry Violion grassland on former agricultural land.n
