Vegetacija nižinskih suhih vresav v srednji Evropi (Euphorbio cyparissiae-Callunion vulgaris) je v upadanju zaradi opuščanja tradicionalnega gospodarjenja in to se kaže v postopnem zaraščanju z lesnatimi rastlinami in spremenjenem vnosu hranil. Za obnovitev sestojev z vreso, ki so izginili, smo uporabili pašo z nizko intenzivnostjo in košnjo, ki sta tradicionalno priporočena načina za obnavljanje vegetacije z vreso (Calluna vulgaris) iz semenske banke. Raziskavo smo opravili v naravnem rezervatu Zlatnice, ki se nahaja v severozahodnem delu Prage (Češka republika). Vzpostavili smo sistem stalnih 1 m² ploskev. Za obnovitev vegetacije z vrsto Calluna vulgaris sta bila uspešna tako paša kot košnja. Pokrovnost vrese se je povečala dve leti po začetku poskusa s pašo, na površinah s košnjo pa se je značilno povečala tretje leto in vrednosti so bile primerljive s pašenimi površinami. Redna paša je ovirala povečanje pokrovnosti zelišč, medtem ko se je njihova pokrovnost povečala po posamezni košnji. Košnja je tudi vplivala na povečanje pokrovnosti mahov. Poizkus je pokazal, da je slabo intenzivna paša ovac in koz verjetno najbolj primeren način obnove suhih vresav na plitvih, s hranili revnih tleh, po več kot 20 let od uničenja vresave. Košnja je bolj zahtevna, pojavlja pa se tudi možnost razraščanja nezaželjenih zelišč in lesnatih rastlin, kar zopet vodi v degradacijo vegetacije z vrsto Calluna vulgaris.Prenosi
