20.500.12556/DiRROS-25600 Vegetation map of the nature reserve Mykhailivska Tsilyna (Ukraine) The nature reserve Mykhailivska Tsilyna is located in Sumy region, in the northern part of Forest-Steppe zone of Ukraine. The area of virgin northern meadow-steppe is protected there. A new, large-scale vegetation map (scale 1:10000) of the reserve (the first one in its new borders) had been created. The main units of mapping are complexes of plant communities in ranks of associations, subassociations and variants. In total, 27 such complexes and 10 units of another rank have been identified. The map shows vegetation cover changesover a period of strict protection (2011–2023). The most common classes of vegetation in the reserve are: Molinio-Arrhenatheretea, Artemisietea vulgarisandFestuco-Brometea. Main changes in the vegetation cover of the reserve’s old territory are manifested in the form of steppe transformation: from meadow-steppe areas to more mesic shrub-steppe with dominating Cytisus ruthenicus and forb communities with dominating Euphorbia semivillosa. In these communities can be seen a decrease in the share of tussock grasses and an increase in the share of rhizomatous grasses. The same process is occurring in the reserve’s new territory, but phytocenoses are different there. Naravni rezervat Mykhailivska Tsilyna se nahaja v regiji Sumy v severnem delu gozdno-stepskega območja Ukrajine. Območje nedotaknjene severne travniške stepe je tam zavarovano. Izdelana je bila nova vegetacijska karta rezervata v velikem merilu (merilo 1:10000) (prva znotraj novih meja). Glavne enote kartiranja so kompleksi rastlinskih združb na nivoju asociacij, subasociacij in variant. Skupaj je bilo identificiranih 27 takšnih kompleksov in 10 enot drugih rangov. Zemljevid prikazuje spremembe vegetacije v obdobju strogega varstva (2011–2023). Najpogostejši razredi vegetacije v rezervatu so: Molinio-Arrhenatheretea, Artemisietea vulgaris in Festuco-Brometea. Glavne spremembe v vegetaciji starega ozemlja rezervata se kažejo v obliki preobrazbe stepe: od travniško-stepskih območij do bolj mezičnih grmičasto-stepskih s prevladujočo vrsto Cytisus ruthenicus in travniškimi združbami s prevladujočo vrsto Euphorbia semivillosa. V teh združbah je opaziti zmanjševanje deleža šopastih trav in povečanje deleža trav z živicami. Enak proces se dogaja na novem ozemlju rezervata, vendar so tam fitocenoze drugačne. vegetation mapping steppe vegetation vegetation dynamics problems of strict protection regime in the steppe vegetacijska karta stepska vegetacija vegetacijska dinamika težave strogega varstva v stepi true false true Angleški jezik Slovenski jezik Imetniki avtorskih pravic na prispevkih so avtorji Neznano 2026-01-24 14:50:36 2026-01-24 14:50:37 2026-01-25 03:46:00 0000-00-00 00:00:00 2025 0 0 str. 179-198 št. 2 letn. 24 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-02-08 582(251)(477) 1581-4661 10.3986/hacq-2025-0015 253000451 https://ojs.zrc-sazu.si/hacquetia/article/view/12153/12438 1 aad67201-f92b-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38802 HACQUETIA_24-2_2025_4_Larionov.pdf HACQUETIA_24-2_2025_4_Larionov.pdf 1 0F4915808528DB99026C6630863CAFFA 95ae21933d33f3c54431e51eeea54aa6262f7268ad89a60e30273fd2b8f1940c 12d67e87-f92c-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38803 Znanstvenoraziskovalni center Slovenske akademije znanosti in umetnosti Hacquetia 0 0 0
