A contribution to the study of stand degradation process on the territory of Fruska Gora National Park

Abstract

We analyzed the process of stand degradation of individual forest ecosystems in the region of the zonal community Tilio-Carpino-Qurcetum robori-cerris Jov. 79 located in the western part of Fruska Gora National Park. Degradation occurred is consequence to regeneration felling and it progressed towards the extinction of oaks, first of all the valuable pedunculate oak and Vergilius's oak, and then also Turkey oak. The analyzed mature stands were degraded coppice and mainly predominated by the Turkey oak in the tree stratum. In juvenile stands, often initially well regenerated with Turkey oak, the dominant species in the tree stratum are lime, hornbeam, flowering ash, field maple and other secondary species, predominantly of coppice origin. Restitution of the degraded stands is possible by applying an adequate regeneration system. Taking into account the primarily protective function of the analyzed forest ecosystems and the fact that these are degraded and coppice stands, the system of regeneration should be based on combined restoration.

Morphological variability of Quercus robur L. leaf in Serbia

“…In recent decades, there has been an evident decline of pedunculate oak forests in Europe, Asia, the Balkan Peninsula, as well as in Serbia. This has been caused by a number of biotic and abiotic factors, such as climate change, site conditions, over-exploitation, or insufficient and inadequate regeneration of pedunculate oak forests (YAKOVLEV and KLEINSCHMIT, 2002;BOBINAC, 2003;THOMAS et al, 2003;BALBOA-MURIAS et al, 2006;HELAMA et al, 2009).…”

Multi-criteria approval for evaluating landscape management strategies (Case study: Fruska Gora National Park)

“…Fruška Gora is proclaimed a national park in 1960 and is well known for its remarkable cultural and natural values. The total actively protected area occupies 25,393 ha and recent studies identified several problems in the area, such as spread of invasive species along with the suppression of oak trees [Bobinac 2003;Vasić et al, 2012], intensification of erosion processes [Dragićević et al, 2013], etc. Experts suggest that properly defined landscape management strategies could preserve existing park's qualities and ensure the major problems in the park to diminish in the near future [Vlada AP Vojvodine, 2011].…”

Deliberation over species change in a monodominant sessile oak stand (Quercetum petraeae Cer. et Jov. 1953., subass. tilietosum) - A case study in ”Djerdap” National Park

“…Сличан процес регресивне сукцесије је претходно утврђен на подручју Националног парка "Фрушка гора" у ширем појасу мешовитих храстових шума, где је у процесу обнављања састојина чистом и оплодном сечом, занемариван регенеративни потенцијал липе. У оквиру претходно добро подмлађених састојина с храстовима манифестовала се регресивна сукцесија и формиране су састојине с доминацијом липе, претежно изданачког порекла (Bobinac, Radulović, 1997, Bobinac, 2003b. На подручју Националног парка "Фрушка гора" изданачке састојине су заступљене на преко 80% површине, а липе су најзаступљеније врсте и имају учешће у укупној запремини преко 37% (2002).…”

“…A similar process of regressive succession was previously determined in the area of National park "Fruška Gora" in the wider belt of mixed oak forests, where the regenerative potential of silver lime was neglected in the process of stand regeneration by means of clear cutting and shelterwood system. Within the previously well-regenerated stands with oaks, a manifestation of regressive succession occurred so silver lime dominated stands were formed, mostly of vegetative origin (Bobinac, Radulović, 1997, Bobinac, 2003b. In the area of the National park "Fruška Gora", coppice stands were represented in over 80% of the area, with lime forests as the most represented species with a volume share of 37% (2002).…”
