Abstract

Naravni rezervat Škocjanski zatok, ki leži ob mestu Koper, je specifičen pašni ekosistem, kjer zaradi poplavne oz. močvirske narave prevladuje navadni trst (Phragmites australis Cav.). Na območju se od leta 2008 pasejo tudi konji, pri katerih se je vsako leto pojavila bolezen laminitis. V okviru naloge smo analizirali botanično sestavo, sezonsko rast ter vsebnost vodotopnih ogljikovih hidratov (VOH) v trstičju in travni ruši, kot možni vzrok za pojav bolezni. Obravnavali smo štiri raziskovalne ploskve, na katerih je v letu 2016 potekalo skozi celo leto vzorčenje za laboratorijske analize, floristični popisi in odkos zelinja za merjenje prirasti zelinja. Ugotovili smo, da so precej drugačne razmere v oljčniku v primerjavi z Zatokom. V oljčniku je bolj suho, vegetacija je kserofilna in tudi nižji prirast zelinja. Ugotovili smo tudi, da je VOH v rastni sezoni najvišja spomladi, tekom dneva pa pozno popoldan. Na podlagi ugotovitev raziskave lahko načrtujemo pašo po strokovnih smernicah, ki združuje tako prehranske vidike konj kot ohranjanje tipičnih habitatov rezervata.

Secondary title: Using botanical composition and content of non-structural carbohydrates in grass and reed biomass on pastures of Škocjanski zatok nature reserve for grazing planning
Secondary abstract: The Škocjanski zatok Nature Reserve, located close to the city of Koper, is a specific grazing ecosystem where due to frequent flooding, common reed (Phragmites australis Cav.) is a dominant plant spieces. Laminitis disease has appeared every year since 2008 when horse grazing was initiated in the reserve. In this thesis we focused on botanical composition of grazed vegetation, its seasonal growth and content of water-soluble carbohydrates (WSC) with latter being frequently reported as possible cause for the laminitis disease. Four different research plots (olive groove, two wet grasslands, reed stand) subjected to horse grazing were established where the sampling for WSC analysis, floristic inventories and biomass harvesting were carried in year 2016. We found that vegetation parameters in the olive groove strongly differ from both grassland plots; in the olive groove the vegetation is xerophylic with lower growth rates in comparison to other plots. Furthermore, we found out the WSC is the highest during spring and in late afternoon for seasonal and daily changes, respectively. The results of the research are crucial to formulate good expert guidelines, which combine both the nutritional aspects of vegetation and the preservation of valuble habitats in the reserve.
