Evaluation of pastures along the River Jaba (Ságvár): Papers presented at the „Timely questions in grassland and game management” scientific conference (Hungarian Academy of Sciences – Kaposvár University, 18-19 May 2006)
62-72Views:59The valley of the river Jaba and the hilly country of its small catchments area situated in Trans-Danube near the lake Balaton and plain of Mezőföld. It has not yet been discovered botanically till now in details. It proved to be poor of minerals and energy sources. There remained next-to-natural relic habitats under traditional land-use conditions because of its orographical, mineralogical and pedological properties.
The aim of the present study is counting of vascular plants and evaluating of steppe communities of Salvio-Festucetum rupicolae and Cynodonti-Poëtum angustifoliae from the point of view of nature conservation and utility for pasturing. -
Comparative study of loess steppe pastures with/without domination of bluegrass (Bothriochloa ischaemum)
55-61Views:49There have been floristical and plant sociological investigations carried out for several years in Jaba river valley (Somogy county, Hungary) regarding typical and degraded Salvio- Festucetum rupicolae loess steppe community. Bluestem (Bothriochloa ischaemum) is becoming dominant species of grassland due to disturbance and the alteration of sheep-walk usage. Phytosociological records and harvest sampling have been used for comparative study of typical and Bothriochloa grass dominated derivatives by randomly spotted quadrats. The naturalness and quality (hay-) value for the typical and phytomass for Bothriochloa type showed a higher grade. The Sørensen index of similarity was lower then expected for the floristical relationship of the investigated vegetation types.
