Pasture vegetation near the village of Idjos

Abstract

A pasture on the solonchakic solonetz soil in the vicinity of the village of Idjos (Banat, Serbia) was found to harbor 137 plant taxa (129 species, 7 subspecies and 1 variety). The plant cover they formed was specific from the ecological, phytogeographical and phytocoenological points of view. The specific ecological feature of the surveyed plant cover was that 47 or 34.31% of the recorded taxa were rated with the ecological index S+ due to their ability to grow in saline soil. The specific phytogeographical feature of the surveyed plant cover was the presence of two Pannonian endemics, Plantago schwarzenbergiana Schur and Statice gmelini subsp. hungaricum (Klokov) So?, and two subendemics, Puccinellia limosa Holmb. and Roripa kerneri Menyh. The specific phytocoenological feature of the surveyed plant cover was the presence of two phytocoenoses from the class Phragmitetea Tx. et Prsg. 1942 (ass. Scirpo-Phragmitetum medioeuropaeum and ass. Bolboschoenetum maritimi continentale), one phytocoenose from the class Molinio- Arrhenatheretea Tx.1937 p.p., Br.-Bl. et Tx. 1943 p.p. (ass. Trifolio-Lolietum perennis) and ten phytocoenoses from the class Festuco-Puccinellietea So? 1968 (ass. Puccinellietum limosae, ass. Pholiuro-Plantaginetum tenuiflorae, ass. Hordeetum histricis, ass. Agrostio-Alopecuretum pratensis, ass. Agrostio-Beckmannietum, ass. Halo-Agropyretum repentis, ass. Poeto-Alopecuretum pratensis halophyticum, ass. Artemisio-Festucetum pseudovinae, ass. Trifolio-Festucetum pseudovinae and ass. Achilleo-Festucetum pseudovinae). The presence of 34.31% of taxa rated with the ecological index S+, the presence of two Pannonian and two sub-Pannonian floristic elements and the predominance of stands from the class Festuco-Puccinellietea So? 1968 led us to conclusion that the pasture near the village of Idjos (Banat, Serbia) is a part of the halobiome of the Pannonian Plain.
