Summary: | The aim of this paper is to present a numeric-statistical model by which it
is possible to evaluate the quality of the observed grassland upon floristic
and vegetation assessment. Thanks to this new methodological approach, the
impact of each individual plant species on overall quality of the grassland
could be estimated. The main goal was to determine species which
significantly determine the pastoral value of the grassland. The quality
(pastoral value) of the grassland was calculated using the numerical values
of quality index of each individual species of each relev? of the community.
For testing this numerical method, the total of 11 relev?s of 4 grassland
communities of hilly-mountainous area of Mt. Kopaonik was used. Analyzed
vegetation includes previously unpublished phytocenological relev?s as result
of our own field research. All analyzed relev?s were obtained using the
method of the Swiss-French phytocenological school. The results showed that
the best and the worst quality were determined for the ass. Festuco-Brometum
erectii, and the ass. Nardetum strictae, respectively. Species that highly
contributed to good and bad quality of grassland were Arrhenatherum elatius,
Festuca rubra, Dactylis glomerata, Trifolium repens, etc., and Carduus
alpestris, Hieracium hoppeanum, Ornithogalum umbelatum, respectively. |
