Estudio fitosociológico de la alianza Taeniathero-Aegilopion geniculatae y valor pascícola en la provincia de Jaen (España)

Abstract

Phytosociological study of Taeniathero-Aegilopion geniculatae alliance and its pasture value in the province of Jaén (Spain). Natural grasses communities provide a high quality fodder for a wide variety of livestock (goats, sheeps, horses, pigs, �). In this work, we point out several phytosociological associations that take place in the province of Jaén belonging to the alliance Taeniathero-Aegilopion geniculatae, by using the braun-blanquetist methodology derived from de Zürich- Montpellier school. The detailed study of the currently valid associations dominated by Aegilops geniculata, based on a correlation analysis, lead us to consider the grouping of syntaxa with the same rank (Medicago-Aegilopetum geniculatae, Ononido- Aegilopetum geniculatae and Bromo-Aegilopetum geniculatae), as well as some new status changes and combinations for the subassociations ononidetosum crotalarioidis and medicaginetosum littoralis. Finally, we show a comparative study of the pasture and fodder value of the aforementioned associations.
