| Résumé : |
The sessile oak (Quercus petraea) is a deciduous tree with a Euro‑Siberian distribution.It is widely spread throughout Europe and (as with other Euro‑Siberian species that constitute the Lathyro montani‑Quercetum petraeae plant community) its southern‑most distribution limit can be found on the Iberian Peninsula. Most of the sessile oak forests on the Iberian Peninsula are located on the Cantabrian Range and the Pyrenees. The NE Iberian Peninsula forests, in particualr, are of special ecological and conservation interest because they grow in a Mediterranean climate and, as such, are on the xeric limit for Quercus petraea. In Catalonia (Spain) the sessile oak forests cover 4,823 ha; the majority (85%) of which are in the Pre‑Pyrenees and the Pyrenees. This study has analyzed the
species composition of the sessile oak forest found on the Catalan Pyrenees using plant community inventories that were carried out between 2016 and 2018. Furthermore, thanks to previous botanists’ work on the Catalan Pyrenees, the current state of the sessile oak forest has been able to be compared with their (historical) data. With a mean of 37 species per inventory, the results show that the sessile oak has a lot of biodiversity. The dominant species are Euro‑Siberian (68%) and the most common life form are the hemicryptophytes (51%); albeit with notable differences between the locations studied. The most relevant finding is that the composition of the sessile oak forest plant community on the Pyrenees has not, as a consequence of global change, altered a lot over recent decades. This result is the opposite of the patterns that have been observed in the rest of the sessile oak forests in Catalonia which, in turn, highlights the excellent conservation status of some of these forests in the Pyrenees and the need to continue along this path to ensure greater resistance against and resilience to climate change. |
