Conclusion

In semi-natural pastures of Plana de Vic, most of the main species in the stablished vegetation are poorly represented in the soil seed bank, but are able to thrive or even dominate via vegetative persistence and expansion. The changes in land use occurred during the last half century have promoted species impoverishment at stand scale, and fragmentation of semi-natural plant communities at landscape scale. This, together with the low dissemination ability of most pasture species and the limited role of the soil seed bank, impair the conservation or recovery of plant diversity of this species-rich landscape.
