- •
We investigated the role of abiotic factors in the settlement of Posidonia oceanica on rocks.
- •
We performed geomechanic and petrographic analyses and scuba diving surveys.
- •
A predictive model to individuate the theoretical depth of the meadow upper limits was applied.
- •
P. oceanica occurs only on the strongest lithotypes whilst weak rocks remains unvegetated.
- •
The predictive model is less applicable on rocks due to plant resistance to hydrodynamic forces.
