The sessile oak's decline phenomena has been analyzed in three protected areas of the N-E Piedmont region (N-W Italy), where this species is an important component of the Po plane forest structures. The utilized parameters are: crown clearness, leaf depigmentation, and presence of epicormic branches. We found mainly two different situations: one in better conditions where the species is at its ecological optimum, the second, where trees developped on fallows land, shows an elevate rate of declining trees.

Abstract
The sessile oak's decline phenomena has been analyzed in three protected areas of the N-E Piedmont region (N-W Italy), where this species is an important component of the Po plane forest structures. The utilized parameters are: crown clearness, leaf depigmentation, and presence of epicormic branches. We found mainly two different situations: one in better conditions where the species is at its ecological optimum, the second, where trees developped on fallows land, shows an elevate rate of declining trees.
