At the beginning of January, 2012, the massive ash tree at Thornhill Square, N1, collapsed in spectacular fashion. The stump shows that its trunk was hollow, rotted internally and home to many borers or beetle larvae. Its fall took with it some nearby smaller trees and bushes and part of the railings. Many ash trees are in decline, shown by reduced growth, a thin crown and the die-back of branches. This grand old tree was showing such signs when photographed in July 2011.

Nearly seven years later, in November 2016, the ash stump has produced strong, new wood

 

The regenerated growth promises to become a fine replacement tree
