This Technical Paper describes a collaborative effort to explain the reduced growth at time of canopy closure or later of Sitka spruce on parts of the South Wales coalfield. Stem analysis showed that growth had declined steeply over a period of about four years. Decline was associated with thin crowns and with bending of the tops of some of the trees.
