A group of swifts follow the curve of the Thames around Twickenham towards Richmond. The echo from a greater spotted woodpecker tapping a hollow Beech in Petersham Meadow. A grass snake, disturbed, slithers back into the undergrowth. A rabbit bounces back under the brambles. Fungi everywhere, connecting through an underground mycelium. And an ancient Oak contemplates the next hundred years on the Ham Cross Plantation.
