Late March signals the start of a battle for light. Timelapses show billions of plants, shrubs and trees racing to be the first to make use of the sun's life-giving energy. Bats and bees come out of hibernation and birds and animals begin their own perilous race; to breed. As spring becomes summer the rising temperatures trigger plankton blooms in the sea. Mayflies hatch in their millions attracting attacks from acrobatic brown trout in the rivers below and duckings leap from the water to pluck the mayflies from the air.
