A scrambling plant, Meadow vetchling has yellow flowers. It is a member of the pea family and can be seen on rough grassland, waste ground and roadside verges.

A fierce predator of small fish and flying insects, the brown trout is widespread in our freshwater rivers. It is has a golden body, flanked with pale-ringed, dark spots.
