This month, Melvyn headed out to the coast at Saltfleetby - Theddlethorpe Dunes National Nature Reserve to see what work our wardens get up to whilst the rest of us are tucked up in bed.

From bat surveys and moth trapping to the chorus of natterjack toads across the reserve, plenty of work is still going on once the sun sets and wardens Matt and Ruth help shed some light on the work they get up to once it gets dark.
