Got a fear of reptiles? You might want to steer clear of Hampstead Heath, where there's been a rise in the number of snakes spotted in the grass. And we don't mean a load of shady characters, we're talking about actual grass snakes.
The City of London Corporation runs a grass-snake monitoring programme on the Heath, and they've noticed a significant increase in sightings around the bird sanctuary pond since the programme launched in 2009. But don't panic, grass snakes aren't venomous and they only eat frogs, toads, newts, young birds and, er, occasionally small mammals, so you should probably be okay.
