The natural cycle of growth and pasture is maintained on Walthamstow Marshes.
Cattle are removed at Candlemas, 2 February. At Lammastide, starting on Lammas Day 1 August, the grass is cut or cattle brought back.
This weekend Lammas Day will be kept on Walthamstow Marshes with a series of events including a scything competition.
This evening Saturday 1 August, between 7pm and 8pm, visitors are invited to bring a picnic to hear an informal talk about the history of the land and commoning.
The idea to hold this and other events came from two local artists, Kathrin Böhm and Louis Buckley, who work in close collaboration with the Lee Valley Park rangers.
