Foreman Michelle's head torch cast a strong beam of light that cut through the darkness in Walpole Park. Her team of four plunged their shovels into bottomless piles of woodchip. The woodchip was to be spread evenly around the bases of oak trees along a path - or at least that was what the team believed in.

Two floodlights and five head torches seemed like a glimmer against the pitch-black night. But Foreman Michelle could see very well whether Alan and Sevan covered the tree roots with the standard 20 cm layer of mulch and whether the amount of woodchip that Steph and Kash loaded each time into the wheelbarrow didn't exceed the acceptable health & safety regulations.

After hitting the target of 8 trees mulched, Michelle decided it was knocking-off time. The team returned the tools to the storage, cleaned the wheelbarrows and set off to their homes for rest as the next day another work shift awaited at Gunnersbury Park.
