STAFF from Catterick Sunday Market, which attracts more than 15,000 visitors every week, have been planting 8,000 trees on the customers' behalf for more than two years.

The tree-planting, at nearby Brough Park, is part of the market's campaign to be more environmentally-friendly.

Ten trees have also been planted on behalf of the Teenage Cancer Trust.

The market, which has more than 200 stalls each week, is giving shoppers a chance to choose the name of the forest.

Each year, the forest will have a different name, to reflect the changing nature of the market, which is campaigning to be named the National Market Traders Federation's most environmentally-friendly market in the UK.

Greville Worthington, who set up the market in 1992 and still owns it, said: "We planted most of the trees two years ago, but we did not want to publicise the carbon offsetting project until they had had a couple of seasons' growth.

"They are starting to look like trees and planting is ongoing. There are visual similarities between the mass of trees and the crowds of punters we get on market days."

The winner of the competition to name the forest will receive a guided tour of the site, and a certificate.
