A digital media company has been working with the National Trust to help conserve the South Downs.

Seven staff from Brighton-based Worth Media donated their time to "scrub-bashing" - returning an area to scrubland.

Many species can only survive in grassland and would become extinct if it disappeared.

The day of volunteering also provided the team with a chance to get out of the office and do something different.

Angela Galvin, interactive designer, said: "It was great to get out in the fresh air, with fantastic views over the Downs, and feel like we were doing something worthwhile.

"Everyone got into the spirit of it and worked together. At the end of the day it was amazing to see what a difference we'd made."

Amanda Cooton, who coordinates the company's volunteer activities, said: "The day was a big success and it gave us the chance to give something back into the community. More companies should get involved."

Worth Media, whose customers include the departments of health and trade and industry, is working towards the Community Mark, which recognises the work of small and medium-sized businesses in their communities.

Lime, the Brighton-based marketing agency, was the UK's first small business to be awarded the kite mark.
