The veteran rocker has joined forces with neighbours in West Wittering to fight to keep the 9.5-acre field as a haven for rare plants and insects, including green-winged orchids.
He has already bought local woodland to protect colonies of bats.
Retired oil company executive Peter Dawson, 86, a neighbour of Richards for 30 years, is spearheading the campaign to preserve the meadow.
“It is vital Redlands meadow gets protected by law otherwise it could be cultivated for agriculture using chemicals or it could even be sold for property development,” he said.
“We love Keith as a neighbour because he is completely dedicated to protecting the wonderful countryside we all enjoy so much. He may be a rock star but he is the most down to earth man I know.”
If the campaign is successful the meadow will be reclassified as a local nature reserve and ownership transferred or leased to West Sussex County Council.
