- The beach strandline is just as much a wildlife habitat as a woodland or wildflower meadow, and every bit as diverse and interesting. It has a dynamic nature, changing every day as organic debris from the sea is deposited on the beach to be gradually broken down by the strandline inhabitants; sometimes the whole strandline is buried in sand or shingle or submerged by storm waves.2015, Steve Trewhella, Julie Hatcher, The Essential Guide to Beachcombing and the Strandline, Wild Nature Press, →ISBN, page 235:
