In such algae, the use of attached algal turfs, wherein the simple algae all or most cells are photosynthetic, demands critical attention to wave surge motion. We call them coral reefs because their three-dimensional structures are built by stony coral animals, which produce limestone as they grow ever upwards towards the sun. Canopy-forming brown algae (kelps and fucoids) that provide habitat structure on temperate rocky reefs increasingly are replaced by assemblages of low-lying and pervasive turf algae, driving concerns that these shifts represent a stable degraded reef state. DEFINITIONS OF TURFS The term ‘turf’ is primarily used in agriculture to describe lawn-like landscapes that are low lying (mm to cm tall) and are defined as a layer of grass plus roots and associated earth in grasslands (Webster and Oxford Dictionaries). The use of standardised classifications, or operational definitions, is essential if dif- ferent researchers are to measure and compare similar entities.
