Skomer Marine Nature Reserve (MNR) was designated in 1990. The population of Parazoanthus axinellae (yellow trumpet anemone) is an important feature of Skomer MNR. P. axinellae is a Lusitanian (south-western) species near to the edge of its range and may act as an indicator of climatic change. Colonies have been photographed from fixed locations since 2001 and colony growth has been monitored. The purpose of this data capture was to monitor P. axinellae colonies for changes in polyp density and colony area.

The digital camera is mounted on a 20 x 20 cm framer. The number of P. axinellae polyps are counted in each quadrat. Area of the colony: A series of transects are placed through the colonies. Photographs are taken using a 50 x 70cm framer. In 2008 a digital SLR camera replaced the film camera providing high quality images allowing improved photo analysis. The images are analysed by overlaying a 5 x 5cm grid and recording presence/absence of P. axinellae within the grid squares. Density estimates: Close-up photographs are taken using a digital camera.
