This dataset contains the results of a survey carried out in 2007 to investigate whether P. planicrurus was still present in the area. Monitoring of this feature is ongoing and is repeated on a yearly basis. The purpose of this data capture is to confirm the continued presence and monitor the population of this scarce amphipod species at Pwllheli, repeating work carried out in 2004.

The species is found by finding the appropriate habitat, making a small pool of water in the shingle and then looking for amphipods swimming in the water. This was done at irregular intervals along the shore. The survey is repeated regularly.
