In 2015 Skomer Marine Nature Reserve changed designation to Skomer Marine Conservation Zone (MCZ). Skomer Marine Nature Reserve (MNR) was designated in 1990.


Grey seals are a protected species of conservation importance, which live and breed in the Skomer MNR. The West Wales population is the largest in SW Britain and is a feature of the Pembrokeshire Marine Special Area of Conservation (SAC).


The purpose of this data capture was to monitor the number and survival rate of seal pups born in the MNR.

Lineage

The pups are recorded from birth through to their first moult using the "Smith 5-fold classification system" (Poole 1996). Reason for death is recorded if possible. Additional behavioural observations are recorded for the Island seals (Full method described in 'Grey Seal Monitoring Handbook' Poole 1996).


Regular recording began on Skomer Island in 1974 and surveys have been completed annually since 1983. From 1992 onwards a standard protocol has been adopted to record the pupping success on both the island and the mainland each year. Records of identifying features e.g. scars are recorded.


More detail will be available in the Marine Monitoring Standard Operating Procedures (SOPs), available to request from NRWs internal Document Management System (DMS).
