Channel Islands

The Royal Observer Corps did not extend to the Channel Islands. However after the war Civil Defence was reactivated on the Channel Islands with CD HQ's on Jersey, Guernsey and Alderney utilising former German military bunkers. While Civil Defence was abolished on the mainland in 1968 it remained active in the Channel Islands and is still fully operational today taking part in national and international exercises.

A network of protected monitoring posts was established on Jersey and Guernsey performing a similar function to those on the mainland and using some of the same equipment. These posts were also located in former German military bunkers. They report to their respective CD HQ's which perform the same role as mainland ROC group HQ's. These monitoring posts are still active although in peace time use unmanned monitoring equipment which sends data back to the CD HQ's. The monitoring instrument is a Mini Instruments 7-40, measuring temperature, wind speed, wind direction and radiation levels from sensors and detectors mounted on the roof. These days the nuclear threat is more likely to come from an accident at the nuclear waste reprocessing plant at Valognes near Cherbourg than from nuclear weapons. In a time of major alert or war they can be fully manned and have sleeping and eating facilities available.

On Guernsey there are three monitoring posts at Vale, St. Martin and Torteval with a forth post recently established within the CD HQ on Alderney. All four posts send data back to Guernesy CD HQ at La Corbinerie.

On Jersey there are three underground monitoring posts, all located in ex German bunkers sending data back to Civil Emergency Centre in Trinity Road, St. Helier. They are at are at Gouray (714504), Egypte (663557) and St. Ouen's Church (579533).
