In addition, the Polish service men and women based in the area could not return to their homeland, and many settled in North Berwick.
Farmers Bill Mc Nicol of Castleton and Andrew Miller of Bonnington comment on wildlife changes that have been noticed by both of them. In the mid 1970s you could shoot 50 hares in a night at Bonnington but now they are scarce.
Pink-footed geese occur in winter on both farms with increased numbers at Bonnington, perhaps because of milder winters.
They are attracted to winter cereals in the autumn where they may cause some damage but are not regarded as a serious problem.
Bass Rock supports one of the largest breeding seabird colonies in the Forth.
The Bass Rock is woven into the Atlantic gannet's scientific name Morus bassanus.
At the end of the war, there was a chronic shortage of council houses for rent and this was perhaps one of the most serious problems.
There are three Sites of Special Scientific Interest (SSSI) in the parish, and one that straddles both it and Dirleton.
The volcanic plug of North Berwick Law is noted for its botanical interest.
There were several reasons for this shortage, not the least of which was returning servicemen and women; many had married when in the forces and had lived temporarily with relatives or in rented accommodation. There were many cases where a serviceman had married a local girl and had chosen to live here.
In other cases children had arrived so bigger accommodation was required.
Partridges have also declined greatly though they are still present in small numbers on both farms where set-aside has probably helped.
