Mavis Halliday, who was 19 when war was declared in September 1939, was presented with her award by Rev David Greenwood at Garstang United Reformed Church on Sunday.
Mavis was working at Burtons, the tailors, in Bolton when war broke out, near where she grew up in Kearsley.
In an effort to do her bit for the country, she went to work in the munitions factory in Risley, where she helped to make detonators for bombs and shells.
But she was only able to stay there a few months because the gunpowder made her ill with a condition known as yellow powder fever.
Instead, she decided to join the Land Army, and was posted to Abergavenny. There, she was trained in pest control, becoming a 'rat catcher', although she actually trapped all sorts of animals classed as pests, including rabbits and squirrels. As a rat catcher, Mavis protected the crops that farmers were working hard to grow in order to feed the population and avoid importation.
Mavis stayed in the Land Army, working on farms in South Wales, until she was demobbed shortly after VE Day in June 1945.
Mavis's daughter-in-law Joanne said during the service: "This is a very special day for Mavis; and David, John and I are pleased and proud to be here to see her presented with her Land Army medal in this lovely church, where you have all made her so very welcome.
"After the war the men and women who had served in the Forces received medals, but there was no official recognition for the girls of the Land Army and Timber Corps.
"Many people thought that the fact that the Land Girls and Lumberjills received no recognition was an injustice, and campaigned over a number of years for the omission to be rectified.
"Finally, last December, over 60 years after the war ended, the government announced that medals would be awarded and invited women who had served in both organisations to apply.
"Apparently they received 29,000 applications from all over the world, which is amazing when you think that there were 80,000 Land Girls and Lumberjills in total and the very youngest of them will be almost 80 years old now."
Rev Greenwood added that it was a very proud and special occasion.
