In keeping with many areas of the Scottish Iron Age the excavation site assemblages demonstrate that the inhabitants of South East Scotland utilised a range of resources from the land and sea. A range of coastal resources were exploited, including fish, crustacea and molluscs. Seaweed was used as fertiliser. Due to the exceptional bone preservation at Broxmouth, where 26,000 bone fragments were recorded, we can see that the inhabitants had cattle, sheep, goat, pig, horses and dogs. There is the possibility that pigs were not bred but brought to the site as tribute. The high incidence of lambs in the bone assemblage raises the possibility that sheep dairying formed part of the economy.
Agricultural practices included the growing of barley and wheat. Crop processing is evident from charred grains and the various forms of querns found across the region including rotary and saddle querns. Many of the cobbled stone tools would also have been used in food production and processing. The crude, local coil-built, pottery would, of course, been the utensils for cooking and eating.
