Pollen analysis shows that widespread clearance of the beech forests took place in the early Bronze Age. Cereal pollen have been found at Porsguen, Plouescat, for example. Domestic animals included sheep, goats and cattle, but hunting may have still provided a lot of meat. La Roche, Videlles, has still 60% wild animals among the animal bones, but it is not clear if this is typical. Carbonised remains of naked wheat and barley have been found at Plounéour-Trez, hazelnuts and acorns were eaten as well. Flint still formed an important part of the tool inventory.
