=== Agriculture ===
The study of waterlogged macrofossils through a series of wells throughout the abandoned civilisation resulted in key evidence of animal stabling, hay meadows management, and the use of [[heath]] resources (such as heathers, gorse, and heathland grasses). The most abundant crops that were found in the area are ''Capsella bursa pastoris'', ''Chenopodium album'', ''Polygonum aviculare'', ''Stellaria media'' and ''Urtica urens'', ''Fallopia convolvulus'' and ''Sisymbrium''. The use of new oil crops and grassland management is evident that the agricultural upheaval changes were related to those that provide food to livestock rather than providing food to the population of the civilisation. The development of the land represents a major change in the social organisation and settlement form. This is evident in the ample earthwork or large artificial banks of soil. Between the [[Hampshire]] chalk downs and alluvium-rich flood plains of the Thames valley, the civilisation is on a gravel terrace of the [[River Kennet]], a major tributary of the Thames. This has left beneath its thin much later organic topsoil, feet of tertiary clay and sand.  If ploughed the result is a "well-drained brown-earth soil" which, unirrigated, and without high fertilisation, yields low cereal returns. It is traditionally often cleared as pasture, orchards or kept as bramble-rich woodland for hogs and game. Palaeoenvironmental studies of the Early Iron Age at this site expose largely cleared land. Development of the heath from this time is evidenced by pollen analysis.<ref name="Agricultural innovations at a Late Iron Age oppidum">{{cite journal |last1=Lodwick |first1=Lisa A |title=Agricultural innovations at a Late Iron Age oppidum: Archaeobotanical evidence for flax, food and fodder from Calleva Atrebatum, UK |journal=Quaternary International |year=2017 |volume=460 |pages=198–219 |doi=10.1016/j.quaint.2016.02.058 |bibcode=2017QuInt.460..198L |s2cid=62815053 |ref=1|doi-access=free }}</ref>
