Seventeen urban food production sites of varying sizes in and around Leeds, UK, selected from an open-source database, were surveyed using pitfall traps to assess the abundance and diversity of epigeal invertebrates (beetles, springtails, and spiders) in relation to soil characteristics (organic carbon, moisture content, pH) and site area; soil productivity was assessed by growing radish (Raphanus sativus) under uniform conditions. The study found no correlation between epigeal invertebrate abundance or diversity and either site area or soil characteristics. The authors state this indicates there is, as yet, no evidence that urban food production sites are too small to draw on ecosystem services delivered by epigeal invertebrates.
