Biodiversity data collection included standard transect walks of 100 m to record the abundance and activity of butterflies, as well as numbers of Assassin bugs and Nephila spiders within a 5 m x 5 m box in front of the recorder. At four points along the transect, separated by 20 m, we also recorded understory flying invertebrate abundance and predation. Clear plastic sheets smeared with glue were used as sticky traps, suspended 40 cm above the ground and facing south, to collect understory invertebrates. Sticky traps were collected after 24 hours. Sticky traps were photographed to allow later recording of invertebrate abundance. Cards with 6 dead meal worms attached and hung on palm trunks next to sample points were used to assess predation, by recording removal over 24 hours. Environmental data collection methods included visual inspection of plots to record the cover of different crop types and using handheld GPS units to record plantation boundaries and the size of plantations. At the same four sample points used to set pitfalls and sticky traps, we also made direct measurements of vegetation, palm and soil characteristics. These included field readings of canopy openness using a convex spherical densiometer, direct measures of vegetation height and cover (into categories by eye within a 3 m x 3 m area), and field measures of soil pH and moisture using a Suplong probe. We also scored height, health, % epiphyte cover on the trunk, and level of herbivory by eye on the closest palm to each point. We also dug small soil pits to assess leaf litter depth and then used a standard 10 cm deep and 5 cm diameter tube to collect soil samples. We also conducted a Visual Evaluation of Soil Structure (VESS) survey to measure the depth of soil horizons and associated characteristics, following standard methods. Social data were collected through a mixture of telephone and face-to-face interviews with smallholders, at a time convenient to the smallholders. Some telephone interviews were necessary owing to the impacts of COVID. Ethical permission for interviews was gained from the University of Cambridge Department of Psychology ethics board before work took place, no information was withheld from participants and full written consent was obtained in advance. On return to the lab, soil samples were weighed wet and then dried to a constant weight, allowing water content and soil compaction to be calculated. Sticky trap photos had insects counted and identified to order-level. Data were entered digitally by field teams and returned to the University of Cambridge for quality and error checking, and to ensure a standard format.
