Statement

Environmental and social data were collected in a series of field campaigns, led by researchers from Universiti Putra Malaysia (UPM) and supported by University of Cambridge. Environmental data collection methods included visual inspection of plots to record cover of different crop types, and using handheld GPS units to record plantation boundaries and size of plantations. At four points distributed across the plantation and separated by 20m, 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 3m x3m 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 measured leaf litter depth. Social data were collected through face to face interviews with smallholders, at a time convenient to the smallholders. Ethical permission for interviews were 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. 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.
