Three one-gram samples were taken using a riffle divider, separated into taxa and non-seed debris and weighed. The weight of each species is expressed as a percentage of the weight of the samples as a whole. Viability tests were carried out on species recorded as ‘frequent’ at the site using standard MSB methodologies (Davies et al., 2015a). Viability % = (G+F+A)/X x 100, where G = number of germinated seed, F = number of fresh ungerminated seed, A = number of abnormal seedlings, X = number of seed sown (excluding empty and infested seed).
