New Publication: Who eats blueberry crops? Mostly wild boars and blackbirds, and sometimes affecting yield

Blueberry crops are an attractive and easy-to-eat resource for wild vertebrates, which may ultimately decrease crop yields by intense frugivory. In this new study, a part of Javi Jiménez-Albarral’s PhD, we analyse the patterns of blueberry consumption by wild vertebrates in orchards in northern Spain, estimating experimentally the actual effects on crop yield. By using direct observation and camera trapping, we discovered 14 bird and four mammal species entering into orchards to feed on blueberries. Most frugivory was, in any case, accounted for by wild boars and common blackbirds, and a large proportion of consumption corresponded to fallen fruits, directly taken from the ground. Our exclosure experiments demonstrated that vertebrate frugivory may entail significant losses of blueberry crop yield, but these losses are quite concentrated on blueberry early cultivars and in some specific orchards. We suggests some advice for farmers to deal with undesirable effects of frugivores in their blueberry orchards. See the paper in Crop Protection!
