Abstract Context. Mixed forests exhibit greater resistance to pests compared monospecific forests. However, stand-level diversification is challenging for managers. An alternative approach enhance tree diversity at the landscape scale. Objectives. Building on tradition of agricultural bocage, we propose that in a pine plantation broadleaved hedgerows along stands locally increase diversity, while level diversity. According associational concept, both methods should reduce pest damage. Methods. We tested these hypotheses, by counting nests processionary moth (Thaumetopoea pityocampa, hereafter “PPM”) 36 edges adjacent or not hedgerows, landscapes with low high cover. PPM bird and bat predators activities were assessed using acoustic devices. Results. At local level, 42% less abundant taller hedgerows. This reduction was attributed ability hedgerow disrupt host location predation great tit (Parus major), which more active higher cover resulted 72% infestation. Although did significantly affect activity edges, nest abundance decreased increasing species richness consistently natural enemies hypothesis. Conclusions. Planting combined conservation remnants, represents effective promising management strategy mitigating infestation landscapes.
