ABSTRACT Native and restored forests are increasingly impacted by pests diseases, including large herbivores. While community‐ species‐level impacts of these tree enemies often well‐documented, there is little understanding their influence on finer‐scale eco‐evolutionary processes. We here study the large‐mammal herbivory survival height growth trees in a mixed species restoration planting Australian forest trees, Eucalyptus ovata E. pauciflora , Tasmania, Australia. Common‐garden field trials mixing two were compared adjacent unbrowsed (fenced) browsed (unfenced) plantings. The was exposed to mammal browsing native marsupials, as well feral introduced European fallow deer ( Dama dama ). Each represented open‐pollinated families from 22 paired geographic areas, allowing assessment effects population differences, family variation within each species. In planting, marked reduction variance, observed for both survival. pattern populations also differed between regimes, with significant changes climate relationships involving focal attributes detected. Our results argue major disruption dynamics presence mammalian herbivores, at period life cycle. Importantly conservation face global change, our challenge choice translocation based solely predicted or home‐site current future climates sites, while emphasising need genetic diversity provide resilience biotic abiotic stresses.
