. 1. Tree harvesting, an anthropogenic disturbance, and natural disturbances, such as avalanches, windstorms, fires, and floods, drive forest reestablishment. Chrono‐sequential changes in plant communities as well as reforestation caused by harvesting and natural disturbances can affect forest faunal assemblages. 2. The effects of reforestation age, from recently harvested to old growth between 1 and 178 years old, on moth assemblages were examined for two types of reforestation: plantations and natural regeneration. 3. In total, 7848 individuals representing 579 species of moths were collected using black lights and then identified. In plantation forests, species richness and abundance responded unimodally to succession age, whereas in naturally regenerated forests, species richness and abundance did not significantly respond to succession age. In addition, the community structure of moth assemblages varied greatly in relation to succession age in both reforestation types. 4. These findings suggest that if the diversity of moth assemblages changes within and among forest stands of different successional stages, forest stands can provide habitat for unique moth assemblages. Thus, intentional forest management may enable the maintenance of greater moth diversity within a heterogeneous landscape or region. Various land‐use practices, such as old growth forest conservation and short‐length harvests, associated with forest types at the level of the forest stand could result in forest mosaics at the landscape or regional scale.
