Abstract

Sawtooth oak (Quercus acutissima Carruth.), native to eastern Asia, is widely planted in the eastern United States as a source of food for wildlife (especially turkeys) and as a landscape tree in developed areas. Spontaneous reproduction of sawtooth oak outside of cultivation has now been confirmed for Alabama, Louisiana, Maryland, Missouri, Mississippi, North Carolina, Pennsylvania, and the District of Columbia. A complete description and an illustration are provided. Feral populations of sawtooth oak are mostly confined to open, often disturbed areas, and it spreads very slowly, apparently due to limited dispersal of the acorns. Planting of large stands of Quercus acutissima in natural areas or revegetating areas for wildlife food is likely to result in the establishment of this exotic species and its spread into adjacent habitats, but the use of sawtooth oak as a landscape tree in developed areas usually poses much less danger of escape. Quercus acutissima Carruth., nativo del este de Asia, está ampliamente cultivado en el este de los Estados Unidos como fuente de alimento para la fauna salvaje (especialmente pavos) y como árbol de paisaje en áreas desarrolladas. Su reproducción espontánea fuera de cultivo se ha confirmado ahora en Alabama, Louisiana, Maryland, Missouri, Mississippi, North Carolina, Pennsylvania, y el Distrito de Columbia. Se aporta una descripción completa y una ilustración. Las poblaciones silvestres de Quercus acutissima están mayormente confinadas a áreas abiertas alteradas, y se expande muy lentamente, debido aparentemente a la dispersión limitada de sus bellotas. El establecimiento de grandes plantaciones de Quercus acutissima en áreas naturales o áreas de revegetación para alimento de la fauna salvaje es probablemente la causa del establecimiento de esta especie exótica y su expansión en los habitats adyacentes, pero el uso de Quercus acutissima como árbol de paisaje en áreas desarrolladas tiene mucho menos peligro de escape.
