Vegetation succession and seedbank composition were studied in eleven oldfields with differing crop histories. All the fields had been abandoned from agriculture in the mid-1960's, and some fields are currently receiving periodic management in the form of burning, mowing, and/or removal of exotic species. Oldfield plant composition was found to be most strongly influenced by management history since abandonment. Recently-managed fields had a greater abundance of certain early-successional nonnative species in the herbaceous layer, whereas unmanaged fields contained greater abundances of many later-successional, native perennial herb species. Woody plants showed the most significant response to management. Woody plant densities and species richness were significantly lower in recently-managed fields, whereas unmanaged fields had well-developed sapling and shrub layers. In contrast to the vegetation, the soil seedbanks contained many early-successional, non-native species irrespective of management history. In general, the management techniques are meeting the desired goals of maintaining diverse stages of successional vegetation and reducing establishment of invasive exotic shrubs.
