Non-native invasive species have major impacts on landscapes worldwide, but their effects in urban areas are not well documented. We quantified the response of naturally regenerating vegetation along an urban creek to removal of the invasive shrub Lonicera maackii (Amur Bush Honeysuckle). Over the 5-year study, species richness more than doubled. Most new plants were native, disturbance-adapted, early successional species. Trend analysis of function traits revealed annuals that rely on seed dispersal by wind or externally on animals were significantly overrepresented among new plants in comparison to their proportion in the countywide species pool. Increased species richness did not result …
