At several refuges managed by the Audubon Society of Rhode Island (ASRI), autumn olive (Elaeagnus umbellata), Asiatic bittersweet (Celastrus orbiculatus), common reed (Phragmites australis) and Japanese honeysuckle (Lonicera japonica) are just a few of the introduced species that dominate fields, encroach on marshes, alter forest edges and threaten riparian corridors. Many introduced species came to North America intentionally. This new gardening season is  the time to practice some prevention. This could save you and land managers hours and money spent removing and controlling invasive species.
