Bear Down on Bittersweet - December 2018
Asian Bittersweet (Celastrus orbiculatus) is an aggressive invasive woody vine that kills trees by outcompeting for water, strangling trunks, smothering the canopy, and causing damage during wind and ice storms. Invaded woodlands are destroyed limb by limb, tree by tree until there are none standing. Asian Bittersweet seeds are dispersed by birds, yard waste, and
discarded holiday wreaths.
Help NYBG document as much Asian Bittersweet as possible by December 31.
Take photographs of Asian Bittersweet anywhere in New York City and post your findings iNaturalist so they can be added to the NYC EcoFlora Project. For large masses where it is difficult to isolate a single plant, take one photograph every 5–10 feet to cover the entire population. Your observations will show the extent of coverage.
