Dominance by the introduced tree Rhamnus cathartica (common buckthorn) may limit aboveground carbon storage in Southern Wisconsin forests

▶ Forests dominated by Rhamnus cathartica stored half the biomass of those dominated by native trees. ▶ Growth of R. cathartica declined relative to native trees with increasing size. ▶ Allometric models provided for biomass, height, leaf biomass, and fruit biomass of R. cathartica.
