Pink pepper from Piper nigrum is distinct from the more-common dried "pink peppercorns", which are actually the fruits of a plant from a different family, the Peruvian pepper tree, Schinus molle, or its relative the Brazilian pepper tree, Schinus terebinthifolius.
Schinus terebinthifolius (Brazilian Pepper, family Anacardiaceae), native to South America but introduced and invasive in many tropical and subtropical areas
Lophyrotoma zonalis from Australia has been considered for release against Melaleuca quinquenervia in Florida, and Heteroperreyia hubrichi against the Brazilian Peppertree, Schinus terebinthifolius.
Threats to the plant include habitat degradation and destruction by feral pigs and goats and non-native plants such as Ageratina riparia, Erigeron karvinskianus, Grevillea robusta, Melinis minutiflora, Rubus argutus, and Schinus terebinthifolius.
Species such as the strawberry guava (Psidium cattleianum), and christmasberry (Schinus terebinthifolius) have spread across wide areas, competing with native species and altering the natural ecosystem.
