Cabomba caroliniana A.Gray (cabomba) is an invasive aquatic species causing serious environmental and socio-economic impacts. In particular, cabomba has a tendency to create large monospecific stands once introduced and appears to negatively affect native macrophyte diversity.
Experiments have shown that cabomba, when cultured in isolation, grew significantly faster than any of the other macrophytes tested. However, competitive superiority over other macrophytes declined with increasing pH. Contrary to this, cabomba seemed to be a weak competitor in co-culture and few macrophytes showed signs of being affected by negative competitive interactions with cabomba.
The reduction in growth performance at pH >7.5 and the fact that cabomba appears to be a weak competitor means that cabomba might not be able to establish everywhere and displace other plants. This weakness of cabomba could potentially be exploited in future management and rehabilitation efforts.
