“…In Lake Benella, Victoria, even a 3 month drawdown during summer was not enough to kill all cabomba plants (Dugdale et al, 2013). While long-term persistence of dried out fragments was not tested specifically in the present study, cabomba fragments protected in clumps of stranded vegetation and in moist substrate refugia in Lake Benella survived extended periods of time (Dugdale et al, 2013).…”

“…Also, desiccation rates and survival abilities vary with plant species (Barrat-Segretain & Cellot, 2007;Barnes et al, 2013). Cabomba is known to be relatively resistant to desiccation and can survive a prolonged drawdown (Dugdale et al, 2013), but we lack information on the specific desiccation rates and survival abilities of cabomba when transported overland. Therefore, we cannot accurately predict overland transport distances of viable material under varying environmental conditions.…”

Cabomba caroliniana is a submersed macrophyte that has become a serious invader. Cabomba predominantly spreads by stem fragments, in particular through unintentional transport on boat trailers ('hitch hiking'). Desiccation resistance affects the potential dispersal radius. Therefore, knowledge of maximum survival times allows predicting future dispersal. Experiments were conducted to assess desiccation resistance and survival ability of cabomba fragments under various environmental scenarios. Cabomba fragments were highly tolerant of desiccation. However, even relatively low wind speeds resulted in rapid mass loss, indicating a low survival rate of fragments exposed to air currents, such as fragments transported on a boat trailer. The experiments indicated that cabomba could survive at least 3 h of overland transport if exposed to wind. However, even small clumps of cabomba could potentially survive up to 42 h. Thus, targeting the transport of clumps of macrophytes should receive high priority in management. The high resilience of cabomba to desiccation demonstrates the risk of continuing spread. Because of the high probability of fragment viability on arrival, preventing fragment uptake on boat trailers is paramount to reduce the risk of further spread. These findings will assist improving models that predict the spread of aquatic invasive macrophytes.

“…Currently C. caroliniana is naturalized in the United States, Canada, Greece, Japan, Malaysia, the Netherlands, Australia, and China (Ørgaard, 1991;Oki, 1992;Les and Mehrhoff, 1999;Zhang et al, 2003;Wilson et al, 2007;Matthews et al, 2013). Once introduced, C. caroliniana causes a range of ecological (Mackey and Swarbrick, 1997;Hogsden et al, 2007;Wilson et al, 2007) and socio-economic impacts (Mackey and Swarbrick, 1997;Dugdale et al, 2013).…”

a b s t r a c tCabomba caroliniana is a submersed aquatic macrophyte that originates from the Americas and is currently invading temperate, subtropical, and tropical freshwater habitats around the world. Despite being a nuisance in many countries, little is known about its ecology. We monitored C. caroliniana populations in three reservoirs in subtropical Queensland, Australia, over 5.5 years. Although biomass, stem length, and plant density of the C. caroliniana stands fluctuated over time, they did not exhibit clear seasonal patterns. Water depth was the most important environmental factor explaining C. caroliniana abundance. Plant biomass was greatest at depths from 2-4 m and rooted plants were not found beyond 5 m. Plant density was greatest in shallow water and decreased with depth, most likely as a function of decreasing light and increasing physical stress. We tested the effect of a range of water physico-chemical parameters. The concentration of phosphorus in the water column was the variable that explained most of the variation in C. caroliniana population parameters. We found that in subtropical Australia, C. caroliniana abundance does not appear to be affected by seasonal conditions but is influenced by other environmental variables such as water depth and nutrient loading. Therefore, further spread will more likely be governed by local habitat rather than climatic conditions. Crown

“…The method of water drawdown, which is the lowering of a waterbody to expose submerged vegetation to the air, is a potential method to reduce C. caroliniana growth and development (Dugdale et al, 2013) (Table 3). Trials have shown this method has had positive results for reducing C. caroliniana growth, although the effect is only temporary and is only applicable in waterways that can be structurally managed to reduce water flows and control the water level (Dugdale et al, 2013). Research by Dugdale et al (2013) suggests that sediments will also need to be completely dry for this method to be successful at eradicating C. caroliniana infestations.…”

Cabomba caroliniana [A. Gray] (Cabombaceae), also known as Carolina fanwort, is a native of South America which has now become a serious invasive threat to aquatic systems across the world. Its capacity to inundate a water column with active fragments and seeds makes the containment and management of C. caroliniana a challenging task and an ecological and economic necessity. Previous and current management efforts have been largely focussed on biological control, drawdown methods, herbicide application, manual removal, shading and the use of a concentrated urea solution. Although these methods have shown some success in reducing large infestations, they are generally considered to be unreliable when used alone since they are unable to contain or reduce the species in the long term with a single‐use treatment protocol. It is feared that, without effective, improved and integrated management strategies, C. caroliniana will continue to invade aquatic ecosystems beyond its already wide current distribution, thus causing increased global economic and environmental damage. This review will therefore explore the biology and distribution of C. caroliniana and examine the current and previous attempts for its global management. It will also evaluate the most successful current treatments and clarify where research efforts are urgently needed for the improved long‐term extirpation of this aquatic invader.
