“…South African bioinvasions also appear to originate from historical shipping regions such as Europe. Hayden et al (2009) reported that the discovery rate of marine introductions was on the increase within New Zealand with ballast water and ship fouling as major invasive pathways, which is in agreement with our South African findings. Mariculture is recognized as an emerging vector pathway in both Korea and South Africa (Seo and Lee 2009) and as with South Africa, the majority of Australian and South East Pacific bioinvaders are dominated by the annelids, molluscs, crustacea and chordates (Castilla and Neill 2009;Sliwa et al 2009).…”

“…In comparison, New Zealand added 40 introduced and 27 cryptogenic species over a period of 9 years between 1998 and 2007 (Hayden et al 2009). This coincided with the commencement of targeted surveillance aimed at identifying marine introduced species (Hewitt et al 2004) and represents an average rate of 4.4 introduced species and 1.8 cryptogens added per year.…”

“…To date, these have been conducted at both local and pan-regional scales for marine species (Carlton 2003;Castilla and Neill 2009;Fofonoff et al 2009;Hayden et al 2009;Rilov and Galil 2009;Sliwa et al 2009;Wonham and Carlton 2005). Vector types, dispersal pathways, source regions, taxonomic composition, spatial distribution, receiving habitat types, measured impacts and rates of successful introduction have all been investigated (Carlton 2003(Carlton , 2009Hewitt et al 2009;Miller and Ruiz 2009;Minchin et al 2009;Ruiz and Hewitt 2002;Wilson et al 2009;Wonham and Carlton 2005).…”

As recently as 2009 the number of introductions recorded for South Africa comprised 22 marine and estuarine species. This review aims to reassess the diversity and scale of introduced marine and estuarine species in the region. Accurate taxonomic and systematic work, broad review of historical records and new sampling surveys across selected marine habitats conducted by a team of local and international experts has effectively revealed the presence of previously misidentified, overlooked, or new introductions. A total of 86 introduced and 39 cryptogenic species are recognized, increasing known numbers four and twofold respectively within 1 year, although the current assessment is far from fully comprehensive. Additional species were revealed within the historic literature (76%), from surveys conducted post-2005 (11%) and following taxonomic resolution (13%). Temporal analyses confirmed discovery rates were increasing over time. Ship fouling and ballast water were the dominant vector pathways, accounting for 48 and 38% respectively. Spatial analyses revealed patterns of bioinvasion to be significantly higher on the west coast compared to the other coastal regions. Overall, 53% of introductions were concentrated within harbour areas with only 4 opencoast invaders detected at present. Introduced species found in the cool and warm-temperate provinces of the west and south coast mainly originated from the northern hemisphere (65%). In contrast, introductions located in the sub-tropical and tropical provinces of the east coast mainly originated from the southern hemisphere (18%), with the remaining 17% of introduced species being of unknown origin. The research approach described has proven pivotal, contributing massively toward revealing the true scale and patterns of bioinvasion for a developing region within a relatively short period of time.

Aim We examine the regional dominance of California as a beachhead for marine biological invasions in western North America and assess the relative contribution of different transfer mechanisms to invasions over time. Location Western North America (California to Alaska, excluding Mexico). Methods We undertook extensive analysis of literature and collections records to characterize the invasion history of non‐native species (invertebrates, microalgae and microorganisms) with established populations in coastal marine (tidal) waters of western North America through 2006. Using these data, we estimated (1) the proportion of first regional records of non‐native species that occurred in California and (2) the relative contribution of transfer mechanisms to California invasions (or vector strength) over time. Results Excluding vascular plants and vertebrates, we identified 290 non‐native marine species with established populations in western North America, and 79% had first regional records from California. Many (40–64%) of the non‐native species in adjacent states and provinces were first reported in California, suggesting northward spread. California also drives the increasing regional rate of detected invasions. Of 257 non‐native species established in California, 59% had first regional records in San Francisco Bay; 57% are known from multiple estuaries, suggesting secondary spread; and a majority were attributed to vessels (ballast water or hull fouling) or oysters, in some combination, but their relative contributions are not clear. For California, more than one vector was possible for 56% of species, and the potential contribution of ballast water, hull fouling and live trade increased over time, unlike other vectors. Main conclusions California, especially San Francisco Bay, plays a pivotal role for marine invasion dynamics for western North America, providing an entry point from which many species spread. This pattern is associated historically with high propagule supply and salinity. Any effective strategies to minimize new invasions throughout this region must (1) focus attention on California and (2) address current uncertainty and future shifts in vector strength.

“…In the absence of technologies to eradicate or substantially control marine invaders, efforts in New Zealand and elsewhere on marine invasions have focussed on preventing invasion in the first place and identifying which species are most likely to invade, by what routes, and on what impact they might have (e.g., Forrest et al 2006;Hayden et al 2009), and suggesting that rapid-responses should be planned for high-risk invaders, but without actually developing the responses (e.g., Wotton and Hewitt 2004;Forrest et al 2006).…”

New Zealand as a leader in conservation practice and invasion management

New Zealand has played a prominent role in conservation and especially in invasion management. The plethora of 19 th century animal and plant invasions led to much research, beginning in the early 20 th century, on their impacts and how to counteract them. New Zealand particularly became a leader in control and eradication of mammals and in biological control of pestiferous insects and plants. By hosting international conferences on eradicating invasions, and by mounting ambitious, inspirational projects with innovative technologies, New Zealand further increased its influence in this area. The nation has also inspired the world with vigorous, innovative attempts to rescue endemic animal species on the brink of extinction. An impressive New Zealand programme of reserves for conservation of marine species and ecosystems is threatened by the fact that conservation goals and those of commerce and recreation can never fully align. As in other nations with globally important biodiversity, New Zealand has seen disputes between its native inhabitants and European colonists and their descendants over conservation and customary use of this resource. Recognition of a rightful Māori role in these matters, both in the Treaty of Waitangi and recently, greatly surpasses deference given elsewhere to native peoples on related issues, but implementing this role remains challenging.
