QuestionHave invasive species been a problem for this resource?
Select Options
Unit
Role
ImportanceInvasive species can harm ecosystems whose own species are poorly adapted to the behaviors of the invasive.
Definition

Non-indigenous or non-native species that adversely affect the habitats and bioregions they invade. Effects can include outcompeting native species, predation, affecting habitats, etc.

Central California National Marine Sanctuaries GovernanceCalifornia Rocky Shores Ecosystem HealthYesInvasive species is a massive problem for these habitats. The San Francisco Bay is considered the most invaded aquatic ecosystem in North America as it has over 212 introduced species, consisting mostly of invertebrates such as clams and crabs (SIMoN 2015). The green crab is a particular species causing issues for this habitat.
Great Barrier Reef Marine ParkGovernanceGBR target fishNo
Wakatobi National Park GovernanceWakatobi coral coverNoNo evidence so far of this.
Wakatobi National Park GovernanceWakatobi fish spawningNo
Macquarie Island Marine ParkGovernancePatagonian Toothfish NoThere is no evidence that this stock has been affected by invasive species.
Macquarie Island Marine ParkGovernanceLight Mantled AlbatrossYesFeral cats and rabbits on Macquarie Island were a serious problem for many seabirds. However they were eradicated in 2002; further eradication programs completed by 2012 have eliminated rats and rabbits from the island which has been declared pest-free.

Wakatobi National Park GovernanceWakatobi Green TurtleNoNo evidence found
Galapagos Marine Reserve (GMR)GovernanceGalapagos Sea CucumberNoInvasive species are a problem within the GMR as a whole, however no information found regarding invasive species specific to sea cucumber.
Macquarie Island Marine ParkGovernanceMacquarie Island Royal PenguinYesCats and rats have been known to take the eggs of royal penguins; although pest eradication programs have been successful in recent years

Northwestern Hawaiian Islands (NWHI) Marine National MonumentGovernanceNWHI Trophic DensityNoRecords of invasive species, but no negative impacts reported as yet: Eleven species of shallow-water snapper (Lutjanidae) and grouper (Serranidae) were purposefully intro-duced to the main islands of the Hawaiian Archipelago in the late 1950s and early 1960s. Two snappers, the bluestripe snapper (Lutjanus kasmira) and the blacktail snapper (L. fulvus), and one grouper, the peacock grouper (Cephalopholis argus), are well-established and have documented patterns of colonization along the island chain (Randall, 1987). http://ccma.nos.noaa.gov/ecosystems/coralreef/coral_report_2005/nwhi_ch10_c.pdf
Svalbard Nature ReservesGovernanceSvalbard ShrimpNoFor Svalbard in general, there is considerable concern about the potential threat of invasive species, and the tourism industry recognizes the need to prevent their spread (Evenset and Christensen 2011). However, I have not found literature which documents any issues from invasive species on shrimp in Svalbard.
Heard and McDonald Islands Marine ReserveGovernancePatagonian Toothfish No
Northwestern Hawaiian Islands (NWHI) Marine National MonumentGovernanceNWHI Green TurtleNoFibropapillomatosis disease is considered the primary threat to green turtles - this disease increased rapidly since 1980s, and the prevalence of this disease has been linked to invasive macroalgae (demonstrated strong epidemiological links between disease rates, nitrogen-footprints, and invasive macroalgae (van Houtan et al. 2010)) - NB this paper was contentious!
Great Australian Bight Marine Park (GABMP) (Commonwealth Waters)GovernanceGABMP (Commonwealth Waters) Southern Right WhaleNoThere is no evidence so far of invasive species being a problem for this resource.
Central California National Marine Sanctuaries GovernanceCalifornia Groundfish HabitatYesInvasive species are particularly lethal for juveniles, and somewhat for adults. The native species are not adapted to respond in behavior to invasive species, causing problems as competitors. No species have physiological responses to respond to invasive species (Hamel et al. 2012)
Heard and McDonald Islands Marine ReserveGovernanceLight Mantled AlbatrossNoThere are no invasive species (except for one alien plant species) on HIMI.
Great Barrier Reef Marine ParkGovernanceGBR Green TurtleYesIntroduced species such as rats and dogs can affect turtle nesting and survival of hatchlings (GBRMPA 2014).
Heard and McDonald Islands Marine ReserveGovernanceKing PenguinNoDue to its remoteness and lack of human visitors, there are no reported human introduced invasive species. There is one species of non-native grass (believed to be introduced naturally from another subantarctic island), which does not impact the penguin. However, with no scientific expeditions since 2003/04, it is unknown if there have been recent introductions that may impact penguin populations.
Falkland Islands squidGovernancePatagonian squid (Loligo gahi)No
Svalbard Nature ReservesGovernanceSvalbard KittiwakeNono evidence. For Svalbard in general, there is considerable concern about the potential threat of invasive species, and the tourism industry recognizes the need to prevent their spread (Evenset & Christensen 2011 ).
Cenderwasih National ParkGovernanceCenderwasih coral coverNono evidence
Seaflower MPAGovernanceSeaflower coral reefsNoNone reported
Svalbard Nature ReservesGovernanceSvalbard Polar BearNoFor Svalbard in general, there is considerable concern about the potential threat of invasive species, and the tourism industry recognizes the need to prevent their spread (Evenset and Christensen 2011 ). However, for the polar bear invasive species are not an issue; there are no invasive species which provide competition or negatively affect their food sources.
