Information within the GISD and CABI ISC databases is compiled from an array of sources including scientific papers and regional species databases and is reviewed by international expert contributors (GISD, 2016; CABI ISC, 2016). In Fig. Guadeloupe was assigned the same number of treaties as France. Correspondence: Anna J. Turbelin, Department of Geography, King's College London, Strand, London WC2R 2LS, UK. are the main pathways for unintentional introduction of IAS across regions, followed by ‘Natural dispersal’ (ND) (natural disasters, floating debris, use of human‐modified waterways, etc. See the top management priorities. Both state and interstate aquatic invasive management plans have been growing in efforts to limit their spread. The threat of alien invasive insect and mite species to food security in Africa and the need for a continent-wide response. Keywords used (including plural variants) were: ‘alien’, ‘invasive’, ‘exotic’, ‘non‐indigenous’, ‘non‐native’, ‘pest’ and ‘introduced species’. As its name suggests, the emerald ash borer infests ash trees, killing them within one to four years. Benign components of their original habitats, invasive species include plants, mammals, birds, fish, amphibians, reptiles, arthropods, mollusks, and plant and animal diseases. As many as 10 trillion quagga and zebra mussels are in the Great Lakes today. Dominant pathways for species invasions are similar across different regions. Although countries are concerned about the introduction and spread of IAS within their legal boundaries, not as much attention is given by originating countries to preventing the egress of species, unless the species has known public health impacts. Distribution modelling of an introduced species: do adaptive genetic markers affect potential range?. Plants, mud, and animals such as mussels can often cling to the exterior of boats and boat trailers, while water contained in ballast tanks and other boat compartments can also inadvertently spread alien species. These species affect areas within national parks, but they travel to and from adjacent properties such as private, state, federal, and tribal lands. These exceptions reinforce the influence of colonization and trade on invasion patterns. The dominance of plants and arthropods in the GISD (2016) and CABI ISC (2016) databases is unsurprising (Table 3). France is followed by the UK, the Netherlands and Germany each with 24, and Spain and Italy with 23. The majority of African countries, the Arabian Peninsula and Asia (India, China) have no data or only low‐relevance (maximum relevance score 1 or 2) legislation/regulations. Global variation in the availability of data on the environmental impacts of alien birds. The metallic green beetle native to Asia and Eastern Russia was first discovered in the U.S. in 2002 and has since spread to 25 states. Exceptions in Africa include South Africa, with a high SInv = 208 (SNat = 100) (Fig. As emphasized in Fig. Predicting invasion hotspots in the Arctic marine realm. Missouri enacted HB 6, which appropriates money to the Fisher Delta Research Center in order to fund a public-private partnership for the control of Asian carp in Missouri. Economic impacts can be huge. The European Environment Agency (EEA, 2012) has also developed indicators, including the cumulative number of invasive species in Europe since 1900, awareness of IAS and a map of the ‘worst’ species to monitor progress towards Target 9. Endozoochory by mallard in New Zealand: what seeds are dispersed and how far?. Federal Issues | Environment and Natural Resources, The Threat of Terrestrial Invasive Species, state and interstate aquatic invasive management plans, National Invasive Species Information Center State Laws and Regulations, National Invasive Species Information Center’s partial listing, Asian Carp Regional Coordinating Committees, Center for Invasive Species Research at the University of California-Riverside, Quagga-Zebra Mussel Action Plan for Western U.S. Annual Review of Ecology, Evolution, and Systematics. For both (a) and (b), the scale increases logarithmically. As might be expected, those countries with greater numbers of IAS have more targeted regulations/legislation specifically dealing with IAS, with a maximum relevance score ≥3 (Fig. Recent trends in non‐native, invertebrate, plant pest establishments in Great Britain, accounting for time lags in reporting. Any queries (other than missing content) should be directed to the corresponding author for the article. At least 10 states are considering legislation that creates either aquatic species funds or management programs—Alaska, California, Massachusetts, Michigan, Montana, New Hampshire, New Jersey, Nevada, Oregon and Vermont. See additional information for Figs. Our study supports previous research highlighting economic development, with its associated international trade and globalization, as key drivers of IAS introduction (Vilà & Pujadas 2001; Meyerson & Mooney, 2007; Westphal et al., 2008; Pyšek et al., 2010). This increase in algae also causes botulism outbreaks that kill fish and aquatic birds. (2008) notes that two‐thirds of research efforts on the African continent are accounted for by South Africa. Invasive species are species that are not native to Minnesota and cause economic or environmental harm or harm to human health. lobata). The total number of IAS recorded in the two databases is More than 6,500 nonindigenous species are now established in the United States, posing risks to native plants, animals, microorganisms, valued ecosystems, and human and wildlife health. Lists of harmful alien organisms: are the national regulations adapted to the global world? Plants identified in these lists cannot be sold, transported, or propagated within the state unless authorized by permit. Invasive carp not only out-compete native aquatic wildlife, but they can drastically alter the food web and overall aquatic system by impacting fish, invertebrate and plant communities. the ability to search documents using keywords). 4a) introduction of IAS. Intentional introductions of fish through AQ vary from 47% of recorded invasive fish in North America to 81% in Africa. 2010). Locate an invasive species event in you state or county. South Africa, China, India, Brazil) have generally received the most IAS, but also that small tropical and sub‐tropical islands in particular have high numbers of IAS per km2. \"Invasive species\"they may not sound very threatening, but these invaders, large and small, have devastating effects on wildlife. Additionally, numerous states have enacted laws addressing such threats. DEC received 96 application and awarded approximately $2.8 million from the New York State Environmental Protection Fund (EPF) to 42 projects.$594,464.38 was awarded to eight Aquatic Invasive Species Spread Prevention projects. Currently regulated by federal law and present in Maryland 3. Invasive species on the watch list have been identified as posing an immediate or potential threat to Michigan's economy, environment or human health. This database was thus considered to be the most comprehensive available, having both ease of access and good search functionality (e.g. The emergence of prioritisation systems to inform plant health biosecurity policy decisions. Figures S2–S5 show chord diagrams, broken down by organism type, for the number of IAS that ingress/egress to a geographical region intentionally/unintentionally. The proportion of each country's IAS (excluding overseas territories) introduced unintentionally ranges from 25% to 100% of the total IAS recorded in that country, with 63% of countries globally having a greater proportion of species introduced unintentionally. (1) in main text) the # of international treaties per country (based on ECOLEX, 2016), and the number of IAS per country SInv) divided by that country's land area (A) in km2. State Programs Department of Natural Resources and Conservation Montana Invasive Species Council (MISC) The MISC is a statewide partnership working to protect Montana’s economy, natural resources, and public health through a coordinated approach to combat invasive species. Table S1 in the Supporting Information gives the terms used in the GISD and CABI ISC databases with respect to species occurrence and invasiveness. China, India, Brazil) seem to be the main recipients of IAS, along with islands that are former European colonies and which would have long histories of repeated species introductions or increased ‘introduction effort’ (Lockwood et al., 2005) (Figs 1 & 3). For a detailed compilation of state invasive species laws, visit the National Invasive Species Information Center State Laws and Regulations site. Similar trends are observable in the five central Asian countries, which have relatively low numbers of recorded IAS (4 < SInv < 13) (Fig. Such invasive species can be introduced intentionally as crops, livestock, sport fish or pets, or unintentionally, such as by “hitchhiking” on ships. Minnesota Sea Grant (MNSG) was a conference sponsor, and Extension Educator Doug Jensen co-chaired the conference, hosted an exhibit and presented.

Montana Invasive Species Invasive species include plants, animals, and microorganisms that are nonnative to our ecosystem and cause harm to natural and cultural resources, the economy, and human health. Both islands and some highly developed New World countries (e.g. Known to have significant economic impacts on agricultural ecosystems, public infrastructure or natural resources, including impa… Her research interests are in biogeography, global ecology with a focus on interactions between invasive species and natural hazards. The total number of IAS with native range information recorded in the two databases (S NatT) is 1140. The invasive native range (INR) for each IAS was also determined, when available; this refers to the native range (countries of origin) of each IAS based on information in the GISD and CABI ISC. Wilson et al., 2007; Pyšek et al., 2008). Functional feeding traits as predictors of invasive success of alien freshwater fish species using a food-fish model. A spatio-temporal, landscape perspective on Acacia dealbata invasions and broader land use and cover changes in the northern Eastern Cape, South Africa. Once an invasive species is introduced and becomes established, causing damage or crop losses, our normal IPM practices may prove ineffective. Reduced access to these sites can slow growth and increase mortality of native turtles. ‘Trade’ (TRA) (pet/aquarium trade, live food trade, online sales, industry, etc.) and you may need to create a new Wiley Online Library account. The IAS with the greatest recorded international presence, per organism group, are listed in Table 3. Of the 1517 recorded IAS, 39% were introduced only intentionally and 26% only unintentionally, 22% both intentionally and unintentionally, while 13% had no information available. Furthermore, the sheer size of some carp has been known to injure boaters—silver carp often jump out of the water when disturbed. As shown in Fig. Numerous states have developed action plans for preventing and controlling invasive mussels, such as the Quagga-Zebra Mussel Action Plan for Western U.S. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage. The number of recorded IAS (SInv), the number of native invasive species per country (SNat) and Κ for each country are given in Table S3. The five territories with the lowest Κ (−5.6 ≤ Κ ≤ −5.4) are Mongolia, Afghanistan, the Democratic People's Republic of Korea, Azerbaijan and Kyrgyzstan. Philosophical Transactions of the Royal Society B: Biological Sciences. Currently regulated by the state of Maryland or a local jurisdiction within Maryland 2. Pimentel et al., 2005; Stohlgren & Schnase, 2006; Kettunen et al., 2009; Ricciardi et al., 2011), making species invasions an environmental issue of great global significance. 3 we present the results for our IAS asymmetry index (Κ, equation 1). Measure and Reduce the Harm Caused by Biological Invasions. Global distribution patterns provide evidence of niche shift by the introduced African dung beetle Digitonthophagus gazella. the USA, Australia, New Zealand) have a medium to high positive asymmetry index In fact, the federal government deems Asian carp to be the most acute aquatic invasive species threat facing the Great Lakes. Though the average lifespan of quagga and zebra mussels is only five years, each one will produce approximately 5 million eggs during this time. Overseas territories have been allocated the same number of international treaties as their sovereign state. IAS records for which information on the INR was not available were excluded from the INR analysis. Additional Supporting Information may be found in the online version of this article: Table S1 Global Invasive Species Database (GISD, 2016) terms used in their categories for species ‘occurrence’, ‘status’ and ‘invasiveness’ [A,B,C] and CABI Invasive Species Compendium (CABI ISC, 2016) used for their category terms in ‘absence’, ‘presence’ and ‘species’ [D,E,F]. is the number of species native in a country but invasive elsewhere (SNat) divided by the total number of recorded IAS in the databases for which information about invasive native range was available All other information on the legend, circles and mapping source is the same as for Fig. Many states are seeking to limit the spread of these invasive nuisances, while other states are proactively attempting to thwart the introduction of mussels in their waters. Here we report on patterns of (1) invasions and IAS native range, (2) pathways and (3) policy response. Economic and environmental damage from invasive species in the Great Lakes Basin is already estimated at $5.7 billion per year, and both commercial and sport fishing in the Great Lakes Basin have suffered losses estimated at $4.5 billion. This contrasts with many Western European countries with a negative to zero asymmetry index (2015) mapped the global exchange and accumulation of alien plants and Essl et al. Short-term responses to warming vary between native vs. exotic species and with latitude in an early successional plant community. These turtles can get quite large (10-12”) and are notoriously aggressive, and can bully native turtles out of basking sites, a critical resource for these reptiles. These species either have never been confirmed in the wild in Michigan or have a limited known distribution. Data from CABI ISC (2016) and GISD (2016). The Global North and some newly industrialized countries (e.g. S1, results included 886 terrestrial plants, 222 arthropods, 72 mammals, 66 fish, 52 aquatic plants, 37 birds, 21 reptiles, 14 amphibians and 147 other organisms. This rapid reproduction contributes to the speed with which they can spread. SNat ≥ 56); 16% have SNat ≥ 126. Salinity tolerance and geographical origin predict global alien amphipod invasions. Spatial Surveillance of Invasion by Alien Species in a Heterogeneous Ecological Landscape. China is the native country of 257 species recorded as IAS in other countries (SNat). Growing up to one foot per day, kudzu covers everything in its path—from grasses to mature trees. The roots often grow so densely that they smother nearby native vegetation. The five countries that contribute the most IAS to other countries are China (SNat =257), India (SNat = 230), Mexico (SNat = 218), Turkey (SNat = 193) and France (SNat = 186) with the Asia Pacific region being the biggest ‘exporter’ of IAS, with 603 species native to that region being invasive elsewhere. Today, we recognize that invasive plants also harm lakes, streams, wetlands, and ecosystems. Top offenders include the Asian longhorned beetle, Asian citrus psyllid, brown marmorated stink bug, European gypsy moth and emerald ash borer. Data from CABI ISC (2016) and GISD (2016). Economic use of plants is key to their naturalization success. Then check out our new State Updates. For more information on specific aquatic invasive species, visit the National Invasive Species Information Center’s partial listing of aquatic invasive species. Over 85 countries (excluding overseas territories) have SInv ≤ 15, with 42% of these countries being located in Africa and West Asia; 19 countries have SInv ≥ 100. Most invasive plants have astounding reproductive capacity, producing large quantities of seed with high germination rates. Alien futures: What is on the horizon for biological invasions?. We are the nation's most respected bipartisan organization providing states support, ideas, connections and a strong voice on Capitol Hill. S2c) are introduced through ‘Aquaculture’ (AQ) and TRA, respectively, and 28 (39%) and 23 (32%) of 72 unique species of mammals (Fig. The bars are in descending order of number of species from top to bottom (see legend) with the category “other” includes the following organism types: alga, annelid, flatworm, fungus, micro‐organism, mollusc, nematode, oomycete, parasites and virus. Plant invasions in Italy: An integrative approach using the European LifeWatch infrastructure database. Both databases were created in response to the need for a global information system on invasive species and to enable the distributions of IAS to be mapped (Ricciardi et al., 2000; CABI ISC, 2016). Number of invasive alien species by introduction pathways from a geographical region using chord diagrams for intentional egress of: (a) plants, (b) arthropods, (c) fish, (d) mammals, (e) birds, and (f) reptiles. States are taking aim at fighting aquatic invasive species. Recreational angling as a vector of freshwater invasions in Central Italy: perceptions and prevalence of illegal fish restocking. According to the U.S. Forest Service, invasive species have contributed to the decline of 42 percent of threatened and endangered species. Global map of SNat, the number of species native to a country but considered invasive alien species (IAS) in other countries, as based on the Global Invasive Species Database (GISD, 2016) and the CABI Invasive Species Compendium (CABI ISC, 2016). Number of invasive alien species by introduction pathways to a geographical region using chord diagrams for unintentional ingress of: (a) plants, (b) arthropods, (c) fish, (d) mammals, (e) birds, and (f) reptiles. Bruce D. Malamud is a physical scientist specializing in visualization of data, time‐series analysis, and the confrontation of models with data in the broader environmental sciences. With the looming threat of invasive mussels, many states have implemented watercraft inspection and decontamination (WID) programs. This paper's scope is global and therefore includes signatory and non‐signatory countries of the Convention on Biological Diversity (CBD, 2010). This was to avoid duplication of data and focus the research on IAS as defined in the Introduction. What can individuals do to curb the spread of invasive species? To combat invasive plants, Washington has a system of county weed boards and local weed districts, and laws that require landowners to control inv… As shown in Fig. Invasive beetles, moths and other insects are destroying millions of trees across the country. Figure S1 Breakdown of recorded invasive alien species by organism type. Carp have systematically progressed north and can now be found in the Illinois River. Many countries have a number of species native to that country that have become invasive elsewhere; we represent these using the variable SNat and plot them globally in Fig. Global databases such as the GISD, CABI ISC or ECOLEX, which record legal instruments globally, have been created to deal with these issues and represent important sources of information that can be effectively utilized to aid pattern visualization and guide the control and management of IAS. To aid visualization of smaller land areas, circles represent countries with Use of multispectral satellite datasets to improve ecological understanding of the distribution of Invasive Alien Plants in a water‐limited catchment, South Africa. Robert A. Francis is a geographer and ecologist with interests in human–environment interactions, particularly in relation to urban and freshwater ecosystems and invasive alien species. As native plant species are displaced by invaders at alarming rates, habitat for wildlife is also damaged. Out of 342 national/sub‐national relevant documents put in place since 1980, 154 pieces of legislation/regulations across 70 countries have a relevance score of 3 or 4, which shows that a genuine effort is being made to manage invasive species (see Table S4). With its overseas territories, France is signatory to regional treaties such as the Convention on Conservation of Nature in the South Pacific (1976) and the Plant Protection Agreement for the Asia and Pacific Region (1956). iMapInvasives is an online, collaborative, GIS-based mapping tool and the official invasive species database for NY. S2–S5 on p.3 for more detailed information on the chord diagrams and for introduction pathway abbreviations. Knowledge & Management of Aquatic Ecosystems. Further data analysis shows that the percentage of the total invasive terrestrial plants recorded as introduced for each region through HORT is >50% for Africa, Asia Pacific, Europe, North America and West Asia and 39% in Latin America and the Caribbean. under climate change scenarios. Understanding the spread and impact of exotic geckos in the greater Caribbean region. Global map of the number of invasive alien species (IAS) per country, excluding overseas territories, based on the Global Invasive Species Database (GISD, 2016) and the CABI Invasive Species Compendium (CABI ISC, 2016). Further data analysis indicates that between the seven global regions, after removing duplicate species, HORT has 465 unique IAS (31% of the 1517 species in our databases) introduced globally. According to the seminal paper by David Pimentel, Lori Lach, Rodolfo Zuniga, and Doug Morrison, the economic damages associated with invasive species in the U.S. exceeds $120 billion per year. See Figs S2–S5 for chord diagrams broken down by organism type and the number of IAS that ingress and egress to a geographical region intentionally and unintentionally. Invasive.org is a joint project of University of Georgia - Center for Invasive Species and Ecosystem Health, USDA Animal and Plant Health Inspection Service, USDA Forest Service, USDA Identification Technology Program, and USDA National Institute of Food and Agriculture S2d) are introduced via IR and TRA, respectively. This is partly due to bias in species records (Pyšek et al., 2008), difficulties in generating adequate data (because data quality varies) (EEA, 2012) and high uncertainty in the information on species pathways (Hulme, 2015). Number of invasive alien species by introduction pathways from a geographical region using chord diagrams for unintentional egress of: (a) plants, (b) arthropods, (c) fish, (d) mammals, (e) birds, and (f) reptiles. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. The circles in Fig. The dominant pathway for species invasions was horticulture and the nursery trade, with 31% of the species introduced outside of their natural geographical range. Whether they arrived accidentally on cargo ships or were intentionally sold as pets, invasive animals cause serious harm to natural ecosystems and cost states and the federal government billions of dollars each year. They reduce biodiversity, alter and degrade the environment, affect the productivity of agricultural ecosystems, and limit the ability of producers to access export markets - all of which hinders sustainable economic growth and development. Country data are matched using ISO3 codes (ISO, 2016). We have also supported the establishment of a network of local action groups to facilitate strategic action at a local scale. 2. Want a quick wrap-up of invasive species issues across Australia? Functional traits indicate faster resource acquisition for alien herbs than native shrubs in an urban Mediterranean shrubland. Advancements in satellite remote sensing for mapping and monitoring of Alien Invasive Plant species (AIPs). Figure S6 also gives the number of countries per year that have signed one or more IAS‐related international treaties in a given year for 1933–2015; 244 countries have signed one or more of the 48 treaties. Arthropods and marine organisms are the dominant organisms for unintentional introduction across all organism types with 91% of arthropods and 88% of marine organisms introduced unintentionally compared with 34% of plants and 28% of fish. Intentional introduction pathways of alien birds and mammals in Latin America. The brown tree snake, Burmese python, giant African snail, nutria and wild boar are just a few of the species receiving national attention. ) and For instance, West Asia ‘exports’ a higher number than it ‘imports’ as opposed to Europe, which ‘imports’ more than it ‘exports’. Indeed, these three countries are former colonies and have major international shipping ports (World Bank, 2014). All instruments returned from the search were assigned an integer ‘relevance score’ from 0 to 4 to differentiate legal instruments based on their degree of focus on IAS: First, an IAS asymmetry index Κ (kappa) was developed to highlight the imbalance of ingress/egress of IAS for a given country: orcid.org/http://orcid.org/0000-0003-1572-5357, I have read and accept the Wiley Online Library Terms and Conditions of Use, Global biodiversity: indicators of recent declines, CABI ISC (Centre for Agriculture and Biosciences International Invasive Species Compendium), History of biological invasions with special emphasis on the Old World, Biological invasions: a global perspective, Mammal invaders on islands: impact, control and control impact, DAISIE (Delivering Alien Invasive Species Inventories for Europe), Phytogeography of the north‐eastern coast of the Caspian Sea: native flora and recent colonisations, EDDMapS (Early Detection and Distribution Mapping System), The ecology of invasions by animals and plants, Crossing frontiers in tackling pathways of biological invasions.
