The United States has thousands of invasive species, representing a sizable, but unknown burden to the national economy. Given potential economic repercussions quantifying these costs is paramount importance both for economies and invasion management. Here, we used novel global database (InvaCost) quantify overall species in across spatiotemporal, taxonomic, socioeconomic scales. From 1960 2020, reported totaled $4.52 trillion (USD 2017). Considering only observed, highly reliable costs, this total cost reached $1.22 with an average annual $19.94 billion/year. These increased from $2.00 billion annually between 1969 $21.08 2010 2020. Most (73%) were related resource damages losses ($896.22 billion), as opposed management expenditures ($46.54 billion). Moreover, majority invaders terrestrial habitats ($643.51 billion, 53%) agriculture was most impacted sector ($509.55 taxonomic perspective, mammals ($234.71 billion) insects ($126.42 groups responsible greatest costs. apparent rising invasions, coupled increasing numbers current lack information known invaders, our findings provide critical policymakers managers.

Managing biological invasions: the cost of inaction

Biological Invasions, Год журнала: 2022, Номер 24(7), С. 1927 - 1946

Опубликована: Март 18, 2022

Abstract Ecological and socioeconomic impacts from biological invasions are rapidly escalating worldwide. While effective management underpins impact mitigation, such actions often delayed, insufficient or entirely absent. Presently, delays emanate a lack of monetary rationale to invest at early invasion stages, which precludes prevention eradication. Here, we provide by developing conceptual model quantify the cost inaction, i.e., additional expenditure due delayed management, under varying time efficiencies. Further, apply damage data relatively data-rich genus ( Aedes mosquitoes). Our demonstrates that rapid interventions following drastically minimise costs. We also identify key points in differentiate among scenarios timely, severely intervention. Any action during phase results substantial losses $$( > 50\%$$ (>50% potential maximum loss). For spp., estimate existing delay 55 years led an total approximately $ 4.57 billion (14% cost), compared scenario with only seven prior (< 1% cost). Moreover, absence action, long-term would have accumulated US$ 32.31 billion, more than times observed inaction cost. These highlight need for timely invasive alien species—either pre-invasion, as soon possible after detection—by demonstrating how investments reduce economic impacts.

The economic benefits of invasive species management

People and Nature, Год журнала: 2019, Номер 1(2), С. 124 - 137

Опубликована: Июнь 1, 2019

Abstract Invasive species are known to cause significant negative impacts ecosystems and people. In this paper, we outline the nature of these economic impacts, then present a range approaches for estimating costs invasive (including on biodiversity), thus benefits management programmes. The importance thinking clearly about most appropriate context valuation is stressed. We provide examples application non‐market management, show how such methods can be used measure public preferences over control undertaken. discuss some important problems in applying context.

Endophytes vs tree pathogens and pests: can they be used as biological control agents to improve tree health?

European Journal of Plant Pathology, Год журнала: 2019, Номер 155(3), С. 711 - 729

Like all other plants, trees are vulnerable to attack by a multitude of pests and pathogens. Current control measures for many these diseases limited relatively ineffective. Several methods, including the use conventional synthetic agro-chemicals, employed reduce impact diseases. However, because mounting concerns about adverse effects on environment variety economic reasons, this management tree chemical methods is losing ground.

The relationship between invader abundance and impact

Ecosphere, Год журнала: 2018, Номер 9(9)

Abstract The impacts of invasive species generally increase with their abundance, but the form invader abundance–impact relationships remain poorly described. We highlight utility curves for three questions. First, can clarify whether prevention and management should focus on likely to become abundant or those cause large per individual. Second, comparing between native exotic reveal any systematic differences in effects ecological systems. Third, identifying thresholds relationship impact abundance be used select targets design control strategies. With increasing extent resolution datasets organisms worldwide, we now have opportunity explore detail context dependence relationship. Doing so provides opportunities improve prediction impact, better understand resident organisms, scale from localities ranges.

Economic costs of biological invasions within North America

Invasive species can have severe impacts on ecosystems, economies, and human health. Though the economic of invasions provide important foundations for management policy, up-to-date syntheses these are lacking. To produce most comprehensive estimate invasive costs within North America (including Greater Antilles) to date, we synthesized impact data from recently published InvaCost database. Here, report that cost American economy at least US$ 1.26 trillion between 1960 2017. Economic climbed over recent decades, averaging 2 billion per year in early 1960s 26 2010s. Of countries America, United States (US) had highest recorded costs, even after controlling research effort each country ($5.81 source US). taxa habitats could be classified our database, vertebrates were associated with greatest terrestrial incurring monetary impacts. In particular, cumulatively (from 1960–2017) agriculture forestry sectors 527.07 34.93 billion, respectively. Reporting issues (e.g., quality or taxonomic granularity) prevented us synthesizing all available studies. Furthermore, very few known reported costs. Therefore, while massive, is likely conservative. Accordingly, expanded more rigorous reports necessary invasion estimates, then support data-based decisions actions towards invasions.

Forest Insect Biosecurity: Processes, Patterns, Predictions, Pitfalls

Опубликована: Окт. 6, 2022

The economic and environmental threats posed by non-native forest insects are ever increasing with the continuing globalization of trade travel; thus, need for mitigation through effective biosecurity is greater than ever. However, despite decades research implementation preborder, border, postborder preventative measures, insect invasions continue to occur, no evidence saturation, even predicted accelerate. In this article, we review measures used mitigate arrival, establishment, spread, impacts possible impediments successful these measures. Biosecurity successes likely under-recognized because they difficult detect quantify, whereas failures more evident in continued establishment additional species. There limitations existing systems at global country scales (for example, inspecting all imports impossible, phytosanitary perfect, knownunknowns cannot be regulated against, noncompliance an ongoing problem). should a shared responsibility across countries, governments, stakeholders, individuals.

Invasive alien species (IAS) are a major driver of global biodiversity loss, hampering conservation efforts and disrupting ecosystem functions services. While accumulating evidence documented ecological impacts IAS across geographic regions, habitat types taxonomic groups, appraisals for economic costs remained relatively sparse. This has hindered effective cost-benefit analyses that inform expenditure on management interventions to prevent, control, eradicate IAS. Terrestrial invertebrates particularly pervasive damaging group invaders, with many compromising primary sectors such as forestry, agriculture health. The present study provides synthesised quantifications caused by invasive terrestrial the scale range descriptors, using InvaCost database. cost economy US$ 712.44 billion over investigated period (up 2020), considering only high-reliability source reports. Overall, were not equally distributed geographically, North America (73%) reporting greatest costs, far lower reported in Europe (7%), Oceania (6%), Africa (5%), Asia (3%), South (< 1%). These mostly due insects (88%) resulted from direct resource damages losses (75%), forestry; little (8%) was invested management. A minority monetary directly observed (17%).
