  author={Juliann E Aukema and Deborah G. McCullough and Betsy Von Holle and Andrew M. Liebhold and Kerry O. Britton and Susan J. Frankel},
Nonindigenous forest insects and pathogens affect a range of ecosystems, industries, and property owners in the United States. Evaluating temporal patterns in the accumulation of these nonindigenous forest pests can inform regulatory and policy decisions. We compiled a comprehensive species list to assess the accumulation rates of nonindigenous forest insects and pathogens established in the United States. More than 450 nonindigenous insects and at least 16 pathogens have colonized forest and…

Adopting stronger policies to reduce establishments of new forest insects and diseases would shift the major costs of control to the source and alleviate the economic burden now borne by homeowners and municipalities.

Biomass losses resulting from insect and disease invasions in US forests

The results indicate that forest pest invasions, driven primarily by globalization, represent a huge risk to US forests and have significant impacts on carbon dynamics.

Non-native Forest Insects and Pathogens in Australia: Establishment, Spread, and Impact

Geographic isolation, unique native flora, and a robust biosecurity system have resulted in Australia remaining free from many of the devastating exotic pests found in other countries. Nevertheless,

Ecology of forest insect invasions

An in-depth review of the traits of successful invasive forest insects and the ecological processes involved in insect invasions across the universal invasion phases (transport and arrival, establishment, spread and impacts).

Impact of Non-native Invertebrates and Pathogens on Market Forest Tree Resources

Several forest non-native pests and pathogens that are among the most frequently cited invasive species worldwide represent serious economic and conservation concerns for the forest ecosystems in

Ecological Consequences of Pathogen and Insect Invasions

    Current Forestry Reports
  • 2015
Variation in establishment success and ecological consequences exerted by nonnative forest insects and pathogens are discussed, characteristics of high-impact species are defined, and recent research on the ecological consequences of these high- impact species in forest ecosystems are reviewed.

Economic Impacts of Non-Native Forest Insects in the Continental United States

The damage estimates provide a crucial but previously missing component of cost-benefit analyses to evaluate policies and management options intended to reduce species introductions and could be similarly employed to estimate damages in other countries or natural resource sectors.

Increasing forest loss worldwide from invasive pests requires new trade regulations

It is shown that the number of forest pest invasions recorded for a given country has a significant positive relationship with trade (as indicated by gross domestic product) and is not associated with the amount of forested land within that country.

Firewood Transport as a Vector of Forest Pest Dispersal in North America: A Scoping Review.

This scoping review found limited research about western United States, Mexico, and Canada, various insect species and other organisms, regulation and management, awareness, and behavioral dimensions of firewood movement, as well as patterns in behavior related to forest pest dispersal throughFirewood movement in North America.



Nonindigenous species introductions: a threat to Canada's forests and forest economy1

Research needs include the development of enhanced detection capabilities, improved diagnostic tools, effective mitigation measures, as well as socio-economic impact assessments and basic biological information about nonindigenous species and their interactions with hosts.

Invasion of North American Forests by European Phytophagous Insects Legacy of the European crucible

Questions about managing these introduced insect species and concern about continued importation of new ones are timely because of the past severe and everspreading impacts of introduced insect pests on North American forest ecosystems.

Economic Impacts of Invasive Species in Forests

It is proposed that new methods for evaluating aggregate economic damages from forest‐invasive species need to be developed that quantify market and nonmarket impacts at microscales that are then extended using spatially explicit models to provide aggregate estimates of impacts.

Invasion by Exotic Forest Pests: A Threat to Forest Ecosystems

This work presents case histories that illustrate the invasion process via details of the arrival, spread, impact, and management of selected exotic forest pests.

Interceptions of Nonindigenous Plant Pests at US Ports of Entry and Border Crossings Over a 17-year Period

Insects dominated the PIN database, with the orders Homoptera, Lepidoptera and Diptera collectively accounting for over 75% of the insect records, while plant pathogens, weeds and mollusks accounted for 13, 7 and 1% of all pest records, respectively.

Airline Baggage as a Pathway for Alien Insect Species Invading the United States

Invasions by non-indigenous species are a problem of increasing magnitude and threaten the stability of the world's ecosystems and economies. Despite the enormity of this problem, relatively little

Diversity of non-native terrestrial arthropods on woody plants in Canada

The arrival rate of species in Canada increased from the late nineteenth century until about 1960, and declined rapidly thereafter, and seems to have reduced the rate of insect invasion.

Few immigrant phytophagous insects on woody plants in Europe: legacy of the European crucible?

It is proposed that fewer invasive phytophagous insects have become established in European compared to North American woodlands because of the unique legacy of the European Pleistocene/Holocene crucible.

Emerald ash borer: invasion of the urban forest and the threat to North America's ash resource.

The emerald ash borer (EAB), a phloem-feeding beetle native to Asia, was discovered killing ash trees in southeastern Michigan and Windsor, Ontario, in 2002. Like several other invasive forest pests,

Sudden oak death: endangering California and Oregon forest ecosystems

The high susceptibility of tanoak to infection and death suggests that P ramorum is an exotic pathogen, but its origins, and most details of its biology and ecology, remain unknown.
