Firewood Movement Regulation, Outreach, and Impact

Leigh Greenwood, Forest Pest and Pathogen Program Director, TNC

Thursday, October 10th, 2024 10:00 AM
Firewood movement regulations, recommendations, outreach, and forest pests’ distribution change through time. The Don’t Move Firewood campaign is a leader in this space, not only for excellence in communicating behavior change messages to the public, but also as a professional resource to track and communicate regulatory frameworks and pest range shift information. This presentation will cover the basics of current firewood regulations in the USA, what resources Don’t Move Firewood has for both the layperson and for forest and firewood professionals, and- when it all comes together- how we can slow the spread of damaging forest pests and pathogens across the country.

Emerging Sassafras Wilt in Indiana

Olivia Bigham, PhD Student, Ginzel Lab

Thursday, October 17th, 2024 11:00 AM
Since 2019, sassafras trees in the Central Hardwood Forest Region have been wilting, yet the cause remains unknown. Initially, it was suspected that laurel wilt, a deadly disease of sassafras and other laurel species, had spread. However, neither its primary insect vector (Xyleborus glabratus) nor the causal agent of laurel wilt (Harringtonia lauricola) have been detected. However, investigations of material from wilting trees revealed two non-native ambrosia beetles (Xylosandrus germanus and X. crassiusculus) and a potentially novel fungus closely related to Ophiostoma quercus.

Lenny Farlee, Purdue Extension Forester

Wednesday, November 13th, 2024 10:00 AM
Identification features will be outlined to help you identify invasive trees that may be similar to some of our native forest trees here in the Midwest. Field identification is important to select species to control and species to retain in invasive plant management. Field ID characteristics will be provided to help you separate the native from the exotic invasive.

Biological invasion by emerald ash borer threatens keystone species indelibly entwined with Indigenous cultures

Nate Siegert, US Forest Service, State, Private & Tribal Forestry, Forest Health Protection

Thursday, December 12th, 2024 10:00 AM
Black ash (Fraxinus nigra) has cultural and spiritual significance to many Tribal Nations in the US and First Nations in Canada, but unfortunately is also the most highly preferred and vulnerable host of emerald ash borer (EAB) in North America. Tune in to learn more about black ash, its importance to cultural lifeways of Indigenous people, and the ongoing efforts to mitigate the impacts of the EAB invasion on this cultural keystone species.

The Urban Wood Network's mission is to inform, collaborate, and connect to build business and consumer confidence in the urban wood industry. It strives to:
  • Build regional and national awareness of the urban wood market by bringing together urban wood efforts in Illinois, Michigan, Missouri and Wisconsin and beyond, providing leadership and sharing information.
  • Strengthen the urban wood supply chain within the four states with the goal of increasing the amount of urban wood that can be reclaimed, processed, and sold.
  • Build a common understanding, language, commitment, and eventually, brand for the urban wood marketplace.

The economics of area-wide ash surveillance, treatment, and removal strategies to slow the spread of emerald ash borer in urban forests

Robert G. Haight, USDA Forest Service, Northern Research Station, St. Paul, MN

04/01/21
The emerald ash borer (EAB) is one of the most economically and environmentally damaging invasive species ever to reach the United States. Economic damage of EAB is most severe in cities that lose abundant high-value ash trees growing along streets and in yards. Pest management and economic models suggest that an area-wide approach across all ownerships, including surveillance for early detection, treatment of ash trees with systemic insecticides, and removal of infested ash trees, yields the greatest benefits at the lowest costs. In this talk, Bob Haight will present research on the economics of area-wide strategies in Minneapolis/Saint Paul metropolitan region, the city of Winnipeg, Manitoba, and the state of New Jersey. The key findings for resource managers are:
  1. Surveillance for early detection of infested trees pays off. Waiting to apply surveillance and management risks the buildup of the EAB population causing more damage and economic loss.
  2. Once surveillance identifies infested trees, cost-effective actions include treating newly infested trees and removing highly infested trees. If the budget is limited, treating newly infested trees is the priority.
  3. For risk averse managers who want to minimize the risk of overwhelming ash mortality, the cost-effective strategy is to monitor and remove ash trees in the vicinity of infestations.
  4. Cooperation among city governments and private landowners can increase benefits for all.

Detecting and Monitoring Invasive and Non-Native Species from NEON Pitfall Traps

Michael D. Weiser, University of Oklahoma

04/22/21
NEON (the National Ecological Observatory Network) uses pitfall traps to collect ground beetles (Carabidae) at 47 sites across the continental USA, Hawaii, Alaska, and Puerto Rico. NEON technicians remove these beetles and retain all other pitfall organisms as “Invertebrate Bycatch.” Using a combination of next-generation metagenomic sequencing and high-resolution digital imaging we have developed processes to non-destructively sample and identify taxa from the ethanol storage media. We are able to use these data to detect and monitor range expansions in some non-native species.

Replanting After a Crisis: Worcester’s Recovery from Asian Longhorned Beetle

Ruth Seward, Worcester Tree Initiative

03/05/19
Asian longhorned beetle is a death sentence for any tree it infests. In order to successfully recover from it, cities and communities must be strategic about the trees they choose to replant and how they work together to bring back their urban forests. In Massachusetts, the Worcester Tree Initiative (WTI) was formed in 2009 in order to help replant the 30,000 trees that were initially cut in the Worcester area following an ALB infestation. WTI continually engages with residents in the ALB Zone by offering community planting opportunities as well as tree care education programs. Through partnerships with the City of Worcester Forestry Department, the Dept of Conservation and Recreation and the community at large, 30,000 trees were successfully replanted but the work of WTI remains relevant today as a community advocacy and engagement program of Tower Hill Botanic Garden. Learn how to use the lessons learned in this highly impactful program in your own response to invasive ins

This talk will share information on general earthworm biology and identification, impacts, control options, and the latest research findings.

What We Know So Far -- How Feeding & Mating Behavior are Related to Lycorma delicatula Flight Dispersal

Tom Baker, Dept. of Entomology, Center for Chemical Ecology, Penn State University, University Park, PA

10/29/22
This presentation involves the study of flight dispersal of Lycorma delicatula in PA -- are there predictable directional and distance components that could help predict new locations to which the infestations may spread? In 2017 and 2018, adults were observed launching themselves into the wind from all types of host and non-host trees, or from porches, posts and other human-made structures.

Lessons Learned from a Test of an Emerald Ash Borer Urban SLAM Program

Cliff Sadof, Dept. of Entomology, Purdue University

11/05/22
Urban SLAM, or Slowed Ash Mortality, is an approach to managing emerald ash borer with fewer pesticides. Although this approach has been tested rigorously in the rural forests, operational tests of this approach are lacking in urban forests. In this webinar I will review the result of a six-year study that shows how the starting condition of the forest, ash species composition, density of trees, and choice of pesticide can influence the outcome of this approach.

Dicamba/2,4-D & Trees: Old Herbicides Causing New Problems

Robbie Doerhoff, Forest Entomologist, Missouri Department of Conservation

11/12/22
Dicamba and 2,4-D have traditionally been used during the early part of the growing season, when trees and other sensitive plants are still dormant. With the release of soybean varieties tolerant of these herbicides, summer applications are resulting in tree and native plant injury on a landscape level. This webinar will discuss the history of this issue and illustrate herbicide injury on trees.

Responses of non-native species to climatic change and their implications for management

11/19/22
The establishment and subsequent abundance of non-native species, such as introduced pests and the natural enemies imported to combat them, is in part determined by the climatic suitability of the novel habitat. For non-native species that have been established for decades, shifting climatic regimes could cause deviations from historical patterns of abundance. I will discuss some potential mechanisms for how climate change might alter host-parasitoid dynamics, using the invasion of, and importation biological program against, larch casebearer in North America as a case study.

Long-term Impacts and Management of Emerald Ash Borer

Kathleen Knight, Research Ecologist, U.S. Forest Service

02/03/22
The emerald ash borer, an invasive insect, has spread from its initial introduction in Michigan and killed millions of ash trees across the region. All six ash species native to its introduced range are susceptible to this pest, and the effects of EAB differ in the different kinds of ecosystems inhabited by these different ash species. Our long-term monitoring program has provided insights into the impacts of EAB on forests and on the long-term dynamics of ash species. Looking to the future, integrated pest management strategies can be used in situation-specific combinations to reduce and mitigate effects of EAB.

The biology and management of the invasive spotted lanternfly, Lycorma delicatula

Holly Shugart, PhD. Postdoctoral Scholar, Pennsylvania State University

02/24/22
The biology of the invasive spotted lanternfly poses a uniquely challenging threat to many agricultural crops, ornamentals, and, to a lesser extent, forests. Spotted lanternflies are highly polyphagous, can inhabit a wide climatic range, and thus have the potential to become established in many regions of the United States. Additionally, SLF females often lay their eggs on personal vehicles, commercial trucks, train cars, and many other items, all of which increase the probability that SLF may be accidentally moved into new habitat ranges. Successful management incorporate an integrative approach including: a community education & reporting system, selected insecticide applications by state and federal agencies, and education, training, and permitting of commercial and business operations moving in and out of quarantine zones. The complex biology of this adaptable insect pest requires a multi-disciplinary approach and there is much still to learn about SLF biology.

Firewood Rules, Certifications, and Recommendations across the USA

Leigh Greenwood, Forest Health Program Director, North America Region, The Nature Conservancy

03/01/22
The federal deregulation of emerald ash borer in January 2021 was widely expected to lead to many changes in the regulatory environment around firewood in the USA. This webinar will highlight the release of a new report written by staff of The Nature Conservancy’s Don’t Move Firewood campaign, covering what regulations and recommendations are in place a year after the EAB deregulation was finalized. We will describe how the current regulatory environments applying to the inter- and intra-state movement of firewood vary greatly in type and prevalence across the United States. The dynamic situation of many forest pests, coupled with the different challenges faced by the state agencies’ statutory authorities and priorities, forest conditions, and unique geographies, have all combined to create a complex regulatory mosaic- and as a result, a very challenging outreach environment.

The worst kind of snowbird: the invasive of Asian longhorned beetle in South Carolina

David Coyle, Assistant Professor and State Extension Specialist, Clemson University

03/03/22
The Asian longhorned beetle, Anoplophora glabripennis (ALB), was found in South Carolina in May 2020, which now represents the southernmost infestation in North America. Eradication efforts are underway, but several challenges persist due to the novel climate and environment in which ALB has established. This talk will provide a refresher on ALB biology and identification, as well as established and potential eradication methods being used in South Carolina. We will discuss how ALB likely arrived in the Deep South, and also why the threat of more ALB movement and new infestations is unlikely to cease.

Changing the common name of the non-native forest pest Lymantria dispar (Formerly “gypsy moth”)

Jonathan Walter, University of Virginia

03/09/22
In July 2021, the Entomological Society of America decertified “gypsy moth” as the official common name of the non-native forest pest Lymantria dispar in the United States. This decision set in motion a process to rename the species. While renaming species is not uncommon, this case is particularly noteworthy and complex due to L. dispar’s status as a high-profile pest with major research, regulatory, management, and public outreach activities. A decision is expected shortly on the proposed new common name, “spongy moth,” which derives from common names used in its native range and francophone Canada and refers to the sponge-like characteristics of L. dispar egg masses. This talk will address why a new common name was needed, the process for selecting a new name, and next steps for implementing the name change.

Tree of Heaven: Management and Identification

Lenny Farlee, Extension Forester, Purdue University

03/31/22
Tree-of-Heaven, Ailanthus altissima, is an aggressive invasive plant causing in harm in urban and rural environments. Tree-of-Heaven is also a preferred host to an expanding invasive insect, Spotted Lanternfly, Lycorma delicatula. The dual threat posed by Tree-of-Heaven is motivating landowners and managers to control this invasive tree, but some techniques could make an infestation worse than it already is. We will outline several approaches to the control and management of Tree-of-Heaven to help you plan a successful strategy.

Forest Pest Damage from the Carbon Sequestration Perspective

Leigh Greenwood, Forest Health Program Director, North America Region, The Nature Conservancy

05/05/22
Both native and non-native forest insects and diseases across the contiguous United States are reducing the ability of the nation’s forests to capture and store carbon dioxide. This webinar will describe a study published in Fall 2021 in Frontiers in Forests and Global Change that calculated forests damaged by insects sequestered 69% less carbon than undamaged forests, while those affected by disease sequestered 28% less carbon. The webinar will briefly cover the overarching findings of the study, and then go into depth on what it means from the invasive forest pest perspective- including how to bring this issue to light when discussing prevention and management of forest pests, and what improvements to current actions could further mitigate these sequestration losses.

Breeding for EAB-Resistance: What Does the Future Look like for Ash?

Jennifer Koch, Research Biologist, US Forest Service

05/26/22
EAB threatens the survival of ash trees in the U.S. where it is a common hardwood species especially in riparian and wetland forests. Ash was also used extensively for soil conservation (including wind breaks) and in urban green spaces and streets. Surviving, or “lingering”, ash trees that had maintained healthy canopies for at least two years after all other large ash trees had died were identified in natural forests long-infested by EAB. EAB egg bioassay experiments confirmed that these trees have an increased level of resistance due to defense responses, including death of early instar larvae, larvae with significantly lower weights, or leaves less preferred for feeding by EAB adults. This webinar discusses research now being done to further understand this phenomenon and other findings to develop tree-improvement programs that could be successful in producing EAB resistant seed. Longer term goals include combining the best performing progeny from many families into a second generation seed orchard, so that the seed produced may be used for restoration plantings.
