XXVI IUFRO World Congress 2024 – session "Never waste pandemics: lessons learned from past forest disease outbreaks"

by Ari Hietala

Dear colleagues, In case you are planning to participate in the XXVI IUFRO World Congress in Stockholm, Sweden in 23-29 June 2024, please consider whether you would like to contribute to the session “Never waste pandemics: lessons learned from past forest disease outbreaks”. The session includes 15-minute talks and posters; submissions are now open: https://iufro2024.com/call-for-congress-abstract. Abstracts will be accepted until 2 June 2023. Never waste pandemics: lessons learned from past forest disease outbreaks Disturbances, whether abiotic or biotic in nature, are integral and necessary components of forest ecosystems. However, anthropogenic pressures and climate changes have contributed to the erosion of forest ecosystem resilience, frequently to a degree that the tipping point has been breached, this causing devastating consequences across landscapes, countries and even continents. With globalization and changes in climate patterns, both natural and planted forests are at risk from invasive exotic pathogens, which are exacerbated by extended drought cycles, extreme precipitation events and air pollution. As an example, owing to the scale of pandemic destruction, Ash dieback, Dutch Elm Disease, Chestnut Blight, along with White Pine Blister Rust, are, so far, among the most catastrophic biotic disturbances in forest. The list of devastating disturbances is long and novel drivers will keep arising in the globalized world due to ongoing climate warming. Experience so far tells that it is less costly to conserve nature than it is to restore it, so it is imperative we learn from experience to protect forests now. Our future relies on maintaining the ecosystem services provided by forest. The ongoing transition from a fossil fuel-based economy to a biobased economy is driven by the need to combat climate change, to protect the environment and to increase sustainability. This means we aim to meet the needs of the present generation without compromising the ability of future generations to meet their needs. When governmental roadmaps towards more carbon-neutral economies are drafted, the focus, concerning forests, is often only on the increase of forested area and management practices that facilitate forest growth. The underlying assumption is that forests are healthy and in different phases of growth, a demography that allows the balancing needed between carbon sequestration and a continuous flow of the biogenic material needed. However, pest and pathogen outbreaks, as history has shown, can severely disrupt our ambitions. In this session, we welcome presentations that address how the underlying ecological, societal and institutional drivers have contributed to the rise and scale of specific disturbances. We hope to highlight assessments of currently implemented strategies considering the lessons learned from past pandemic crises. Similarly, we hope to outline management and policy options that are not yet in force or which have not yet attained that are not yet in place or not yet as but that would be needed to successfully prevent and/or to circumvent future pandemic crises.

Session IUFRO 2024: ‘Risk-based surveillance for quarantine forest pests’

by Benno Andreas Augustinus

Dear managers of the forent and forpath mailing lists, Would it be possible to send the following mail through the mailing list to promote a session in next year’s IUFRO meeting in Stockholm (and to remind people that the deadline for abstract submissions is coming up)? Dear colleages, The deadline for abstract submissions for the IUFRO 2024 meeting in Stockholm is coming up, and we would like to use the opportunity to motivate you to send abstracts for the session ‘Risk-based surveillance for quarantine forest pests’. Description of session: Ongoing globalisation results in increased introductions of non-native organisms in novel environments, mainly connected to trade activities. Some of these organisms can become forest pests, with devastating results. Globally, countries have implemented different schemes of national surveillance for invasive pests and pathogens. National Plant Protection Organisations (NPPOs) are responsible for the surveillance of pests in their countries, as well as their control (eradication, containment). Preventing the introduction and spread of plants pests, is more cost effective than controlling and mitigating the impact of pests once they have established in a territory. To add to the unknowns, many invasive forest pests become only known to science after introduction in a novel environment. Identifying these threats beforehand (for example by using ex-patria sentinel plantings) is necessary to inform further steps. Furthermore, the pathways of introductions need to be investigated, for example by comparing global trade and invasion patterns, identifying hotspots for invasions and areas particularly suitable for the establishment and spread of invasive pests. Early warning systems (like trapping programs or in-patria sentinel plantings) can then be deployed to inform reactive management like quarantine and eradication efforts. It is of high importance that the benefits of the surveillance and management of quarantine forest pests outweigh the risks of an outbreak, which can be assessed using bio-economic models. Different surveillance schemes are being developed for and by different countries. Especially on the international level, communication in between countries is limited, while the challenges and opportunities are similar internationally. This session’s ambition is to inform and connect national surveillance schemes on an international level, and scientists that are working on the interface of research and implementation. It also aims to inform decision makers and risk assessors on: 1. Identification of future biotic threats before arrival 2. Identification of pathways 3. Implications for (inter)national measures for surveillance Kind regards, the organizers of this session (Benno Augustinus, Maria Chiara Rosace, Andrea Battisti, Brett Hurley, Etsuko Kagaya, Victoria Lantschner, Vittorio Rossi, Valentin Queloz, and Eckehard Brockerhoff)

Soliciting submissions for session T2.6 IUFRO World Congress 2024

by Brigitte Burger

Dear all, We are co-organizing a technical session in the Theme 1 (T1.35) at the IUFRO Congress in Stockholm, 2024 about the use of RNA strategies (including hypovirulence and RNAi) for the management of forest pest and diseases. Technical Theme 1. Strengthening forest resilience and adaptation to stress T1.35. Use of RNA strategies for the control of forest pests and diseases: mycoviruses and interfering RNA The search for environmentally-friendly products for plant disease management is a priority worldwide. RNA interference (RNAi)-related tools and strategies as well as (myco)virus-mediated biocontrol may offer a promising solution. RNAi is a gene regulatory system, conserved in eukaryotic organisms, that silences the expression of certain transcripts in a sequence-specific manner via double-stranded RNA (dsRNA) processing. Transgenic expression or topical application of dsRNAs induces systemic gene silencing against forest pathogens in target organisms. Mycoviruses or fungal viruses are widespread in all major taxa of fungi, and have increasingly been isolated and characterized in recent years. While they are largely symptomless, some confer hypovirulence to their host phytopathogenic fungi with potential as biological agents. This session will deal with those two environmental-friendly methodologies for forest disease management. The session includes talks and posters and the deadline for submission is 2 June 2023. In the following link you will find information about the congress https://iufro2024.com/call-for-congress-abstract<https://urldefense.com/v3/__https:/iufro2024.com/call-for-congress-abstract…>.

IUFRO Congress session on history of forest health management

by Andrew Liebhold

Dear Forest Pathoids: We would like to invite you to submit abstracts to our technical session for the IUFRO Congress in Stockholm, 2024. We would be especially delighted to receive contributions that include different disciplinary and practical perspectives to address forest health issues. *“Learning from the past to better inform the future: integrated approaches to increase forest health and resilience”* Trees, woods and forests provide significant socio-cultural, ecological and economic benefits. Science has highlighted the exponential increase in the introduction and spread of invasive species due to the growth in trade and travel, the speed and volume at which they travel and the difficulties of protecting porous boundaries. Climatic changes have supported establishment of introduced pests and pathogens or explosions of native species pushing large swathes of forests to their limits of resilience. Human attitudes and actions play an important role in the future resilience of forests but tree managers face a difficult task in identifying the right approach to take when faced with ecological, social and political uncertainty. History has much to teach us. A holistic and interdisciplinary approach to promoting forest health requires multiple disciplines and perspectives and acknowledgement that different societies will favour specific approaches, but we can learn from each other. This session will focus on the historical evolution of different forest health management activities influenced by political and/or economic transitions, cultural transformations and societal trends. We seek to share stories of pest and pathogen management where the outcomes were considered successful or not so successful, why and what next. Top-down management regimes are no longer considered acceptable despite their continued existence in some parts of the world. Instead, we recognise a shift towards an ethical and just approach wider engagement is necessary to ensure that management approaches for forest health are resilient and acceptable. Our speakers will share their stories of lessons learned and we will end with an interactive panel session encouraging audience participation on approaches to co-designing a biosecure and resilient future. The session includes 15-minute talks and posters; submissions are now open: https://iufro2024.com/call-for-congress-abstract. *Abstracts will be accepted until 2 June 2023.* We look forward to receiving your submissions to this session. Kind regards, *Mariella Marzano, Sandy Liebhold , Maartje Klapwijk , session organisers.* Andrew Liebhold https://www.fs.usda.gov/research/about/people/aliebhold Northern Research Station 304-285-1512 USDA Forest Service 304-285-1505 FAX 180 Canfield St. 724-317-8668 mobile Morgantown, WV 26505 USA

IUFRO Stockholm - technical session on Needle diseases of conifers

by Caterina Villari

Dear all, We would like to invite you to submit an abstract for an oral/poster contribution to our technical session on needle diseases of conifers at the 2024 IUFRO Congress in Stockholm<https://www.iufro.org/events/congresses/2024/>. Session title: Needle diseases of conifers: a globally rising threat to natural and planted forests Session number: T1.20 Session Description: The damage caused by foliar pathogens in coniferous forests is on the rise globally, causing severe concerns for the management of both planted and natural forests. While some pathogens are host specific, such as the causal agent of Swiss needle cast on Douglas fir, others, such as those in Dothistroma or Lecanosticta, colonize a variety of hosts. Regardless, they are causing sporadic outbreaks across the globe, likely due to climate change or the mostly accidental introduction of new strains into areas. Despite the numerous species that can be classified as needle diseases (e.g., those in the genera Coleosporuim, Dothistroma, Lecanosticta, Lophodermella, Lophodermium, Passalora, Phaeocryptopus, and Rhizosphaera, just to name a few), they have many traits in common, even across those colonizing different host species, and current research on needle diseases can benefit from exchanging experiences from different systems. This session will cover and welcome a broad range of topics related to both pathogens and endophytes of needles, including their origin and dispersal, their geographic distribution, management options, the differential susceptibility of their hosts, and their resistance mechanisms. We will also cover current advances in pathogen genomics and population genetics, as well as diagnostics. Session Organizers: Irene Barnes (FABI, South Africa), Michelle Cleary (SLU, Sweden), and Caterina Villari (UGA, USA). The session includes talks and posters and the deadline for submission is 2 June 2023: https://iufro2024.com/call-for-congress-abstract. We hope you will consider contributing to this session!
