Pensoft joins the FORSAID project in the next chapter for forest health

With its extensive experience in science communication and dissemination, Pensoft will help maximise FORSAID’s impact and ensure its long-term legacy.

As the dedicated communication partner of the project, Pensoft will lead efforts to popularise a new early detection paradigm targeting forest pests in Europe

The issue of pest proliferation is felt more acutely than ever in the wake of globalisation and climate change. As pests and pathogens spread across biomes, the threat to forests and the health of the plants within is only increasing. Cognisant of this worrying trend, the European Union has actively pursued mitigation and prevention measures over the last few years. Grassroots efforts are also on the rise as insights from academia and citizen science alike improve monitoring capabilities on the ground.

To address the core of the problem in its entirety, greater coordination and innovation across the board are required.

It is with this tenet in mind that FORSAID: FORest Surveillance with Artificial Intelligence and Digital Technologies – first emerged on the scene as a Horizon Europе-funded project. 

The goal of FORSAID is the inception and deployment of a technology-based early detection system for EU-regulated forest pests. 

The pursuit of that very goal brought together 17 partner organisations from 10 countries. FORSAID is funded by the European Union’s Horizon Europe research and innovation programme. Having officially started in September 2024, it is set to continue until February 2028.

Within the team, Pensoft has taken the lead in the domains of Communication, Dissemination and Exploitation. Its long-standing expertise vis-a-vis public campaigns for science initiatives will be harnessed in an attempt to show the benefits and solutions that the latest digital innovations can bring to plant health monitoring. Thus, Pensoft is to help maximise FORSAID’s impact and ensure its long-term legacy. 

The project will be presented across the public domain by following a tailored communication plan. Examples of its implementation include social media campaigns, regular updates of a dedicated FORSAID website and synergies with various stakeholder groups.

Foresight in FORSAID

The project consortium firmly believes that digital innovation is the key to a truly effective pest detection framework. This signifies the central role of technology at all stages of this paradigm’s development process. 

More specifically, the employment of digital tools will proceed on several levels: 

  • Satellite and drone surveillance will be employed to remotely map out forested areas of interest and assess the extent of plant damage caused by pests and pathogens.
  • Smart traps and DNA barcoding will serve to identify and sort out different species of pests.
  • Artificial intelligence (AI) models will assist throughout this process as it helps to automate the procedure, thereby increasing efficiency. 

Building on the technology-based research and experimentation, insights from a variety of stakeholders will also be gathered to crystalise FORSAID’s approach.

 The consortium’s intent here is the consolidation of a network of interested and involved actors who would ensure the long-term application of the project’s results. A special focus is also placed on citizen scientists, whose practical needs will be considered in the design of the digital tools developed within FORSAID. Finally, a detailed economic analysis will assess the early detection framework and its associated technological instruments, in order to ensure its usability in the long run.

New fungus found to cause cankers and declines in pistachio trees in Sicily, Italy

Starting in the spring of 2010, farmers from Sicily – the major pistachio production area of Italy – have been reporting a previously unknown disease on the trees. Characterised by cankers and declines, it sometimes leads to the collapse of the entire plant.

When the research team led by Salvatore Vitale, Centro di Ricerca Difesa e Certificazione, Italy, studied plants from a total of 15 pistachio orchards in Catania, Agrigento and Caltanissetta provinces, they identified cankers associated with vascular necrosis and tree decline on twigs, branches and stems, alongside abundant gummosis. There were also localised, sunken lesions with several central cracks. These lesions would deepen into the woody tissue, where discolouration and necrotic tissue were also present.

Additionally, the scientists conducted a series of pathogenicity tests on 5-year-old potted pistachio plants (Pistacia vera), which successfully reproduced the field observations. As a result, a previously unknown pathogenic fungus, which colonises the woody plant tissue, has been isolated.

Timelapse of the symptoms reproduced in a potted plant.

The aetiology of the disease and the description of the new species, named Liberomyces pistaciae, are published in the open access journal MycoKeys. Despite cankers and subsequent decline of pistachio trees having been observed in Sicily for several years, the paper is the first work to successfully determine the causal agent.

“On the basis of the high disease incidence and the frequency of this species observed in several orchards in the last years, we believe that L. pistaciae represents amenace to pistachio production in Sicily,” say the researchers.

Symptoms caused by the newly described pathogenic fungus observed in the field.

Out of the 15 surveyed orchards, the scientists detected the presence of the fungus in ten of them. Most of the observations occurred in the winter period and during late spring, but the authors found the pathogen in asymptomatic trees as well, which suggests that the fungus has a dormant growth phase.

When already symptomatic, the plants begin to exudate gum. Often, the bark on their trunks and/or branches would scale, appearing as if cracking and peeling. The initial pale circular areas present in the bark turn dark and sunken with time. Later, the infected patches were seen to expand in all directions, yet faster along the main axis of the stems, branches and twigs. When the scientists examined beneath the bark, they saw discoloured and necrotic tissues. Once the trunk of the tree is encircled by a canker, they report, the whole plant collapses.

Other symptoms include canopy decline as well as wilting and dying inflorescences and shoots growing from infected branches or twigs.

The newly described fungus is characterised with slowly growing colonies. With time, they turn from white to pale to dark brown with a whitish slightly lobed margin.

The researchers warn that essential hazard for the further spread and promotion of the infection is the use and distribution of infected propagation material taken from nurseries and mechanical injuries or pruning wounds.

Further research and studies are currently in progress aiming to extend the survey to other areas in order to eventually formulate effective disease management strategies.
