Crop protection and pest management are major economic and environmental concerns throughout Europe. The consultation of decision support systems (DSS) to guide decisions relating to Integrated Pest Management (IPM) is one of the key principles of IPM, reducing the ambiguity around potential risks to crop health. ‘Pests’ in this context include invertebrate pests, weeds and pathogens. The impact of DSS can be limited by a lack of awareness of DSS availability, inconsistencies in the user functions of different DSS, regional fragmentation of access, and a lack of transparency of the origin, validity, and benefits of DSS. Failure to address these limitations undermines trust in IPM DSS and leads to a reluctance of farmers and advisors to invest time in consulting multiple DSS sources as part of their agronomic decision toolbox. The EU-funded IPM Decisions project (Grant agreement ID: 817617) addressed these limitations by creating a Europe-wide free-access online platform. The IPM Decisions platform was designed in consultation with farmers, advisors and wider stakeholders to increase access to and uptake of IPM DSS integrated within it. It offers an end-point for IPM researchers and DSS developers to make adapted and novel DSS available to users, and provides a ‘one-stop shop' for farmers and advisors looking to consult free access or paid IPM DSS. Dedicated dashboards within the platform facilitate farm set up, consultation of DSS, comparison of DSS outputs, and adjustment of model parameters for adaption to different pests/regions. The IPM Decisions digital infrastructure enables easy integration of models and data with external platforms, providing a framework for accessing and sharing models and data between researchers and developers. The platform therefore provides both a ready to go user interface for new DSS, as well as the infrastructure to support and connect existing and future user interfaces.

In 2024, our sample remained stable with 27 participating countries and the largest number of assessed plots since 2019. We witnessed a very slight increase of 0.2 percentage points (%p) in mean defoliation as compared to 2023, mainly due to an increase of 0.5%p for broadleaves, while defoliation of conifers remained almost unchanged (0.1%p decrease). The strongest increase in defoliation occurred in deciduous (sub-) Mediterranean oaks (+2.1%p), while the strongest decrease was recorded in Norway spruce (-0.8%p). Deciduous temperate oaks had the highest (29.7%) and Norway spruce the lowest (22.4%) mean defoliation. Trend analyses show a considerable increase in defoliation of evergreen oaks (7.1%p), common beech (6%p), Norway spruce (5.5%p), and deciduous temperate oaks (5%p) over the past 20 years. The increase in defoliation for Scots pine and Mediterranean lowland pines (3.7 and 3.3%p, respectively) was more moderate. The results of the trend analyses were not significant for deciduous (sub-) Mediterranean oaks and Austrian pine. The percentage of trees with damage symptoms (48.6%) was almost the same as in 2023 (-0.5%p). As in previous years, the number of damage symptoms per assessed tree was substantially higher for broadleaves than for conifers (0.86 vs. 0.55, respectively). Insects, abiotic causes, and fungi were the most common damage agent groups for all species, comprising altogether more than half of all damage records. Tree mortality in 2024 was 1.1% (1 145 trees), i.e. at the same level as in the year before. While mortality rates for the main species and species groups ranged from 0.6 to 1.6%, mortality of Betula spp. and European ash was higher with 2.4% and 7% respectively.
