Context
The decline in the abundance and diversity of European wild insect pollinators constitutes a dramatic issue for both biodiversity protection and food security due to the crucial role of pollination in the propagation of many plant species. To provide a framework for a coherent tackling of pollinators decline across the European Union, in 2018 the European Commission adopted the EU Pollinators Initiative (EUPI) revised in 2023 (COM(2023) 35) as A New Deal for Pollinators . The Initiative sets out objectives as well as long- and short-term actions under three priorities: i) Improving knowledge of pollinator decline, its causes and consequences; ii) Improving pollinator conservation and tackling the causes of their decline and iii) Mobilising society and promoting strategic planning and cooperation at all levels.
The Joint Research Centre (JRC), with the support of a pool of top pollinator experts, has been closely involved in the implementation of the EUPI since 2019, providing critical scientific input for developing methodological options for an EU Pollinator Monitoring Scheme (EU PoMS) and associated indicators. Two JRC technical reports have been published to date resulting from this work: “Proposal for an EU Pollinator Monitoring Scheme” (Potts et al. 2021) and “Refined proposal for an EU Pollinator Monitoring Scheme” (Potts et al., 2024).
The adoption of the Nature Restoration Regulation (NRR) in 2024 provided a new impetus to the setting up of an EU PoMS. Article 10 of the NRR stipulates that Member States shall reverse the decline of pollinator populations by 2030 and achieve thereafter an increasing trend. Article 10 foresees also the adoption of a standardised approach for collecting annual data on the abundance and diversity of pollinator species and for assessing pollinator population trends.
STING+ and new expert pool
To meet this renewed ambition, in the context of a new project named STING+, the JRC was tasked by the Directorate-General for Environment (DG-ENV) to mobilize high-level experts covering different aspects of the monitoring scheme to be set in place as well as the refinement of a pollinator indicator that should support the assessment of the legally binding target. For this, a new expert pool was established in 2024: SIMPOLL (Sampling strategy, Indicators and Monitoring methodology for EU POLLinators).
The specific objectives of SIMPOLL are:
- To enhance the methodological foundations of the EU PoMS, that will integrate the provisions of the NRR, particularly for what concerns:
- Indicators, power analysis and costs associated to capacity building and implementation
- Sampling strategy and methods
- To provide technical and scientific advice to the Commission and Member State authorities involved in the preparation and deployment of national pollinator monitoring schemes, in the context of the implementation of obligations under NRR’s Article 10.
DISCLAIMER: Until the adoption of the delegated acts established under the provisions of the articles 10, 21 and 22 of the NRR, the SIMPOLL experts are providing solely to the Commission their technical and scientific advice.
