Biodiversity Monitoring and Assessment

According to the 2019 Global Assessment by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), around one million animal and plant species are threatened with extinction worldwide. Human activities are degrading ecosystems at an unprecedented rate, undermining food security, climate resilience, and access to clean air, water, and soils – ultimately threatening the foundations of human well-being.

The World Economic Forum’s Global Risks Reports consistently highlight how environmental degradation, alongside geopolitical and societal challenges, is increasingly impacting on socio-economic systems. Since 2006, environmental risks have intensified in both frequency and severity. Biodiversity loss and ecosystem collapse are now among the most critical long-term global risks.

In response, the Kunming-Montreal Global Biodiversity Framework (GBF), adopted at the 15th Conference of the Parties to the Convention on Biological Diversity in 2022, sets ambitious targets for 2030 and 2050 to achieve a world living in harmony with nature. These commitments are reflected at European and national levels, including the EU biodiversity strategy for 2030 and Luxembourg’s National Nature Protection Plan (PNPN3).

Through close collaboration with national stakeholders and European partners, the BIODIV group coordinates large-scale monitoring programmes, with a focus on:

• Tracking the conservation status of protected species under EU directives (e.g. Water Framework Directive, Habitats Directive)
• Assessing ecosystem health through the monitoring of key taxonomic groups (e.g. wild pollinators, forest mammals, freshwater invertebrates, diatoms)
• Detecting and documenting the spread of invasive alien species
• Developing innovative technologies for biodiversity data collection, processing and analysis

These monitoring efforts rely on structured sampling designs and standardized protocols across long-term observation sites, ensuring high-quality datasets that enable robust statistical analyses and reliable trend detection.

As a national coordinator of biodiversity monitoring in Luxembourg, the BIODIV group plays a central role in:

• Reporting on species conservation status
• Updating red lists and producing distribution atlases
• Developing biodiversity indicators
• Supporting early warning systems for biological invasions 

The group also contributes to international knowledge exchange, sharing data and expertise beyond Luxembourg.

To enhance monitoring capacity, BIODIV integrates traditional field methods with cutting-edge technologies. Automated devices such as camera traps and acoustic recorders improve detection of elusive species, while molecular tools (e.g. environmental DNA and metabarcoding) enable efficient assessment of biodiversity in aquatic and soil ecosystems. Citizen science initiatives further expand data collection across the country.
