The value of citizen science monitoring for biodiversity
Invasive alien species pose greater risks than previously thought for biodiversity, human health and economies, according to two new reports from the European Environment Agency (EEA).
Part B focuses on emerging lessons from the degradation of natural systems and their wider implications for society - booster biocides, the pill and the feminisation of fish, climate change, floods, insecticides and honeybees as well as ecosystem resilience more broadly.
Biological invasions are one of the main drivers of biodiversity loss. Invasive alien species (IAS) may have far-reaching and harmful effects on the environment and natural resources for generations. The purpose of this report is to raise awareness among key stakeholders, decision-makers, policymakers and the general public about the environmental and socioeconomic impacts of IAS. Twenty-eight dedicated species accounts are provided to highlight the various types of impacts. These species accounts are based on thorough, up-to-date scientific information from recent research and studies, and highlight the multifaceted impacts of IAS at both the global and regional levels.
To support the 'Streamlining European 2010 Biodiversity Indicators' (SEBI 2010) process, the European Environment Agency (EEA) commissioned a study to revisit and further develop the indicator 'Invasive alien species in Europe'. The aim of the current project is to critically review and improve this indicator, and propose an updated methodology. Further, options for methodologies of new indicators, which monitor IAS over time across Europe, will be discussed. Particular attention is given to closely linking the indicator(s) to recent biodiversity policy goals and developments.

This figure shows spatial mismatches of the Portuguese Dappled White butterfly (Euchloe tagis) and its host plants under the BAMBU scenario (climate: A2) for 2050-2080. Green, suitable climate space for the host plants;orange, suitable climate space for the butterfly; red, suitable area for both butterfly and host plants; open circles, currently observed distribution.
