  • In the majority of European seas, the Marine Trophic Index (MTI) has been declining since the mid 1950s, which means that populations of predatory fish are declining and populations of smaller fish and invertebrates are increasing; this indicates that fisheries are not exploiting the resources sustainably (EEA, 2009).
  • There are significant differences in the decline in MTI rates in the different seas (EEA, 2009).

Assessing biodiversity in Europe — the 2010 report The present report considers the status and trends of pan-European biodiversity, and the implications of these trends for biodiversity management policy and practice. It considers the key biodiversity policy instruments currently applied in Europe, the threats to biodiversity and their management implications across major habitat types. The implications for biodiversity of cross-cutting issues such as tourism and urban planning are also considered, along with the challenges that remain for conserving and sustainably using of Europe's biodiversity. The report makes use of the SEBI 2010 indicators and other relevant national and regional information sources. It does not consider the biodiversity of EU overseas territories and outermost regions.
EU 2010 Biodiversity Baseline The EU 2010 Biodiversity Baseline provides facts and figures on the state and trends of the different biodiversity and ecosystem components. It thereby supports the EU in developing the post‑2010 sub‑targets and provides factual data for measuring and monitoring progress in the EU from 2011 to 2020.
Progress towards the European 2010 biodiversity target This report presents a first indicator-based assessment of Europe's progress towards its target of halting biodiversity loss by 2010. The Streamlining European 2010 Biodiversity Indicators (SEBI 2010) process was set up to streamline national, regional and global indicators and, crucially, to develop a simple and workable set of indicators to measure progress and help reach the 2010 target.
