Rationale

Justification for indicator selection

Climate change affects ecosystems in complex ways. The composition of many plant communities is changing, often to such an extent that completely new assemblages are appearing. The extinction risk is particularly large at the trailing edge (i.e. southern or lower altitudinal range margins) of a species. The ecological implications of these changes and their effects on the provision of ecosystems services are difficult to assess and quantify. However, it is clear that climate change is an important threat for long-term biodiversity conservation. It threatens the ability of meeting the EU policy target to halt biodiversity loss by 2020. The favourable status of Natura2000 sites is also in danger.

Policy context and targets

Context description

In April 2013 the European Commission presented the EU Adaptation Strategy Package (http://ec.europa.eu/clima/policies/adaptation/what/documentation_en.htm). This package consists of the EU Strategy on adaptation to climate change /* COM/2013/0216 final */ and a number of supporting documents. One of the objectives of the EU Adaptation Strategy is Better informed decision-making, which should occur through Bridging the knowledge gap and Further developing Climate-ADAPT as the ‘one-stop shop’ for adaptation information in Europe. Further objectives include Promoting action by Member States and Climate-proofing EU action: promoting adaptation in key vulnerable sectors. Many EU Member States have already taken action, such as by adopting national adaptation strategies, and several have also prepared action plans on climate change adaptation.

The European Commission and the European Environment Agency have developed the European Climate Adaptation Platform (Climate-ADAPT, http://climate-adapt.eea.europa.eu/) to share knowledge on observed and projected climate change and its impacts on environmental and social systems and on human health; on relevant research; on EU, national and subnational adaptation strategies and plans; and on adaptation case studies.

  Adaptation means anticipating the adverse effects of climate change and taking appropriate action to prevent or minimise the damage they can cause, or taking advantage of opportunities that may arise. It has been shown that well planned, early adaptation action saves money and lives in the future. This web portal provides information on all adaptation activities of the European Commission.
• EU Adaptation Strategy Package
  In April 2013, the European Commission adopted an EU strategy on adaptation to climate change, which has been welcomed by the EU Member States. The strategy aims to make Europe more climate-resilient. By taking a coherent approach and providing for improved coordination, it enhances the preparedness and capacity of all governance levels to respond to the impacts of climate change.

Methodology

Methodology for indicator calculation

A combination of an integrated environmental model (IMAGE) and climate envelope models for European plant species is used for several climate change scenarios to estimate changes in mean stable area of species and species turnover.

Uncertainties

Methodology uncertainty

Not applicable

Data sets uncertainty

Species distribution models (also known as habitat models, niche models or envelope models) suffer from a variety of limitations because species are currently not in equilibrium with climate, and because species dispersal and biotic interactions are largely ignored. Furthermore, climate change projections for Europe include climate conditions (in particular in southern Europe) for which no analogue climate was available for the model calibration. Especially the latter problem is evident for projections for southern Europe since projections of species distribution models lack information from climates south of the Mediterranean. Therefore, the uncertainty in the Mediterranean region is much higher and projected declines might result from a lack of data from climatic situations not included in the model.

Further information on uncertainties is provided in Section 1.7 of the EEA report on Climate change, impacts, and vulnerability in Europe 2012 (http://www.eea.europa.eu/publications/climate-impacts-and-vulnerability-2012/)
