Justification for indicator selection
The effects of climate change on single species will have consequences for all levels of biodiversity, ranging from the genetic level to ecosystems. These higher-level impacts are of particular importance since biodiversity, besides being realised as a value in its own right, is increasingly acknowledged as providing indispensable ecosystems services for human well-being. Biodiversity can be regarded as ‘our collective life insurance’, as noted in the ‘EU biodiversity strategy to 2020’. The importance of wild species for the functioning of ecosystems is manifold and largely driven by biotic and abiotic interactions. An improved understanding of how climate change will affect these interactions in novel communities established under a novel climate can be utilised to assess the extinction risk of species of particular conservation concern. It will also enhance our abilities to assess and mitigate potential negative effects on ecosystem functions and services. Despite increasing knowledge about effects of climate change on pairwise species interactions and on complete ecological networks, quantitative assessments of these effects are still very uncertain. A robust conclusion from existing observational and theoretical studies is that specialist species are at much higher risk from effects on species interactions than generalist species.
Community changes triggered by climate change can lead to disruptions or alterations of currently existing species interactions and the generation of novel species interactions. Such changes impact on mechanisms such as competition, herbivory, predation, parasitism, pollination and symbiosis by affecting ecological matching among interacting species. These ecological matches can be defined by spatial or temporal synchronicity of occurrence, or by energetic, morphological and behavioural demands.
Climate change can also affect disturbance regimes, such as wildfires and storms. Forest fires is an important example of such a disturbance regime.

Policy context and targets
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.
No targets have been specified.

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 later. This webportal 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 will enhance the preparedness and capacity of all governance levels to respond to the impacts of climate change.
Key policy question
How is climate change affecting food networks and other species interactions, and what are the implications for biodiversity?
Methodology for indicator calculation
Ecological niche models (generalized linear models) for 36 European butterfly species and their larval host plants based on climate and land-use data were developed. The future distributional changes using three integrated global change scenarios for 2080 were projected. Observed and projected mismatches in potential butterfly niche space and the niche space of their hosts were first used to assess changing range limitations due to interacting species and then to investigate the importance of different ecological characteristics.

Data sets uncertainty
Available methods for incorporating species interactions, population dynamics and dispersal processes into models of range shifts are still very coarse, despite several recent approaches to incorporate these.
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/).
