Indicator Specification
Species interactions
Rationale
Justification for indicator selection
The impacts of climate change on single species can lead to disruptions or alterations of currently existing species interactions such as competition, herbivory, predation, parasitism, pollination and symbiosis. These interactions are affected because different species adapt their phenology (i.e. the timing of annual events) and their distributional range differently in response to climate change. Climate change can also affect disturbance regimes, such as wildfires and storms. These higher-level biodiversity 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’.
An improved understanding of how climate change will affect species 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.

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 isBetter informed decision-making, which should occur throughBridging the knowledge gap andFurther developing Climate-ADAPT as the ‘one-stop shop’ for adaptation information in Europe. Further objectives includePromoting action by Member States andClimate-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
-
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.

Uncertainties
Methodology uncertainty
Not applicable
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/).
