Indicator Specification
Climate warming affects the life-cycles of all animal species. Species adapted to warmer temperatures or dryer conditions may benefit from this change, whereas cold-adapted species may encounter increasing pressure on their life-cycles. Mild winters and the earlier onset of spring allow for an earlier onset of reproduction and, in some species, the development of extra generations during the year. In the case of a phenological decoupling between interacting species in an ecosystem (e.g. reduced pressure from parasitoids and predators), certain populations may reach very high abundances that attain orexceed damage thresholds in managed ecosystems (e.g. bark beetles in conifer forests). Desynchronisation of phenological events may also directly reduce fitness, for example if shortened hibernation times deteriorate body condition or if interactions between herbivores and host plants are lost. It may also negatively affect ecosystem services such as pollination. There is robust evidence that generalist species with high adaptive capacity are favoured, whereas specialist species will be mostly affected negatively.
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.

The trend in laying date between 1980 and 2004 for most of the European breeding areas is simulated by combining geographical variation in mean laying date, the effect of temperature on laying date, and spatial variation in temperature change. Breeding dates of pied flycatchers were taken from the review by Sanz (1997), supplemented with some data from Russia (Both et al. 2004). Only data from latitudes higher than 48°N were used.

Generally, observations for popular groups such as vascular plants, birds, other terrestrial vertebrates and butterflies are much better than for less conspicuous and less popular species. Similarly, due to extensive existing networks, a long tradition and better means of detection and rapid responses of the organisms to changes, knowledge on phenological changes are better observed and recorded than range shifts. Projections of climate change impacts on phenology rely crucially on the understanding of current processes and responses. For most cases, only a few years of data are available and do not cover the entire area of the EU but are restricted to certain well monitored countries with a long tradition in the involvement of citizen scientists. Based on these short time series, the determination of impacts and their interpretation thus has to rely on assumptions, and achieving a qualitative understanding of species’ responses is more robust than their quantification. One of the greatest unknowns is how quickly and closely species will alter their phenology in accordance to a changing climatic regime. Even experimental studies seem to be of little help, since they notoriously tend to underestimate the effects of climate change on changes in phenology.
