Climate change scenarios for the region
The workpackage compiles and presents general, regional and site specific information on climate change scenarios, based on existing General Circulation Model (GCM) simulations, and on downscaling experiments ? both dynamic (through regional climate models), and empirical. The primary selection of GCMs are the five selected by the Arctic Climate Impact Assessment (ACIA). The focus is on temperature and precipitation, with discussions on wind, snow cover, and runoff. The Workpackage cooperates with the workpackage dealing with climate trends on snow cover change scenarios.

The aim of this work package is to perform a regional assessment of climatic variability from different sources at each of the SCANNET sites. We will identify and analyse detailed climate parameters (and proxies) other than long term means, relevant to various environmental change impacts such as phenology, winter damage to vegetation, etc.

The aim of this work package is to compile and present regional and site specific information on biodiversity at different levels. Baseline information on habitat and species diversity is assessed and presented at different spatial levels from sites to natural historic provinces. The often low species diversity at SCANNET sites is due to climatic severity, spatial isolation and recent deglaciation. However, some taxa (e.g., waders, sawflies) show relatively high species diversity in northern areas. Intraspecific variability and active speciation are frequent phenomena in the area. Assessment of the diverse baseline information on habitat richness and species diversity will precede improvement in standardization and comparability of observations. Check lists for major groups (birds, vascular plants, lichens) have been compiled and selected invertebrate groups are now addressed (Lepidoptera, Carabidae, Aquatic insects).

Phenology and species performance
The main aim is the construction of a meta database of monitoring data from field stations and adjacent sites. By compiling information from a large number of studies we will produce a unique review of existing long-term data series on terrestrial species. This will benefit a broad suite of user groups by identifying gaps and proposing protocols for future monitoring projects.

Stakeholders perception of environmental change
The aim is to involve local stakeholders in identifying the priority environmental concerns at each SCANNET site and then to prioritise key indicators of change that could be used for monitoring. The approach is to hold decision workshops with stakeholders in which a wide raft of ecological, social and economic issues and indicators are ranked and compared. A standard protocol is used at all sites so that the results can be compared across the network.
