CSGN - Integrated Habitat Networks
The approach employs a detailed desk study using digital data within a geographic information system (GIS) to identify Integrates Habitat Networks (IHNs). The spatial position and extent of functional integrated habitat networks were determined through a landscape ecology model from the BEETLE (Biological and Environmental Evaluation Tools for Landscape Ecology) suite of tools. The BEETLE least-cost focal species approach negates the need to carry out a vast number of individual species analyses. The selection of the habitats to be modelled, and the species used to inform the analysis, were identified through a series of expert stakeholder workshops. The outputs can support the planning process, help prioritise conservation effort, prevent further fragmentation of biodiversity and aid connectivity of semi natural habitats. BEETLE model analysis has been well referenced (Watts et al., 2005) and used in a variety of projects such as developing forest habitat networks across Scotland. The application of IHNs is the first time that the multiple habitat network approach has been used to solicit planning and development programmes in key areas.

A landcover was created using OSMasterMap, available phase1 and NVC data and the Forestry Commissions' Native Woodlands Survey of Scotland. A Delphi process was carried out to ascertain the resistance of the different landcover types, edge effect and minimum core habitat of each of the network types and the dispersal distances. Delphi is a structured process. The questionnaires are sent to a pre-selected group of experts who anonymously rank their preferences. Delphi is characteristically repetitive with experts being consulted at least twice so that they can reconsider their original answers in light of information they receive from the other experts during the controlled feedback. Questions are formulated so that answers can be processed quantitatively. Each of the iterative consultations is called a round and rounds continue until stable responses between rounds are achieved. All opinions are aggregated to form part of the answer. Group interaction is anonymous to avoid the potential of individual expert opinions being unduly influenced by the personalities or status of other participating experts while controlled feedback is mediated by coordinator(s) so that irrelevant information is removed from the process (Landeta, J. 2006. "Current validity of the Delphi method in social sciences" Technological Forecasting & Social Change 73:467-482., Novakowski, N. and Wellar, B. 2008. "Using the Delphi technique in normative planning research: methodological design considerations", Environment and Planning A, 40:1485-1500). In addition to the dispersal distances derived from the Delphi process all networks were also run at 2km as a maximum dispersal event and to allow for comparability both between networks and with earlier versions of the analysis.
