A major part of this is to counteract the negative impacts of habitat fragmentation (reduction in are and increase in isolation). Modelled habitat networks can provide insights into how landscapes are likely to be functioning and inform the location of actions to improve the connectivity and resilience of protected sites. This is a spatial dataset consisting of maps of habitat networks originally developed by Countryside Council for Wales (CCW) in collaboration with Forestry Commission Wales and Forest Research using a functional networks approach, and now managed and progressively developed by NRW. Patches of habitat and other intervening habitats through which many of their species are able to move are mapped as habitat networks. Networks have been mapped for habitats including woodland, unimproved grassland, calcareous grassland, marshy grassland, heathland, fens and bogs; in most cases these are divided into upland and lowland versions and in some cases networks that support the highest quality areas of habitat have been selected out as priority layers. Results are available for the whole of Wales as GIS layers and include three levels of habitat networks; core networks (areas within which species that require extensive habitat and disperse poorly are able to move), focal networks (areas within which species tolerant of smaller habitat patches and with greater dispersal ability are able to move), and local networks (areas within species that can persist within small habitat patches and have very limited dispersal abilities can move). These habitat networks also form the basis of ‘Priority Ecological Networks’ (PENs), a subset of the ‘focal’ networks described above which have been selected against our suite of Protected Sites. Purpose of data capture was to allow the scope and range of potential networks to be rapidly explored. Predicted habitat networks can be used to guide large-scale planning for nature conservation, provide insight into how the landscape is likely to be functioning and prioritise action to improve the connectivity and viability of protected sites. Layers are arranged in two folders: Level 1, containing all outputs across Wales, and Level 2 which are selected, priority networks, within which action may be targeted to enhance functional networks of the best habitat areas.

The model is based on species characteristics, taking into account a minimum habitat area and the relative ecological cost of different habitats. It relates to ease of movement through different land cover types, expressed in terms of dispersal distance in metres over a 50 year timescale. In simple terms it draws a 'buffer' around habitat patches, the width of which depends upon the assumed permeability of the intervening habitats. When buffers around patches overlap the habitat patches are considered to be part of the same habitat network with many species potentially able to move between all habitat patches within it. This project uses data from Phase 1 Habitat Survey of welsh woodlands, grasslands, heathlands and bogs and fens, supplemented with National Forest Inventory data for woodland.
