Metadata: Marine Invasive Non-Native Species (INNS) Pathways Heatmaps for Wales 2020
Abstract:
Heatmaps (geodatabases) were created for invasive non-native species pathways in Welsh waters including commercial shipping, recreational boating, aquaculture, fishing and offshore activities. Heatmaps were produced at both 2km x 2km and 5km x 5km resolutions and have associated symbology layers. An overall heatmap was also produced to highlight key areas which are likely most at risk from invasion of invasive non-native species. This assessment provides a valuable insight into hotspots related to each potential pathway of introduction, the areas where the main areas of risk overlap for the different pathways and their overlap with protected areas. The outputs from this assessment can form the basis to underpin biosecurity planning. It should be noted, however, that this was a national scale mapping exercise based only on freely available datasets, which themselves have limitations and possible inaccuracies due to incomplete coverage, both temporally and spatially. The scorings applied to the input datasets and weightings applied to the introduction pathways are also based on available literature and expert judgement. Site-specific activities and conditions will always be an important consideration, as well as temporal variations.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The approach applied in this study, used data acquired from readily available, open licence sources where possible. A hexagonal grid, clipped to the extent of the Welsh marine planning area, with cell size of 5 km2 was created in ArcGIS and this was spatially joined to input data layers, representative of the introduction pathways, to create heatmaps. A series of heatmaps were created for each of the introduction pathways, using a scaled scoring method. A final combined heatmap of all introduction pathways was also created by applying weightings to the different pathways. Figures of all heatmaps were created, as well as figures of designated sites overlying the final combined heatmap to show sites at potentially greater risk from the introduction of marine INNS. The Celtic Sea (including Welsh and Irish waters) has approximately two to three new introductions of non-indigenous species every year (European Environment Agency (EEA), 2015; 2019a). Identifying coastal areas where invasive non-native species (INNS) are more likely to be introduced is a valuable tool which will help to focus management efforts and identify sensitive areas which may be at a higher risk. Mapping the intensity of introduction pathway activities can aid the identification of these higher risk areas. This associated report provides an update to the work carried out by Tidbury et al. in 2014, which considered the potential for the introduction of INNS in coastal areas of UK and Ireland using a 50 km x 50 km grid. This study focuses only on Welsh waters and at a higher spatial resolution than the original study. |
