Chapter 4: Healthy and Biologically Diverse

The Scottish Wildlife Trust (SWT) manages a large number of reserves throughout Scotland. Many of these reserves are located in coastal areas. This layer shows the locations of the SWT reserves in Scotland.

Group layer containing EUSeaMap 2023 classified to the EUNIS 2019 Classification system with simplification levels of 200m, 400m and 800m simplification for fast WMS viewing at all scales. Output of the 2023 EUSeaMap broad-scale predictive model, produced by EMODnet Seabed Habitats in the EUNIS 2019 classification. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the north. The map was produced using a "top-down" modelling approach using classified habitat descriptors to determine a final output habitat. Habitat descriptors differ per region but include: Biological zone Energy class Oxygen regime Salinity regime Seabed substrate Riverine input Habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced using R and Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 metres). The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale.
