Understanding the likely scale of deterioration of Marine Protected Area features due to coastal squeeze: Part 2
To complete the coastal squeeze assessments a series of geospatial layers and accompanying spreadsheets were created as part of a project to understand the likely scale of deterioration of Marine Protected Area features due to coastal squeeze.
Coastal squeeze and natural squeeze was calculated for habitats at a national scale for the whole of the Welsh coastline, as well as for smaller delineations of the coastline. The potential scale of habitat deterioration due to coastal squeeze was then reported:
· Nationally;
· Against individual MPAs; and
· Against MPA designations amalgamated across Wales:
o SACs;
o SSSIs;
o SPAs; and
o Ramsar sites.
Coastal squeeze has been assessed for three timeframes (epochs):
· 2025 to 2055 (30 years) – Equivalent to SMP2 medium-term epoch;
· 2055 to 2105 (50 years) – Equivalent to SMP2 long-term epoch; and
· 2105 to 2155 (50 years) – New long-term epoch.

The project applies standard predictive hypsometric analysis to calculate the changes in tidal frame around the Welsh coast as a result of SLR. These tidal frames are calculated from a newly created national Digital Terrain Model (DTM). Present-day habitat maps are then used to provide a more site-specific assessment of the habitats present, and hence how they may change over time. Further information on the habitat datalayers used in the assessment can be found in the Volume 1 Report.
The coastal squeeze and natural squeeze assessments are then undertaken. The quantification of coastal squeeze and natural squeeze is calculated:
· Nationally;
· Against SMP2 Policy Unit (PU); and
· Against individual Assessment Units.
In each case, coastal squeeze and natural squeeze is calculated for defined Habitat Groups (see Section 2.2). An assessment of coastal and natural squeeze across the MPA network has then been undertaken. The potential scale of deterioration of MPAs due to coastal squeeze is reported against:
· Individual MPAs; and
· MPA designations amalgamated across Wales:
o SACs;
o SSSIs;
o SPAs; and
o Ramsar sites.
The derived data products are vast and complex and to help users assess and interpret the data they should review section 6 of the accompanying report which will highlight frequently encountered observations.
