National Habitat Creation Programme

Challenges and opportunities – delivering coastal squeeze compensation habitat in partnership

• Responsible for leading on the National Habitat

Creation Programme (NHCP)

• Delivering compensation habitat creation – in

partnership with authorities/organisations who share responsibilities for coastal squeeze

• Targets identified within the Shoreline Management

Plans

Compensatory measures are a must-have!

• Coastal protection plans – offset negative effects
• Maintain ecological coherence of the Natura 2000 network
• Mitigate for hydro-morphological pressures in HMWBs
• Offset adverse effects of sea level rise
• Coastal Squeeze: “squeezing” habitats against hard

surfaces maintained in the Shoreline Management Plans (SMP2’s) - HTLs

Compensate for coastal squeeze and adverse effects of sea level rise

Habitat Regulation Appraisals (HRA)

• f SMPs:
• Sea Level Predictions - UKCP09

(medium emission projection 95th %ile

• ~ 50-80cm rise over 100yrs (2105)

(BUT 93cm-1.9m plausible!)

The Scale of the Challenge

Designated site name Coastal Squeeze Intertidal Losses (Ha) - Wales By 2025 By 2055 By 2105 Total Severn Estuary SAC/SPA* 679 1388 3670 5737* Burry Inlet/Carmarthen Bay SAC/SPA 59 163 411 633 Pembrokeshire Marine SAC 2 4 5 11 Lleyn Peninsula and the Sarnau SAC 40 150 111 301 Anglesey Coast Saltmarsh SAC 1 4 11 16 Menai Strait and Conwy Bay SAC 3 12 1 16 Dee Estuary SPA 140 454 594 Total 784 1861 4663 7310

Severn Estuary SAC/SPA* = 1/3 in Wales

Compensation Habitat Creation for Carmarthen Bay SAC

• £43K/Ha
• £1.7M capital scheme
• SSSI
• Partnership with National Trust
• Managing coastal path issues - underway
• Project Appraisal Review (PAR) – underway
• 2017/18 – completion (subject to permissions)

Setting the scene for further compensation habitat creation schemes in:

• Carmarthen Bay SAC
• Anglesey Saltmarsh SAC
• Menai Strait Conwy Bay SAC
• Lleyn Peninsula & Sarnau SAC
• Pembrokeshire SAC
• Dee SAC
• Severn Estuary SAC

Conclusions

• Compensation requirements are large
• Risks are infraction (WG), capital and reputational
• Habitat creation is tricky & costly!
• NRW - good progress across the Natura 2000 series
• NHCP is an opportunity to work more effectively to create

N2K habitat ahead of SLR

• NRW is working towards partnership delivery of the

NHCP

Q: Partnership approach to compensation? vs. Q: LA reactive/project based approach?
