一个基于地理信息系统的方法已被用来评估现有的和潜在的不久的将来的沿海生境在不同的海平面上升和管理方案。对于六个当地的案例研究，在英国南部海岸，在满足个别案例研究领域内的欧盟委员会海洋生物指令的要求的困难被发现。最重要的问题是有关的潮间带盐沼和泥滩地区，下降的所有海平面上升的情况下考虑。在一些地方，对这些损失的补偿可以通过有管理地重新调整海防来创建替代栖息地来实现，通常与工程沉积物供应相结合，将潮间表面提高到有利于植被建立的水平。然而，历史上的土地使用决定将在许多地区限制这种做法。特别是，有管理的重新调整将导致沿海放牧沼泽的减少，这也是该指令指定的生境。然而，在更广泛的规模存在的潜力，以补偿失去的沿海放牧沼泽与河流放牧沼泽在毗邻的河流集水区。空间规划为这些地区未来的土地储备提供了潜力，但其实施可能需要重新解释《土地储备指令》的适用。
A GIS-based approach has been used to assess existing and potential near-future coastal habitats under different sea-level rise and management scenarios. For six local case studies on the south coast of the UK, difficulties in meeting the requirements of the EC Habitats Directive within individual case study areas were found. The most significant issues were related to intertidal saltmarsh and mudflat areas, which decline under all the sea-level rise scenarios considered. Compensation for these losses in some localities could be achieved through the creation of replacement habitat by the managed realignment of sea defences, often in conjunction with engineered sediment supply to raise intertidal surfaces to levels conducive to vegetation establishment. However, historic land use decisions will restrict this approach in many areas. In particular, managed realignment will lead to a decline in coastal grazing marsh, also a designated habitat under the Directive. However, at wider scales potential exists to compensate for lost coastal grazing marsh with fluvial grazing marsh in adjoining river catchments. Spatial planning offers the potential for future landbanking of these areas, but its implementation may require a reinterpretation of the application of the Habitats Directive.
