1. Coastal sand dunes are widespread worldwide, including around the coasts of the British Isles and Europe, providing a wide range of functions some of which are recognized for their socio-economic benefits. 2. In some localities, their contribution to coastal defence and to tourism and regional character have been acknowledged in local plans, but this is far from ubiquitous. 3. A rapid assessment was undertaken of the range of ecosystem services provided by coastal sand dune systems, using the Millennium Ecosystem Assessment ecosystem services classification augmented with habitatand locally-appropriate additions. 4. Sand dunes were shown to provide a wide range of provisioning, regulatory, cultural and supporting services, many of which remain substantially overlooked. 5. Although the importance of coastal sand dune for a diversity of characteristic and often rare organisms from a variety of taxa has been addressed, many of the broader ecosystem services that these habitats provide to society have been overlooked. This suggests that coastal sand dune systems are neglected ecosystems of significant and often under-appreciated societal value. Copyright © 2010 John Wiley & Sons, Ltd. Source

A flashing strip can include a body and at least one reinforcing member. The flashing strip can include a viscoelastic body deformable by a manual force between at least a first configuration and a second configuration. The flashing strip can also include at least one reinforcing member being deformable by the manual force. The reinforcing member can be configured to maintain a first shape of the body when the body is in the first configuration and when the manual force is not applied to the body and can be configured to maintain a second shape of the body when the body is in the second configuration and when the manual force is not applied to the body.


Disclosed is a surface relief structure. The structure includes a recording medium configured to be structurally modified when exposed to interfering and non-interfering portions of radiation beams, the structurally modified recording medium including, when viewed in a two-dimensional cross-section along one of the axes of the recording medium a plurality of equally spaced steps of fine-sized periodicity superimposed upon a plurality of deep depressions of substantially coarse-sized periodicity. The structurally modified recording medium is configured to produce in reflection single and multiple colors in a broad spectral range when illuminated by a source of light.
