The historic boardwalk offers an opportunity to rethink today's beach's monoculture through a more organic boardwalk form and topographic section that have a new relationship to beachside development and promotes a healthier ecology (see Figure 12.7). The shape and design of the boardwalk can maintain its important social role while providing a new infrastructure to capture sand and form dunes over time, creating protection and habitat area for beach wildlife. Microtopography could support a variety of plant species and nesting sites for beach breeding bird species, such as Piping Plover and Roseate Terns. Swales can be dug for ponding which supports invertebrates used by these bird species (Maslo et al., 2011, 2012). Segments of boardwalk can be redesigned to include more experimental dune/habitat creation strategies, protecting the community and acting as a new park. In spatially constrained sections, the boardwalk-dune design will consider a “compressed dune” typology, which includes a newly forming dune, tidal pool, and primary dune (Sasaki et al., 2015).
Management strategies within a marine spatial planning framework
Published in Peter B. Myles, Maritime Clusters and the Ocean Economy, 2017
Physical approaches to management are those human-made structures that control human activity by restricting the movement or type of activity which can be undertaken. A typical marine example is the construction of a boardwalk across a wetland. This physical structure directs and facilitates the movement of tourists and reduces the negative impacts that could be caused by their walking through sensitive areas. Due to the difficulties involved with erecting structures in the marine environment, physical controls are not a particularly common system in controlling marine tourism. In a number of situations, physical structures have been successfully used to control tourists in the sea, for example, the use of mooring buoys to reduce anchor damage on coral reefs. Additional examples include the use of glass-bottom boats, semi-submersibles, self-guided underwater trails and beach bicycle pathways.
Unmanned aerial remote sensing of coastal vegetation: A review

A general sUAS related challenge described in the literature includes the presence of artefacts in the imagery, created during orthomosaic generation, which can make classifications difficult (Samiappan et al. 2016). ‘Artifacts’ can be described as blurred objects or discontinuities in the orthomosaicked images. For example, a boardwalk in a section of marsh may be blurred out or slightly misaligned during the mosaicking process. The misalignment or blurring of the object can cause misclassifications. Discontinuities can be different across datasets from the same area, which can make change detection difficult.
