Biodeterioration and bioprotection of concrete assets in the coastal environment
The deleterious effects (biodeterioration) and the protective benefits (bioprotection) of biological colonisation on
manmade structures have long been debated. Lichens, biofilms, algae, bivalves and gastropods contribute both
directly and indirectly to damaging substrata in the coastal zone which can enhance abiotic erosive forces that
exploit biologically induced superficial damage. There is mounting evidence that these same species may also
provide protective benefits. This debate often impacts approaches to managing fouling on concrete assets in the
coastal environment. The net benefit or detriment a species or assemblage has on a structure is spatially and
temporally dynamic and subject to the influence of various abiotic and biotic factors at different scales. However,
the net outcome may be more pronounced under different contexts, particularly under warming and ocean
acidifying climate change scenarios which is where further research should focus. Additionally, as bioprotection
represents a potentially valuable ecosystem service, it supports the argument for increasing and improving
habitat availability and biodiversity on artificial coastal structures via ecological enhancement. Quantifying
bioprotection in useful metrics, such as monetary value or time added to serviceable life, would help demonstrate
the benefits of bioprotective species in a meaningful wa
