“…Assemblages associated with mussel beds on artificial structures (pontoons, seawalls and pilings) differed from those on natural reefs (People 2006). Also, the abundances and composition of epibiotic assemblages on kelps on pier pilings or marinas differed from those on natural reefs (Marzinelli et al 2009;Johnston et al 2011).…”

“…For example, pilings and pontoons in Sydney Harbour supported approximately twice the amount of non-indigenous species than natural reefs (Glasby et al 2007). It appears therefore that artificial structures are entry points for non-indigenous species (see eg Bulleri and Airoldi 2005;Arenas et al 2006;Glasby et al 2007;Ignacio et al 2010), enhancing their spread and establishment independently of whether they occur on primary or secondary substrata (Johnston et al 2011). This, in turn, can have serious consequences on local diversity and function.…”

“…The introduction of artificial structures, such as seawalls, marinas and breakwaters, increases the local production of fouling assemblages and artificial habitats support assemblages different from those in many natural habitats (Connell and Glasby 1999;Glasby 1999a;Arenas et al 2006). Further, many non-indigenous species live directly on artificial hard-structures that provide novel substrata (eg Hewitt et al 2004;Bulleri and Airoldi 2005;Glasby et al 2007), although non-indigenous species also occur on biogenic habitats on artificial structures (Johnston et al 2011).…”

“…Many species do not occur directly on primary substrata, but on other organisms (secondary or biogenic habitat) that live on artificial habitats (eg Ryland 1962;People 2006;Marzinelli et al 2009). The effect of modification of habitat on biota living in biogenic habitats on artificial substrata is poorly understood (People 2006;Marzinelli et al 2009;Johnston et al 2011).…”

Artificial structures influence fouling on habitat-forming kelps

The addition of artificial structures along urbanised shorelines is a global phenomenon. Such modifications of habitats have important consequences to the abundance of fouling organisms on primary substrata, but the influence on fouling of habitat-formers living on these structures is poorly understood. Fouling of habitat-forming kelps Ecklonia radiata on pier-pilings was compared to that on rocky reefs at three locations in Sydney Harbour. Kelps on pilings supported different assemblages of bryozoans from those on reefs. The abundances of bryozoans on kelps, in particular of the non-indigenous species Membranipora membranacea, were significantly greater on pilings. Differences were consistent in time and space. This indicates that the addition of artificial structures also affects fouling on secondary biogenic substrata, altering biodiversity and potentially facilitating the introduction and dispersal of non-indigenous epibiota. Understanding the processes that cause these patterns is necessary to allow sensible predictions about ecological effects of built structures.

“…In a well-flushed system, these contaminants might be dispersed, but many marinas that are surrounded by an artificial breakwall are specifically designed to restrict water flow [22,23]. This often results in a higher localised impacts as contaminants become bound to the sediments and localised effects to ecological communities [24,25]. …”

Sediment Contaminants and Infauna Associated with Recreational Boating Structures in a Multi-Use Marine Park

et al. 2015

Multi-use marine parks achieve conservation through spatial management of activities. Zoning of marine parks in New South Wales, Australia, includes high conservation areas and special purpose zones (SPZ) where maritime activities are concentrated. Although such measures geographically constrain anthropogenic impacts, we have limited understanding of potential ecological effects. We assessed sediment communities and contaminants adjacent to boating infrastructure (boat ramps, jetties and a marina) in a SPZ from the Clyde Estuary in Batemans Marine Park. Metal concentrations and fines content were elevated at boating structures compared to reference sites. Species richness was higher at sites with boating structures, where capitellid polychaetes and nematodes dominated the communities. Changes associated with boating structures were localised and did not extend beyond breakwalls or to reference sites outside the SPZ. The study highlights the benefits of appropriate zoning in a multi-use marine park and the potential to minimise stress on pristine areas through the application of spatial management.
