Cavities

Cavities provide increased surfaces which are sheltered. This could improve oyster larvae settlement and sediment accumulation.

Artifical oyster reefs constitute a key part of the transitional park, forming the second line of defense for the seagrass meadows and inner harbor.

The concrete reef units were designed with the intention of maximising the probability of succesful oyster larvae attachement by increasing the available surface area, while providing verticality and sheltered spaces. The textured surface provides additional opportunities for organisms to attach.

As new larvae attach to old oyster shells, the oyster reef will gradually increase in height. The artificial reef units will contribute to this by providing an immeditate vertical presence which will allow larvae to more easily attach on the textured surface and increase with sediment retention. The recycled concrete will be mixed with an eco-mix of concrete provided by Econcrete, to improve it’s compatibility with marine flora and fauna.

Texture

Textured surfaces increase biodiversity allowing a more vaired range of organisms to attach and establish

The natural shapes formed by lichen and fungi inspired the the design for the reef units. Features such as the bowl shaped protrusions known as apothecia translate well to a underwater reef context where tubulent currents may disrupt larval settlement (or any other organisms) making sheltered sites desireable.

Concave Structures

The concave form of lichen apothecia increase surface area while protecting the inner portion

Organic Shapes

Lichen feature various protrusions, folds and cracks which create habitats for other microorganisms to inhabit
