Queen’s Marque Installs Reef Balls to Foster Healthy Ecosystem

Queen’s Marque has released five reef balls into the Halifax Harbour as a preemptive measurement to offset any potential impact construction could have on the harbour. Reef balls, designed by The Reef Ball Foundation and manufactured by Nova Scotia’s Clean Foundation, create and restore marine habitat by fostering the growth of an ecosystem that supports fish and shellfish populations.

When deployed into Nova Scotia’s marine environment, reef balls support the growth of algae, which is a foundational piece in the ecosystem, and provide shelter and protection to fish species. They also serve as habitats for spawning and reproduction, which aides in maintaining a healthy marine population. The reef balls selected by the Queen’s Marque design team do not leach toxins into the water and do not contain biologically active compounds.

As part of the project the Clean Foundation has installed five reef balls on behalf of Queen’s Marque, which equates to 900 square metres of marine habitat.

In addition to improving local harbour conditions, the reef ball initiative helps raise public awareness of Nova Scotia’s ocean environment. The goals of the Clean Foundation align with Queen’s Marque, as planning for a Gentle Footprint and having the utmost respect for Nova Scotia waters is a fundamental value of the project.
