Returning trees to the sea.
Marine TREES designs biodegradable reef structures that restore marine biodiversity, support fisheries, and strengthen coastal ecosystems by building with nature, for nature.
What are tree-reefs?
Made from sustainably sourced waste trees, tree-reefs support fish and a diversity of other marine organisms. As they break down over time, they release vital nutrients into the ecosystem, enhancing biodiversity and fostering a healthier marine environment.
​
By building structures from natural materials, we mimic historic reefs that have been lost - fostering the growth and rewilding of diverse marine communities. The importance of wood with marine systems has been undervalued - until now. We craft a balance between between human activities and environmental conservation. We are passionate about conserving and restoring aquatic life through sustainable practices, raising awareness, and actively engaging in meaningful partnerships for impactful restoration projects.

Applications

Reintroducing wood to the sea in the form of trees reconnects land and water, creating structure and shelter for marine life where it’s been lost.
Our tree-reefs mimic inputs of natural large wood to kickstart ecosystem recovery.
FISH & SHELLFISH
HABITAT RESTORATION

Wood-based reefs help reduce wave energy and trap sediment, stabilizing shorelines naturally. Our structures combine ecological function with physical protection —
nature-based defense in action.
COASTAL DEFENSE
Tree-reefs provide essential complexity and refuge for fish to feed, grow, and lay eggs. By restoring lost underwater architecture, we boost biodiversity and support local fisheries from the bottom up.
FISH PRODUCTION


OFFSHORE ENERGY
Artificial reefs beneath offshore energy installations offer crucial habitat enhancement by creating elevated, complex structures on the seafloor.
Integrating reef structures helps boost local biodiversity and supports the development of balanced, resilient ecosystems around offshore infrastructure.
AQUACULTURE
By introducing tree-reefs around aquaculture operations, we create stable habitat and enhance local food webs, attracting larger predatory fish that help maintain ecological balance.
Structural complexity also provides shelter for juvenile fish and forage species, indirectly supporting aquaculture through natural ecosystem services.

ECOTOURISM
Tree-reefs reefs create vibrant underwater habitats that attract fish and invertebrates, making them ideal destinations for divers and snorkelers. These installations not only enhance marine biodiversity but also support sustainable recreational activities such as diving and recreational fishing.
