This study tested the success of active revegetation techniques as a tool to promote functional and productive Treptacantha elegans forests in sea urchin barren grounds under different restoration strategies (active, and combined active with passive strategies).
Site Selection Criteria:
Six urchin barrens were selected for restoration, three inside a no-take marine reserve and three outside the reserve. Two forested sites and two urchin barren sites were used as reference sites.
Cause Of Decline:
Canopy forming algae play a key role in temperate coastal ecosystems, where they sustain complex habitats that provide food and refuge for biodiverse communities. These macroalgae are in decline in many coastal areas, where overgrazing by herbivores. and in particular sea urchins, can lead to the loss of these highly structured and diverse habitats towards less complex sea urchin barren grounds.
