Restoration Objective:
This study aimed to determine biotic factors that may be limiting local recolonisation of Lessonia along the northern Chilean coast. Specifically, it aimed to determine whether encrusting coralline algae limits the recruitment of Lessonia, and the mechanisms by which it does so.
Site Selection Criteria:
Sites were selected along the northern Chilean coast, where Lessonia is still present in some areas. Quadrats were installed in the intertidal zone where Lessonia normally occurs.
Cause Of Decline:
A strong El Niño event in 1982-1983 caused local extinction in populations of the low intertidal kelp Lessonia nigrescens on northern Chilean coasts. The kelp has partially recolonised, but its recovery has been low.
