This study aimed to address the loss of L. nigrescens by assessing its capacity for restoration. This study reports the design and testing of a transplanting device that allows experimental manipulation of the kelp in its natural habitat.
Site Selection Criteria:
Kelps were collected and replanted at the same site, where kelp was present naturally.
Cause Of Decline:
Lessonia nigrescens is one of the most ecologically and economically important species dominating the lower wave-swept intertidal rocky habitats of the eastern southern Pacific. It is an important ecosystem engineer, providing a refuge from desiccation stress and wave impact, food for grazers and habitat for several invertebrate taxa. However, L. nigrescens appears to have a limited tolerance to abiotic changes. This kelp has been decimated from large expanses of coastline in northern Chile due to inter-annual variability induced by the arrival of subtropical warm waters during the El Niño Southern Oscillation (ENSO). Similarly, the chronic disposal of copper-mine wastes to coastal environments in northern Chile, has resulted in the loss of L. nigrescens.
