Restoration Projects:

  • Testing quicklime application and efficacy and then removing sea urchins at a large scale to restore kelp forest.
  • The objective of restoration was to establish a new substrate/habitat on a sandy bottom outside a sea urchin barren for kelp establishment, and supporting associated macrofauna and juvening fish.
  • Testing quicklime application and efficacy and then removing sea urchins at a large scale to restore kelp forest.

  • The aim of this study was to investigate whether kelp may recover if the abundance of urchins is reduced in a small-scale pilot study. This could provide value by using the profitable commercial harvest of urchins to restore the valuable ecosystem services of kelp forests.
