According to the Division of Aquatic Resources and Eyes of the Reef Network, cauliflower coral (Pocillopora meandrina) was once abundant on shallow coral reefs along West Hawai'i, including Kahalu'u Bay. However, a global thermal stress event resulting in very high ocean temperatures struck West Hawai'i in the fall of 2015, and caused catastrophic bleaching and mortality for more than 90% of the regional population of cauliflower coral. To recover from this event, natural reproductive and replenishment activities of corals are critically important. For more than a decade, researchers have observed annual broadcast spawning events for cauliflower corals, and can now accurately predict when they will likely occur based on season, solar, tidal, and lunar cycles. During broadcast spawning events, corals emit reproductive materials ("gametes") into the water column, and these materials are carried by the tides to mix and generate planktonic coral larvae. During this time, physical disturbance of corals and pollutants in the water (e.g. oxybenzone in many sunscreens) must be minimized to help ensure that corals are successful. The Department of Parks & Recreation and the Kahalu’u Bay Education Center appreciates the public’s understanding and respect of this important coral recovery and replenishment process at Kahalu'u Bay. We also apologize for any inconvenience the closure may cause. For more information, please contact the Kahalu’u Bay Education Center at (808) 887-6411.
