Crown Of Thorns Eradication 


AMPTO is proud to be involved with the Crown of Thorns Program (COTS) 

The increased use of nutrients, pesticides and other pollutants on the land results in more of these entering waterways and the Great Barrier Reef. Current scientific evidence indicates that elevated nutrient levels are linked to outbreaks of crown-of-thorns starfish. The elevated nutrient levels cause an increase in phytoplankton, which is the main food source for crown-of-thorns starfish larvae. This enables a much higher than usual number of larvae to survive and develop into juvenile crown-of-thorns starfish at which stage they start feeding on coral.

For local outbreak control in valuable sites seen by visitors to the Great Barrier Reef, The Association of Marine Park Tourism Operators Pty Ltd (AMPTO) is now supplying the latest COTS applicator kits within Australia and Internationally.
