This reporting system outlined in this project is the official COTS monitoring and reporting system of the Marine Park<\/strong>, as endorsed by the Raja Ampat Marine Park Authority and local government for the management of COTs in the region. All culling events or sightings are required to be reported via this system. It is only through collaborative evaluation and management that we can begin to collectively address the current challenges associated with Crown of Thorns Starfish outbreaks in Raja Ampat.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”The Crown of Thorns Starfish Section” _builder_version=”4.0.7″ custom_padding=”0px||||false|false”][et_pb_row admin_label=”The Crown of Thorns Starfish Row” _builder_version=”4.0.7″ custom_padding=”||15px||false|false”][et_pb_column type=”4_4″ _builder_version=”4.0.7″][et_pb_text admin_label=”The Crown of Thorns Starfish Text” _builder_version=”4.0.7″ text_font=”Open Sans||||||||” text_text_color=”#666666″ text_font_size=”16px” text_line_height=”1.8em” header_2_font=”Lora|700|||||||” header_2_text_color=”#333333″ header_2_font_size=”50px”] The crown-of-thorns starfish (Acanthaster plana) is a species native to coral reefs in the Indo-Pacific region. One of the largest starfish in the world, it grows up to 1m in diameter, and derives its name from its venomous thorn-like spines covering its upper surface. Crown of Thorns Starfish (COTs) are widely distributed across the Indo-Pacific. COTs feed on hard corals, by releasing the contents of their stomach onto the coral, and using digestive juices to dissolve the coral for consumption, leaving behind only the white skeleton. With few natural predators (including triton trumpet, pufferfish, porcupine fish and napoleon wrasse), a mature COTs can eat up to 1m2 per week. On healthy coral reefs, where populations exist in balanced numbers, COTs play an important role in reef health; by predating on the fastest growing corals, they free space for the slower growing coral species to form colonies, thus contributing to coral diversity.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_5,3_5″ use_custom_gutter=”on” gutter_width=”2″ _builder_version=”4.0.7″ custom_padding=”0px||||false|false” hover_enabled=”0″][et_pb_column type=”2_5″ _builder_version=”4.0.7″][et_pb_text admin_label=”The Crown of Thorns Starfish Text” _builder_version=”4.0.7″ text_font=”Open Sans||||||||” text_text_color=”#666666″ text_font_size=”16px” text_line_height=”1.8em” header_2_font=”Lora|700|||||||” header_2_text_color=”#333333″ header_2_font_size=”50px”] Yet in circumstances where COTs densities increase to a point where the coral reef cannot recover fast enough from the predation, this is considered an \u201coutbreak\u201d and poses significant threat to the health and resilience of a coral reef ecosystem. In extreme cases of outbreak, such as the Great Barrier Reef in Australia, large areas of reef have been affected: coral cover on surveyed reefs in the GBR declined 50% between 1985-2012, with COTs responsible for almost half of this decline (Australian Government, Great Barrier Reef Marine Park Authority).<\/p>\n At this point in time, the majority of reefs accessed within Dampier Strait and surrounding Raja Ampat, are healthy and abundant, with few COTs per hectare and coral growth and recovery in balance with any COTs predation. However, there are several known (and likely more unknown) locations where it is now considered that the densities and damage caused by COTs have reached outbreak levels, and these are areas of serious concern. At these sites preliminary observations show that as opposed to other parts of the world, COTs in Raja Ampat do not exclusively focus on fast growing corals, but have a much wider diet, predating on any coral colony available on its path.<\/p>\n In a place like Raja Ampat, where both local livelihoods and a lucrative tourism economy depends exclusively on the health of coral reefs, it is vital to do whatever we can to mitigate further coral loss in the region. Rather than wait for existing outbreaks to potentially spread, or until significant damage occurs, The SEA People works closely with the Marine Park Authority, Conservation International, and other stakeholders and operators, in the ongoing monitoring and mitigation of the COTs outbreaks in the Dampier Strait region.<\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=”3_5″ _builder_version=”4.0.7″][et_pb_image src=”http:\/\/theseapeople.org\/wp-content\/uploads\/2019\/12\/Crown-of-Thorns-Raja-Ampat.png” _builder_version=”4.0.7″][\/et_pb_image][et_pb_image src=”http:\/\/theseapeople.org\/wp-content\/uploads\/2019\/12\/Raja-Ampat-Crown-of-Thorns-eating-coral.png” _builder_version=”4.0.7″][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":" COTS in Raja AmpatThis reporting system outlined in this project is the official COTS monitoring and reporting system of the Marine Park, as endorsed by the Raja Ampat Marine Park Authority and local government for the management of COTs in the region.
