June 2019 – Stony Coral Tissue Loss Disease (SCTLD) was first seen by Blue Ventures staff on June 21, 2019 in the Bacalar Chico Marine Reserve and has still only been reported in this area of northern Belize. The affected species are pillar coral (Dendrogyra cylindrus), brain corals (Colpophyllia natans, Pseudodiploria strigosa), star corals (Montastraea cavernosa, Dichocoenia stokesii and Orbicella annularis) and maze coral (Meandrina meandrites).

Experimental treatments using concrete or chlorine in shea butter beneath an adhesive paste of modeling clay at lesion margins of pillar corals were not successful at stopping the spread of the disease on infected corals.

The Belize Coral Reef Monitoring Network is developing the country’s official response and an action plan.
July 10, 2019 – The Government of Belize Fisheries Department Press Release
The Fisheries Department has confirmed the presence of the Stony Coral Tissue Loss Disease (SCTLD) on the Northern region of the Belize Barrier Reef Complex. SCTLD is a fairly new disease that affects coral reef systems attacking the coral colonies and resulting in loss of live tissue. Infected corals display “blotchy” lesions and high mortality rates. The disease was first reported in Florida in 2014 and more recently in Quintana Roo, Mexico. In June 2019 it was detected and subsequently confirmed in July 2019 at the Bacalar Chico Marine Reserve.
