Mesoamerican Barrier Reef Health Assessment

TIDE surveys coral reef habitats in Port Honduras Marine Reserve (PHMR) to continually assess the health of the ecosystem by monitoring the effects of nutrient and sediment loading on corals from riverine pollution by monitoring changes in macroalgal cover. Fish biodiversity is also monitored to assess the effectiveness of implementation of fisheries regulations.  Surveys are conducted using the Mesoamerican Barrier Reef Survey (MBRS) protocol with some components of the Atlantic and Gulf RAGRRA annexed to make outputs compatible with data collected in other regions by other organisations in either format. Results are contributed to the Healthy Reefs Initiative Annual Report Card. Each area assessed is given a rating from very good to critical in the Report Card.


TIDE's lionfish research aims to monitor the lionfish invasion in PHMR, determining population dynamics and behaviour in the reserve whilst also instigating effective control methods that can be carried out by the local community. Lionfish (Pterois volitans) are an invasive species that have severely affected native fish populations in the Caribbean. Lionfish are native to the Indo-Pacific oceans and the Red Sea, but have swept through Atlantic and Caribbean waters, from Florida to Brazil, during the past 15 years.
