[This is the first in a series of blogs by WCS-Fiji Director Sangeeta Mangubhai assessing the damage to coral reefs caused by Cyclone Winston, a Category 5 storm that hit Fiji on February 20]

Much of our effort so far, has been around providing food and water relief to our communities until authorities and humanitarian organizations can step in. However, over the next 10 days, through the generous support of Nai’a Cruises (a live-aboard ship that has been diving in Fiji since 1993), I have the opportunity to survey coral reefs throughout the Vatu-i-Ra Seascape to assess the damage caused by Cyclone Winston and collect data on coral bleaching.

Why is this important? Fijians are highly reliant on their coral reefs for both food and for livelihoods. Because fish are the main source of protein, healthy productive coral reefs and their associated fisheries are critical to Fiji’s food security.

I will be using two main techniques to assess the reefs. First, I —> Read More
