During the months of April and May 2011, the ERI along with local partners, the Southern Environmental Association (SEA), Toledo Institute for Development and Environment (TIDE), Wild Tracks and Sarteneja Alliance for Conservation and Development (SACD) worked in an effort to complete the validation of the 2010 mapping study on the “Identification of Threatened and Resilient Mangroves in Belize” published by the Water Center for the Humid Tropics of Latin America and the Caribbean (CATHALAC) in collaboration the World Wildlife Fund (WWF).
The mapping was done using remote sensing data in order to assess the extent of mangrove habitats for the period 1980 to 2010 and to gauge any variance in mangrove coverage from 1980-2010. Validation is a standard procedure for maps that are developed using remote sensing imagery, to determine if the level of accuracy is sufficient enough for the map to be used. The primary component of validation was the ground-truthing, which is basically a process that involves the work of field technicians, tasked with going out and gathering data on the actual location, type and extent of mangroves in order to prove or disprove the accuracy of the map. Ground-truthing was conducted for Turneffe and Belize City/Drowned Cayes by ERI, SACD and Wildtracks ground truthed Corozal Bay/Sarteneja, while SEA and TIDE took on the ground truthing work for Placencia and Port Honduras respectively.
