Distribution of South Africa’s Sharks & Rays Maps
Each of these maps show the distribution of a different shark or ray species that occurs in South African waters. The distribution has been modelled using data from many collaborators across the country and internationally, as well as from public data repositories. Each distribution is restricted to South Africa’s Exclusive Economic Zone (EEZ) which goes out for 200nm (~370km) from the coastline.
The resolution of these distribution maps is 10 x 10 km. This means that the EEZ has been divided into 10km 2 grid cells and each grid cell has been assigned a value between 0 and 1 which represents a scale of the probability of occurrence for the given species in that specific grid cell. A value of 0 (purple) indicates a very unlikely probability of the species occurring in that area whilst a probability of 1 (yellow) indicates a very strong probability of the species occurring in the area.
Overlaid on top of each map is an outline of the IUCN (International Union for Conservation of Nature) range for that species (when available).
These modelling methods are described in the WILDOCEANS Conservation Plan Report (under Reports Tab)
