A brand new examine discovered that if 10% of South Africa’s mainland Ocean space, it might end in a 30% vary safety of shark species, with some species having as much as 60% of their habitats lined (and guarded) and would solely require South Africa to extend 5.4% of its present Marine Protected areas.
WILDTRUST, a number one conservation organisation in South Africa, along with a number of collaborators has undertaken a ground-breaking examine to deal with the urgent want for enhanced safety of sharks and rays in South Africa.
The examine, titled “A Systematic Conservation Plan Figuring out Vital Areas for Improved Chondrichthyan Safety in South Africa,” aimed to determine key areas inside South Africa’s continental waters which are very important for the conservation of those imperilled species.
The examine discovered that if 10% of South Africa’s mainland Ocean space, generally known as the Unique Financial Zone (EEZ), have been to be designated as Marine Protected Areas (MPAs), it will meet the 30% vary safety conservation goal for the species included within the examine.
Sharks and rays are among the many most endangered species on the planet, primarily attributable to overfishing. Their gradual development, late maturity, and low reproductive charges make them notably vulnerable to threats that end in inhabitants declines.
Recognising this, in addition to the importance of South Africa as a worldwide hotspot for shark and ray range, WILDTRUST (with funding from the Shark Conservation Fund) initiated the South African “Shark and Ray Safety Undertaking” in 2019. One of many main targets of the venture was to determine areas in South Africa’s waters essential for the conservation of threatened and endemic species, as outlined by the IUCN Purple Listing.
As a part of the examine, a complete of 87 distribution maps have been produced, offering important data for the conservation of sharks and rays. These distribution maps have been additionally included into South Africa’s Vital Biodiversity Space map, guaranteeing the illustration of sharks and rays within the identification of necessary biodiversity habitats.
‘To make sure the accuracy of the collected prevalence knowledge, ongoing professional consultations have been performed, mentioned Nina Faure-Beaulieu, lead creator on the paper and Analysis Assistant at WILDTRUST. ‘Since distinguishing between sure species will be difficult, discussions with consultants within the subject have been essential to validate the info. Elements resembling anomalous occasions and species with migratory patterns have been fastidiously thought-about to make sure the reliability of the distribution maps.’
‘Typically a heat present may end up in species going far out of their standard distribution and such occasions must be thought-about an anomaly in order to not skew their distribution map an excessive amount of,’ added Faure-Beaulieu. ‘We additionally targeted our efforts on species that don’t migrate lengthy distances or that aren’t largely offshore pelagic species. These species will not be as suited to spatial safety since they won’t keep in anybody space for a chronic time period.’s is more likely to be discovered, in addition to fastidiously figuring out key areas for conservation while limiting as a lot as doable the affect on conflicting makes use of. Within the context of sharks and rays, this could imply figuring out the place elevated safety from fisheries might happen, particularly for critically endange
As soon as the info was validated, it was used to create distribution maps that predict the areas the place a speciered and weak species, while additionally not overlapping an excessive amount of with main fishing grounds.
Wanting forward, the examine gives a major milestone within the conservation of sharks and rays in South Africa in addition to a stable basis for additional enchancment and motion for shark and ray conservation in South Africa’s waters.
It demonstrates the ability of collaboration, data-driven approaches, and modern conservation planning to deal with the important threats going through these iconic marine species.
