Addo Elephant National Park Marine Protected Area


The Addo Elephant National Park Marine Protected Area is a marine conservation area in Nelson Mandela Bay, Port Elizabeth.

History

The MPA was proclaimed by the Minister of Environmental Affairs, in terms section 43 of the Marine Living Resources Act, 18 of 1998.
MPA established date: 2005
Mix of restricted and controlled zones. Consultation with commercial fishermen, divers and other members of the public.
Approved by Cabinet on Wednesday, 24 October 2018, and proclaimed on 23 May 2019.

Purpose

A marine protected area is defined by the IUCN as "A clearly defined geographical space, recognised, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values".
The Addo MPA is focused on protecting economically important linefish like kob and white steenbras.

Extent

The MPA extends 80 km eastward from Coega harbour, with an area of 1200 km2, and includes the estuary of the Sundays river from S33°37.665’, E025°44.082’ to the mouth of the river. The MPA includes the seabed and the water above it.

Boundaries

The boundaries of the MPA are:
The MPA has a mix of restricted and controlled zones. Commercial fishermen, divers and other members of the public were consulted during the planning phase.

Restricted zones

Bird Island inshore and offshore restricted zone:
St. Croix Island offshore restricted zone:

The marine protected areas of South Africa are the responsibility of the national government, which has management agreements with a variety of MPA management authorities, in this case, South African National Parks, which manages the MPA with funding from the SA Government through the Department of Environmental Affairs.
The Department of Agriculture, Forestry and Fisheries is responsible for issuing permits, quotas and law enforcement.

Use

A permit must be issued by the management authority for the following activities:

Scuba diving

Scuba diving in the MPA is only allowed in the Marine Protected Area in the St Croix offshore restricted zone, the Cannon Rock inshore and offshore controlled zone and the Sundays inshore and offshore controlled zone. The diver must be in possession of a personal permit to dive in marine protected areas. Operating a scuba diving business in these zones requires the operator to have a permit for that purpose.

Ecology

Rocky shores, sandy shores, offshore reef, soft marine sediments and estuaries are all represented in the MPA.
The MPA is in the warm temperate Agulhas inshore marine ecoregion to the east of Cape Point which extends eastwards to the Mbashe River. There are a large proportion of species endemic to South Africa along this coastline.
Three major habitats exist in the sea in this region, distinguished by the nature of the substrate. The substrate, or base material, is important in that it provides a base to which an organism can anchor itself, which is vitally important for those organisms which need to stay in one particular kind of place. Rocky shores and reefs provide a firm fixed substrate for the attachment of plants and animals. Sandy beaches and sediment bottoms are a relatively unstable substrate and cannot anchor many of the benthic organisms. Finally there is open water, above the substrate and clear of the sessile biota, where the organisms must drift or swim. Mixed habitats are also frequently found, which are a combination of those mentioned above.
Rocky shores and reefs
There are rocky reefs and mixed rocky and sandy bottoms. For many marine organisms the substrate is another type of marine organism, and it is common for several layers to co-exist. Examples of this are red bait pods, which are usually encrusted with sponges, ascidians, bryozoans, anemones, and gastropods, and abalone, which are usually covered by similar seaweeds to those found on the surrounding rocks, usually with a variety of other organisms living on the seaweeds.
The type of rock of the reef is of some importance, as it influences the range of possibilities for the local topography, which in turn influences the range of habitats provided, and therefore the diversity of inhabitants. Sandstone and other sedimentary rocks erode and weather very differently, and depending on the direction of dip and strike, and steepness of the dip, may produce reefs which are relatively flat to very high profile and full of small crevices. These features may be at varying angles to the shoreline and wave fronts. There are fewer large holes, tunnels and crevices in sandstone reefs, but often many deep but low near-horizontal crevices.
Sandy beaches and unconsolidated sedimentary bottoms
Loose sediment bottoms at first glance appear to be fairly barren areas, as they lack the stability to support many of the spectacular reef based species, and the variety of large organisms is relatively low. The sediment is continually being moved around by wave action, to a greater or lesser degree depending on weather conditions and exposure of the area. This means that sessile organisms must be specifically adapted to areas of relatively loose substrate to thrive in them, and the variety of species found on a sandy or gravel bottom will depend on all these factors. Loose sedimentary bottoms have one important compensation for their instability, animals can burrow into the sediment and move up and down within its layers, which can provide feeding opportunities and protection from predation. Other species can dig themselves holes in which to shelter, or may feed by filtering water drawn through the tunnel, or by extending body parts adapted to this function into the water above the sediment.

Endemism

The MPA is in the warm temperate Agulhas inshore marine bioregion to the east of Cape Point which extends eastwards to the Mbashe River. There are a large proportion of species endemic to South Africa along this coastline. Nelson Mandela Bay has the largest proportion of endemic marine invertebrates and seaweeds on the South African coastline.
