St. Lucia Wetlands - Introduction
The Greater St. Lucia Wetlands Park (now
the Isimangaliso Wetlands Park) (32°0625E
to 32°5646E. and 26°5126S
to 28°2907S) is a World Heritage Site. There are
few comparable protected coastlines within the tropics as pristine as
St. Lucia's. The St. Lucia Wetlands Park is
one of the outstanding natural wetlands sites of Africa. It lies on a
tropical-subtropical interface with a wide range of terrestrial, wetlands,
estuarine lake, coastal and marine environments, which are scenically
beautiful and basically unmodified by people. These include coral reefs,
long sandy beaches, coastal dunes, lake systems, swamps, and extensive
reed and papyrus wetlands, critical habitat for a range of species from
Africa's sea, wetlands and savannas. The interaction of these environments
with major floods and coastal storms in the St. Lucia Wetlands
Park's transitional location have resulted in exceptional
species diversity and ongoing speciation.
Geographical Location of the St. Lucia Wetlands
The St. Lucia Wetlands Park is on the east coast of South
Africa 150 miles (mi) north of Durban, in northern KwaZulu-Natal Province,
stretching from the Mozambique border south almost 220 kilometers (km),
1 to 24 km wide, with a 155km x 5km parallel marine strip. The St.
Lucia Wetlands lie between 32°0625E to 32°5646E.
and 26°5126S to 28°2907S.

Altitude
Most of the St. Lucia Wetlands lie below sea level to 172
meters (m) in the Ntambama and ~170m Maphelane dunes.
Physical Features of the St. Lucia Wetlands
The St. lucia Wetlands Park comprises two geomorphic units:
coastal plain and continental shelf. The coastal plain is the southernmost
end of the Mozambique coastal plain. It encloses the lagoon-like lakes
of two of the major estuarine systems of Africa, Lake St. Lucia
and the Kosi Bay Lake System. These are separated from the sea by high
forested barrier dunes of wind-blown sand. To its northwest of the St.
Lucia Wetlands are the low Lubombo mountains in the adjacent Mkusi
Game Reserve. The surficial geology within the site is a complex of terrestrial
and marine sediments. The uppermost, the Cretacean St. Lucia
formation, is very rich in marine fossils which are exposed on the west
coasts of False Bay and Lake St. Lucia. Stratified Quaternary
marine deposits related to marine transgression and regression have resulted
in a series of prominent north-south oriented sandy dune ridges. The soils
of the St. Lucia Wetlands area are largely infertile wind-redistributed
grey and red sands over mudstone and clay pans. Riverbanks are alluvial;
swamps have gley soils.
The coastal dunes along the eastern edge of the coastal plain between
St. Lucia and Kosi Bay are unique for the
height, variety and extent of their forest cover.They are the highest
vegetated dunes in Africa. Along the intertidal and infratidal coast,
the coastline has long sandy beaches between reefs of beach rock. The
dunes east of the St. Lucia Wetlands were formed over the
past 25,000 years, and consist of superimposed sedimentary strata of different
ages. They range between 50 and 170 m high, the highest mapped being the
Ntambama dune (172 m).
Two types of coastal lake systems have formed behind the
coastal dunes: estuarine (Lake St. Lucia and Lake Kosi)
and freshwater (Lake Sibayi, Lake Bhangazi North, Lake Bhangazi South,
Lake Mgobezeleni). The St. Lucia estuarine system covers
36,826 ha. Lake St. Lucia, though varying with flood levels,
is 13km x 35km long and is connected with the sea through a 15 km channel.
The Moth of the St. Lucia Estuary is at the town of St Lucia.
The depth of the water averages less than a meter and is predominantly
saline. Lake St. Lucia has consistently become shallower
during the past century. Only the uppermost section and the mouths of
the feeder rivers are fresh water when inputs are high. Dry season evaporation
is high and causes the inner reaches of the lake to become hypersaline.
The biota adjusts to the fluctuations in salinity. Lake Sibayi is the
largest freshwater lake in South Africa. Lake Kosi is a complex of four
tidal lakes, estuary and swamps.
Lake St. Lucia is supplied by five rivers, most of their
catchments lying outside the boundaries of the St. Lucia Wetlands
Park. North to south these are the Mkuse, Mzizene, Hluhluwe, Nyalazi and
Mpate. The Mfolozi and Msunduze rivers in the south enter the sea together
close to the mouth of Lake St. Lucia. The largest rivers,
the Mkuze and iMfolozi, have little of their alluvial lower reaches in
the Wetlands Park. The rivers are seasonal, flowing during
the wet summer months and reduced to isolated pools and seepage through
bed sediments in winter. High sediment loads from the Mkusi river which
drains the Lubombo mountains have filled its arm of the lake to form meandering
distributaries, levees and pans with swamp and riverine forest.
The narrow, 2 to 4 km wide continental shelf of the coast of St.
Lucia and the Wetland Park, is protected by reserves further north
and, being warmed by the silt-free Agulhas current, has the southernmost
coral reefs on the east coast of africa - almost the only reefs in South
Africa. These parallel the coast for 155 km south from the Mozambique
border at 8 to 35 m deep. Seven submarine canyons formed by palaeo-river
outlets capture the silt brought by the Agulhas current and permit deep
oceanic water and biota associated with it to reach near to the shore.
Climate of the St. Lucia Wetlands
The St. Lucia Wetlands lie between tropical and subtropical
zones with warm, moist summers and mild dry winters. The Agulhas current
warms the coast. The mean annual temperature exceeds 21°C. There is
an east-west climatic gradient with the coast being moist with high precipitation
and the inland area moderately dry. Rainfall in the St. Lucia Wetlands
Park is temporally and spatially highly variable. At the coast it varies
from 1200 to 1300 millimeters (mm) per annum with 60% of the rain falling
in summer (November to March). Evaporation rates are high and there is
occasional large-scale flooding. The prevailing winds parallel the coast.
Vegetation of the St. Lucia Wetlands area
The S.t Lucia Wetlands Park, lying on the interface between
tropical and sub-tropical biota with varied geomorphic and climatic conditions,
supports an exceptional ecological and biological diversity, especially
of wetlands. The distribution of the vegetation within the St. Lucia
Wetlands area is largely determined by topography, moisture regimes
and edaphic conditions. The system is almost pristine and still functions
well. It is a rich mosaic of savanna grassland, thickets and woodlands;
grasslands: low-lying, hygrophilous and floodplain; sedge swamps, freshwater
reed and papyrus swamps; riverine woodlands, swamp forests and forested
dunes; lake St. Lucia, with its uniquely variable salinity
regime;, underwater macrophyte beds, saline reed swamps, salt marshes
and mangroves; rocky and sandy shores, coral reefs and submarine canyons
off the coast of Sodwana Bay.
The St. Lucia Wetlands Park is at the southernmost end
of the Maputaland Centre of Endemism which extends from the Limpopo to
the St. Lucia estuaries, east of the Lubombo mountains.
It is one of two foci of high endemism in the Tongaland-Pondoland Regional
Mosaic of White. The flora of St. Lucia is diverse, having
152 families, 734 genera and 2173 species. Within the St. Lucia
Wetlands Park 98% (2173 species) of the Maputaland Centre species,
approximately 9% of the flora of South Africa and 31% of the flora of
KwaZulu-Natal, have been recorded in the Park. 32 species are listed in
the South Africa Red Data Book for Plants and 8 species are contained
in CITES appendices. 6 species are endemic to KwaZulu-Natal and 3 species
are known only from the Greater St Lucia Wetland Park.
In the Maputaland Centre at least 168 species and subspecies are considered
endemic or near-endemic. Of these, 44 (27%) are found in the, Wetlands
Park. The following species are of phytogeographic interest: Helichrysopsis
septentrionale (Maputaland endemic), four regional endemic genera (Brachychloa,
Ephippiocarpa, Helichrysopsis and Inhambanella), Restio zuluensis, an
endemic, Wolffiella welwitschii, a recently discovered endemic, the smallest
flowering plant in southern Africa and Thalassodendron ciliatum,
the only marine flowering plant found on the south African coastline.
A new small grassland aloe with affinities to Aloe parviflora awaits description.
It is endemic to the St. Lucia Wetlands Park and confined
to the St. Lucia Eastern Shores area. Kalanchoe luciae lucia,
described recently, is also endemic to the St. Lucia Wetlands
Park. 136 species are at their southern limit and there are some notable
disjunct distributions.
The wetlands of this unique estuarine system include freshwater Phragmites
australis - Cyperus papyrus swamp which covers approximately 7,000 ha
in the St. Lucia Wetlands Park, forming the largest protected
wetland in South Africa; saline reed swamp on alluvium and islands in
Lake St. Lucia, dominated by Phragmites mauritianus; sedge
swamp, mainly in the Mfabeni swamp, characterized by Eleocharis limosa;
salt marsh dominated by Sporobolus virginicus, Paspalum vaginatum with
Juncus kraussii (ncema, commercially used by local people), and nutrient-rich
submerged macrophyte beds on saline lake-bed soils.
Grassland types in the St. Lucia Wetlands Park include
hydrophilous grassland on sandy riverine soils dominated by Acroceras
macrum and Ischaemum arcuatum; high-lying grasslands on sand, a diverse
fire-subclimax community, palm-veld with Hyphaene coriacea and Phoenix
reclinata, another fire-subclimax community; Echinochloa floodplain grassland;
and low-lying grasslands on clay.
Open woodlands in The St. Lucia Wetlands Park include mixed
Acacia/broad-leaved woodland (Hyphaene coriacea and Ziziphus mucronata)
and mixed Acacia woodland (Acacia nigrescens, A.gerrardii, A.tortilis,
A.nilotica) which provide grazing and browsing for herbivores. Closed
woodlands are found aound the St. Lucia Wetlands on low-lying
drainage lines and older alluvial soils, especially along the Mkuze and
Msunduzi rivers. They include riverine woodland (Ficus sycomorus, Acacia
xanthophloea); mixed Acacia closed woodland (A.tortilis, A.nilotica);
broad-leaved woodland (Combretum molle, Zizphus mucronata) and Terminalia
sericea -Strychnos woodland and scrub. Thickets of mixed microphyllous
and broad-leaved woodland subject to salt spray and wind occur on seaward-facing
dune slopes between St. Lucia and Kosi Bay.
(Eugenia, Brachylaena, Euclea, Diosporos and Mimusops species).
Forest types in the St. Lucia Wetlands Park include swamp
forest, rare in South Africa, covering 3,095 ha (64% of
the South African total) dominated by Ficus tricopoda, hygrophilous forest
and Barringtonia forest. (B. racemosa). These occur on organic soils in
hypo-saline drainage lines and marshes around freshwater lakes usually
flooded with slow-flowing water after rains; mangroves, dominated by Bruguieria
gymnorrhiza and Avicennia marina; the uniquely well developed coastal
dune forest (Mimusops caffra, Grewia occidentalis, Psychotria capensis)
which can reach 30 m high and has a dense shrub layer with many lianas;
sand forest on relict dunes of highly-leached sands (Newtonia hildebrandtii,
Cleistanthus schlechteri); and coastal lowland forest growing to 30 m
high on highly leached sands (Strychnos decussata, S.gerrardii); also
plantations of Pinus elliottii.
In the marine flora, 325 seaweeds have been recorded in the St.
Lucia Wetlands Park, nearly 78% of the total seaweeds of the Kwazulu-Natal
coastline. A new species, Cellophycus condominius, and a parasitic red
alga, Calocopsis smithenae, have recently been found; also beds of kelp
Ecklonia biruncinata, deep in submarine canyons.
Fauna of the St. Lucia Wetlands
Park.
St Lucia's diversity of habitats, terrestrial, wetland, coastal and aquatic,
supports a wide variety of animal species, some at the northern and many
at the southern limit of their range. The fringing coral reefs are among
the southernmost in the world. The lakes, swamps and shallows comprise
the most productive estuarine prawn nursery and marine nursery on the
South African coast.
There are 97 species of terrestrial mammals in the St. Lucia Wetlands
Park including the internationally threatened black rhinoceros Diceros
bicornis minor (20 in the Eastern Shores and 95 in the adjoining Mkusi
Game Reserve), and 150 white rhinoceros Ceratotherium simum. The St
Lucia Wetlands Park has the largest single populations
in South Africa of hippopotamus Hippopotamus amphibius (about 700), red
duiker Cephalophus natalensis natalensis and southern reedbuck Redunca
arudinum, also the largest publicly protected populations in KwaZulu-Natal
of thicktailed bushbaby Otolemur crassicaudatus, samango monkey Cercopithecus
mitis, sidestriped jackal Canis autoists, banded mongoose Mungus mungo,
brown hyaena, Hyaena brunnea, bushbuck Tragelaphus scriptus, Tonga red
squirrel Paraxerus palliatus tongensis, cane rat Thryonomys swinderianus
and fourtoed elephant shrew Petrodromus tetradactylus also occurs at St.
Lucia.
The St. Lucia Wetlands Park is also the only
protected area in KwaZulu-Natal known to have populations
of two shrew species, the lesser red musk Crocidura hirta and greater
dwarf shrew Suncus lixus; eight species of bat: Eygptian fruit Rousettus
aegyptiacus, Geoffroy's horseshoe, Rhinolophus clivosus, shorteared trident,
Cloeotis percivalli, butterfly Chalinolobus variegatus, Schlieffen's Nycticeius
schleiffeni, lesser woolly Kerivoula lanosa, Ansorge's freetailed, Tadarida
ansorgei, Angola freetailed T.condylura; also sidestriped jackal and two
species of gerbil, bushveld Tatera leucogaster and highveld T.brantsii.
The St. Lucia Wetlands Park also contains
populations of five species endemic to South Africa: Hottentot
golden mole Amblysomus hottentotus, hairy slitfaced bet Nycterus hispida,
Natal red hare Pronolagus crassicaudatus, Tonga red squirrel and red duiker.
All 32 marine mammal species are both internationally threatened and
listed in CITES appendices. Populations of bottlenose Tursiops truncatus,
humpback Sousa plumbea and spinner Stenella longirostris dolphins live
in the waters of the St. Lucia Wetlands Park.
Winter migrations of humpback whale Megoptera novaangliae and southern
right whale Eubalaena australis can be seen coming past St Lucia,
Sodwana Bay and Kosi Bay.
Terrestrial invertebrates in the St. Lucia Wetlands
Park are known to be numerous and diverse, supporting much of
the conspicuous fauna. There are 196 species of butterflies (49% of Kwazulu-Natal
species), 52 species of dragonflies (23% of South African
species), 139 species of dung-beetles, 27 species of hole-nesting wasps,
64 species of biting flies (64% of South African tabanids),
58 species of chafer beetles (cetonids) and 41 species of land snails.
The herpetofauna of the St. Lucia Wetlands is rich: 50
amphibians and 109 reptiles: and one crocodile, 12 species of Chelonidae,
53 snakes and 42 lizards and chameleons, including Bouton's coral rag
skink Cryptoblepharus boutoni africanus, found only here in South
Africa. The Mozambique shovelsnout snake and three
South African endemics: two burrowing skinks, the striped
Stelotes vestigifer and Fitzsimon's S. Fitzsimonsi and Setaro's dwarf
chameleon Bradypodion setaroi, are found only in the coastal dune system
In the St. Lucia Wetlands Park. The St.
Lucia Wetlands Park is the main South African
breeding ground for loggerhead Caretta caretta, and leatherback
turtles Dermochelys coriacea, with estimated populations of 2,500 and
750 females respectively. Non-breeding green turtles Chelonia mydas are
also resident and hawksbill Eretmochelys imbricata and olive ridley Lepidochelys
olivacea turtles visit the coast. The population of Nile crocodiles, Crocodylus
niloticus, of approximately 1500 animals over 2 m long is one of the largest
in Africa, The St. Lucia Wetlands Park contains
populations of 5 amphibians endemic to KwaZulu-Natal, 2
being nationally threatened, and 6 internationally and 20 nationally threatened
reptile species; 16 listed in CITES appendices.
Marine and estuarine invertebrates are far the most important group of
aquatic invertebrates. The coral-inhabited reefs of the St. Lucia
Wetlands Park include 129 species and are particularly important
for their conservation and scientific value. Within the St. Lucia
Wetlands Park, 43 scleractinian (hard coral) and 10 alcyonacean
(soft coral) genera, 14 sponges, 4 tunicates, 812 species of marine and
estuarine mollusks (72% of Kwazulu-Natal coastal species),
including the giant clams Tricdaca maxima and T.squamosa, and 198 species
of Crustacea have been recorded.
The ichthyofauna of the St. Lucia Wetlands Park includes
nearly 85% of the reef fish species endemic to the west Indian Ocean region
(399 species) including several commercially important endemics such as
the slinger Charysoblephous puniceus. 991 species have been recorded.
including summer aggregations of ragged-toothed shark Tiburon odontaspis
and whale shark Rhynchodon typus. The 212 estuarine species occur in the
St. Lucia and Kosi estuaries, include the large Zambezi
shark Carcharhinus leucas. The fresh water fish fauna comprises 55 species
including 6 internationally threatened and 16 nationally threatened species.
The St. Lucia Wetland Park encloses the largest estuarine
prawn nursery area in South Africa.
The very diverse avifauna numbers 521 species in the St. Lucia
area, which is 60% of the South African total, approximately
200 of which are water birds for which the Wetlands Park is an important
refuge. The 339 breeding species include 23 of the 97 migrant species.
There are four species endemic to South Africa and 47 endemic
or nearly endemic to the region. The St. Lucia Wetlands Park
is an important breeding area for the pinkbacked pelican Pelecanus rufescens,
white pelican P. onocrotalus, African fish-eagle Haliaeetus vocifer, Caspian
tern Hydroprogne caspia, goliath heron Ardea goliath, rufous-bellied heron
Butorides rufiventris, yellowbilled stork Mycteria ibis, pygmy goose Nettapus
auritus, collared pratincole Glareola pratincola and greyrumped swallow
Pseudohirondo griseopyga. The St. Lucia Wetlands Park is
also habitat for major South African populations of greater
and lesser flamingo Phoenicoepterus ruber, and P.minor, osprey Pandion
haliaetus, Neergaard's sunbird Nectarinia bifasciata, Woodward's batis
Batis fratrum, Natal nightjar Caprimulgus natalensis, blackrumped button-quail
Turnix hottentotta, black coucal Centropus bengalensis and shorttailed
pipit Anthus brachyurus. 62 species are listed in the South African
Red Data Book and 73 species are listed in CITES appendices.
Cultural Heritage
The first evidence of human occupation of the area now covered by the
St. Lucia Wetlands Park dates from the Early Stone Age.
Three occupation sites of the Acheulian culture (between 500,000 and a
million years B.P.) have been found around St. Lucia and
northward to Sodwana Bay and Kosi Bay.. People of Middle
and Late Stone Age cultures may have inhabited the Maputaland area probably
for as long as 110,000 years. The Maputaland plain which includes the
area of the St. Lucia Wetlands Park was widely settled by
agriculturists in the early and late Iron Ages (250-1840 AD). Shell middens
on the coast testify to extensive use of black mussels (Perna perna) for
food. These early agriculturists probably occupied coastal sites at St.
Lucia, Cape Vidal and Kosi Bay as
early as 1600 years ago, cutting fields in and living in the forest.
Due to the prevalence of malaria and the cattle disease trypanosomiasis,
carried by the tsetse fly Glossina, extensive areas of what is now the
St. Lucia Wetlands Park were uninhabited. Small scattered
settlements of the Sokhulu people were present between Sodwana and
the St. Lucia estuary, evidenced by several traditional burial
sites. These people smelted bog iron, felling trees to produce charcoal
for their smelters. The effects of their agriculture and iron-smelting
may have modified habitats by increasing sub-climax grassland in the place
of forest, creating favorable habitat for grazing species.
The name St. Lucia was first applied by Portugese navigators
in 1576. Little is known about the nature of human settlements around
St. Lucia until the early nineteenth century. Maputaland
was then occupied from the north by two culturally distinct groups: Nguni-speaking
people in the south and Tembe-Thonga people in the north. Both subsequently
came under Zulu domination. A tribal wildlife sanctuary was established
in the mid 19th century within the present adjacent Mkusi Game Reserve
area. Concern about the destruction of wildlife after annexation in 1884
led to demarcation of game sanctuaries in 1895 and later. These are the
oldest extant game reserves in Africa and are now part of
the St. Lucia Wetands Park. There was a little
settlement along the coast and in 1956 the State Department of Forestry
planted 5,000 ha in the Eastern Shores State Forest, mainly of Pinus elliottii
and species of eucalyptus, but these were phased out in 1991 because of
their low economic value.
Local Human Population
Except in the Coastal Forest Reserve the northern part of the St.
Lucia Wetlands Park, the area is not inhabited. Within this, there
are six small private townships (Enkovukeni, Kwa Dapha, Mqobella, Mbila,
Shazibe, and Hlabezimhlophe) with a combined total population of approximately
200 families. There are also the private villages of Makakatana and St.
Lucia Estuary which are enclaves within the St. Lucia Wetlands
Park. Nearly 500 local people enter the St. Lucia Wetlands
Park for the limited use of natural products and there is a two-week
grass and reed gathering period in June by some 1,500 people a day. A
progressive neighbor-relations policy fosters good relations with communities
who live near the St. Lucia Wetlands Park. This ensures
that communities derive direct benefits from the protected area such as
free access and business and employment opportunities.
Visitors and Visitor Facilities within the St. Lucia
Wetlands
Approximately one million visitors enter the St. Lucia Wetlands
Park each year from nine entrance points. The St. Lucia
Wetlands Park can accommodate 5,736 persons per night in chalets
and camping facilities. 2000 beds are also provided privately in St.
Lucia Estuary village and on privately owned game-ranches next
to the Wetlands Park. Visitor access is controlled and managed
by the KwaZulu-Natal Nature Conservation Service or through
concessions. Recreational access is via wilderness trails, guided walks,
vehicle and boat tours and a network of roads for viewing game. Access
to and diving on the coral reefs is controlled through diving concessionaires.
A crocodile breeding center at St. Lucia is the interpretive
center for the region.
Non-consumptive use of the area is encouraged. Activities include game-viewing,
bird-watching, turtle viewing, camping, caravanning, accommodation in
chalets and bush-camps, day-walks and overnight hiking, also religious
activities (mass baptism). To control tourism there are three ecotourism
use-zones: a zone of low intensity use in the wilderness core of the St.
Lucia Wetlands Park where access is by foot except
for staff; a moderate use zone where visitors can view wildlife from vehicles
and from scattered camps and hides; and high intensity use zones where,
at seven development nodes there are roads, interpretative and educational
displays, guided walks, accommodation and other facilities.
Scientific Research and Facilities
There have been five major successful conservation programs in the St.
Lucia Wetlands Park: of the black rhinoceros, the hippopotamus,
sea turtle beaches, crocodile breeding and the re-establishment of locally
extinct species. There are also programs on the control of alien species,
the management of ungulate populations, rehabilitation of clear-felled
forest in the Eastern Shores and controlled fire management. All these
programs benefit from research and monitoring. The research and monitoring
records of the environment, biota, and St. Lucia Wetlands Park
management are extensive. Records are updated annually or more often as
needed. They are in the form of several computerized databases, reports
and publications and a geographical information system. Main facilities
are located at St. Lucia, the Pietermaritzburg head office,
the Oceanographic Research Institute and elsewhere.
Conservation Value of the St. Lucia Wetlands
The natural systems protected within the Greater St. Lucia Wetlands
Park are unique for their biophysical diversity and for the hydrological
and ecological processes of Lake St. Lucia. There are few
comparable pristine protected coastlines within the tropics. And the Wetlands
Park's concentrations on a tropical-subtropical interface of a range of
grassland, swamp, estuarine lake, coastal dune forest and marine environments,
scenically beautiful and substantially unmodified by people, form one
of the most outstanding natural sites in Africa. The St. Lucia Wetlands
Park is not under serious threat and is large and diverse enough
to survive as a natural area. Four sites have been designated under the
Ramsar Convention as wetlands of international importance: the St.
Lucia System, the turtle beaches/coral reefs of Tongaland adjacent
to the St. Lucia Wetlands Park to the south (1986), Lake
Sibayi and the Lake Kosi System (1991). These total 213,732 ha
of which 174,232 ha are within the Wetlands Park and comprise
73% of its area.
The coasts of the St. Lucia Wetlands Park are spectacular
and are known for superlative natural spectacles: the night-time nesting
and later hatching of leatherback and loggerhead turtles, the migrations
of whales, dolphins and whale sharks offshore; aggregations of feeding
flamingos of up to 50,000 birds, and impressive displays of pelicans,
waders and other waterfowl, the basking and nesting sites of the Nile
crocodile and large concentrations of ungulates. The leatherback
and loggerhead turtle nesting beaches, the black rhinoceros thickets
and woodlands, the species-rich dry sand forest and bushland and the very
diverse mosaic of wetlands are all of global importance. The St.
Lucia Wetlands Park also has sites of significance for understanding
the evolutionary history of the earth following the break-up of Gondwanaland.
These are the upper Cretaceous sedimentary rocks on the western shore
of Lake St. Lucia and False Bay, rich in well-preserved
fossils of marine origin, including giant ammonites and inoceramids and
other bivalves. More than a hundred different species of fossils have
been recorded in the St. Lucia area/
The St. Lucia Wetlands Park is located in a different biogeographic
region from other World Heritage sites in southern Africa (Lake Malawi
National Park in Malawi, Mana Pools and Victoria Falls National Parks
in Zimbabwe and Mosi-oa-Tunya National Park in Zambia) and it represents
a quite different range of biodiversity. Lake St. Lucia
with its fluctuating salinity and adapted biota also contrasts with other
coastal lagoons in Africa, the salinity rising to seawater
levels in times of drought where other coastal lagoons have less varied
ranges of salinity.
Conservation Management of the St. Lucia Wetlands
Management of the St. Lucia Wetlands Park at the provincial
level is by the Board of the KwaZulu-Natal Nature Conservation
Service (KNNCS) working with the provincial administration in accordance
with national and provincial legislation. There is potential for future
trans-frontier development with Mozambique and the establishment
of buffer Biosphere Reserves to the west. Existing land uses in the region
of the St. Lucia Wetlands Park consist of formal and informal
agriculture and forestry, nature conservation, mining and ecotourism which
is a significant industry. A strategy to provide a development framework
and policy guidelines for the development of the region in which the Wetlands
Park is sited is being compiled by the KwaZulu-Natal
provincial authorities. The Kwazulu-Natal provincial government, with
the governments of Mozambique and Swaziland, is also undertaking
a multi-stakeholder planning initiative for the Richard Bay-Maputo corridor
area (the Lubombo Spatial Development Initiative) to protect catchments
and promote further agriculture and tourism in the area around the wetland
park. There are threats from infestation by alien plants and to the hydrology
of the wetlands systems around St. Lucia. To counter them
three programs have been started: the removal of exotic tree plantations,
the removal of alien plant infestations from important water-producing
catchment areas (part of a nationally funded program), and the re-establishment
of the natural hydrological regime by the allocation of water for Lake
St. Lucia.
An integrated planning and development process by the state Nature Conservation
Service (KNNCS) involving various sectors and stakeholders is undertaken
to ensure that land-use planning decisions are complementary and environmentally
sustainable. KNNCS with funding from World Wildlife Fund (WWF) South Africa,
has set up a comprehensive community conservation program for the whole
of the Greater St. Lucia Wetlands Park to develop a sustainable
relationship within the protected area aroung St. Lucia
and to integrate conservation with sustainable development programs. The
following management plans have been compiled by KNNCS: Master Plan for
the Greater St. Lucia Wetland Park, St. Lucia Marine Reserve
Management Plan and Mkuzi Game Reserve Management Plan. Management plans
for seven other component areas are also in preparation: for False Bay,

Management Constraints in the St. Lucia Wetlands area
The most serious threat in the St. Lucia Wetlands Park
is from alien invasive plants, although the area currently affected is
limited. Principal threats are caused by Chromolaena odorata, Psidium
guajava, Pereckia acuelata and Melia azedarach. Under the management programs
to eliminate infestations from the Wetlands Park, the Plant
Protection Research Institute has identified and established a range of
biological control agents. Two potential threats could also affect the
integrity of the ecology of the St. Lucia Wetlands Park:
land-use changes related to the closure of the St. Lucia estuary
mouth by sedimentation, and the reduction in the supply of critical resources.
This threat comes from the transformation of the upper portion of the
Mfolozi Swamps by agriculture. The spread of commercial gillnetting in
the lake is no longer controlled and recently poachers have also been
reported to be overexploiting the resources of False Bay. More than twenty
species, including abalone, crayfish and prawns are at risk, especially
in the area south of St. Lucia towards Cape St. Lucia.
A proposal to dredge-mine heavy mineral ores in the dune forest north
of St. Lucia was opposed by conservationists, led to an
environmental impact assessment on the St. Lucia Wetlands Park
area, and then to a decision ratified by the Cabinet in March 1996 to
ban industrial development in the area. It also led to nomination of the
St. Lucia Wetlands Park as a World Heritage site. Another
potential threat is from offshore leakage from oil tankers which may pollute
the marine and estuarine environments although arrangements exist along
the coastline for managing oil spills. This became a reality when the
Jolly Rubino ran aground at Cape St. Lucia in 2002. Fortunately
no oil reached the St. Lucia Estuary or the St. Lucia
Beach. Finally there have been several land claims by impoverished
communities. These areas include the Eastern Shores State Forest, Cape
Vidal State Forest and Sodwana State Forest. No solution has yet
been reached but the matter is before the Land Claims Court.
