GREATER ST LUCIA WETLAND PARK, KWAZULU-NATAL,
SOUTH AFRICA
Brief description: There are few comparable protected coastlines
within the tropics as pristine as St Lucia's. The Park is one of the outstanding
natural wetland sites of Africa. It lies on a tropical-subtropical interface
with a wide range of terrestrial, wetland, 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 savannahs. The interaction
of these environments with major floods and coastal storms in the Park's
transitional location have resulted in exceptional species diversity and
ongoing speciation.

ALTITUDE Below sea level to 172m in the Ntambama
and ~170m Maphelane dunes.
PHYSICAL FEATURES The 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 one of the major estuarine systems of Africa. These are separated from
the sea by high forested barrier dunes of wind-blown sand. To its north-west
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 (Watkeys et al.,1993). The soils 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 are unique
for the height, variety and extent of their forest cover. Along the intertidal
and infratidal coast, the coastline has long sandy beaches between reefs
of beach rock. The dunes were formed over the past 25,000 years, and consist
of superimposed sedimentary strata of different ages (Davies Lynn & Partners
1992). They range between 50 and 170 meters high, the highest mapped being
the Ntambama dune (172m). They contain good deposits of ore.
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 36,826ha. The lake, though varying with flood levels, is
13 x 35km long and is connected with the sea through a 15km channel. The
depth of the water averages less than a meter and is predominantly saline.
It 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.
The lake is supplied by five rivers, most of their catchments lying outside
the boundaries of the 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 Mfolozi, have little of their alluvial lower reaches
in the 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 4km wide continental shelf is protected by reserves further
north and, being warmed by the silt-free Agulhas current, has the southernmost
coral reefs on the east African coast - almost the only reefs in South
Africa. These parallel the coast for 155km south from the Mozambique border
at 8 to 35m 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 (Ramsey,1991).
CLIMATE The area lies 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 Park is temporally
and spatially highly variable. At the coast it varies from 1200 to 1300
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 The 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 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; the lake with its uniquely
variable salinity regime;, underwater macrophyte beds, saline reed swamps,
saltmarshes and mangroves; rocky and sandy shores, coral reefs and submarine
canyons.
The Park is at the southernmost end of the Maputaland Centre of Endemism
(van Wyk, 1993) 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 (1983). The flora
is diverse, having 152 families, 734 genera and 2173 species. Within the
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 (Scott-Shaw, 1994). 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 Park.
In the Maputaland Centre at least 168 species and subspecies are considered
endemic or near-endemic (van Wyk,1993). Of these, 44 (27%) are found in
the 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 park and confined to the Eastern Shores area. Kalanchoe luciae
lucia, described recently, is also endemic to the 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
7000ha in the 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,
characterised 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 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 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
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 (Eugenia, Brachylaena, Euclea, Diosporos and
Mimusops species).
Forest types include swamp forest, rare in South Africa, covering 3,095ha
(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
30m 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 30m
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 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 The outstanding 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 Park including the
internationally threatened black rhinoceros Diceros bicornis minor
(13 in the Eastern Shores and 95 in the adjoining Mkusi Game Reserve),
and 150 white rhinoceros Ceratotherium simum. The 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
The 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 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 Park waters. Winter migrations of humpback whale Megoptera
novaangliae and southern right whale Eubalaena australis can
be seen.
Terrestrial invertebrates in the 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 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. The Park is the main South African breeding ground for loggerhead
Caretta caretta, and leatherback turtles Dermochelys coriacea,
with estimated populations of 2500 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 2m long is one of the largest in Africa,
The 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 park include 129
species and are particularly important for their conservation and scientific
value. Within the Park 43 scleractinian (hard coral) and 10 alcyonacean
(soft coral) genera, 14 sponges, 4 tunicates, 812 species of marine
and estuarine molluscs (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 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 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
Park encloses the largest estuarine prawn nursery area in South Africa.
The very diverse avifauna numbers 521 species which is 60% of the South
African total, approximately 200 of which are water birds for which the
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 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 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 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 in the Park (Avery 1980). People of Middle and Late Stone
Age cultures may have inhabited the Maputaland area probably for as long
as 110,000 years (Beaumont et al.1978). The Maputaland plain which includes
the area of the Park was widely settled by agriculturists in the early
and late Iron Ages (250-1840 AD), (Maggs,1984). Shell middens on the coast
testify to extensive use of black mussels (Perna perna) for food
(Hall & Vogel 1980, Maggs et al.1992). These early agriculturists
probably occupied coastal sites 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 park were uninhabited (Bruton et al. 1980). 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 favourable habitat
for grazing species (Taylor,1980).
The name St.Lucia was first applied by Portugese navigators in 1576 (Mountain,1990).
Little is known about the nature of human settlements 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 (Bryant, 1929; Dominy,1992). Both subsequently came
under Zulu domination (Wright & Hamilton,1989). 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 (Ellis,1975) and are now
part of the Park. There was a little settlement along the coast and in
1956 the State Department of Forestry planted 5000ha 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 Park 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 Park, but are not part of it. Nearly 500 local
people enter the Park for the limited use of natural products and there
is a two-week grass and reed gathering period in June by some 1500 people
a day. A progressive neighbour-relations policy fosters good relations
with communities who live near the 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 Approximately
one million visitors enter the Park each year from nine entrance points.
The 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 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 centre at St.Lucia is the
interpretive centre 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 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 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 programmes benefit from research and monitoring.
The research and monitoring records of the environment, biota, and 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 The natural systems protected
within the Greater St Lucia Wetland 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 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
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 Park to the south (1986),
Lake Sibayi and the Lake Kosi System (1991). These total 213,732ha of
which 174,232ha are within the Park and comprise 73% of its area.
The coasts of the 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 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.
The 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 Management of the 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
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 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 Richards Bay-Maputo corridor area (the Lubombo
Spatial Development Initiative) to protect catchments and promote further
agriculture and tourism in the area. There are threats from infestation
by alien plants and to the hydrology of the wetland systems. To counter
them three programmes 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 programme), 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 WWF South Africa, has set up a comprehensive
community conservation programme for the whole of the Greater St Lucia
Wetland Park to develop a sustainable relationship within the protected
area 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, Western
Shores, Lake and islands, Eastern Shores, Tewate Wilderness Area, Sodwana
Bay and the Maputaland Marine Reserve.
MANAGEMENT CONSTRAINTS The most serious threat
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 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 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.
A proposal to dredge-mine heavy mineral ores in the dune forest, was opposed
by conservationists, led to an environmental impact assessment 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 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. 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.
STAFF There is a total of 674 permanent staff
and part-time employees, located at seven administrative centres, three
management outposts and two research stations. Staff implement wildlife
management programs, manage visitor facilities, environmental awareness
programs and conduct research and monitoring projects. The responsibility
for administering the Park lies with the Chief Conservator.
