A network <strong>of</strong> amazing biodiversityCape Town is a remarkable city – a sophisticatedurban centre <strong>of</strong> international importance, rightin the middle <strong>of</strong> one <strong>of</strong> the world’s biodiversityhot spots.In June 2004, the Cape Floristic Region (CFR)was declared a Natural World Heritage Site<strong>of</strong> “universal significance to humanity”.<strong>The</strong> CFR includes sections <strong>of</strong> theEastern Cape as well as theWestern Cape.<strong>The</strong> CFR is the smallest andrichest <strong>of</strong> the world’s sixfloral kingdoms, and itsentire area is home to9 000 plant species, <strong>of</strong>which about 80% arefynbos plants. Many <strong>of</strong> theseplants are endemic to South Africa –in other words, they occur nowhereelse on earth. About 1 700 <strong>of</strong> thesespecies are threatened; 900 plantsare endangered or critically endangered,and 29 plant species are already extinct.<strong>The</strong> CFR does not merely surround CapeCluster disa(Disa ferruginea)Town; it is part <strong>of</strong> the city’s urban fabric, withcritically endangered plants found on roadverges, indigenous gardens, pavements, sportsfields and public open spaces. Cape Town, witha third <strong>of</strong> the CFR’s plants, has 319 threatenedand 13 extinct plant species on the IUCN’s RedData List – a list <strong>of</strong> species that are either alreadyextinct or at risk <strong>of</strong> extinction in the near future.However, these remnant habitats aredecreasing as Cape Town grows and developsat a rapid pace. To date, the City <strong>of</strong> CapeTown has set aside 31 areas within themetro boundary to be managed asnature reserves. Together with anumber <strong>of</strong> private, provincial andnational reserves in the region, thesenatural areas contribute towards conservingthis biodiversity heritage for our andfuture generations’ enjoyment.However, for more effective protection, thearea under conservation needs to be doubled.Conservation <strong>of</strong> additional areas is therefore apriority in the City <strong>of</strong> Cape Town’s BiodiversityNetwork.Open spaces and gardens with indigenousvegetation and wetlands are vital for anyurban area.Vegetation removes much <strong>of</strong> the carbon dioxidefrom the air. Carbon dioxide, produced by vehicleemissions, industries and even our own breathing,is one <strong>of</strong> the primary causes <strong>of</strong> climate change.Wetlands help to control flooding, managestormwater run<strong>of</strong>f, and clean river water.<strong>The</strong>se spaces also <strong>of</strong>fer the opportunity forenvironmental education and recreation.<strong>The</strong> city’s outdoors and tourism-based economylargely depends on Cape Town’s biodiversity andnatural habitats.Natural environments and urban open spaces<strong>of</strong>fer valuable recreational areas, where adults andyoung people can relax, destress and play.<strong>The</strong> conservation <strong>of</strong> our unique natural andcultural heritage is crucial to Cape Town.Conservation requires cooperation –we need your help …Residents and community organisations, alongwith national, provincial and local government,play an important role in ensuring that naturalareas are identified, proclaimed and protected.Friends <strong>of</strong> the reserves and other local interestgroups help maintain and fund reserves. <strong>The</strong>yparticipate in alien vegetation hacks, fire control,plant and animal monitoring, talks and walks, andalso encourage others to care for nature.Everyone can help tackle littering and wastedumping. By reducing the waste we produce, andreusing and recycling as far as possible, we canhave cleaner and greener natural areas.Anyone can plant and nurture an indigenousgarden, no matter how small, which will <strong>of</strong>fer ahome to the insects, birds and other animals <strong>of</strong>the CFR.Disa atricapilaAristea lugensTHE VALUE OF BIODIVERSITYWe need to conserve biodiversity – not only for itsown sake and for current and future generations,but because intact natural habitats <strong>of</strong>fer manybenefits to us, including an improved quality <strong>of</strong> lifeand health, through the many ecosystem goodsand services they provide.Well-managed natural areas <strong>of</strong>fer recreationaland educational, as well as sustainable harvestingand nature-based tourism, opportunities, and areknown to enhance adjacent property values. InCape Town, tourism is one <strong>of</strong> the most importantindustries to create jobs.<strong>The</strong> conservation <strong>of</strong> natural and semi-naturalareas has many benefits. Some <strong>of</strong> these include:• reducing the force and effect <strong>of</strong> floods;• filtering run<strong>of</strong>f and air pollution;• replenishing groundwater;• serving as an atmospheric carbon sink;• producing oxygen;• <strong>of</strong>fering tourism, recreational and educationalopportunities and cultural/spiritual spaces;• providing food, raw materials, medicines andgenetic stock for horticultural cultivars;• controlling erosion; and• future use (e.g. new research).In addition, well-managed conservation and publicopen space areas are associated with improvedurban community relationships and reduced levels<strong>of</strong> violent crime in adjacent areas.PAGE 6PAGE 7
