5.3 Protected-area management policy framework and guiding principles
5.3.1 Community participation
Zandvlei Estuary Nature Reserve will strive to facilitate productive and mutually beneficial partnerships, which will result in appropriate and sustainable recreational and educational activities. This will be achieved through engaging with the various users, line functions, residents and interested parties that utilise the estuary and environs.
The reserve will conduct an environmental education programme in order to raise local environmental awareness and encourage participation in conservation initiatives. This will be done through an environmental education plan that will aim to achieve the following:
- To inspire visitors and communities to consider the environment as an interrelated and interdependent system, of which they are an integral part
- To educate students, educators and community focus groups, and support such groups with resources and information materials
- To develop and implement environmental education programmes suited to the needs of various focus groups
- To develop and implement an interpretation plan that complements the environmental education plan
The programme will be based at the Zandvlei Environmental Education Centre, and will use the greater Zandvlei area. The programme will make use of permanent staff, volunteers and community members in order to present its programmes.
In order to develop and maintain good reserve/community/stakeholder relations, the Zandvlei Action Committee meets quarterly to deal with operational issues. This committee comprises all relevant stakeholders from Council, civil society and recreational groups.
Formal recreational organisations presently lease land adjacent to the reserve, where two facilities for yachting, rowing, wind surfing and sea cadets have been erected.
5.3.2 Safety and security
A safety and security audit aimed at completing a rapid and verifiable analysis of the current security situation, risk zones, security services, infrastructure, staffing and social context has been carried out on Zandvlei Estuary Nature Reserve. See appendix 10 for an executive summary of this report.
5.3.3 Culture-historical, archaeological and paleontological management
Our present understanding is that, although the Muizenberg area is rich in culture-historical assets, nothing of significance is to be found within the boundaries of Zandvlei Estuary Nature Reserve. However, the City of Cape Town’s Cultural Resources Department should review the area, and a culture-historical, archaeological and paleontological zoning should be developed.
5.3.4 Tourism development and management
The Muizenberg area has a variety of economic tourism activities that are currently pursued. A number of these, such as the western-shore picnic area, braai area and caravan park, are located immediately adjacent to the reserve. A fully integrated precinct plan should be developed for Zandvlei Estuary Nature Reserve, which would indicate suitable tourism and recreational development nodes, and will be guided by the infrastructure and zoning plans.
5.3.5 Infrastructure management
The reserve presently has limited infrastructure, with offices, a works building, bridges and three bird hides. However, there are sizable structures, such as roads, bridges, railway lines and bulk services, immediately adjacent to the reserve. Various departments within the City of Cape Town and National Government share responsibility for these structures.
A five-year maintenance plan should be drawn up, and derelict infrastructure with no use should be demolished and the sites rehabilitated.
5.3.6 Biodiversity conservation management
188.8.131.52 Community-based natural resource management
Zandvlei Estuary Nature Reserve presently provides a range of goods and services, varying from direct consumptive use to non-consumptive, passive use. The presence of the water body and estuary positively affects the aesthetic, recreational and therefore also the commercial value of the surrounding area.
Direct-use values: These values comprise the use of the natural resources of the estuary for commercial or subsistence purposes. These can be consumptive uses – for example, the use of fish as food – or non-consumptive, such as the use of the estuary for recreation.
Consumptive uses: Fishing is the primary form of consumptive use, with an unknown quantity of fish being removed from Zandvlei annually. These are primarily alien fish, such as Cyprinus carpio (carp),as well as indigenous estuarine species, such as Liza and Mugil species (harders) and Lichia amia (leervis). Fishing activities are regulated through the issuance of provincial and national fishing permits. Awareness raising campaigns are needed to educate the general public on the permit requirements, the bag and size limits applicable and the identification of fish species.
Callianassa krausii (Sand prawn) is often illegally harvested by means of pumping on the submerged sand flats at the estuary mouth.
From available knowledge, a limited amount of plant material is illegally harvested. This is primarily for the cut flower and gardening trade.
Non-consumptive uses: The wide variety of recreational activities that take place on the vlei would fall into this category. These include wind surfing, yachting, rowing, canoeing and kite surfing. Adjacent recreational activities, such as picnics, braais, walking and camping, are all as a result of the presence of the vlei.
Recreational fishing on a catch-and-release basis, a common pastime at Zandvlei, would also fall into this category.
184.108.40.206 Fire management
Fire plays an essential ecological role in the lifecycle of fynbos species. Fire is crucial to the long-term conservation of species in Zandvlei Estuary Nature Reserve, and is therefore considered an important component of nature reserve management. Fire management involves varying the season, frequency and intensity of fires, and reconciling ecological and practical requirements. Too frequent fires, or fires that burn out of phase with the natural burning regime, present a threat to slower-growing species, which may be eliminated entirely. If fire is excluded from the area, encroachment may result in species losses. Conversely, if vegetation is allowed to burn too frequently, the area becomes degraded, and alien species, especially grasses, could invade. Grasses maintain a shorter fire cycle, and permanently change the vegetation structure and biodiversity value of the area.
The fire management programme for Zandvlei Estuary Nature Reserve involves the monitoring of large wildfires as well as smaller fires,whether natural or unnatural (see appendix 11 for fire management plan). Historic records of fire events in the reserve area as well as post-fire monitoring records assist in the documentation of veld ages, which, in turn, influence fire management. Minimal interference takes place when naturally ignited fires occur. In cases where human-induced fires occur that would simulate a natural fire, the same management responses would apply. Natural fires are limited in spread within the constraints of ecological, project and public safety requirements. All possible actions are taken to prevent the spread of fire onto the adjacent properties. All unnatural fires that threaten the reserve ecologically, or pose a threat to infrastructure and/or public safety, are controlled (Sheasby 2009).
Prescribed burning of vegetation is a management option in areas where vegetation becomes senescent (old) and there is a risk of species loss. The use of prescribed burning practices would assist in maintaining a vegetation mosaic that promotes plant and animal diversity. Accurate fire records and post-fire monitoring data will facilitate the initiation of prescribed burns in the core area of the reserve. The decision to administer prescribed burns is considered on an annual basis and, if required, planned and implemented accordingly including newspaper articles and letter drops of neighbouring properties to increase awareness. Fire may be used to keep fuel loads low, so as to reduce the risk of uncontrolled fires, particularly on the urban edge and in areas that pose a potential risk to infrastructure and public safety. Firebreaks and other fire control measures required by law will be implemented where necessary and feasible (Sheasby 2009).
The nature of the area’s terrain, property boundaries and extensive areas of natural veld increase the chances of fire spreading both into and out of the reserve. Reasonable pre-fire protection measures are necessary, as well as a plan of action in the event of wildfire. The interaction with various City of Cape Town departments and independent stakeholders, and continuous public and private landowner involvement are essential. The development of fire protection and response plans is an important component of the reserve’s fire management.
Fire management implementation in Zandvlei Estuary Nature Reserve involves the following:
- Application of guidelines on seasonal burning intervals and species requirements acquired from relevant documentation and biophysical specialists
- Accurate record keeping of all fires, including details and maps
- Use of fire data and geographic information systems for recording and mapping
- Application of post-fire monitoring programmes
- Application of fire data to determine prescribed burning needs
- Development and implementation of a fire protection and response plan, including affected stakeholders, such as additional City of Cape Town departments and private landowners neighbouring the reserve
220.127.116.11 Soil erosion and control
Due to the flat topography of Zandvlei, there is very limited soil movement. However, upper portions of the catchment, in particular the Keysers river, are on the slopes of Constantia mountain. This steep terrain, coupled with the agricultural activities and urbanised hardening of the catchment, results in sediment being carried by these rivers. The rate of sedimentation in Zandvlei is presently unknown, and requires investigation in terms of its long-term impacts.
Natural erosion events from flooding, wave action or the natural depositing of banks are monitored annually but are not treated unless they pose a risk to adjacent residential property.
18.104.22.168 Invasive-species management
The management of invasive species is a priority within ZandvleiEstuary Nature Reserve. Alien biota need to be controlled and, where possible, eliminated in order to facilitate the re-establishment of natural biodiversity and processes in invaded areas.
Invasive species are plants and animals occurring outside their natural distribution ranges, establishing themselves, spreading, and outcompeting and replacing indigenous species. Alien species are species introduced to areas outside their natural distribution range – alien to a country or region.
Invasive alien species are introduced species, alien to the country/region,which establish, spread, and outcompete/replace indigenous species.
Invasive and alien-species management within the reserve is applied in accordance with the City of Cape Town’s invasive alien species strategy and in coordination with various government-funded initiatives, including Working for Water and Working for Wetlands. Invasive alien plant species could spread rapidly should management fail to continue to implement a properly planned and coordinated programme.
Until recently, invasive species management had focused mainly on woody alien plant species, such as Acacia saligna and Acacia cyclops. Herbacious weeds had been largely ignored. Recent monitoring and the development of an extensive herbaceous weed and grass species survey for the reserve have however shown that some herbaceous species already pose a risk to biodiversity in the area, while others could become one.
In order to protect indigenous species from invasive aliens, the following is required:
- Prioritisation of areas for alien removal, focusing on biodiversity restoration
- The implementation of removal programmes for priority species and areas
- The development and implementation of an invasive and alien management plan as well as a management plan for alien biota
Note: Section 76 of the National Environmental Management Biodiversity Act refers to the need for an invasive-species control and eradication strategy:
In terms of section 76 of the National Environmental Management Biodiversity Act –
(1) The management authority of a protected area preparing a management plan for the area in terms of the Protected Areas Act must incorporate into the management plan an invasive species control and eradication strategy.
The definition of ‘invasive species’ should be noted. An invasive species is any species that establishes and spreads outside its natural distribution range:
(4) An invasive species monitoring, control and eradication plan must include-
(a) a detailed list and description of any listed invasive species occurring on the relevant land;
(b) a description of the parts of that land that are infested with such listed invasive species;
(c) an assessment of the extent of such infestation;
(d) a status report on the efficacy of previous control and eradication measures;
(e) the current measures to monitor, control and eradicate such invasive species; and
(f) measurable indicators of progress and success, and indicators of when the control plan is to be completed.
Invasive and alien faunal species are also controlled in the reserve. Formal plans outlining the monitoring of removal of identified species are however required.
Catchment management and invasive species management need to work in partnership in the riverine and wetland areas. Of concern is the eutrophication of the waterways due to urban stormwater runoff and nutrient loading from agricultural areas. This is causing increased siltation leading to shallow wetlands and expansion of reedbeds.
22.214.171.124 Species introductions
Species that were historically indigenous to the Zandvlei area, and for which suitable habitat and eco-niches are available,may be re-introduced. Several fauna species that previously occurred in Zandvlei are no longer present or down to small numbers.
Prior to the re-introduction of any species, a full proposal is required. Investigation into the availability of suitable habitat for the species with reference to public utilisation of areas is required, as is an investigation into the historical occurrence and status of the species. The effect of re-introducing species to the area must also be researched. Re-introduction of potentially dangerous and problematic species may also require a public participation process. An investigation of suitable sources is also necessary.
All proposed re-introductions need to be recommended and approved by the flora and fauna management committees as well as provincial authorities before implementation. The implementation of any re-introduction programmes must be specified in a plan of action, and documented accurately.
126.96.36.199 Strategic research
The collection of baseline data is essential for determining the presence of species, and to determine the extent to which management actions should take place. Monitoring is required to determine the success of management actions as well as to provide an indication of long-term change. Research on the property is vital for obtaining more knowledge on the environment.
CapeNature has numerous manuals on monitoring and baseline data collection, for further reference and guidance.
5.4 Sensitivity analysis of Zandvlei Estuary Nature Reserve
Zandvlei Estuary Nature Reserve is a considerable asset to the City of Cape Town and significantly contributes to national vegetation targets of threatened vegetation types, as listed in the National Spatial Biodiversity Assessment (Driver et al. 2005), as well as providing a service and facilities to local residents and schools.
The development of the sensitivity and zoning plan is one of the steps required in compiling a CDF for Zandvlei Estuary Nature Reserve. CDFs are tools to reconcile the various landuse needs, and to delineate visitor user zones and the positioning and nature of new infrastructure, access points, roads and facilities.
The CDF process has grown in response to the requirements of the National Environmental Management Biodiversity Act of 2004, and seeks to comply with the spatial planning requirements of the Act. The CDFs will ensure that best practice and sustainable development principles are integrated with spatial planning in protected areas.
The sensitivity-value analysis is the landscape analysis portion of the broader CDF. It is a multi-criteria decision-support tool for spatial planning, designed to present the best available information in a format that enables defensible and transparent decision making. The sensitivity-value process is based on the principle that the acceptability of a development (or placement of a structure) at a site is based on that site’s value (arising from the site’s biodiversity, heritage, aesthetic or other values) and its sensitivity or vulnerability to a variety of disturbances (Holness 2005).
The sensitivity-value analysis, the CDF and the associated zoning plan should form part of an adaptive management system, and will grow and change over time as the understanding of the landscapes and ecosystems improves. However, they will never replace the need for detailed site and precinct planning and EIA compliance at site level.
The methodology used for both the sensitivity-value analysis and the zoning process was adapted from Holness and Skowno (2008) and SRK Consulting (20081; 20082). All geographic information work was carried out in ESRI’s ArcMap, version 9.3.1, using the ArcInfo licence level, with Spatial Analyst and 3D Analyst extensions. See appendix 12 for the complete sensitivity-value analysis and zoning process (Purves 2010).
5.5 Zoning plan of Zandvlei Estuary Nature Reserve
5.5.1 Zoning informants
This section briefly outlines the values underlying the identification of broad tourism use zones. It is important to remember that the landscape/biodiversity analysis is just one of the informants in the zoning process. Although the biodiversity analysis is intrinsically a relatively objective scientific process, other informants to the zoning process are not.
Although every attempt is made to place high sensitivity-value sites into more protected zones where possible, the zoning process is essentially a compromise between environment and development. In particular, the identified high-value sites are often the key biodiversity assets that need to be made available to the eco-tourism market in an appropriate manner. The biodiversity layers and the spatial management of the reserve are directly linked during the identification of special management areas. Even within broad high-tourist use zones, some areas are likely to be subject to very tight conservation controls (potentially including complete exclusion of human impacts from an area).
Underlying decision-making rules used in the zoning process
- The zoning process is aimed at striking a balance between environmental protection and the development required to meet the broader economic and social objectives of the reserve.
- The zoning process takes into account existing development footprints and tourism access routes.
- This is based on the underlying principle that, all else being equal, an existing transformed site is preferable to a green-field site, from a biodiversity perspective.
- Infrastructure costs are dramatically increased when developments take place away from existing infrastructure.
- Existing tourism nodes and access routes are a reality of the economic landscape, and it would not be possible to shut down existing tourism sites that compromise the development objectives of the reserve.
- Where existing development nodes, tourist sites and access routes occur in areas with high sensitivity-value, the broad-use zoning aims to keep the development footprint as small as is realistically possible, preferably within the existing transformed site.
- Where possible, sites with high biodiversity sensitivity-value are put into stronger protection zones.
- Peripheral development is favoured and should, where possible, be located outside the conservation area.
- The designation of a broad-use zone does not imply that all sites within that zone would be suitable for all the development types anticipated. Detailed site-level planning is still required, and many sites may prove to be unsuitable at a site/precinct/EIA level of planning.
- Special management areas/overlays need to be formalised and linked to the management plans.
5.5.2 Zoning definitions and descriptions
The zoning definitions and descriptions were workshopped with area and regional managers. Four categories were decided on, namely primary conservation zone, conservation zone, low-intensity leisure zone and high-intensity leisure zone. Appendix 12 outlines the proposed zoning and zone descriptions within the Sensitivity and value analysis report. Map 6 outlines the zoning for Zandvlei Estuary Nature Reserve. The process is still linked to the zoning used for the CapeNature reserves (Holness& Skowno 2008), as there should be general alignment of the broader use zones to enable comparison and integration if provincial documents so require.
6. DEVELOPMENT PLAN
The development plan is still to be completed within the detailed precinct planning for the high-intensity use zone. This plan will indicate suitable development nodes, and will be guided by the infrastructure and zoning management plans.
