CITY OF CAPE TOWN QUARTERLY REPORT – 1 JANUARY TO 31 MARCH 2017 2
1 EXECUTIVE SUMMARY
A blue-green algal bloom in Rietvlei resulted in the closure of the water since 17/03/2017. Income from
visitors at the Rietvlei Water Area during this quarter was therefore the lowest ever recorded. The water was
only opened to the public again on 30/06/2017. The new visitor tariffs for the 2017/18 financial year came
into effect the next day on 1/07/2017. The daily entrance fees and environmental education fees at the
Rietvlei Water Area remained unchanged for the new financial year.
Two Cape grysbok surveys were conducted in Milnerton Racecourse, indicating that the grysbok numbers
are as high as 30 animals there. Other fauna monitoring activities included camera traps at Milnerton
Racecourse, small mammal trap arrays in the Milnerton Lagoon, and an integrated water bird census.
A Protected Area and Management Effectiveness Tracking review was conducted for the Nature Reserve
on 20/06/2017. The Protected Area Advisory Committee (PAAC) had its seventh meeting on 20/04/2017,
which was attended by 24 representatives from 17 organisations.
Alien and invasive plants that were cleared, including Port Jackson (Acacia saligna), Rooikrans (Acacia
cyclops), Manatoka (Myoporum tenuifolium), Smooth prickly pear (Opuntia monocantha), Yucca species,
Lavatera (Malva arborea), Spanish broom (Spartium junceum), Caster-oil plant (Ricinus communis), Spanish
Giant reed (Arundo donax), Pampas grass (Cortaderia selloana), Red River gums (Eucalyptus
camaldulensis), and Water Hyacinth (Eichhornia crassipes).
The Custodians of Rare and Endangered Wildflowers (CREW) visited the Milnerton Racecourse on 26/04/2017
and the Coastal Section on 01/06/2017. CREW invited members of the staff and public to learn about
identifying indigenous plants and monitoring threatened and endangered flora.
The Milnerton Racecourse land swap restoration project started with the removal of compacted laterite
gravel and the transfer of topsoil, mulch, seeds, and bulbs to the receptor site. Plant cuttings were taken
from living plants in the Nature Reserve to propagate for later replanting into the restoration site.
The dust control operation, that was intended to suppress dust emanating from the season pans, was
stopped and all pipes and other materials were removed from the pans by 09/06/2017. Level 4 water
restrictions were approved by the City of Cape Town. Rainfall remained below average for most of this
quarter until June, when the measured rainfall at Rietvlei increased to above the average for that month. A
very large storm hit the Western Cape on 7/06/2017, bringing with it significant rainfall, strong winds, and a
very strong storm surge that pushed into the Milnerton Lagoon from the sea.
A firebreak was constructed at the northern edge of the Coastal Section adjacent to the Dolphin Beach
Hotel to prevent the possible spread of wildfires from the Nature Reserve onto the hotel property. Wildfires
occurred in the Zoarvlei Section on 24/04/2017 and in the Diep River Section on 14/05/2017.
The Nature Reserve facilities benefited 584 people over 24 event days. Environmental Education also
generated 340 person days of benefit over ten event days. Training of permanent and temporary staff
amounted to 24 person days over 11 training event days.
Illegal overnight structures and displaced people were removed from various locations in the Nature
Reserve, including the Coastal Section, Rietvlei Section, Zoarvlei Section and the Milnerton Lagoon. Other
illegal activities included illegal footpaths, dumping of building rubble, littering, and illegal cattle grazing in
the Diep River Section. Two site cleaning teams worked in the Zoarvlei Section to address the littering.

2 HIGHLIGHTS & CHALLENGES
2.1 CHALLENGE: A blue-green algal bloom in the Rietvlei Water Area resulted in its closure since
17/03/2017. It remained closed for public safety reasons throughout this quarter. The water was only re-
opened to the public again on 30/06/2017 after a consistent decline in the algae toxins was observed.
The water was visibly green (sometimes almost opaque) and at certain times there were very toxic blue-
green scum layers that formed on the shoreline. Samples from these scum layers (sample code: RTV21) were
analysed, and the toxin levels were almost as high as 1600 micrograms of microcystin toxin per liter at times.
This exceeded the World Health Organisation’s (WHO) guidelines for recreational water bodies by two
orders of magnitude (see Figure 2 below).
Apart from the scum samples, weekly water samples from the Milnerton Aquatic Club shoreline (sample
code: MAC) and the Rietvlei jetty (sample code: RTV02) were analysed and graphs of the trends in the
various parameters were maintained. The total count of blue-green algae (Cyanophyceae) cells as well as
chlorophyll levels fluctuated throughout this quarter, but remained high. This indicated that blue-green algal
bloom was persistent (see Figures 3 and 4).
The most important parameter, however, was the microcystin toxins that are released from the algae cells.
Results indicated a gradual and consistent decline in these toxins over a period of three months, even
though some fluctuations were observed at times. The fluctuations could have been caused by variations in
the ambient temperature, the amount of light exposure and light penetration into the water, as well as the
effects of wind. Towards the end of the quarter it became clear that, despite there being high levels of
algae in the water, the quality approached the standard of drinking water (1 microgram of microcystin
toxin per liter) (see Figure 4 below). This justified the re-opening of the water to the public.

2.2 HIGHLIGHT: Two Cape grysbok surveys were conducted in the Milnerton Racecourse Section by
contract reserve supervisor, Kyran Wright, on 26 and 28/06/2017 (see Figure 6 below). Kyran used Biodiversity
Management Branch staff in order to determine whether a previous survey that was conducted by the
former contract reserve supervisor, Landi Louw, and a team of public volunteers, was accurate.
Some fauna specialists were of the opinion that Landi Louw’s survey over-estimated the amount of grysbok,
due to the inexperience of the public volunteers. The results from Kyran’s survey however indicated that the
grysbok numbers were indeed very high with perhaps even more animals than what Landi’s team counted.
Figure 6. Biodiversity Management Branch staff conducted a drive-count census of Cape grysbok in the Milnerton Racecourse Section.

4.1 Alien and invasive vegetation was cleared in several of the Nature Reserve sections.
4.1.1 Hester Pentz, intern reserve supervisor at the Coastal Section, removed various alien species
including Port Jackson (Acacia saligna), Rooikrans (Acacia cyclops), Manatoka (Myoporum tenuifolium),
Smooth prickly pear (Opuntia monocantha), Yucca species, and Lavatera (Malva arborea) using a
combination of manual removal and chemical control methods (see Figures 7 – 10).

4.1.2 Reward Nzuza, intern reserve supervisor at the Zoarvlei Section, removed various alien species
including Spanish broom (Spartium junceum), Caster-oil plant (Ricinus communis), Port Jackson (Acacia
saligna) and Spanish Giant reeds (Arundo donax). The giant reeds concealed illegal structures for several
years and they were therefore cut to discourage illegal occupation (see Figures 11 & 12).

4.1.3 Christopher Singo, reserve supervisor for the Diep River Section, removed various alien species
including Pampas grass (Cortaderia selloana), Red River gums (Eucalyptus camaldulensis), and Water
Hyacinth (Eichhornia crassipes) (see Figures 13 – 16). The water hyacinth clearing programme, which is
administered by a WESSA/Coke partnership project, came to an end on the 28/04/2017.

4.2 The Custodians of Rare and Endangered
Wildflowers (CREW) visited the Milnerton Racecourse
on 26/04/2017 and the Coastal Section on
01/06/2017 (see Figure 17 right).
CREW invited members of the staff and public to join
their expeditions in order to learn about identifying
indigenous plant species as well as monitoring
threatened and endangered flora.
CREW regularly visits portions of the Nature Reserve
including the Coastal Section, Diep River and the
Milnerton Racecourse.
Figure 17. Members of CREW visiting Milnerton Racecourse.
4.3 The Milnerton Racecourse land swap and restoration project was implemented by the
environmental consultant, working for the racecourse, and the contract reserve supervisor, Kyran Wright:
The compacted laterite gravel tracks and lunging rings in the land parcel that will be added to the
Nature Reserve (sites 2 and 3) were excavated and removed. This was done because the laterite
gravel was an artificial hard surface that was added by the Milnerton Racecourse some time ago,
and this covered the natural vegetation. The laterite’s removal will expose the original sand layer
again and thereby provide an opportunity for the natural vegetation to push through.
The site that will be lost to the racetrack re-alignment (site 1) was brush-cut to remove the
vegetation, and the cut material was stockpiled, chipped and then used to spread as mulching on
the bare sand areas in sites 2 and 3. This mulching contains some seeds and plant material that will
introduce nutrients and assist with the establishment of natural vegetation on the bare sand areas.
A layer of the topsoil was also removed from site 1 and used to fill in the excavated tracks and
lunging rings in sites 2 and 3. The topsoil contains the seed bank of the indigenous vegetation as well
as soil microorganisms that are required for nutrient cycling and other ecological processes.
Various bulbs (geophytes) that were previously excavated from site 1 were replanted in sites 2 and 3.
Plant cuttings were taken from living plants in the Nature Reserve. These cuttings will be propagated
into new plants at the Westlake Veld Restoration Facility to be re-planted in the restoration site at
Milnerton Racecourse next year.

5 FAUNA
5.1 Monitoring of fauna included setting of camera traps at Milnerton Racecourse to gather data about
Cape grysbok densities, as well as small mammal trap arrays in the Lagoon section. The trap arrays included
funnel-, pitfall- and Sherman traps and are being used to collect baseline data on fauna species.
5.2 An integrated water bird census was conducted on 21/04/2017. The census was done by the Nature
Reserve team, covering 11 surveys sections. The water birds numbered a total of 3,874 birds comprising of 41
species (see Figures 20 – 22 for details).
15 species with single-figure counts (totalling 43
birds) accounted for 1,1% of the water bird census,

5.5 A Cape Grysbok (Raphicerus melanotis)
drive count census was conducted 26 and
28/06/2017 at the Milnerton Racecourse Section.
Kyran Wright, contract reserve supervisor for the
Milnerton Racecourse, planned the census and used
City of Cape Town Biodiversity Management staff,
students and interns for the survey.
From the results of the survey it is estimated that
there are more than 30 Cape grysbok in the
Milnerton Racecourse Section (see Figures 25 – 27).
In order to protect the Critically Endangered Cape
Flats sand fynbos from over-browsing, some of these
animals will be relocated to other nature reserves.

7.1 Level 4 water restrictions continued…
Other restrictive measures, not detailed above, still apply as stipulated in Schedule 1 of the Water By-law,
2010, available on our website: Know your water regulations. Visit our website to find out how to apply for
exemption from water restrictions. All exemptions granted under Level 2 or Level 3 restrictions are withdrawn
with immediate effect and re-application will not be considered unless otherwise stated above.
Please note that water pressure may be reduced to below applicable regulations or standards
requirements to limit water leaks and may cause intermittent water supply. For further information visit
www.capetown.gov.za/thinkwater or contact us at water.restrictions@capetown.gov.za.
7.2 Rainfall recorded in the Table Bay Nature
Reserve remained below average for most of this
quarter until June, when the measured rainfall at the
Rietvlei Water Area increased to above the average
for that month only. The total rainfall during this
quarter was 147mm at Rietvlei and 111.5mm at
Milnerton Racecourse (see Figures 29 – 30 below).
7.3 A very large storm hit the Western Cape on
7/06/2017, bringing with it significant rainfall and
strong winds. While only 26mm of rain was recorded
at the Rietvlei Water Area in a 48-hour period during
the storm, a very strong storm surge from the sea was
observed pushing into the Milnerton Lagoon (see
Figure 28 right). The storm surge dislodged the
remnants of Commodore II’s wreck and floated it all
the way up to the historic Milnerton Wooden Bridge.

8 FIRE
8.1 A firebreak was constructed at the northern
edge of the Coastal Section adjacent to the Dolphin
Beach Hotel to prevent the possible spread of
wildfires from the Nature Reserve onto the Dolphin
Beach Hotel property and buildings (see Figure 31).
Intern reserve supervisor, Hester Pentz, used the
Nature Reserve team to clear the firebreak.
8.2 Wildfires occurred in several management
sections of the Nature Reserve, including in the
Zoarvlei Section on 24/04/2017 and in the Diep River
Section on 14/05/2017 (see Figures 32 – 33).
Several smaller spot fires also occurred and were all
suppressed by Fire Department and Nature Reserve
staff. All fire boundaries were mapped with a GPS.

9.3.2 Income from visitors at the Rietvlei Water Area during this quarter was only R12,242 from 890
recorded visitors. This is the lowest amount recorded in any quarter since data collection started in 2010,
and less that 20% of the income that was received in the same quarter of the previous year (2016).
This massive decline in income was caused by the closure of the Rietvlei Water Area due to a persistent
blue-green algal bloom since 17/03/2017. The Water Area was re-opened to the public on 30/06/2017.
During this time no fishing or water-sports were allowed, but visitors could still use the bird watching routes
and picnic facilities (see Figures 34 & 35 below).

CITY OF CAPE TOWN QUARTERLY REPORT – 1 JANUARY TO 31 MARCH 2017 19
11.2 Other illegal activities that were addressed in
this quarter include,
(1) illegal footpaths through the Coastal Section
from houses in Sunset Beach,
(2) dumping of building rubble from various house-
building operations adjacent to the Nature
Reserve,
(3) alcohol bottles littering open access areas such
as the Coastal Section, and
(4) illegal cattle grazing in the Diep River Section.
The illegal cattle grazing problem was previously
addressed by meeting with the cattle owners and
the local Councillor, during which the cattle owners
agreed to stop grazing in the Nature Reserve. Since
the meeting, however, the cattle owners have
simply continued to graze their cattle in the reserve.
Figure 42. Illegal footpath through the Coastal Section.
Figure 43. Building rubble in the Coastal Section.
Figure 44. Alcohol bottles collected from the Coastal Section.
11.3 The cattle that are illegally grazing in the Nature Reserve are destroying the natural vegetation and
introducing a range of agricultural invasive species. There is no agreement with the cattle owners that
allows them to utilize the land for grazing purposes.
The Nature Reserve is planning to work with the Law Enforcement Department and the the Cape of Good
Hope SPCA to impound these animals during a joint operation (see Figure 45 below).

12 INFRASTRUCTURE & EQUIPMENT
12.1 Two site cleaning teams were working in the Zoarvlei Section under the supervision of intern reserve
supervisor, Reward Nzuza. The teams were established from a combination of Ward Allocation and
Expanded Public Works funding sources. The employees were selected from the Subcouncils’ job seekers
database, which aims make work opportunities available for unemployed people.
Their main focus was to clean areas where displaced people and illegal structures were removed from the
Nature Reserve, as well as to do alien and invasive plant clearing.
12.2 Other maintenance activities in various parts of the Nature Reserve included (1) repairing holes in
fences, (2) requesting that blocked stormwater and overflowing sewage drains be cleared, as well as (3)
repairing and servicing all the operational vehicles of the Nature Reserve.
