4. Water Levels
CG suggested that water levels are to be kept low during spring tides for ecological functioning. MT reported that the current water levels are good for recreational purposes. JS reported that she has events on the 09 -10 February. MT suggested that she time the events so that they coincide with spring tides. However, JS stated that she had no control over this since she was no longer on the Imperial Yacht Club Committee since Martin Pollock was no longer sitting in the committee. JS will follow up by trying to re-establish communication channels. Rob Maclean is to provide the schedule of canoeists. AS needs to send the dates of the Kontiki to CS. Action: RM and AS
5. Water Quality [see attached report from CH - not attached]
CS reported that water quality reports for December and January had been received, but were not accessible due to technical difficulties. CS to report in next meeting. MT reported that the water salinity was high. CS reported the nitrogen levels are low. CG reported that the water is clear. CG would like to start measuring turbidity again. CS/FH to write an article on water quality results that complied with the International Standards for Recreational Usage for Zandvlei Trust. CS needs to get a hard copy of sewage pumps and generators from CG and forward it to Gavin Lawson and other members. Action: SC, GC, CS/FH, CS.
6. Salinity and Turbidity
The salinity levels are increasing and the waterbody of the vlei and the Marina channels are continuing to emulate a natural estuarine system.
7. Pondweed [Operational Plan]
CG reported that the weed by Marina De Gama and that one kingfisher is still working. CG also reported that pondweed makes excellent compost and therefore suggested that we use the pondweed in many places. CS reported about Bowen’s project where the pondweed can be used in the nursery and stockpiling it is possible. PJ suggested that a chipper can also be used for mulch. However, the suggestion was denied because it involves a private organisation that will not give us chippings for free. CS to investigate possibility of acquiring chipper in future off capital budget COCT. Action: CS
8. Litter traps
TP reported that they took the refuse away from the litter traps. CG reported that there was rubbish by the second pedestrian bridge at Park Island that had been lying there for six months. TP offered to have this litter removed. RW reported that there was litter collecting on the western side of the estuary near the braai area. PJ reported that the holes in the litter net need attention because the litter goes through. CS reported that a meeting will be called to sort out the litter nets. CS also suggested that the use of buoys on the litter nets will be functional because the buoys will keep the litter net steady with the water level. CS to follow up with Parks and Recreation how often they clean up around the estuary. Action: TP, CS
CS reported that GZENR has been proclaimed as a local authority nature reserve. The Zandvlei Trust and CS discussed celebrating this event at the Yacht club in the previous Zandvlei Trust meeting. CS informed the committee that the date of this event is 28 March 2007 at 20:00. Committee agreed to CS taking GZENR off the agenda.
10. Park Island
CG reported that the pedestrian bridges needs to be fixed because the handrails need to be replaced. CS will investigate the extent of work needing to be done and if possible, Zandvlei Nature Reserve staff will undertake the job. CG reported that Parks had not done maintenance in one and half years and that the gate to Park Island is only opened on Monday and is used by a wide variety of people. Gerbils, tortoises and Cape Hares have been reproducing and have been seen on regular occasions as well as a grysbok. CG reported that some pepper trees have been removed from the Island. CS reported that the kikuyu grass has not been sprayed due to time constraints, lack of staff and malfunctioning equipment. CS reported that Zandvlei Nature Reserve staff will be spraying the kikuyu during the summer season. Action: CS
11. Tube Worm
CS reported that F Feldman’s report has been misplaced but will be located for CG. CS also reported that tubeworms were not inspected under bridges lately.
CS reported that eradication is done by Cape Nature and that Cape Nature has not co-ordinated an eradication with CoCT for 2007. It is currently undertaken on Reserve level and needs to be co-ordinated with residents and other CoCT Nature Reserve staff.
13. Channel Scouring/Thesens Bridge
John Coetzee has completed the study. MT reported that he will get the electronic version to forward. TP suggested that a vehicle be on standby when the mouth is opened to test how much material is scoured. PJ reported that the wooden blocks near litter trap are degraded. PJ will show TP what is happening there. TP reported that the concrete is degrading on the sides of the channel. It has been placed as a priority on Tender for this financial year. Action: PJ, TP
