Nature

Silver Lakes golf estate was the first of its kind in South Africa. It is situated in the east of Pretoria in South Africa's Gauteng province, in a highveldt climate and vegetation environment. South Africa is not only a semi arid country, the region where Pretoria is situated gets only summer rain falls of about 300 mm/year. Pretoria is one of the largest cities in South Africa therefor the golf course is with in the city, limits, but has its own small game reserve and the estate and golf course endeavor to plant indigenous trees and hardy plants, still with a 'Colonial' flavour since this is the theme the original developer based and designed the buildings and gardens on.

The golf course and residential development was partly developed in a the river bed of a side stream of the Pienaars river and therefore has numerous larger and smaller dams built in this stream. One large dam is in the game reserve and the rest forms the lakes around which the course was built, with the most beautiful 'silver' sunsets over the water.

Hence the name 'Silver Lakes'.

This golf facility consults the following individuals / organizations regarding its grassing plan:

  • Peter Matkovich Golf Course Architect

This golf facility is making the following efforts to manage the playing quality expectations of customers:

Activity Description
Establishing clear internal policies for irrigation, fertilization, colour, cutting heights, overseeding etc Non spraying of rough and out of play areas to increase bio diversity. Flowers which may be deemed weeds on a golf course are allowed to grow in these areas. Members appreciate the effort to promote bio diversity and reduce inputs
Promoting the playing quality values of more naturalized turf, particularly fairways and semi-rough Kikuyu is allowed to go dormant in winter, fairways are now irrigated in winter, semi rough is not irrigated
Promoting the financial benefits of presenting sustainable surfaces We intend to schedule a presentation to our members and promote the financial benefits of a sustainable golf course.
Improving customer understanding around greens maintenance We have begun a programme of lectures for our members on maintenance practice's and have white boards at clubhouse detailing daily work.

Conservation & Enhancement

This golf facility is undertaking the following activities to conserve landscape character:

Activity Description
Allowing seasonal variation of course coloration and texture During the South African Highveld winter Kikuyu grass experiences a period of little or no growth and turns brown. We allow this to occur on fairways and roughs to help preserve water supplies.
Appropriately matching mowing lines to contours Green and tee surrounds and complexes are mown so as to follow mounding and contours for the best natural presentaion
Protection and restoration of historic features Although there are no historic features near or on the golf course the historical sites in the game reserve are of great importance to all and are kept as separate open areas.
Discreet on-course signage and furniture Signage and furniture are embedded into the turf of area such as tees. Use of natural granite stone as well as signage which forms part of the estate corporate design are used. a process of replacing all golf course furnishings with recycled material furnishings has already been started and will be implemented fully in the next few years as old furnishings needs replacing.
Conservation of specimen trees The naturally threesome of Acacia caffra( Thorn Trees), Rhus lancea and Celtis africana (white stinkwood) are not only well represented in the new trees planted on the golf course, but the conserved pockets of natural vegetation throughout the golf course are well representative of these species.
Screening and softening unsightly man-made features Trees are planted in aesthetically pleasing areas, close to houses to screen the golf course from too much visual interference by houses. also protecting the homes agains stray golf balls.
Simplification and development of planting materials and the natural environment on the estate as well as on the golf course a program of de-cluttering the past 2 years has brought us to a cleaner canvas to develop the special features of the estate and golf course. New focal point and use of new planting can now be implemented. This includes features with natural indigenous grasses and developing the natural vegetation pockets through-out the estate and golf course. Not only providing an aesthetically integrated and pleasing landscape, but also habitat for the fauna occurring on the estate.

This golf facility is undertaking the following activities to improve the landscape ecology of the golf course:

Activity Description
Increasing the size of habitat patches The naturally occurring features of rocky outcrops, together with clumps of trees and veldt provides habitat for many animals on the estate. Not only do we have these animals in the game reserve, but some occur on the golf course as well. Especially the bird life on the estate is alive and well. A bird list of the birds occurring on the estate and spotted by the bird watchers of the estate is on the web site.
Connection of internal habitat patches Although the golf course 'flows' through a large estate of more than 1660 homes the inclusion of naturally occurring vegetation together with the planting of focal areas of decorative indigenous grasses helps combining the otherwise dislodged elements into a whole where not only the visual experience are one of a pleasing landscape, but the naturally occurring fauna has places to hide and roam during times of safety.
Connection of patches with external habitats Habitat patches on the Silver Lakes golf course are usually where natural veldt, with indigenous trees and sometimes even rocky outcrops were left in their natural state. These patches of habitat are more often than not being claimed by buck who escaped from the game reserve and are now staying in these patches permanently. taking shelter during the day and roaming the golf course and the home-owner gardens at night! the golf course itself and the stream around which it is built actually acts as the connection of these patches. The weirs and bridges crossing the stream acts as links sometimes
Creation of habitat corridors Habitat corridors are naturally created on the golf course by the stream with its lakes flowing through the estate and the golf course. even the rough of the golf course serves as feeding areas for some of the fauna on the estate. the next phase of development is to include more of these natural veldt and focal decorative grassed areas around the golf course. this will not only enhance the free-flow of fauna via these corridors, but will create an interesting and more pleasurable golfing experience.corridors
Avoidance of habitat fragmentation Although the nature of a golf course are one of segmentation. 18 pieces of segmentation to be exact care are taken to interlink these segments of the above habitat areas through larger vegetation patches such as the feature decorative grasses and the naturally occurring veldt grass and trees.these 'patches' of vegetation flows form the one segment to the other to interlink them all in the end. providing the above corridors of possible movement for the natural fauna.
Improving and diversifying habitat edges The creation of new and improving the existing habitat areas for the fauna around the golf course are being explored and implemented as one reads this document. Creating a natural transgression of flow from the edge of these habitats to the golf course. This is an important part of e.g. creating a habitat for the Cape Clawless Otter that was rescued in one of the lakes to be put back into nature on the course. The plan is to work together with the NGO, FreeMe, to not only rehabilitate the Silver Lakes otter, but possibly re-establish other animals in our Silver Lakes environment as well.

This golf facility does not undertake activities to improve the quality of habitats on the golf course.

This golf facility is undertaking the following activities to conserve and enhance biodiversity on the golf course:

Activity Description
Provision of nesting and nectar for pollinators Owl Houses are being installed in the game reserve as well as the in special areas along the golf course. The home-owners on the estate not only feeds the guinea fowl and Egyptian geese on the estate and golf course, but also create numerous feeding stations such as for humming birds and our very special 'Go-Away' bird (kwe voel). The planting of indigenous trees and plants also provide fruit for these birds.
Installation of nest boxes Owl houses and tree trunks for wood peckers area being installed by home-owners through-out the estate.
Provision of feeding tables The same as above. the more than 1660 home-owners provide ample feeding stations for the birds
Control / management of alien species Egyptian Geese is a problem and sometimes up to 200 geese are present at once on the estate in single spots. This leads to infighting, therefore the golf course has a program of removing and re-establishing elsewhere for the Egyptian geese.
Provision of hibernation areas The hibernation areas for the few animals which hibernate occurs naturally.
Creation of micro-habitats (eg log and stone piles) The packing of rocks for the rehabilitation of erosion of the dam sides also create breeding space for fishes, as well as birds. Originally when the two large dams were built island were created in the dams to act as safe breeding space for birds. At the moment the installation of artificial floating islands for the purpose of creating more breeding space for birds and fish are being explored. Silver Lakes were part of the original experimental phases of these floating islands.

Water

As mentioned in of the other sections, Silver Lakes Golf Estate has been developed around a side stream of the Pienaars river. We are therefore in the position to have rainwater stored int he dams/lakes of the estate for irrigation. Several boreholes serves as back-up in times of little water. several attempts to save water, such as watering at night are being implemented, but is unpractical since the existing system is a hand managed system. The budget for a new and upgraded irrigation facility and system is part of the suggestions for the 2015-2016 budget. Then the aim is to do watering with NO losses other than natural losses such as evaporation. And even this we would like to curb, by irrigating at night.

We are currently exploring ways to reduce water consumption

Purchasing Policies

This golf facility undertakes the following ethical / environmental purchasing activities:

Activity Description
Measures to avoid waste at source Measuring of all chemicals are done as accurately as possible with calibrated equipment. This extends to the use of fertilizers. Chemicals and fertilizers are only applied at published label rates. This reduces usage as well as reducing the chance of resistance which leads to increased usage of chemicals. We also vary chemicals to also reduce the chance of diseases, and pests building up resistance.
Use of local suppliers We only source from local companies with the correct BEE credentials ensuring that the benefits are filtered down as far as possible.
Use of local products Local products are used where possible. Hand tools such as spades, rakes etc. are exclusively local products. We go to great lengths to find alternatives for any imported products where possible. This brings our overall maintenance costs down as well as supporting local industry.
Selection of certified products Only registered chemicals and fertilizers are used. As far as possible no generics as in some instances these generics are not as effective as the registered products leading to wastage.
Use of recycled and recyclable products A lot of the hand tools and hardware on the course, rakes, dustbins, hazard stakes are manufactured from recycled plastic.
Selection of products that feature minimal packaging We do a bulk buy on our chemicals in the beginning of the season to take advantage of pricing and with this the chemicals are packaged in bulk containers, reducing the number of plastic containers and bags.

This golf facility undertakes the following actions to optimize pesticide use:

Activity Description
Selection on the least toxic and lest persistent products Only registered products at exact label rates are used when absolutely necessary to combat any pests.
Selection of appropriate products for specific pests and diseases Only products that are registered for the control of the pests posing the problem are used.
Spot-treatment with handheld sprayers and wipers Any localised outbreaks of Fungi on the greens are spot treated if the outbreak doesn't pose a risk to the playability. Weeds in rough and cart paths are controlled by the application of the necessary chemicals with backpack sprayers.
Calibration and testing of sprayers Calibration on the ride on sprayers is performed once a month. Nozzles are replced once a season to eliminate wear and ineffective spray patterns
Use of shrouded sprayer and anti-drip nozzles Industry approved, market leader nozzles are used. The wind is not normally a factor for spraying, however no applications are made when there is any wind movement at all.
Non-chemical weed control Manual removal of Kikuyu, goose grass of areas where it has encroached onto playing surfaces where it is not desired.
Use of organic and biological products to improve plant health and resistance. The health of the growing medium is paramount. Applications of organic rich materials are applied to areas where growth is not optimal to improve these areas. Natural, slow release N products are used as much as possible. Applications of Gypsum/Bonemeal to heavy clay soils to improve soil characteristics. Decompaction of playing surfaces twice a year to improve air flow and water, nutrient infiltration.
