Fresh water runs through Alberts Farm
19 September 2005

THE only artesian spring in Gauteng is tucked away under Northcliff ridge in Alberts Farm, the second biggest green lung in Joburg.

The rocky beginnings of the stream from the artesian springGAUTENG has a single artesian spring - on Alberts Farm in Albertskroon in Joburg's northwest suburbs - spurting a fresh, clean trickle of water throughout the year.

The Alberts Farm Conservancy is a 90ha piece of gently slanted land up against Northcliff ridge, the second largest green lung in the city after Delta Park. It is an ecologically significant area, with a high diversity of indigenous grass and shrub species, as well as several dams, a wetland, a marsh and, of course, the spring and stream.

The conservancy is in the middle of dense suburbia, providing local residents with a welcome green lung. It is a popular weekend picnic area, and is used every day by dog walkers.

Two slanted rock formations form the spring - the south-facing shale meets the downward-sloping quartz rock from the north, forming an impenetrable basin in which the water forms. It is then forced, under pressure, to the surface.

A normal spring is formed when underground water, moving through permeable layers, hits an impermeable layer and is forced to the surface.

"The spring runs throughout the year," says Noel Perry, the chairperson of the Friends of Alberts Farm Conservancy Management Committee, "but flows more strongly in summer, after the rains."

Bubbling out of the ground in a rocky, mini forest in the middle of the park, it feeds into a soccer field-sized dam. This dam drains from one corner through a marshy area into a lily pond about 100 metres below it.

It is a small, quiet splash of water that is now choked with parrot feather weed. Further down the hill is a stream and a wetland, a source of the Montgomery Spruit, which flows towards Parkhurst, joining with the Braamfontein Spruit.

There are fish in the dam, which is used on weekends by church groups for baptism. Concrete circles have been created in the park for these groups to use.

Perry says the sound of drumming and singing echoing across the valley on Sundays is pleasant. "We live in Africa; the beating of drums is natural."

The farm dates to the 1890s, when, it is thought, Hendrik Abraham Alberts leased 114 acres from the owner of the large farm Waterval. The original farmhouse is long gone, but the family cemetery exists, a lonely, fenced presence in the parkland.

Perry takes me up to a shaded area. A line of oaks on one side and a cluster of blue gums across from it suggest the possible location of the farmhouse.

Alberts Farm Conservancy

THE entrance to Alberts Farm is on the corner of 8th Street and 6th Road, Albertskroon. Entry is from sunrise to sunset, but because the conservancy is unfenced, walkers should be cautious outside of those times.

A small circle of concrete was a well, he says. Now covered, it further reinforces the feeling that the farmhouse must have been nearby, commanding a view down the valley to the southern ridges of Johannesburg.

It is a tranquil spot, standing among the trees with a gentle breeze blowing up the valley. There is no trace of any cultivated fields, although Perry says the Alberts family farmed mealies.

In 1946 the family sold 45 000 square metres of land to the City, for £18 500, specifying that the land must be kept for public use.

East of the wooded area are unusual rock formations, which Perry believes relate to the Vredefort Dome at Parys, 100 kilometres south of Joburg. The dome is a vast basin formed when a meteorite hit the earth some two billion years ago.

Flora and fauna
About 139 different bird species have been spotted in the conservancy, which has a red data plant and a swathe of natural Transvaal grass which, according to Perry, deserves protection.

The committee represents the surrounding suburbs of Northcliff, Greymont, Albertskroon, Albertsville and Westbury. It spends some of its time removing weeds like kakiebos, blackjacks and bugweed, perpetual problems in any areas that birds fly over, dropping seeds.

The park is dotted with trees - 70 different species have been identified, 35 indigenous, 35 exotic. In addition, 29 grass species have been found and 78 species of shrubs (18 of which are exotic).

Alberts Farm, unlike other parks such as Zoo Lake, is deliberately left largely in its natural state, says Alan Buff, the general manager of technical support and training at Johannesburg City Parks.

"We don't manage all parks like a bowling green, but rather we look at the natural environment to maintain the biodiversity of the park." This principle also applies to Delta Park.

Buff says that in the 1970s, when Delta Park was being established as a public park, white guinea fowl, ducks and small animals (and several springs) were found in the long grass, which was subsequently left uncut for the wildlife.

Several years ago the City undertook a vegetation survey of Alberts Farm, done by Wits University. Its recommendations included carefully monitoring the wetland, labelling the trees and cutting down some of the alien trees, controlling dumping, building a bridge over the stream, building raised walkways over the wetland, constructing educational boards, and, once a fence was erected, charging an entrance fee.

The survey points out that Alberts Farm is a catchment area, feeding the Montgomery Spruit, which forms part of the larger river network of the city and should therefore be managed in an eco-friendly way.

Eventually the committee would like to introduce zebra and small buck into the space and construct bird hides. An Olympic cross-country track is also a long-term plan, as are mounted patrols.

Quad bike and 4x4 vehicle owners driving over the precious marsh area below the dam present a particular problem.

The farm has added significance because on its north-eastern edge is an "eeufeesgrond", probably set up originally as a festival area in 1938 for the centenary celebration of the Great Trek, but used throughout the year by the Afrikaans community for various festivals and fairs.

Nowadays there is a small community hall marking the spot, owned by the City. Perry is hopeful that when the lease ends soon, the conservancy will take it over and create a leadership camp. School children would be able to attend weekend camps and learn about the natural surroundings.

The committee has great plans. A restaurant would also be built just below the eeufeesgrond; the money generated from this would maintain the leadership camp and contribute to the upkeep of the conservancy.

The restaurant would overlook the dam, making for a tranquil place to eat and enjoy the view, taking in Melville Koppies and the city in the far distance.

Because it has a long history of being disturbed, the eeufeesgrond is of less ecological significance, making it the right spot to develop.

The committee's long-term plan is to fence the entire conservancy and allow entrance through six gates, one of which will remain open for 24 hours. A R40 000 donation has already paid for parts of the perimeter to be fenced.

Several events are organised throughout the year by the committee, like a spring fair, a kite-flying day, and events on New Year's Day.
