Mini SASS Course – 01 April 2009.
Alice (Ally) Ashwell co-ordinated and organised with Jeanne Gouws (Cape Nature - Stellenbosch) to present a course to interested people. Group representatives from Table Mountain National Park, WESSA, Two Oceans Aquarium, SANBI (Working for Wetlands), Zandvlei Nature Reserve, Noordhoek NGO's, and Zandvlei Trust.
We met at Lismore Road, Tokai and
walked down to the Prinskasteel River at the castelated weir, near the M3
motorway to do a sample test. The weather was hot and sunny, with no wind.
Jeanne Gouws introducing the course to the group of about 25 enthusiastic participants.
Note making and questions. Explaining the water flow direction and net position.
There is technical detail to remember and adhere too, so as to achieve acurate and consistant results. This is not too difficult to understand or remember, obviously practise will improve the results depending on the location and site.
"Twisting in the mud" to release mud dwelling creatures. Collecting the samples.
We were all surprised to see the amount of life that came from the water when observed in the trays. Jeanne explained that the higher the species count the better the quality of water is. Quanity of species is not what is really looked for, a diverse variety of species is wanted. Hence the importance to conserve and work towards increasing the biodiversity of all species, big and small.
We saw a large mud crab. The net sample being emptied into the tray.
These are the small creatures very few people see, let alone think about or consider in busy our daily lives. These creatures are often at the begining of the foodchain and important indicators of the health of the system or habitat.
There were all sorts of small swimming creatures. Plenty small fish were evident.
This group of keen observres on their knees. It was busy at the weir.
Other wildlife was observed, a Gymnogene being harrrassed by a pair of gulls and a Peregrine Falcon flew overhead. A pair of nearby resident horses with a rider (Cattle Egret) were roaming in the grass.
