How Are Surveys Carried Out?
- Firstly – a walkabout on the shore noting everything that is present to build up an overall picture of all the creatures and plants that are there.
- Secondly – transects across each habitat zone, e.g., rock, sand, eelgrass. We lay a line between low and high tide marks and record everything seen for 2 meters on either side or their frequency.
- Thirdly – we take a quarter meter square quadrat and count everything found in it at each different biome along the transect.
- Participants are provided with species lists and illustrated guides.
How Do I Get Involved?
Projects include the Knysna seahorse project, ShoreSearch as described above, the eelgrass project – an intensive study programme carried out by Dr Richard Barnes from Cambridge University on the biodiversity of the sub-surface layer of the eelgrass beds with 5 or more papers published or in publication, studies carried out by Dr Alan Hodgson and students from Rhodes University into the truncated mangrove snail recently arrived in the Estuary and into the invasive Mediterranean mussel to name but two, Dr Allanson’s study of the endangered false limpet, Siphonaria compressa, the topically very important investigation into the recent invasion of sea lettuce (Ulva lactuca) – a joint project with the Nelson Mandela Metropolitan University in Port Elizabeth, Project KEMP which is monitoring the quality of water in the estuary through fixed data recording stations and a survey of baiting practices being undertaken by Dr Carol Simon and Alheit Du Toit from Stellenbosch University.
