A small trial – just 12 square meters – of BioHaven floating islands, provided “on appro” to Durbanville’s Nitida winery, has settled in well. Of course, the 12 square meters provides the surface area that would be achieved by a wetland more than 100 times this size!   The islands, planted with Dietes and other irises, were installed late last year (2012) – into a dam that is topped up with treated effluent during the summer, i.e. a potential site for problematical algal blooms.  As is evident from the photo above, the water is nice and clear – and contains some highly-desirable pondweed (Potamogeton pectinatus) and a small overgrowth of blanket weed (Cladophora species).  Bernhard Veller of Nitida has cleverly positioned a floating circulator next to the island in order to maximize the flow of water past the island and hence achieve the maximum level of water quality enhancement.

The picture below shows the plant growth as of October 2013 – approx. 10 months after installation.

Lush plant growth instead of lush algal growth!!
