Today @CityofCT officials began clearing sludge & bullrushes at Rondevlei Nature Reserve in preparation of the vlei draw-down expected to happen later this week.

Here’s why this is important: Image
1. Rondevlei (250Ha) is a globally renowned birding site. On an average summer day 70 bird species may be seen. It also home to the #ExtinctintheWild Erica verticillata & Cape Town’s only Hippo pod! 🦛

Managing for biodiversity = Managing for ecotourism. Image
2. Hundreds of years ago #CapeFlats vleis would have dried up significantly during the dry summer months. The opening of the sluce gates will allow conservation staff to clear invasive aquatic Water Hyacinth (seen in the foreground). Image
3. The natural flushing of the Vlei will drain excess nutrients and improve water and air quality. The sluce will be closed and the vlei will fill naturally during the wet winter months.

1. Today Deputy Mayor @AndrewsEddie & I helped open the weir at Rondevlei Nature Reserve for the first time since 1998! After a brief boat ride we joined conservation staff in the water to open the sluice gate. ImageImage
2. This draining of the waterbody simulates the natural draw-down that historically happened in this ecosystem. It will also flush excess nutrients from the waterbody & allow conservation staff to remove invasive Water Hyacinth (Eichhornia crassipes). Image
3. We also had a great 1st meeting The Friends of Zeekoevlei & Rondevlei who contribute an immense amount of capital & expertise to these waterbodies. They will be important roleplayers in the Water & Wetlands committee which I chair. Image
