Claudia Gray
 is a Post-doctoral Research Fellow in Ecology and Conservation at the University of Sussex.  Working in collaboration with PREDICTS, her work uses the project’s global biodiversity database to investigate how landscape management can help biodiversity conservation.

In the past, Claudia’s research has explored approaches to sustainable management of oil palm plantations in Sabah, Malaysia.  One of the things she’s found is that riparian buffer zones – the strips of ‘natural’ vegetation left intact along river banks – are not only important for conserving freshwater ecosystems, but that they can help provide habitat for land-based animals, too.

Claudia is now looking to collate information on riparian zone management and legislation across the world.  We spoke to her to find out more. Read more »

Many South African dams suffer from nutrient enrichment, known as ‘eutrophication’.  Around 70% of the water stored in our dams is eutrophic or hypertrophic, indicating that we have a serious problem.  Droplets is seeking recent photographs of algal blooms taken anywhere in South Africa.

If you spot an algal bloom, please send us the photo (high resolution please) with the location and date – all of the images will appear on a special webpage and three contributors will win a prize.

Photos should be emailed to us at admin@dhec.co.za

We look forward to your contributions!
