DFFE RAMSAR site visit and Ramsar information system (RIS) update

31 Aug 2024 by Keith Spencer, July 2024

The Convention on Wetlands is a global intergovernmental treaty that provides the framework for the conservation and wise use of wetlands and their resources. The Convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975. South Africa, together with almost 90% of United Nations member states from all the world’s geographic regions, have agreed to become “Contracting Parties” committing to designating sites as Wetlands of International Importance.

Since then, South Africa has declared 30 RAMSAR Sites under the Convention, with the most recent being the Berg Estuary in the Western Cape. CapeNature manages seven of the 11 RAMSAR sites in the Western Cape, namely De Hoop Vlei; De Mond; Dyer Island; Bot-Kleinmond Estuarine System; Dassen Island; Berg Estuary and Verlorenvlei Estuary.

This specific site visit and the associated RIS update discussion focused on two specific RAMSAR Sites managed by CapeNature in the Western Cape, namely De Mond Ramsar site (Heuningnes Estuarine Lake system), part of which is situated in the De Mond Nature Reserve, and De Hoop Vlei, a unique freshwater coastal lake situated in the De Hoop Nature Reserve and adjacent to the De Hoop Marine Protected Area. Both sites are situated in the south-western Cape.

On the 24 and 25th of June 2024, a Department of Forestry, Fisheries and Environment RAMSAR delegation joined the local CapeNature RASMAR Site Management teams of De Hoop Vlei and De Mond Estuary for an exciting field visit and associated discussions. CapeNature is required to update the RAMSAR Site Information Sheets (RIS) every 10 years. The RAMSAR RIS platform enables CapeNature to share important information on each existing site with all stakeholders while at the same time committing to explore opportunities to expand the existing sites to include functional ecosystems.

De Mond RAMSAR Site, declared under RAMSAR Criteria 1, 2, 3 and 4 aims to extend the RAMSAR status to include the full Heuningnes estuarine lake ecosystem. CapeNature in partnership with SANParks, is working towards expanding the RAMSAR site to include the Soetendalsvlei wetland which forms an integral part of the estuarine lake system. This will effectively increase the size of the RAMSAR site from 918ha to 3172ha. CapeNature implements the Heuningnes Estuarine Lake estuary management plan (EMP) developed and approved in line with the Integrated Coastal Management Act and the National Estuarine Management Protocol as well as the estuary mouth maintenance management plan (MMP) which was developed in line with the National Environmental Act. Both management processes aim to facilitate the functional link between the different catchments, Soetendalsvlei, the estuarine lake system and the ocean. An estuary advisory forum provides a platform for continued transparency with all stakeholders.

De Hoop RAMSAR Site, declared under RAMSAR Criteria 1, 2, 3, 4, 5 and 6, is a freshwater ecosystem. In addition to effective management and monitoring, the aim is to expand the RAMSAR site to include the upper portion of the wetland, which is currently being managed by the Fynbos Trust. This would result in an increase of the current size by including shallow portions of the lake system which generally dry up early in the summer season and, in doing so, provide important shallow feeding grounds for migratory bird species. In the long term the aim is to include areas on the east and west of the wetland in conservation areas.

With the target of the Global Biodiversity Frameworks 30% protection by 2030 (30x30) in mind, the DFFE/CapeNature team put their heads together to use the limited time to work through the two RIS documents towards the final updating process and to agree on a way forward to plan short-, medium- and long-term goals of improving and expanding protection of these critical habitats.

The result has been widespread damage, with 85% of all reserves reporting at least some form of damage. The Cederberg region has emerged as the hardest hit.

Ongoing efforts to safeguard the Critically Endangered Tradouw redfin through monitoring

The Critically Endangered Tradouw redfin (Pseudobarbus burchelli) is one of South Africa’s most range-restricted freshwater fishes. It is endemic to the Huis–Tradouw River catchment near Barrydale in the Western Cape. The species is listed as Critically Endangered due to its small and fragmented distribution, threats from invasive fish species, pollution, water abstraction, and habitat degradation.

CapeNature urges public not to unnecessarily remove chameleons following Garden Route storms

Members of the public are urged to assist wildlife responsibly following recent severe weather events in the Garden Route, and to avoid the unnecessary removal of chameleons from their natural habitat. Following severe storms experienced in the region over the last two weeks, many trees have lost branches or fallen entirely. As a result, some small animals have been displaced from their natural habitat.
