Brief_description
The wetland area is on Moddervlei Farm dubbed Nuwejaars River wetland or affectionately known as Liohans Moddervlei. It is located approximately 6km south from the small town of Elim, along the R43, directly opposite the Black Oystercatcher Restaurant. Nuwejaars River Wetland is situated runs across two farms, Moddervlei and Hazevlakte, and both are part of the Nuwejaars Wetlands Special Management Area (NWSMA). Nuwejaars Wetland Special Management Area (NWSMA) operates under a section 21 not for profit company, the Nuwejaars River Nature Reserve (NRNR). The organisation is situated on the Agulhas Plain and covers approximately 45,000 hectares. Membership consists of 25 landowners and include the community of Elim as well as the Department of Rural Development and Land Reform. The overriding objective of the organisation is to maintain the high productive agriculture of the area with all its work opportunities and food production, while conserving and managing the natural areas of rivers, wetlands and endangered fynbos as a complete unit, an area of approximately 22,000 hectares. The Nuwejaars River Wetland is Palmiet riparian wetland, dominated by palmiet, Prionium serratum, that forms a dense stands to 2 m tall in acid-water streambeds. Perennial acid water streams that have gently flowing water with a gradual incline with deep sandy banks. It plays an important ecological role in binding riverbanks and prevents the scouring of riverbanks. Influenced by catchments management upstream. Alien vegetation (primarily Acacia saligna and Acacia longifolia) and the subsequent scouring of rivers are a major threat to this unit. The main problem with alien vegetation is that when flooding occurs the alien trees tend to be uprooted and this loosens the sand banks and the process of scouring and erosion of banks occurs. This is a widespread problem in Cape Rivers. Currently the wetland area is primiraly dominated by dense alien vegetation growth to the east, and the wetland is largely intact and pristine to the west. A rehabilitation project for the wetland area is due to start in 2018.
