The Krantzkloof Nature Reserve, managed by Ezemvelo KZN Wildlife, conserves 584 ha of the Molweni (Zulu: 'mutual greetings') and Nkutu River gorges that incise the sandstone Kloof plateau in KwaZulu-Natal, South Africa. The reserve conserves coastal scarp forest, sourveld grassland, a cliff face biotope, and aquatic environments along its rivers. Scarp forest is a threatened forest type, protected by South Africa's forests act of 1998, while the grassland is classified as KwaZulu-Natal sandstone sourveld, the most threatened terrestrial habitat in the Durban metropole. The reserve was established in 1950 and was augmented by land donations as late as 1999.SettingThe reserve is situated at 140 to 520 m.a.s.l, and borders on suburbs, informal settlements, and in some of the catchment areas, on privately owned conservancies. The Kloof conservancy manages the Ronald's Kloof stream project, which effectively adds 5 ha to the reserve. The Springside and Iphithi Nature Reserves, in addition to the Everton conservancy, conserve natural remnants of the Molweni and Iphithi rivers' upper catchment.
