A unique ecology
Getting to grips with wetlands
A wetland is a distinct ecosystem inundated by water either permanently, or seasonally – as is the case at Arderne Gardens.
The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the uniquely boggy, hydric soil.
Wetlands are a critical part of our natural environment. They reduce the impacts of floods, absorb pollutants, and improve water quality. Wetlands provide a unique habitat for a multitude of animals, birds and plants and contain diverse life, supporting specialised plants and wildlife found nowhere else.
Unique wetland plants seen at
Arderne Gardens are the endangered Bloukalossie iris (Ixia monodelph) whose habitat is restricted to the low-lying, wetland habitats of the Cape, and the endemic Watsonia tabularis with flamecoloured, sunbird-enticing flowers – a spectacular sight at Arderne in spring.
