Nareen Wetland, located at North Narrabeen, is a freshwater wetland covering an area of approximately 8ha. The reserve contains good habitat value and provides important connections for species inhabiting larger habitat areas to the north and south.

Vegetation

Vegetation communities within the reserve comprise of Swamp Oak Floodplain Forest and Sydney Freshwater Wetlands which are both listed Threatened Ecological Communities (TEC's) under the Biodiversity Conservation Act 2016. Over the years the wetlands have been heavily impacted by urbanisation with hydrological changes and alterations to the land. The Sydney Freshwater Wetlands TEC is dominated by Typha orientalis with isolated patches of Persicaria spp and Ludwigia peploides. There are two areas of Swamp Oak Floodplain Forest within the wetland. Current bush regeneration program's within the larger western patch of the reserve have shown good results with the regeneration of a number of native species including Dianella caerulea and Stephania japonica.

Fauna

Nareen Wetland supports a number of local fauna species including ring-tail possums, long nose bandicoots and an abundance of birds. The dense weedy vegetation areas on the edges of the wetland provide important habitat for fauna including small bush birds such as Variegated Fairy Wrens.
