Stingray Swamp Flora Reserve (SWFR) is located immediately north of Penrose township in the south-western region of Wingecarribee Shire.

Pine species dominate the state forest with a mix of native vegetation types in isolated pockets and adjacent areas.

[1] Nattai tableland and Penrose variants form the predominant soil landscape units within and adjacent to the study area.

The soils types are mostly swamp and floodplain deposits that consist of clayey sand with heavy organic and poorly draining characteristics; quaternary alluvium overlies the majority of Hawkesbury sandstone.

The geomorphic character of SWFR is identified as “Temperate Highland Peat Swamps on Sandstone” and is classified as an ecological community.

Stingray Swamp is composed of a rich array of flora and fauna, which is influenced to a large extent by the underlying biophysical and geomorphic character.

[3] The flora of the immediate region consists of dry sclerophyll forest, montane peat shrubs and Cumberland plain woodland species.

Stingray swamp exhibits a distinctive and rich mixture of heath, shrub, grasses and fern species.

[4] Of note are the following species that area listed at State and National levels: The cultural values of SWFR are not present in any structures or sites of historic importance.
