Stingray Swamp Flora Reserve (SWFR) is located immediately north of Penrose township in the south-western region of Wingecarribee Shire. The reserve is primarily surrounded by the (Penrose State Forest ), which is a commercially active plantation forest administered by the Forest Corporation NSW. Pine species dominate the state forest with a mix of native vegetation types in isolated pockets and adjacent areas. Stingray Swamp Flora Reserve belongs to a larger wetland complex known as the Paddy’s River Wetland Complex (PRWC). These wetlands also form part of the Paddy’s River sub-catchment, which belong to the larger Hawkesbury-Nepean catchment. Historic use of this area has mainly been that of pine plantation, agriculture and mining activities. The forest is publicly accessible and therefore is a site of mixed recreational activities. ==Geology, geomorphology & soils== The reserve is located within a landscape of rolling low-to-medium profile hills with minimal geologic outcropping. Predominant geologic units are Hawkesbury Sandstone, Berry Siltstone and shale units. Hawkesbury sandstone is the prominent geologic unit and can be seen at several outcroppings especially along watercourses.〔Australian Government (2014) Temperate highland peat swamps on sandstone.

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.〔Australian Government (2005) Temperate highland peat swamps on sandstone.

Geomorphic characteristics as a swamp mark it is an important hydrologic and fluvial unit within the landscape. SWFR is situated within the upper reach of Paddys River, which forms part of the Wollondilly sub-catchment. The Wollondilly sub-catchment is a major component of the southern rivers sub-catchment; located within the Hawkesbury-Nepean catchment. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stingray Swamp Flora Reserve」の詳細全文を読む スポンサード リンク
