One of the few freshwater marshes in Gloucestershire, it contains a unique collection of attractive marshland plants. The sloping pasture is a fine example of typical Oolitic limestone grassland. Access is by permit only.

Brassey Nature Reserve is situated on the northern side of the Windrush Valley approximately 3km north-west of Bourton-on-the-Water, Gloucestershire. The reserve is owned by Thames Water Ltd and has been a Gloucestershire Wildlife Trust nature reserve since 1965. Its importance for nature conservation was recognised in 1954 when it was included as part of the Brassey Reserve and Windrush Valley Site of Special Scientific Interest (SSSI)        
The reserve is comprised of two main habitats of interest, unimproved limestone grassland and marsh / mire. The reserve is rich in biodiversity with 1,171 species recorded since 1965, including many Red Data Book, Nationally Scarce and national and county Biodiversity Action Plan (BAP) Priority species.  
Brassey is unfortunately closed to the public as it is a water abstraction site with water cleaning facilities.

Access may be arranged for groups or come along to an open day, see events for details.
