Racecourse Flora Reserve is situated between the towns of Mullalyup and Balingup, approximately 2.5 kilometres northwest of Balingup. In 1999 the Balingup community identified bushland considered worthy of protection in three adjoining reserves. These ﾠreserves contained abundant flora and areas of conservation value. The reserves included the site of the old racetrack and gymkhana ground. The three reserves are now amalgamated and vested with the Shire of Donnybrook-Balingup as a reserve for the purpose of conservation and recreation. A copy of the herbarium for the reserve is held by the Balingup Friends of the Forest. The herbarium contains photocopies of the plants identified on the reserve, along with their botanical names.
