Kinka Reserve is a large Crown Reserve under Warringah Councils care and control. The reserve is approximately 2.9 hectares of which approximately 2 hectares contains high quality remnant endangered Duffys Forest Ecological Community (Threatened Species Conservation Act 1995). The remaining .9 hectares is highly disturbed and currently in a bare state. The aim of the Duffys Forest Residents Association(DFRA) was to make the .9 hectares into an arena for local horse riders to sustainably excersise their horse. This had been and idea that was first thought of over a decade ago but insufficant funding prevented it from progressing. Approval was finally granted and construction of an area started.
On the 11th March 2012, Kinka Reserve was offically opened by the Honourable Robert Stokes MP.
