Isabella Williams Reserve was identified by Brimbank Council in 2008 as being the site of a District Park with associated infrastructure. Prior to masterplanning, the reserve was undeveloped, never subject to high usage and was used primarily by trail bike riders. In 1998, fencing was installed to remove mowing and reduce trail bike and other vehicle damage to an area of native grassland in the reserve.


The site supports a crtically endangered vegetation community and Pimelea spinescens a critically endangered plant species
