The Boonanarring Nature Reserve was gazetted in 1991 and covers ~12 500 ha. The reserve is unique, with an ecotone of 10 vegetation types from the Swan region not found together on any other conservation reserves. Boonanarring is home to over 570 plant species, 13% of which are of special interest, many bird species and at least three significant small mammal species (Moore et al 2016).
