Ferny Creek contains a wide range of microclimates and aspects, and as a result the flora is similar to that of the larger Dandenong Ranges as a whole. The Dandenong Ranges National park including Sherbrooke Forest, contains large areas of native vegetation and is dominated by a mix of wet and dry Sclerophyll forests. There are small pockets of wet temperate rainforest in the deeper gullies (bordering Sherbrooke, Mast Gully and Ferny Creeks).
