The mountain is surrounded by deep valleys, where riparian forests of Manna Gum dominate. It is also called "Manna Gum". The Frankston spider orchid occurs in heathy coast manna gum woodland, on the Mornington Peninsula. Black Sally and Manna Gum are found in the cooler gullies and frost hollows. Historically, the honeyeaters have also occupied manna gum riparian forest.
