FRIENDS of Holden Flora Reserve's special day on Saturday isn't just about planting trees.
It's also about teaching people about the history of the reserve and surrounding areas.
The group's Bianca Aquilina (pictured) says the places where members plant trees are culturally historic sites.
"There's lots of rare fauna and flora and we are trying to protect what's there in the reserve and along the volcanic escarpments and Jacksons Creek," she says.
"Each time we plant trees [which is five times a year] we look to plant between 250-300 per day."
Ms Aquilina says all equipment will be provided on Saturday and a barbecue will be held afterwards.
