NSW Governor Marie Bashir will drop into the Highlands on September 28 to plant the first tree on the East Bowral site earmarked for the gardens.

The gardens will be established on the corner of Old South and Kangaloon roads taking in the area where an historic skins shed was located until it collapsed about two years ago.

The project is driven by community group Southern Highlands Botanic Gardens Incorporated, with support from Wingecarribee Shire Council.

Mayor Duncan Gair said the planting of the tree was the first step in a long process to make the botanic gardens a reality.

He said council was in the process of preparing a plan of management for development of the site as a matter of urgency.

“The plan will look at what design concepts will be included on the site, such as sculpture trails or a cultural centre with a living museum and how the land will be developed,” he said.

“A draft plan will go on public display for community input into the project before it is brought back to the council for a final determination.

“This is a huge and tremendous asset to the community with a lot of people, including many volunteers, keen to make it work.”

Southern Highlands Botanic Gardens Incorporated committee chairwoman Charlotte Webb said Ms Bashir’s planting of the first tree on the site was an important step in the plans.

“It is a step that shows the Botanic Gardens plan is progressing well,” she said.

The project has already attracted more than 200 “friends” and a fundraising launch in June achieved a “great response”.
