Notes

• Inform the Botanic Gardens Administration Centre (email botanic@mackay.qld.gov.au) 3 days before you intend to use the baseline. This gives them an opportunity to make sure the baseline is clear of overhanging vegetation.
• On arrival at the gardens, report to the Botanic Gardens Administration Centre where you will be briefed on the rules of the gardens. Request a contact telephone number for someone that can organise pruning of any overhanging vegetation. Do not remove or break any obstructing garden vegetation.
• Do not drive star pickets or any other object into the ground in order to secure an umbrella, for example. There is a network of underground irrigation that can be damaged.
• Vehicles are not permitted within the botanic gardens. There is roadside parking the length of Lagoon Street, or bicycles may be used.
• On completion of the calibration, return keys to the Department of Resources and ensure the register has been completed.
