HEYTESBURY DISTRICT LANDCARE NETWORK
St Patrick's Day Fires 2018
On St Patrick’s Day 2018 the Heytesbury District experienced severe fires that burnt more than 40,000 Hectares of Public and Private land. The Department of Environment, Land, Water and Planning coordinated $620,000 of rehabilitation works within the district with funding and support coming from local councils, committees of management and community groups.
HDLN's role in providing support to Impacted landowners, Government and Non-Government organizations during the recovery phase has been documented in the booklet 'Devastation to Restoration', available by clicking on the image or in hard copy from the Timboon office.
The ecologists Landtech Consulting assessed the impact of the drone on revegetation/recruitment, comparing images taken from drone flights in 2020 and 2022.

In essence drone reseeding is a successful approach with the results -
"1. Increased indigenous vegetation cover over the recent two-year period (2020-2022); 2. Increased cover with assisted drone seeding; and 3. Increased cover with increased seed concentrations."
This information will be important in climate adaption management. It demonstrates that drones can undertake important work in fire affected peat swamps in a safe and non-intrusive way, limiting exposure to risk for staff and contractors.
Drone Reseeding of Lake Cobrico
One of the final projects in the rehabilitation program was the aerial seeding in April at Lake Cobrico, a swamp wildlife reserve near Camperdown. Due to concerns that the lake’s ecosystem might not be able to regenerate naturally after the high intensity fires, drones were used to distribute 32 kilograms of native seed over 40 hectares of the burnt lakebed.
