Proposed New Notification Form • Combines Earth Sciences and Cultural Heritage
notifications For Earth Sciences issues: • Includes the old Geoscience “Triggers” document in the
notification form • Reduces the instances when a notification is required o for karst categories C and D, if no karst features known o for moderate-high erodibility soils o for large terrains in the TGD, e.g. SOP19 o if advice has previously been given, e.g. thinning coupes o for land exceeding the landslide slope threshold (10%
rule and nos sign of mass movement) Note that the up-to-date version of the Tasmanian Geoconservation Database is now in the Natural Values Atlas (NVA) – use this version!
![Page 4: FPO Refresher Course - fpa.tas.gov.au · FPO checks the Conserve Aboriginal heritage database for every FPP ... FPO Refresher Course Author: McIntosh, Peter Created Date: 9/9/2014](https://reader035.fdocuments.in/reader035/viewer/2022062414/5f03102c7e708231d40759cc/html5/thumbnails/4.jpg)
For cultural heritage issues the new form: • summarises the Resource Guide procedure for deciding
when to notify • eliminates the notification requirement for thinning coupes -
if advice has already been received, still applies, and can and will be implemented
• note that mapped predictive zones are no longer used – work out whether an area is a “high” zone using the Resource Guide triggers
Please let me know if you think the draft new form is workable or have suggestions for improvement

Aboriginal heritage • Aboriginal Relics Act 1975 – recognised as needing revision • Aboriginal Heritage Protection Bill 2013 o would require management plans for “high impact”
activities o unclear whether forest operations would be exempt o Bill’s passage through State parliament is uncertain
• Issues affecting FPOs: o future status of Conserve Aboriginal database o possible requirement to consult AHT (TASI) database for all
new FPPs o revision of Resource Guide in conjunction with AHT,
foresters and other stakeholders o FPO training in Aboriginal cultural heritage (Note that Conserve has incomplete coverage on private land)

Reminders • make sure that an FPA-endorsed Aboriginal heritage
FPO checks the Conserve Aboriginal heritage database for every FPP
• Check whether Resource Guide triggers apply • Aboriginal heritage is not just artefacts

Please use up-to-date forms available on the FPA website: click on FPA Services to get to:
http://www.fpa.tas.gov.au/fpa_services/planning_assistance/heritage_and_landscape Also note the link to the Tasmanian Aboriginal Site Index (TASI) form on the FPA website – this is the form to use
![Page 9: FPO Refresher Course - fpa.tas.gov.au · FPO checks the Conserve Aboriginal heritage database for every FPP ... FPO Refresher Course Author: McIntosh, Peter Created Date: 9/9/2014](https://reader035.fdocuments.in/reader035/viewer/2022062414/5f03102c7e708231d40759cc/html5/thumbnails/9.jpg)
• Use this form for all “new” Aboriginal sites or updating of information
• Only photograph artefacts in place – no disturbance allowed
• Send photos as separate jpg or tif files
• Once completed send to FPA
• FPA will get the site recorded on Conserve and will send form and photos to AHT for listing on TASI

Notes and photos bring a site “alive”
“The person who lived there's name was George Seabourne (Shanna Seabourne ). He lived there with his second wife Violet. They lived there 70+ years ago & then moved to Dover.”
“George worked on the tramline in the Esperance bush. He travelled to work on the Raminea Loco that was driven by Michael Casey’s father.”

• Burning by Aboriginal people may have been responsible for large fires that occurred c. 13 500 years ago
• This could have been a response to the expansion of forest that started as climate got warmer and wetter after the Last Glaciation
