- 7. Post burn Ohhhhh What have we done!!!
- 8. Post burn – first rains Currently
- 9. The Blooming 2015 Actinotus minor Anyone? Bandicoot diggings Herbivore scats Acaciasuaveolens Banksiaericifoliasspericifolia Grevilleasericea
- 10. Beyond the Bloom – the sites’ future Ongoing volunteer bush regeneration Consideration of further Allocasuarina treatment Ongoing informal site monitoring Additional burns in light of ecological and hazard requirements
- 11. Service Trust Respect Innovation The Blooming Lessons Community consultation requirements may be greater than expected Examine your site and identify areas and levels of resilience Identify required resources and timing Listen to the stories and the science

- Todays talk is on an ecological burn undertaken at Pierre Close, Mount Colah Hornsby Shire Local Government Area North of Sydney A small urban reserve of just under 8 ha Natural area of: 11980m squ just over 1 ha Burn area of: 5327m sq - just over ½ ha
- DESCRIBE The reserve Bounded by single story residential dwellings The main Northern Rail corridor to the west Mount Colah Public School to the south GEOLOGY/ SOILS Reserve lies on Sydney Sandstone SOIL Sandy loam overlying bleached and stony sandy clay loams SLOPE East facing Moderate slope – approx. 10 degrees East facing aspect CONNECTIVITY/ CONTEXT Berowra Valley Regional Park is within 1km to the west and Ku-ring-gai Chase National Park is less than 1km to the east Vegetation cover extends in a very narrow strip to the north along the rail corridor which leads to a long corridor of vegetation running parallel to the western side of the M1. Sydney Sandstone Woodland Structure variable and incorporates Woodland/ Low woodland. Canopy was dominated by Allocasuarina littoralis (Back She Oak) with uncommon under canopy tree species of Angophora costata and Eucalyptus haemastoma. Also occurring in a mature form were Acacia elata (mountain Cedar Wattle).
- A REQUEST FROM BUSHCARE AN EXAMINATION Sparse midstory stratum 2007 report by Total Earth Care noted the foliage projective cover as 20% in the midstory and 5% in the understory. Understory dominated by juvenile Pitosporum undulatum and Pittosporum revolumtum. Shrubs such as Kunzea ambigua (tick bush) also common. Ground cover sparse cover native grasses such as Microlaena stipoides and Dianelle Caerulea. A senescing plant community Dominated by Allocasuarina littoralis Few ground covers and Little vertical or horizontal diversity Weedy vines on edges Changing in the absence of fire Original request was for the entire reserve Site inspection identified the priority was the north section of the reserve – as it was senescing and had no- very limited fire history The site also contatied sig, stand of Allocasuarina – Identified that the site south of the school had good resilience Site checks identified that north of the aprth need ed a burn Records showed xxx years since burning. Within 500m and 1km 2 reserves consisting primarily of Allocasuarina – exiting habitat for Glossy Black Cockatoos On Ground CHECK Information feeding into the decision Information check – no historical pics/ info Acknowledgements Map is from Bushcare 2010. Pics are from Bushcare Michael Cruikshank
- ENVIRONMENTAL ASSESSMENT Making sure the burn would work from 1) Ecological perspective 2) Fuel perspective LISTING THE BURN On the Hornsby Ku-ring-gai Bushfire Management Committee Works Program SITE PREPARATON Duff on the ground –containing moisture – steam roots, smoulder and not burn Felling casuarinas – only fell a small are as concerned about the results Added benefit of multiplying the heat intensity and variety of post burn environments The DOOM CONTINUES A comment from a community contact Pile burns have been done before and they did not work ENVIRONMENTAL ASSESSMENT ITS ALL DOOMED A comment from a community contact SUCCESS REQUIRED Right fuel profile Right weather conditions Safe conduct Hot burn Constraints The approx. 12 days a year prescription wise able to burn Add School hours – no burning – School holidays Northern trail line to Gosford – wait for line to be closed for works Not allowed to access the site – waiting for the line to be closed for works
- State rail – Supervisor on site in case of fire escape 40,000 LPG Gas cylinder on site at the school immediately adjacent to the reserve Childcare centre – pumper in attendance Weather Conditions Date: Time: Temp: Wind speed: Humidity: Fuel conditions: Right Weather:
- Immediately Issues Weed control Follow up Access control
- Results
- Species increase Fuel increase NOTE Resourcing requirements were Preburn: Liaisons and negotiations; environmental assessments; Tree felling ($1500) Burn Fire and rescue: xxx tankers, xxx staff Post burn Bush regeneration contractors approx. $3000 2 staff x 21 hrous (3 days)
