Heavy feeding marks on a Sydney sandstone bloodwood — likely from a sugar glider.
These horizontal scar bands are classic sap-feeding traces. Sugar gliders cut through the outer bark to access kino-rich exudates and sap flows beneath the surface. Over time, repeated feeding produces distinct circumferential scoring like this.
Sydney Sandstone Ridgetop Vegetation
Sydney’s sandstone ridgetops support some of the most distinctive bushfire-adapted landscapes in the Basin. Shallow skeletal soils over Hawkesbury Sandstone limit moisture and nutrients, producing open eucalypt woodland with a strong shrub and grasstree (Xanthorrhoea) understorey and scattered ferns in protected pockets
Non-combustible cladding isn’t just an architectural choice in bushfire-prone areas — it’s a risk decision. External wall systems are one of the first elements exposed to radiant heat, ember attack and flame contact. When the wrong materials are used, the building envelope can become part of the problem instead of part of the protection strategy. Bushfire protection is rarely achieved through a single measure. It comes from decisions that work together — siting, landscaping, access, water supply and construction
Basal fire scar that has progressively developed into a hollow through repeated fire exposure and decay. Ecologically, these hollows are extremely valuable: • habitat for mammals • nesting for birds • refuge for reptiles • invertebrate microclimate buffering
Banksia spinulosa (Hairpin Banksia) is widely distributed across eastern Australia and commonly occurs within woodland, heathland and open forest environments From a bushfire ecology perspective, Banksia spinulosa is primarily a resprouting species. Following fire, regeneration typically occurs from: • lignotubers at the base of the plant, and • epicormic shoots along surviving stems
rather than relying exclusively on canopy-stored seed release.

Fire trails are more than just tracks through the bush.
Clear, well-marked fire trails play an important role in bushfire preparedness by:
• Helping emergency crews navigate quickly and safely
• Reducing uncertainty during high-pressure situations
• Supporting coordinated response and land management
• Providing clarity for maintenance, access and use
• Improving safety for those who rely on them
When visibility is reduced and conditions are changing, clear wayfinding matters.
Trail names, identifiers and location information aren’t about red tape —
they’re about making the right decisions, faster.
This is what a well-managed riparian APZ looks like.
✔️ Grass maintained at low fuel loads
✔️ Managed vegetation structure
✔️ Separation to unmanaged bushland
✔️ Retained ecological values
✔️ Integrated into urban design
This isn’t over-clearing.
It isn’t under-managing.
It’s proportionate bushfire planning.
A riparian corridor can provide ecological function, stormwater treatment and visual amenity — while still achieving defendable space outcomes.
Bushfire protection doesn’t mean stripping landscapes bare.
It means managing them intelligently.
This is how you balance risk, ecology and liveability.

A simple roadside sign, but a serious reminder.
In fire-prone landscapes, everyday actions can have major consequences.
Awareness is the first layer of bushfire risk management.
Jarrah forests in south-west WA have evolved with fire for tens of thousands of years. Thick bark protects mature trees, epicormic buds drive rapid recovery, and many understorey species rely on heat and smoke to regenerate.
When fire occurs at the right intensity and frequency, it:
• Reduces long-term fuel loads
• Resets forest structure
• Supports biodiversity
• Lowers the risk of severe, landscape-scale bushfires
Understanding fire adaptation is critical to good land-use planning, hazard reduction, and proportionate bushfire design.
At Blackash, we work with fire ecology — not against it — to deliver safer, more resilient outcomes grounded in science and local context.
