Last October, I received a call from a property owner in the Scenic Rim, just outside of Beaudesert, who was facing a genuine crisis. They had ten acres of spectacular country bordering a national park, but half of it was a near-vertical sandstone escarpment that had become a monoculture of Mother of Millions (Bryophyllum delagoense).
The owner was distraught because they had recently lost two head of cattle. While many people think of Mother of Millions as a "pretty" succulent often found in heritage gardens, it is a Category 3 restricted matter under the Biosecurity Act 2014. It contains cardiac glycosides that cause heart failure in stock. On this property, the weed had spent five years creeping down the gullies and across the steep faces where no tractor or slasher dared to go.
This case study breaks down why this specific plant is such a nightmare for South East Queensland landholders and how we used specialised steep terrain clearing techniques to turn the tide for the local ecosystem.
The Challenge: A Vertical Minefield of Toxicity
When I first walked the boundary, the sheer scale of the infestation was daunting. Mother of Millions is an escaped ornamental plant from Madagascar, and it thrives in our SEQ climate. It doesn't just grow; it colonises. Each leaf produces tiny plantlets along its edges that drop off and take root instantly.
The biggest issue on this Scenic Rim site was the terrain. The infestation was concentrated on a 40 to 50-degree slope littered with loose rock and fallen timber. Standard machinery would have rolled instantly. The property was also choked with Lantana and patches of Wild Tobacco, which acted as a nursery for the succulent, protecting it from the wind and allowing it to carpet the ground entirely.
The owner had tried hand-pulling, but they quickly realised the futility. If you leave a single leaf or one of those tiny plantlets on the ground, the infestation resets within a single season. On a cliff face, hand-pulling is also a safety nightmare. We needed a solution that would pulverise the biomass and allow the soil to breathe again.
Why Forestry Mulching Beats Spraying Alone
In my opinion, relying solely on chemical spraying for a massive Mother of Millions outbreak is a mistake. If you spray a dense carpet of these succulents, you end up with a huge mass of rotting, slimy organic matter that hangs around for months. This prevents native seeds in the seed bank from germinating and often protects the smaller plantlets underneath from the herbicide.
We decided to lead with forestry mulching. By using our high-flow mulching heads on a machine designed for extreme inclines, we could physically masticate the plant. This process does three things: it destroys the physical structure of the succulent, it incorporates it into a fine mulch that begins to break down, and it exposes the bare earth to sunlight.
I’ll be honest: mulching Mother of Millions is messy work. The plants are full of moisture, and they turn into a bit of a slurry. However, this is far more effective than leaving them standing. Once we cleared the Other Scrub/Weeds and the thickest patches of the succulent, we could see the actual contour of the land for the first time in a decade.
Restoring the Habitat for Native Wildlife
One of the main goals for this project wasn't just clearing the way for cattle; it was about wildlife corridors. The Scenic Rim is a biodiversity hotspot. While the Mother of Millions was there, nothing else could grow. There was no ground cover for lizards, no native grasses for wallabies, and the toxic nature of the plant meant the area was a dead zone for local fauna.
After we finished the initial weed removal phase, the change in the environment was almost immediate. By removing the canopy of Privet and the thick mats of Mother of Millions, we allowed the dormant native seeds to see the sun.
Within six weeks of the first mulch, and following a decent spring rain, we started seeing native Kangaroo Grass and Blue Grass popping up through the mulch. The mulch acts as a protective blanket, holding moisture in the soil and preventing topsoil erosion on those steep 45-degree sections. For the first time in years, the property owner reported seeing wallabies returning to that section of the escarpment to feed on the emerging native shoots.
Dealing with the "Resurrection" Factor
If an operator tells you they can get rid of Mother of Millions in a single pass with 100% success, they are dreaming. This plant is a survivor. Because it stores so much water and can regrow from the smallest fragment, follow-up is mandatory.
On this property, we performed the heavy lifting with the mulcher over three days. We cleared the gullies, the steep ridges, and the flat paddocks that were slated for paddock reclamation. However, we were very clear with the client: you must watch this like a hawk for the next 12 to 18 months.
The beauty of the mulching approach is that it makes follow-up incredibly easy. Instead of fighting through a shoulder-high wall of weeds, the owner could walk the cleared tracks and spot-spray any tiny green shoots that emerged from the mulch. We also created a series of fire breaks during the process, which gave the owner vehicle access to parts of the ridge they hadn't visited in years. This access is the secret to long-term weed management. If you can't get to the weed, you can't kill the weed.
The Result: From Death Trap to Productive Land
The transformation of this Scenic Rim property was one of the most satisfying projects we've handled recently. We moved through about four acres of the heaviest infestation on the steepest ground.
Three months after the job was completed, the "dead zone" had vanished. The hillsides were green, but it was the right kind of green. The toxic succulent was gone, replaced by native grasses and a few pioneered wattles. The cattle were back in the paddock, and the risk of poisoning was effectively eliminated.
We did hit a few snags. The sandstone was particularly brittle in one gully, which meant we had to adjust our approach to ensure we didn't cause unnecessary soil disturbance. Proper land clearing isn't just about smashing everything in sight; it's about knowing when to be aggressive and when to use a lighter touch with the machine's hydraulics.
Practical Advice for SEQ Property Owners
If you are dealing with Mother of Millions on your property, whether you're in the Gold Coast Hinterland, Logan, or Ipswich, here is my professional stance:
- Don't ignore the slopes: Weeds love gullies because they are harder for you to reach. This is where the seed bank builds up.
- Timing matters: Try to tackle Mother of Millions before it flowers (typically in winter). Once those orange/red bells appear, the plant is about to drop thousands more seeds.
- Mulch over pushing: Don't just push the plants into a pile with a dozer. You'll just end up with a massive, concentrated pile of Mother of Millions that will grow into a mountain. Mulching destroys the plant's ability to store energy.
- Access is everything: Use the clearing process to create permanent access tracks. If you can't get a UTV or a spray pack to the site easily, the weeds will eventually win the war of attrition.
Managing invasive species on South East Queensland’s steep terrain requires the right gear and a bit of "mountain goat" spirit. Mother of Millions is a formidable opponent, but with the right mechanical intervention, you can reclaim your land and protect the local environment.
