Firecraft were left in awe this week and totally humbled by the stark contrast of the ancient forest greenery against the scar on Thornton Peak from the slump landslide. A major geological event that occurred in the Daintree rainforest in July 2018 after significant rainfall.
Some may consider it an environmental disaster having an impact on our oldest rainforest…… or does it have important ecological function similar to a volcano?? Certainly sparks thoughts of what will grow there and inhabit it in our lifetime before it develops its pre-landslide complexity long into the future again.
I recently had a question posed to me – “If we accept foreign people into the country in every State, why is it a problem letting foreign plants in?”
I found this question really surprising at first…..then it occurred to me that perhaps the extent of our weed problem and the importance of protecting Australia may be unnoticed.
Weeds or invasive plants are arguably one of our biggest threats to our ecosystems and biodiversity, and also to farming. Prohibiting the introductionof plants and the effort that goes into prevention of spread and eradication of weeds is an annual multi-billion-dollar effort.
Take Rubbervine (Cryptostegia grandiflora) for a North Qld and Cape York example. Introduced in 1875 from Madagascar as an ornamental plant for mining camps due to its adaptation to harsh conditions, lush foliage and pretty flowers, it is now a Weed of National Significance (DAF, 2019). Considered one of the worst weeds in the country it is toxic to cattle, takes over our riparian vegetation along our river systems, and degrades important habitat needed for wildlife survival.
This infestation being managed by Firecraft is on the Desailly Range south of the road to Cooktown. The Rubbervine is estimated at 25m high in places, blanketing and killing native trees and shrubs, and creeping its way rapidly up to the road.
The Mount Carbine Tableland open forest has been transformed in the past few weeks from a dry parched landscape to a picture of lush new growth after the monsoonal rain. Species such as the perennial Native Rosella (Abelmoschus moschatus subsp. tuberosus) lies dormant in the dry seasonal and then emerges from its tuber during the wet season. The bush-tucker plant only flowers for one day. This paddock near Mount Molloy has been subjected to a hot late-season fire that has removed the weedy understory and now is a canvas of iridescent green new growth with splashes of the Rosella’s watermelon-pink hibiscus flowers.
This Great Bowerbird (Chlamydera nuchalis) bower scattered with snail shells, gravel and various colourful treasures was admired today by Firecraft Crew in the Mt Garnet area.
Bowerbirds have always been recognised for their construction abilities, pedantic arrangement of bowers and particular adornments they choose to scatter around the cleared area of the bower to attract females.
But is the cleared area only to make the bower standout?? Some researchers believe these species of bowerbird may have adapted to fire prone environments by deliberately clearing a ‘firebreak’ around their bower to protect it from wildfire…..
It is a well discussed topic that the echidna is a heterothermic mammal – meaning they can regulate their temperature as an adaptation for survival. They are the oldest mammal – a monotreme, having survived the times. It is believed the echidna can drop its body temperature during a wildfire and this is a mechanism that allows it to survive for several reasons.This one was spotted by Firecraft on a hike recently up Macalister Range behind Panguna Valley.
Storm burning or wet season burning can be difficult to execute due to the restrictions that often come with being prepared to burn within a short timeframe dictated by weather and on-ground conditions. However, there are many benefits both ecological and economic of burning outside of the typical fire season. Read on to learn more.
A cost-effective tool for weed management
Burning after the first wet season rains or before first storms can be a cost-effective tool for weed management. “Extending” the fire season to include a wet season timing, often promotes positive ecosystem responses such as increasing diversity and broadening the fire footprint over a property to ensure the same areas are not burnt every season thus reducing fire frequency.
Storm burns at Mitchellvale
Firecraft Environmental carried out storm burns for pasture management and weed management at ‘Mitchellvale’ pastoral property north of Mount Molloy on the Mount Carbine Tableland in the last week of November. The objectives were to reduce woody weeds that had emerged from recent rainfall and promote green-pick for stock.
When the opportunity arises to burn just after the first storms to suppress freshly germinated weed seedlings and conditions are favourable the benefits are evident. The balance is having enough hayed-off grass or fuel with 1-2 years growth amongst the weeds that will carry a fire under humid conditions, hot enough to kill the weed seedlings. The anticipated storm or rainfall that follows promotes a flourish of new growth in pasture or native grasses.
