Hope for regent honeyeater with signs of booming blossoms after NSW rain and floods
There have been observations of a mass eucalypt budding event in the wake of the flooding across the Mid North Coast and Hunter regions.
Mick Roderick, Birdlife Australia's regent honeyeater recovery adviser, said he had seen various eucalypt species thriving in the Hunter after their prolonged soaking during April and May.
He said as the different species flowered the blossom season could last throughout the next year at least.
It would provide food for the regent honeyeater, a species which has dropped to around 300 wild birds.
"To know that so many trees will be flowering from a breeding season, right through summer and winter … is significant for a critically endangered species that relies almost exclusively on nectar," Mr Roderick said.
"It provides the regent honeyeaters that are left with an opportunity to take advantage of those conditions and hopefully successfully breed.
Mr Roderick said Birdlife Australia had recent evidence of hundreds of honeyeaters of various species and lorikeets feeding on the coast where swamp mahogany trees were flowering, while white box was flowering on the western slopes.
He said many other eucalypts had been observed putting on buds in preparation for flowering.
"The exciting thing is we seem to now have a mass budding of certain eucalypts, certainly in the Hunter Valley, and most of the buds have appeared after the really heavy rain," Mr Roderick said.
"So we have red gums, ironbarks, grey gums, and then spotted gums to follow all these spring flowering gums.
Mr Roderick said eucalypt blossoms typically dropped during drier years and it was the most promising blossom season in the region since heavy rainfall in 2021/'22.
"We're going to have two exceptional seasons within four years of each other, which is pretty incredible," he said.
Dean Nicolle, a consultant botanist and ecologist specialising in eucalypts, said there were more than 800 different eucalypt species throughout Australia and that certain species grew strongly in the wake of prolonged rainfall.
"Some species are very tolerant of flooding and waterlogged soils and are much more drought sensitive, while other species are much more drought tolerant," he said.
"The species described [in the Hunter], like spotted gums and ironbarks, are generally species of hillsides and ranges.
"They would be responding to increased moisture in the soil, so conditions are good for growing.
"They can take up as much water as they want, grow lots of leaves and then flower heavily."
The budding eucalypts are also a welcome sight for apiarists, including Hunter Valley-based Colin Wilson who has been a commercial beekeeper for about 45 years.
"In the Hunter Valley at the moment there's ironbark species putting buds on, spotted gum trees, grey gum trees, so there's a fair range of trees which will all flower at different stages," he said.
"The last few years they have been below average in the amount of flowering and nectar and it's looking a lot more hopeful for the next 12 months.
"Trees bud sometimes six months or more in advance before they flower. As a beekeeper you then know there'll be some honeyflows."
Mr Wilson had to euthanase bees when varroa mite was detected in the region several years ago.
"A lot of people around here have suffered quite a lot financially over the last few years because hives were euthanased," he said.
"We brought bees back again when we were allowed to and have a growing process of expanding bee numbers.
"When you can see a bit of a light at the end of the tunnel it does give you a bit of hope."

Fifteen rivers are at risk of flooding in NSW as saturated catchments receive downpour
Upgraded flood warnings are in place across NSW as the east coast braces for another day of relentless rain. Northern NSW is set for a deluge on Thursday, with 15 already saturated catchments in the region now under flood watch. The Peel River near Tamworth is tipped to reach minor flood levels overnight into Friday, while parts of the Namoi River along the North West Slopes are set to reach major flood levels of more than seven metres. Dangerous river conditions are already threatening residents, with a search under way for two missing people who crashed into the Macdonald River in the Hunter Region just before midnight on Wednesday. While the Macdonald River was not flooding at the time, the incident is being treated as a flood rescue by NSW SES due to the extreme rainfall impacting the region. 'We'd like to remind people that flash flooding can occur suddenly and without warning,' NSW SES Assistant Commissioner Colin Malone said. 'Please never, under any circumstance, drive through floodwaters. If you come across a flooded road, turn around and find another way.' Isolated falls cracked triple digits across the state overnight. In the 21 hours to 6am, the highest totals were 115mm at Port Macquarie, 113mm at the Maria River and 111mm at Lake Cathie, all on the Mid North Coast. 'Rivers across northeast NSW have responded quickly to the rainfall seen overnight,' Bureau of Meteorology senior meteorologist Helen Reid said. 'As of 6am on Thursday morning, a flood watch for minor to moderate flooding remains current for much of northeast NSW, including the North West Slopes, Mid North Coast and into the Hunter.' Rainfall totals for Thursday are likely to be between 40 to 80mm across much of Australia's east coast, from the Gold Coast in Queensland to the Illawarra in NSW. The drenching is forecast to finally ease from Friday afternoon, as a coastal low pressure trough moves away from the east coast, drawing moisture and rainfall offshore. 'However, we are likely to see the impacts of any flooding that develops continuing into next week,' Ms Reid said.

High rainfall totals and thunderstorms forecast for south-east Queensland
A low-pressure system trough is expected to deepen today, bringing the possibility of high rainfall and thunderstorms in south-east Queensland. Forecasters said the Gold Coast, Brisbane, Sunshine Coast and Darling Downs should expect more dreary conditions. Morgan Pumpa from the Bureau of Meteorology (BOM) said the focus would be on the border ranges from Goondiwindi across to the Gold Coast. The chance of the heaviest rainfall and thunderstorms is on the Gold Coast, but Brisbane will experience shower and thunderstorm activity with rainfall between 7 and 40 millimetres likely. "It will depend on thunderstorm activity, but at Coolangatta we have a forecast of 15–70mm on Thursday alone, and 3–30mm on Friday," Ms Pumpa said. Areas around the Darling Downs and Granite Belt can also expect widespread rain, which could lead to river rises. "It's really important for people living in these areas to look at the radar and keep an eye on the shower activity, and stay up to date with all the latest warnings," Ms Pumpa said. "There's probably more of a concern over the border in New South Wales for flooding conditions, but for Queensland, we're focused on severe thunderstorm warnings." Senior meteorologist Angus Hines said the wet conditions were unusual. "Some places have already had above 50mm of rain, and when we add in what we're expecting during Thursday, we could see some spots over 100mm for the week, which is quite a wet week at any time of year, but particularly at this time of year." Last year, the BOM recorded 71mm of rain through August for parts of the south-east. Beyond the southern towns, Mr Hines said cloudy skies and some spotty showers were forecast from the Wide Bay to Mackay through Thursday. "You might see a small amount of rainfall in those districts without it really tipping the rain gauges over more than about one or two millimetres," he said. "We have a fine, clear and sunny day across central and western parts of Queensland." He said temperatures would be relatively cool across the south of the state and warm in the north. "It's been a cold couple of days around Brisbane [and] it's going to be on the cooler side of average again," Mr Hines said. "Western and northern parts of the state are a fair bit warmer with those clearer skies and sunshine, and in fact a lot of places in northern Queensland tending to be one or two degrees warmer than average for this time of year." Mr Hines said the rain would clear during Friday. "It could be a wet start to the day, but by about lunchtime it looks like most of that rain has gone," he said. "The rest of the state is heading for a pretty dry day." He said a sunny weekend was on the cards for most of the state. "A couple of showers are possible around the Capricornia and the Central Coast, but really minimal rainfall forecast anywhere across Queensland this weekend," Mr Hines said. "We're expecting to see far more sunshine than cloud cover."

Small hive beetle decimates bee populations on mid north coast before spring
Despite the cooler weather, Chris Tejcek's small-scale permaculture farm is usually buzzing with bees throughout winter. But this year, he has struggled to find even one at his property at Beechwood, on the New South Wales mid north coast. "We're in a quieter period … but the way that our property is set up, we've got a lot of fruit trees and Australian natives, most of which are still in full bloom … we've normally got bees everywhere," he said. All five of Mr Tejcek's hives were abandoned after they were infested with small hive beetle, an introduced insect that feeds on pollen, honey and dead bees, leaving behind a slimy residue that drives out bees. In July, he burnt the infested frames to help prevent the beetle from spreading further. "That's a really hard thing to do, to just stand there when you've [put] an incredible amount of work in establishing and building colonies," he said. Small hive beetle has been in Australia since 2002, but Mr Tejcek said this year was the worst he had seen. The situation on Mr Tejcek's property has been mirrored across the NSW mid north coast, where the combination of varroa mite and repeated floods has left hives vulnerable. Hastings Valley Amateur Beekeepers Association biosecurity officer Leon Carle said the conditions had created a "perfect storm". "The bees usually manage [the beetles] and lock them up in what we call beetle jails … they force the beetles in there," Mr Carle said. "But with the varroa, it weakens them … so the beetle gets out [and] the bees either die with it or they abscond." Of 22 club members surveyed, 73 per cent of their combined 150 hives had been lost this year, to floods, varroa mite or small hive beetle. Technical specialist for honey bees at the NSW Department of Primary Industries and Regional Development Elizabeth Frost said beekeepers north of the NSW Central Coast were reporting unseasonably high numbers of small hive beetle. "We think that … elevated numbers are a result of beetles being able to reproduce in these hives that are dying in feral locations and also potentially neglected hives or any hives that have died in a flooding event," she said. Ms Frost was concerned small hive beetle populations could explode further as the weather warmed up, with one brood frame able to yield about 6,000 larvae. "Bee reproduction increases, all manner of insect and arthropod reproduction increases so beetles, varroa, we have to keep all these things in mind … as the season warms up." She said there were steps beekeepers could take to protect their hives. "Having really strong, healthy bee colonies, having young and productive queens, fixing up any colonies that the queen dies in and keeping a tight colony [will help]," she said. "Worst comes to worst, there are mechanical and chemical treatment methods … that work really well at killing small hive beetle." Ms Frost was confident increased beetle numbers could be mitigated if beekeepers across Australia remained diligent with varroa mite treatments, with high levels of varroa found in areas reporting major losses from small hive beetle. However, Mr Carle said varroa mite infestations in feral hives complicated treatment options, making it hard to maintain strong hives. "You can treat for varroa and have very low numbers but within two weeks you've got extraordinary numbers of varroa again," he said. "Simply because they've been out robbing out the hives in the bush … so all the varroa there waiting, jump on the bees [and] come back to your hive."
