2 million hectares of Queensland forest destroyed

 From The Guardian

More than 2m hectares (4.94m acres) of bushland in Queensland that included large swathes of possible koala habitat has been cleared over a five-year period, new analysis shows.

The research, commissioned by Greenpeace and conducted by the University of Queensland academic Martin Taylor, found almost all land clearing that occurred in the state between 2016 and 2021 was in areas where threatened species habitat was “likely to occur”.

Almost two-thirds of the cleared area, or 1.3m hectares, was marked by the Queensland government as “category x”, meaning it was exempt from state vegetation laws that regulate land clearing. Some 500,000 hectares of that land was koala habitat, the report said.

Taylor, an adjunct professor at the University of Queensland and former WWF-Australia conservation scientist, conducted the analysis by comparing state government land clearing data to federally mapped areas of environmental significance.

The majority of recorded land clearing occurred in regrowth forest that was more than 15 years old, which Taylor said made it capable of providing rich habitat for native animals.

“Industry voices like to say this is just controlling knee-high regrowth, so it’s just vegetation management,” he said. “[But] a 15-year-old eucalypt forest can be at least 10 to 15 metres high – they are forests.”

Taylor said that while laws in Queensland allow for regrowth forests to be reclassified as remnant once they mature, the requirements to do so are unclear.

“A lot of regrowth 15 years and older could have already become what they define as remnant, making it more difficult to clear,” he said.

Gemma Plesman, a senior campaigner at Greenpeace Australia Pacific, said the report documented deforestation on a “frightening” scale. She said the state’s annual statewide land cover and tree study (Slats) shows land clearing was driven by beef production.

According to the beef industry, more than 10m cattle graze on Queensland pastures, making it the biggest beef producing state in the country.

“Fast food chains and retailers should be aware that the beef they are selling could come from properties that have bulldozed koala habitat with no government oversight,” Plesman said.

Plesman said environmental law reforms being developed by the federal government needed to address concerns around deforestation in Queensland to be effective.

“This shocking data should be a wake-up call,” she said. “They must address what has made Australia a global hotspot for deforestation.”

The Wilderness Society Queensland campaign manager, Hannah Schuch, said deforestation in Queensland was driving biodiversity loss.

“It’s having an impact on iconic native species like the koala, the greater glider, the red goshawk, it’s tearing down their homes and pushing them towards extinction,” she said.

“We know that erosion and sediment runoff from deforestation is another threat to the already at-risk Great Barrier Reef,” she said.

A spokesperson for the federal environment minister, Tanya Plibersek, said the government was in the consultation process to develop new national environment laws. However, three organisations familiar with the draft laws say they would continue to allow widespread deforestation.

Michael Guerin, the chief executive of Queensland farming body AgForce, questioned the accuracy of the Slats data which was used in Taylor’s analysis. He said deforestation rates were overstated. [Of course he did]

He suggested there should be an on-the-ground survey to confirm deforestation rates. [which is much more expensive and not necessarily more accurate. In fact aerial surveys often miss small areas of clearing, meaning the real total could be higher.]

“Let’s come out and ground truth it,” Guerin said. “Let’s get out on the landscape and spend the money and time so we’re confident about what’s happening. The industry and community is up for that.” [yeah, right]

Australia's "decline" in emissions is solely due to LULUCF (Land Use, Land-Use Change and Forestry)    There have already been questions and accusations that the data are dodgy.  One claim is that partially cleared land is not picked up by the satellites; only fully cleared land is.  This latest analysis simply adds to the evidence.  

Oh, and I beg you: stop eating beef.  

Trees bring rain

My mother used to say that, and I didn't believe her.  Arrogant pup!  Here's an excerpt from a deeply depressing Guardian article about land clearing in Australia which explains how the process works:

Prof Clive McAlpine from University of Queensland explains that not only does land clearing release greenhouse gases into the atmosphere, it also has an effect on climate, well beyond the emissions.

“It causes warming locally, regionally and even globally, and it changes rainfall by altering the circulation of heat and moisture,” he says.

“Trees evaporate more water than any other vegetation type – up to 10 times more than crops and pastures. This is because trees have root systems that can access moisture deep within the soil.”

The increased evaporation and rough surface of trees create moist, turbulent layers in the lower atmosphere, he says. “This reduces temperatures and contributes to cloud formation and increased rainfall. The increased rainfall then provides more moisture to soils and vegetation.

“The clearing of deep-rooted native vegetation for shallow-rooted crops and pastures diminishes this process, resulting in a warmer and drier climate.”

McAlpine argues that we should be replanting in the north-west of NSW and south-west Queensland to achieve a tree density of 40% to stabilise the local climate. Grazing would still be possible underneath the tree cover.

This is why the centre of continents at the equator have high precipitation.  At the coasts, the rain comes from moist air from the sea.  But it falls on rain forests, and the trees transpire water vapour into the air.  In the tropics, an acre of rain forest puts more water vapour into the air than an acre of sea.  This water vapour then falls on forests further inland and the process is repeated.  So even in the heart of the continent, there is rain and rain forest, and the two go together.  Which is why land clearing can create a desert. 

As a species, we seem bent on destroying our world.
