More than 100 prominent individuals throughout Canadian society, along with a handful of international supporters, urged British Columbia Premier John Horgan on Friday to fulfill his campaign pledge to immediately protect the region's imperiled old-growth forests, which continue to be logged despite scientific warnings against further destruction.

Do Forests Grow Better With Our Help or Without?

But a new study shows that the potential for natural forest regrowth to absorb carbon from the atmosphere and fight climate change is far greater than has previously been estimated. Story here.

Bushfires damaged Australian rainforest that is home to Earth's only living specimens of ancient species

Photo by Naught101 Recent wildfires in Australia torched more than 48,000 square miles of land (for context, more than 40 Riding Mountain National Parks). The fires impacted ecologically sensitive regions, including an area called the Gondwana Rainforests of Australia World Heritage Site. This region contains a vast concentration of living plants with fossil records from tens of millions of years ago, according to Peter Wilf. Story here.

At a remote site where the world’s largest rainforest abuts land cleared for big agriculture, Brazilian and American scientists are keeping watch for a critical tipping point – the time when the Amazon ceases to be a carbon sink and turns into a source of carbon emissions.

Remote lakes in New Brunswick, Canada, remain dangerously polluted, half-a-century after being drenched with the insecticide, DDT, says study.

Image
It's no secret that the now-infamous bug-killer, DDT , persists stubbornly in the environment. Still, what scientists found in lake sediments they recently analyzed in the Atlantic province, 50 years after it was last used there, shocked them. The sediment in all five lakes they tested (representing numerous watersheds), were laced with DDT at levels up to 450 times beyond what would be considered safe for key aquatic species and even entire food webs. by Larry Powell A plane sprays DDT on bud worms in Oregon, 1955.  Photo by Forest Health Protection. In some ways, it was like a real war. In the early fifties, governments and the forest industry teamed up in New Brunswick to launch a massive aerial assault against spruce bud worms.  The pests had probably been eating their way through conifer stands in eastern Canada and the U.S. for thousands of years. But now, they were causing hundreds of millions of dollars of damage yearly to forests of mostly spruce a

Soil communities threatened by destruction, instability of Amazon forests

Image
Science Daily  In this image, intact forest is deep green, while cleared areas are tan (bare ground) or light green (crops, pasture, or occasionally, second-growth forest). The fish-bone pattern of small clearings along new roads is the beginning of one of the common deforestation trajectories in the Amazon.  A NASA photo. The clearing and subsequent instability of Amazonian forests are among the greatest threats to tropical biodiversity conservation today.  Story here.

The World Lost an Area of Primary Rainforest Last Year, the Size of Ten Riding Mountain National Parks in Manitoba!

Image
WORLD RESOURCES INSTITUTE Manitoba's Riding Mtn. Park. The tropics lost 12 million hectares of tree cover in 2018, the fourth-highest annual loss since record-keeping began in 2001. Of greatest concern is the disappearance of 3.6 million hectares of primary rainforest, an area the size of Belgium (ten Riding Mountain Parks). The figures come from updated data from the University of Maryland, released today on Global Forest Watch. More here.

By User Kelberul on de.wikipedia  A growing body of evidence indicates that the continuing destruction of tropical forests is disrupting the movement of water in the atmosphere, causing major shifts in precipitation that could lead to drought in key agricultural areas in China, India, and the U.S. Midwest.

Vancouver Island rainforest stands are becoming as rare as white rhinos

The Province Part of the remaining stand of rainforest on Vancouver Island. Photo by Jason Holinger. For millennia, Vancouver Island was mostly covered by spectacular, globally rare ancient rainforest. Many trees were 1,000 years old or older. Indigenous peoples co-existed with the rainforest using many of its plants and animals without destroying it. Shortly after the arrival of Europeans, logging began in earnest. In less than 100 years, the majority of the ancient trees have been logged. Story here.
