An extraordinary insect preserved in amber is opening our ears to a world of communication beyond our hearing. New research on an extinct katydid in the Natural History Museum’s collection reveals that katydids have been using ultrasounds for millions of years to try and avoid predators hearing them.

Bretton Clough, Derbyshire: A huge window of blue opens above us, and the slopes catch fire with coppery brackenBretton Clough Farms are ruins now, a heap of stones topped with shrubby trees. They occupy a rise above a stream that after recent rain was crashing through its steep-sided valley. It is raining as we arrive, slopping down the hill on an old cart track, but then a huge window of blue opens from the south-west and the slopes around us catch fire, with coppery bracken and yellowing oak leaves.There were once two farmhouses here, semi-detached, built most likely in the 17th century. They’ve had various names through time, Bretton Twin Farms being self-explanatory. Another was Fairest Clough, sometimes Fairies Clough – just right for a place whose harmonious flow and tangled woodland has magic in it, especially on such a day of sunshine and showers as this.

Government sets up national holiday in hope of planting 15bn trees by 2032 to tackle climate crisis and deforestationGeoffrey Mosoku and his two daughters have been digging a seedling deep into the ground of the Ngong forest in Kenya’s capital, Nairobi.“It can become part of Kenyan culture to do environmental work,” said Mosoku, as he and his daughters tapped the tree into place in the natural forest a few kilometres from the city centre. The trio were one of hundreds of people who showed up at the forest on Monday to plant saplings for Kenya’s first national tree planting holiday despite heavy morning rains. Continue reading…

Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.

New study estimates that natural forest recovery could capture approximately 226 Gigatonnes (Gt) of carbon, but only if we also reduce greenhouse gas emissions. Achieving these results requires community-driven efforts to conserve and restore biodiversity. In brief: Forests have the potential to capture 226 Gigatonnes (Gt) of carbon in areas where they would naturally exist. This forest potential can only be achieved alongside emissions cuts. Sixty-one percent of the forest potential can be achieved by protecting existing forests and allowing them to regrow to maturity. Thirty-nine percent can be achieved by reconnecting fragmented landscapes through community-driven ecosystem restoration and management. A natural diversity of species is needed to maximize the forest carbon potential.

Dunblane, Stirling: We must never take for granted that we can visit wild, splendid places like this wooded gorge, in all its November bestFew soles trample this upper glen and the dwindling track as it skirts the Wharry Burn’s gorge. Those that do are rewarded with a ravine of surprising drama. At the head of the chasm, where fallen trees and gravel bars accumulate, the burn is placid. But here, at the lip of the first cascade, the water squeezes between two sandstone boulders, accelerating into a racing white flume, hissing with second thoughts.I leap the gap between the boulders, to where the only trails belong to the deer; to where the only prints are cloven. They trace secretive routes, brushing through bracken fronds and around the silent trunks of the broadleaved woodland – beech, elm, ash and birch. Continue reading…

High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.

Such a move would greatly increase access opportunities throughout England’s countryside, writes Marion ShoardThe argument for a universal right of access is compelling (Letters, 5 November), but if Keir Starmer is reluctant to go that far, he could opt instead to build on the Blair government’s Countryside and Rights of Way Act 2000 by granting a right to access to woodland.Such a move would greatly increase access opportunities throughout England’s countryside, except in extensive arable areas. It would be cheaper to implement than the original 2000 act, as the complex botanical work and mapping required for terrain such as chalk downland would not be necessary. Nor would there be any need for signposting to identify such access land: woods are already shown on Ordnance Survey maps and we can all identify one. Continue reading…

Plant species are distributed in their preferred climatic zones, and plants growing at the edge of their natural distribution range often exhibit poor growth when relocated to a different environment. This phenomenon has been attributed to two factors: 1) the environment at the edge of the distribution is extreme for the species, causing them to lose their adaptive ability in a different environment, and 2) the small size and isolation of the population make them susceptible to inbreeding and genetic drift. However, the specific mechanisms by which these two factors cause reduced growth have not been well understood.

A large study involving 43 research plots in the Forest Global Earth Observatory (ForestGEO) Network—including a swath of trees at Tyson Research Center, the environmental field station of Washington University in St. Louis—has helped clarify the power of underground fungi to shape forests.

Adivasis in Banteji say they also face arrests, violence and harassment by police and company officialsFor months, they have been living in fear. The people of Banteji, a small tribal village amid the rolling green mountains deep in India’s Odisha state, have lived here for generations. Yet now most only return home for essentials and spend the night sleeping in the jungle. The police raids and violence, they say, could come again at any time.Like so many of India’s tribal communities, known as Adivasis, the people here in the district of Rayagada live in extreme poverty, with little access to education and healthcare. The jungle and hills that surround them also sustain them, as they have done for hundreds of years, providing food, livelihoods, medicines, materials to build their homes and places to graze their animals. These mountains are also their gods. Continue reading…

Hadrian’s Wall, Northumberland: This was once a tree-filled landscape, now we just have remnants – wood sage, honeysuckle, and a stump in the Sycamore GapThe day may be dreich, but the beech trees at Steel Rigg car park are a frenzy of colour: pumpkin-orange, burnt umber, rust. I set off east along Hadrian’s Wall, well wrapped up against wind and rain. Ahead, the massive outcropping of the Whin Sill, its columnar rocks as grey as the heavy clouds above. It’s a familiar sight. I came here years ago to work as a site planner on a Roman dig and have lived in Northumberland ever since.The path twists up the steep stone steps of Peel Crag. The wind whips hair across my face as I pause to study the plants. There’s wood sage, honeysuckle, ivy, bilberry and wood sorrel – remnants of a once tree-filled landscape. By a gate at the top, a group of shaggy black cattle are grazing the uptilted southern slope. Waxcaps gleam in the tufty grass – glossy, bright red buttons and wavy, buttery forms. Continue reading…

To slow the effects of climate change, conserve biodiversity, and meet the sustainable development goals, replanting trees is vital. Restored forests store carbon within the forest’s soil, shrubs, and trees. Mixed forests are especially effective at carbon storage, as different species with complementary traits can increase overall carbon storage.

Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.

Experts predict ‘catastrophic ecosystem collapse’ of UK forests within the next 50 years if action not taken. Other threats to UK forests include competition with society for water, viral diseases, and extreme weather affecting forest management.

Sandy, Bedfordshire: One moment the lime tree is ablaze in early-morning yellow-gold, and the next, the fire has been put outThis shifting season paints itself in two trees outside my window. I rootled in a bag of coloured pencils at half-term for lime and sycamore, and began to draw. Though my sketching skills are limited, I have learned to see colour changes by the week, the day, and even in an instant, with the parting of clouds.The old lime to the right is at the end of a line that once marked the boundary of a Victorian villa. Two weeks ago, my drawings would give it a strong mid-green base, for only the leaves on the outermost twigs curled and furled, all their chlorophyll sucked back into the core. This marked the patchy beginnings of a brief golden age, when previously subsumed carotenoids and xanthophylls gave the lime its first hues of autumn. Continue reading…

Researchers at Nagoya University in Japan have revealed new insights into the interaction between mast seeding plants and the animals that eat their seeds. Hanami Suzuki and Professor Hisashi Kajimura examined the behavior of field mice using seeds from once-in-a-century flowering sasa bamboo plants in central Japan.

Simon Fraser University researchers studying the evolutionary history of flu viruses have found that a new quantitative analysis of how they evolved may help predict future strains. The research draws on a field known as phylogenetics, which focuses on how groups of organisms are evolutionarily related, and is published in the journal Science Advances.

Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.

Shimpling, Suffolk: An imperfect ring of wonderful milkcap toadstools brings to mind how the landscape here is supposed to beThrough the foliage it just looked like some weird plasticated white mess across the ground. Only when you went under the bushes to the exact spot could you see the real magic. It was an almost perfect circle of fungi, and each toadstool a creamy plate – glistening, succulent and as fleshy as a fillet of ox liver – and probably one of 30-plus species known as milkcaps.It struck me as a metaphor for this place, Alpheton Hall Wood. In spring it is strewn with flowers and ringing with birdsong. Most special among the multi-coloured carpet is the soft lemon of oxslips, because Alpheton is one of a suite of Suffolk sites celebrated for being among Britain’s best ancient woodlands and of national wildlife importance.

Review defines gaps hindering uptake and recognition of key mitigation approach

More accurate methods of estimating avoided deforestation are urgently needed

Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study.   The research suggests that tropical forests play a critical role in cooling the land surface — and that effect can play out over considerable distances. 

Research highlights benefits forests bring surrounding regions in terms of cooler air and more rainfallDeforestation has a far greater impact on regional temperatures than previously believed, according to a new study of the Brazilian Amazon that shows agricultural businesses would be among the biggest beneficiaries of forest conservation.The research has important political implications because farmers in Amazonian states have, until now, led the way in forest destruction on the assumption that they will make money by clearing more land.

Research indicates that several pathogenic bacteria can remain contagious on a range of surfaces from hours to days and weeks. While wood as a surface material is known for its antibacterial properties, dry contamination via hands has so far been poorly understood, as most prior research has involved adding bacteria in liquid droplets to materials.

The tropical wood type ipe is popular for building exclusive wooden decks, and in North America and Europe, the demand for the material has increased sharply. Now, a study shows that more than three-quarters of all ipe from the top producing region in Brazil could have been harvested illegally.
