RHS Lindley Library – Digital collections. Varieties under threat From its earliest years, the RHS cultivated a rich apple tree collection.

RHS Lindley Library – Digital collections

The substantial orchard at its first official garden at Chiswick (1823–1903), was a living reference library for the identification of new fruit and the reliable growth of new apple trees. Robert Thompson, the gardener in charge, painstakingly described each variety in his dedicated apple books. He helped nurserymen and gardeners choose varieties that would grow well and give a range of different flavours across the seasons. However, by the late 1800s, British apple growers began to struggle against cheaper imported apples from North America, France, Australia and New Zealand.

This threat to a vital part of our food heritage was of great concern to the RHS. In recent years, the Wisley orchard has focused on varieties of dessert and cooking apples suited to growing in gardens rather than to commercial production.

It sprouts. It grows. Tree root identification saves ancient caves and the forest above them. Ancient burial caves dating to approximately 1800 years ago are under threat in Galilee, Israel.

Tree root identification saves ancient caves and the forest above them

The site is the necropolis of Beit She’arim, a UNESCO World Heritage site. Tree roots from the mixed forest growing overhead have begun to penetrate the soft limestone ceiling, causing a risk of structural weakening and collapse. It became necessary to remove the trees with roots damaging the cave, but ideally to do so without needing to indiscriminately fell the entire forested area. The Social Life of Forests. The Social Life of Forests By Ferris Jabr Photographs by Brendan George Ko As a child, Suzanne Simard often roamed Canada’s old-growth forests with her siblings, building forts from fallen branches, foraging mushrooms and huckleberries and occasionally eating handfuls of dirt (she liked the taste).

The Social Life of Forests

Her grandfather and uncles, meanwhile, worked nearby as horse loggers, using low-impact methods to selectively harvest cedar, Douglas fir and white pine. They took so few trees that Simard never noticed much of a difference. Gavin Van Horn, Breathing Trees - The Learned Pig.

The woods are shaggy with green and, in this autumnal light, aglow. My mind is also rank with vegetation. Filled up with verdant ideas I brought to these woods about the porous boundaries between plant and animal kingdoms; latticed with thoughts about our kinship and dependence on these beings who create energy from sunlight; saturated with the emerging research on the many ways plants communicate with one other, with fungi, with insects, and with us.

The crowning glory of Kew

Picador. The UK’s Royal Botanic Gardens at Kew near London are famed as much for the buildings and grounds, as the ground-breaking, world-leading research into plants that is carried out there. And Kew’s most iconic building is undoubtedly the Palm House, which in many respects is the focal point of the Gardens. Kew’s buildings and plants are masterfully combined by Kate Teltscher in Palace of Palms which places the Palm House and its precious plant contents centre-stage.

Satellites could soon map every tree on Earth. Terrestrial ecosystems are defined in large part by their woody plants.

Satellites could soon map every tree on Earth

Grasslands, shrublands, savannahs, woodlands and forests represent a series of gradations in tree and shrub density, from ecosystems with low-density, low-stature woody plants to those with taller trees and overlapping canopies. Accurate information on the woody-vegetation structure of ecosystems is, therefore, fundamental to our understanding of global-scale ecology, biogeography and the biogeochemical cycles of carbon, water and other nutrients. Writing in Nature, Brandt et al.1 report their analysis of a massive database of high-resolution satellite images covering more than 1.3 million square kilometres of the western Sahara and Sahel regions of West Africa. The authors mapped the location and size of more than 1.8 billion individual tree canopies; never before have trees been mapped at this level of detail across such a large area.

Yet more challenging is the identification of tree species. Urban Trees, Whether Native Or Introduced Species, Provide The Same Ecological And Social Services. Katie Holten on Turning Words and Paragraphs into Whole Forests. Katie Holten’s tree project is the best example I’ve encountered in recent memory of a simple idea that carries the weight of something much more complex.

Katie Holten on Turning Words and Paragraphs into Whole Forests

Holten, an Irish-born visual artist based in New York City, has created an alphabet of trees that she uses to translate text into trees. About Trees, the resultant anthology, is a provocative examination on the nature of language and our relationship with the natural world as we enter a new age, what many geologists are calling the Anthropocene. As the breakdown of the natural world coincides more and more with that of the human world, and our interdependence becomes more apparent, such explorations grow more urgent. This urgency is one of the guiding impulses behind the new Parapoetics series published by Broken Dimanche Press, of which About Trees is the first title.

Aspirin: Turn-of-the-Century Miracle Drug. Headache?

Aspirin: Turn-of-the-Century Miracle Drug

Fever? Muscle pain? “Take two aspirin and call me in the morning.” Like most of us, when you experience everyday aches and pains, a bottle of aspirin is probably the first thing you reach for. Yet, while aspirin has been one of the most popular pharmaceutical agents of the past one hundred years, it is actually a synthetic derivative of the natural substance salicylic acid—the associated healing properties of which have been known for millennia. View from the sky sees new hope for restoring degraded forests. More than half of the world’s aboveground carbon is stored in tropical forests, and many of these forests are under threat of development. When development happens the degraded forest is thought to have little ecological value. However, a new study published in Science by Christopher Philipson and colleagues comparing naturally regenerating and actively restored logged tropical forests have found forest restoration is a solution capable of both replenishing carbon storage and preserving biodiversity.

While this concept isn’t new, the adoption of restoration practices has been impeded by uncertainties over its effectiveness. The researchers studied an area of tropical forest in Malaysian Borneo, where agricultural activities have caused soaring deforestation rates for years. The study site was heavily logged in the 1980s and subsequently protected from further logging or conversion to plantation agriculture. “Chris Philipson and all of us came together.

Decoding Palms: Deciphering Plant Mysteries One Publication at a Time. When you think of Los Angeles, there are some iconic things that come to mind: the Hollywood Sign, the Santa Monica pier, the Hollywood Walk of Fame — and palm trees. Call up a photo of Los Angeles’ cityscape, and chances are you’ll see palm trees. They are ubiquitous throughout the city, growing along major boulevards and picturesque residential streets, populating parks and framing beachside boardwalks. While today it’s hard to conjure up imagery of Los Angeles without these towering plants, that was not always in the case. Budding History: On Nationalism and Cherry Blossoms. Why Some Buddhist Monks Ordain Trees. All over the world, trees are a symbol of natural ecology that environmentalists rally to protect. In Thailand, anthropologist Nicola Tannenbaum writes, they have a unique method of doing that: symbolically ordaining trees as monks. Tannenbaum writes that Buddhist monks have long been involved in social movements and development efforts in Thailand.

In the early 1980s, they were part of missionary and development programs, supporting the national goals of education, development, and modernization. However, many of them came to see modernization, at least in the form of industrialization, urbanization, and the spread of Western values, as a problem. One particularly important thinker was the monk Buddhadasa, who tied the Buddhist belief in connections among all living beings to ecological work.

Why Learning the Names of Trees Is Good for You. When you walk through the woods, or around your neighborhood, do you recognize the trees you see? It might seem like knowing the names of trees has no particular value. But philosopher Christian Diehm argues that distinguishing species may offer a different way of seeing “nature” that could transform our view of the world around us.

More than 35 years after it was first seen, researchers have described Coccoloba gigantifolia, a tree species from the Brazilian Amazon with gigantic leaves that can reach 2.5 meters (8 feet) in length.Although C. gigantifolia has been known to the public and the scientific community for a long time, describing it formally and giving it an official name was essential to be able to assess its conservation status and design conservation strategies to protect it, the researchers say.The species is rare and likely has disjointed populations occurring in a rapidly changing landscape, and the researchers recommended listing it as endangered on the IUCN Red List.

At the National Institute of Amazonian Research (INPA) in Manaus, Brazil, a framed exhibit of a massive dried leaf has been a local attraction for decades.
