Trees do not pay taxes. Some seem to avoid death as well. Many of the world’s most ancient organisms are trees, including a 3,600-year-old cypress in Chile and a sacred fig in Sri Lanka that was planted in the third century B.C.
If you were dropped into virtually any region of North America 56 million years ago, you probably would not recognize where you had landed. Back then, at the dawn of the Eocene epoch, the earth was warmer and wetter than it is today. A sea had just closed up in the middle of the Great Plains, and the Rocky Mountains had not yet attained their full height. The continent's plant and animal communities were dramatically different.
In commemoration of the day of the tree, yesterday June 15, 2020 we started planting 500 trees at the Horizontes Forestry Experimental Station , the goal at the end of the year is to plant 10,000 trees in fragile sites of the Station.
As bushfires blackened forests last summer, one tree species was protected by a specialist team of firefighters: the Wollemi pine.
These trees have a deeply ancient lineage dating back to when dinosaurs walked Gondwana 100 million years ago. Back then, rainforests—including Wollemi pines (or their cousins) – covered what became Australia.
An international team of scientists have identified candidate resistance genes that could protect ash trees from the Emerald Ash Borer (EAB), a deadly pest that is expected to kill billions of trees worldwide.
In the new study, published today in Nature Ecology & Evolution, researchers from Queen Mary University of London and the Royal Botanic Gardens, Kew, sequenced the genomes of 22 species of ash tree (Fraxinus) from around the world and used this information to analyse how the different species are related to each other.
Inside the walled gates of the Acharya Jagadish Chandra Bose Indian Botanic Garden located at Shibpur in Howrah district, the chirping of birds gets distinctly louder.
Set up in 1787, the 273 acre garden, located at the other end of the river Hooghly, has turned into a graveyard of trees. Massive trees, hundreds in number, with trunks having a girth of several metres, have fallen all over the garden, completely blocking access to large parts of the campus.
There are a number of broadleaf evergreens that provide structure and screening in the shady garden — hollies, camellias and boxwood all spring to mind. But there are very few evergreen conifers that fit the bill. Most crave sunlight.
There is one notable exception: the hemlock, which is an attractive, fine-textured native coniferous tree that grows large but without the dense, leaden qualities of, say, the Norway spruce or the southern magnolia.
A study carried out at the Institute for Atmospheric and Earth System Research (INAR) of the University of Helsinki modeled how different street-tree alternatives and the location of the trees affect air quality on the pedestrian level. The study was carried out in collaboration by the University of Helsinki, the City of Helsinki and the Finnish Meteorological Institute.
Temperate and tropical dry forests—not just rainforests—are home to thousands of unique tree species, a new study reveals.
Scientists studied data from more than 10,000 forest and savanna sites across the Americas, discovering unique and special tree biodiversity.
Conservation efforts have traditionally focussed on rainforests, partly because they contain so many tree species.
Have you been involved in collecting, buying or selling tree seed or seedlings for restoration efforts in southeast Asia? If yes, please answer to this short survey and you will help develop knowledge and tools to support restoration projects access fit-for-purpose planting material.
It would really help us out if you could respond to this survey. We also kindly ask you to distribute the survey through your contacts, so that we can reach as many organisations as possible.
