When I arrived years ago at the piece of land I now garden, I saw it as a blank canvas and set about madly planting things, imagining my efforts would bring every square foot to life. I did not understand then that the heavy lifting had already been done — and probably by some blue jay, or maybe a squirrel.
Work has started to fell 5,000 trees infected with ash dieback at Westonbirt Arboretum.
The site's 200-acre Silk Wood has been closed for the removal of 2,000 ash trees over the next four weeks.
A further 3,000 trees infected with the serious fungal disease will be removed at a later date.
New species of other trees will be planted in the next five years to ensure the long-term future of the woodland near Tetbury, Gloucestershire.
COLUMBIA FALLS, Mont. (AP) — The U.S. Fish and Wildlife Service last month proposed listing the whitebark pine as threatened under the Endangered Species Act.
For the last 24 years, Glacier National Park has been quietly working to conserve the species over its 1 million acres of wildlands.
It is no small task.
The Park first began collecting cones from “plus” trees in 1997. Plus trees are adult, cone-bearing trees that have shown resistance to blister rust, noted Park vegetation biologist Dawn LaFleur.
Poorly planned and executed tree planting schemes can harm the environment, experts warned as they set out “golden rules” for restoring forests.
Planting trees to suck up carbon emissions can be presented as an “easy answer” to tackling the climate crisis, but large-scale plantations can actually cause more problems than benefits, scientists have said.
We would like to share with you the publication of the new Quercus
An estimated 31% of the world’s oak species are threatened with extinction according to data compiled in a new report by The Morton Arboretum and the International Union for Conservation of Nature (IUCN) Global Tree Specialist Group, The Red List of Oaks 2020. The report details for the first time the distributions, population trends and threats facing the world’s estimated 430 oak species, and will serve as a roadmap for conservation action.
MORONGO BASIN — Evolutionary biologist Jeremy Yoder will spend time this spring collecting tissue samples from 300 Joshua trees across the desert, hoping to produce a genetic map of them.
The goal is to allow scientists to identify genetic variances in the species.
Scientists need that information to provide insights into which of the trees are more adaptable to climate change. The genetic data would be the first of its kind for the desert species, and could serve as a model for genetically informed desert conservation.
One in four hardwood trees in the eastern United States was once an American chestnut. But no one today can take a walk in these woods beneath the once towering chestnut trees because the species is functionally extinct.
Researchers at Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv) have compiled the world's most comprehensive list of known plant species. It contains 1,315,562 names of vascular plants, thus extending the number by some 70,000—equivalent to about 20%. The researchers have also succeeded in clarifying 181,000 hitherto unclear species names. The data set has now been published in Scientific Data. This marks the culmination of ten years of intensive research work.

On a weekday morning in August, just one pickup truck sat in the sprawling visitors’ parking lot here at the U.S. Department of Agriculture’s (USDA’s) Forestry Sciences Laboratory. A decadeslong decline in research funding had been slowly quieting the place—and then came the pandemic.
