A Cultural Landscape Foundation report lists the Holden Arboretum in Kirtland among 10 U.S. landscapes threatened by climate change.
The Foundation recently released Landslide, its annual report on the topic. Sites range from the Cape Hatteras National Seashore to Death Valley Scotty Historic District.
ArbNet is pleased to announce the winners of the 2019 BGCI/ArbNet Partnership Programme! This funding opportunity supports the development of international collaborations between gardens and arboreta for the purpose of exchanging skills, resources and expertise to advance tree conservation. We are excited to see what these partnerships will accomplish over the next year!
Scientists say there is new hope in the fight against a disease that is devastating ash trees.
A study has identified the genes that give trees resistance to ash dieback, which arrived in the UK in 2012 and has now spread to almost every part of the country.
The discovery suggests that trees could now be bred that are unaffected by the epidemic.
The research is published in the journal Nature Ecology and Evolution.
A mysterious disease is starting to kill American beeches, one of eastern North America's most important trees, and has spread rapidly from the Great Lakes to New England. But scientists disagree about what is causing the ailment, dubbed beech leaf disease. Some have recently blamed a tiny leaf-eating worm introduced from Asia, but others are skeptical that's the whole story.
ROYAL BELUM STATE PARK IN PERAK, MALAYSIA—It has been a year of color and sex for the lowland rainforests of Malaysia and Indonesia. This is a "mast year," when dozens of tree species produce bumper crops of flowers, fruits, and seeds simultaneously. Since April, the canopy has been a splendid mosaic of yellow, orange, and red set against green. It has been 5 years since the spectacle was last seen.
On July 25 in Addis Ababa, Ethiopian Prime Minister Abiy Ahmed picked up a spade and started to dig a hole. When he was finished, he gently lowered a sapling into the hole he had dug, and then covered its roots with the loose soil. The tree that he had just planted was one of 350 million planted in Ethiopia that day, part of an unprecedented push to reforest the country — and, in the process, save the world from the climate apocalypse.
Unfortunately, it’s a little more complex than that.

Over half (58%) of Europe’s endemic trees are threatened with extinction, according to assessments of the state of the continent’s biodiversity published today by the International Union for Conservation of Nature (IUCN). The introduction of invasive species, unsustainable logging and urban development are key threats causing the decline of tree species such as the horse-chestnut across Europe.

Studying the rings inside oak trees has allowed scientists to produce one of the most detailed records yet of how the UK's climate has changed over the last millennium.
It reveals a picture of summer rainfall stretching back more than 800 years. Periods of prolonged extreme weather coincided with historical accounts of famines and droughts.
“Toward the Metacollection: Coordinating conservation collections to safeguard plant diversity”, is a publication that is a result of a three-year grant, “Safeguarding Plant Collections”, funded by the Institute of Museum and Library Services. It demonstrates the power of the botanic garden network and the role they play in collective conservation. Overall, stopping plant extinction.
