The elm tree can return to the British countryside, given a helping hand, according to a new report.
More than 20 million trees died during the 1960s and 1970s from Dutch elm disease.
In the aftermath, the elm was largely forgotten, except among a handful of enthusiasts who have been breeding elite elms that can withstand attack.
With increasing regularity, Californians are witnessing firsthand the destructive power of wildfires. But not everyone sees what happens after the flames die down, when debris is cleared, homes and lives rebuilt — and trees replanted to help nature recover.
New research led by UCLA evolutionary biologist Victoria Sork examines whether the trees being replanted in the wake of California’s fires will be able to survive a climate that is continuing to warm.
Even on a frigid morning, when the last scarlet leaves clung to an oak tree and fallen gingko leaves blurred the pathways, a woman sat cross-legged on a stone bench in the Brooklyn Botanic Garden, wrapped and rapt. I have no idea who she was or how long she’d been sitting there, but in the days since I spotted her, she has lingered in my mind as an image of serenity stolen from the screeching tumult of urban life.
We pass a Palo María tree that’s been illegally cut and hauled away (they fetch close to US $10,000) and on the drive in to the Gardens this morning Gerlowski pointed out the nascent signs of development along the road – a barbed wire fence here, a cement slab there, earth that has been carved out of the ridge of the river’s canyon for the entrance to a future house or hotel. There are legal and illegal construction projects galore.
A Cultural Landscape Foundation report lists the Holden Arboretum in Kirtland among 10 U.S. landscapes threatened by climate change.
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.
