The arrival of new plant pests and diseases is likely to severely damage UK trees and woodlands in the coming decades, new research shows.
The ash dieback epidemic prompted the government to assess all pests and diseases that could potentially enter the UK and affect our trees and agricultural crops.

Getting zapped with millions of volts of electricity may not sound like a healthy activity, but for some trees, it is. A new study, published in New Phytologist, reports that some tropical tree species are not only able to tolerate lightning strikes, but benefit from them. The trees may have even evolved to act as lightning rods.
The research was led by Evan Gora, a forest ecologist at Cary Institute of Ecosystem Studies. Gora studies how lightning impacts biodiversity and carbon storage in Panama's tropical forests.

A team of botanists with members from Muse–Museo delle Scienze, Udzungwa Corridor LTD, Via Grazia Deledda and the National Museum of Kenya has discovered a new species of tree growing in the mountainous rain forests of Tanzania. In their paper published in the journal Phytotaxa, the group describes how and where the tree was found and its characteristics.

Forests provide many ecosystem services, including microclimate regulation, biodiversity preservation, air and water purification, and soil protection. Together with the oceans, they are one of the two most important carbon sinks, due to their capacity to store carbon in the soil and in tree biomass.
As such, promoting fast-growing trees could strengthen efforts to mitigate climate change. This raises a key question for forest managers: which tree species have the greatest mitigation potential?

The reason why so many tree species can coexist in species-rich forests has long been a subject of debate in ecology. This question is key to understanding the mechanisms governing the dynamics and stability of forests. An international team of scientists led by the Helmholtz Centre for Environmental Research (UFZ) has now discovered unexpected patterns in the spatial distribution of tree species, as reported in the journal Nature.
In the most comprehensive global analysis of genetic diversity ever undertaken, an international team of scientists has found that the genetic diversity is being lost across the globe but that conservation efforts are helping to safeguard species.
The landmark study, published in the pre-eminent scientific journal Nature, was led by Associate Professor Catherine Grueber from the School of Life and Environmental Sciences and a team of researchers from countries including the UK, Sweden, Poland, Spain, Greece and China.

A major study of botanic gardens around the world has revealed their struggles with one fundamental aim: to safeguard the world's most threatened plants from extinction.
Researchers analyzed a century's worth of records—from 1921 to 2021—from fifty botanic gardens and arboreta currently growing half a million plants, to see how the world's living plant collections have changed over time.
The Morton Arboretum is pleased to announce it has awarded $7.9 million in federal urban and community forestry funding to 39 Illinois organizations—ranging from government entities and community groups to higher education institutions and other nonprofits—for urban and community forestry work in priority areas across the state.
Awarded organizations will collectively plant and care for more than 8,300 trees, prune more than 1,300 trees in need of maintenance, remove at least 240 dead, high-risk or invasive trees, and train 210 staff or community members in forestry work.

Scientists and botanists are continuously exploring nature’s vast variety, making tree and plant discoveries that highlight the richness of our planet’s biodiversity.
These findings spark excitement and curiosity, offering fresh perspectives on the vast array of plant species still awaiting exploration. Most recently, experts have added to the world of botanical discoveries by naming six new tree species.
These species were identified during an exhaustive comparison of dried plant specimens gathered from across the Neotropics.

For newly sprouted trees, cattle and deer are usually a curse, come to nibble away what little body they have. But an advance article posted in October in the Annals of Botany suggests that in certain circumstances, the browsing animals could be a blessing in disguise: Losing leaves may help California oak seedlings conserve water during drought, boosting their chances of surviving.
