Tree Equity for Climate and Health: State and Local Applications

The legacy of institutional racism including redlining and other discriminatory policies have paved the way for an urban landscape that is deeply divided. Too often, a map of tree canopy is also a map of income and race, with corresponding public...

Using botanic gardens and arboreta to help identify urban trees for the future

Diversification of urban forests is essential to enhance their resilience to future biotic
threats as well as those posed by a changing climate. Arboreta and botanic gardens
host a wide range of plant material that can be evaluated to...

The state of the world’s urban ecosystems: What can we learn from trees, fungi, and bees?

Positive interactions between people and nature inspire behaviours that are in harmony
with biodiversity conservation and also afford physical and mental health benefits.
Since most people live in towns and cities, urban greenspaces are...

The global tree restoration potential

The restoration of trees remains among the most effective strategies for climate change
mitigation.We mapped the global potential tree coverage to show that 4.4 billion hectares
of canopy cover could exist under the current climate....

Bartlett: Sonic Tomography

Sonic tomography, or the use of sound waves to detect decay in trees, is a relatively new technology available to arborists.  This technology uses the differential speed of sound as it moves through solid wood, decayed wood, or hollow space to create a...

Assessing the vulnerability of Australia’s urban forests to climate extremes

Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
ecosystems. Tree failures will cause economic losses and jeopardize...

A consistent species richness–climate relationship for oaks across the Northern Hemisphere

Although the effects of climate on species richness are known, regional processes
may lead to different species richness–climate relationships across continents
resulting in species richness anomalies, especially for tropical groups....

Wood and water: How trees modify wood development to cope with drought

Drought is a recurrent stress to forests, causing periodic forest mortality with enormous economic and environmental costs. Wood is the water‐conducting tissue of tree stems, and trees modify wood development to create anatomical features and hydraulic...
