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...

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...

Conifers are commonly planted in North America to provide year-round screening, as windbreaks or as focal trees in the landscape. However, conifers including certain species of spruce, pine, hemlock, cedar and fir planted in northern areas of North...

Island systems are among the most vulnerable to climate change, which is predicted to induce shifts in temperature, rainfall and/or sea levels. Our aim was: (i) to map the relative vulnerability of islands to each of these threats from climate change...

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...

An Urban Tree Canopy (UTC) assessment, which provides a measure of a community’s tree canopy cover, is important for understanding the extent of a community’s forest or tree resource. UTC assessments are often used for establishing and implementing...

Improving urban forests is one of the solutions to achieving several of the United Nations Sustainable Development Goals and making cities healthier and more livable for people. Priority should be given to protecting mature trees and promoting long‐...

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....

North American forests and forest management institutions are experiencing a wide range of significant ecological disturbances and socioeconomic changes, which point to the need for enhanced resilience. A critical capacity for resilience in...

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...
