The past few months have highlighted the importance of parks and nature in cities.
Sonic tomography, or the use of sound waves to detect decay in trees, is a relatively new technology available to arborists.
Thousands of trees are struck by lightning every year. These trees will have varying degrees of damage ranging from complete shattering and destruction of the tree, to a slow lingering death, to virtually no apparent damage at all (Figure 1).
Join Jenica Allen and Bethany Bradley to learn about new tools for identifying and prioritizing range-shifting invasive plants coming soon to a landscape near you.
Conifers are commonly planted in North America to provide year-round screening, as windbreaks or as focal trees in the landscape.
Iconic tree species include those native trees that once dominated the typical American city landscape. The American elm and chestnut are the first two that come to mind, and now ash trees are similarly under significant threat of loss.
Intensively managed landscapes, like those found in many public gardens, attempt to mitigate the impact of significant weather events through irrigation, improving soil characteristics, and mulching.
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.
Sunflower is a unique model species for assessing crop responses and adaptation to climate change. We provide an initial assessment of how climate change may influence the abiotic and biotic environment of cultivated sunflower across the world.
