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).
Conifers are commonly planted in North America to provide year-round screening, as windbreaks or as focal trees in the landscape.
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
ManagementEmerald ash borer (Agrilus planipennis) was first discovered in southeastern Michigan in 2002.
Urban trees serve a critical conservation function by supporting arthropod and vertebrate communities but are often subject to arthropod pest infestations.
The first TGI report, published in 2015, identified eight critical gaps slowing the transfer of stress-adapted trees from upstream research to forest owners and managers. The gaps fell into three categories: Innovation, Policy, and Markets.
U.S. urban land increased from 2.6% (57.9 million acres) in 2000 to 3.0% (68.0 million acres) in 2010. States with the greatest amount of urban growth were in the South/Southeast (TX, FL, NC, GA and SC).
