Trees and forests in our cities and towns are assets to all who live there. Whether on public or private property, tree canopy and woods or forests add beauty, habitat, and a cooling, calming presence for all to see, feel, and enjoy, if only from a distance. Accessibility implies a different level of engagement, however, and for public trees, lands, and easements this means that everyone can peaceably enjoy these natural and cultural resources in perpetuity. Arborists and urban foresters can play a role in helping residents to sustainably enjoy the many benefits derived from trees. This...

The purpose of this report is to aid in understanding the future impacts of urban forests on climate change mitigation at the county level across the conterminous U.S. This report combines projected changes (2010 to 2060) in urbanization and associated urban tree cover to better understand urban forest impacts related to climate changes. The report estimates projected changes in urban forests related to carbon storage, building energy use and power plant emissions. Two types of projections were developed: Part 1 addresses projected changes in these effects given projected urban growth;...

The coordination of traits from individual organs to whole plants is under strong selection because of environmental constraints on resource acquisition and use. However, the tight coordination of traits may provide underlying mechanisms of how locally adapted plant populations can become maladapted because of climate change.

Accurate knowledge of the historical characteristics of forest ecosystems is important because it provides baseline information for research and management, and a reference point for guiding restoration treatments. Wisconsin forests have undergone drastic changes in structure after Euro-American settlement due to logging, selective cutting, and fire exclusion. Currently, no literature quantifies and maps forest density and other structural metrics at scales for restoration of historical forest ecosystems. Therefore, Hanberry and Dey (2019) used historical surveys to reconstruct historical...

Climate change is shifting forest tree species distributions across elevational and latitudinal gradients, and these changes are often pronounced at ecotones where species meet their climatic bounds and are replaced by other species. Using an extensive ecotone composed of lower-montane white fir (Abies concolorvar. lowiana) and upper-montane red fir (Abies magnificavar. magnifica) in the central Sierra Nevada range of California, USA, we (1) examined how the demographics of the ecotone have responded to recent climate using a field observational study and a historical dataset, (2) quantifie...

As the most remote archipelago in the world, the Hawaiian Islands are home to a highly endemic and disharmonic biota that has fascinated biologists for centuries. Forests are the dominant terrestrial biome in Hawai‘i, spanning complex, heterogeneous climates across substrates that vary tremendously in age, soil structure, and nutrient availability. Species richness is low in Hawaiian forests compared to other tropical forests, as a consequence of dispersal limitation from continents and adaptive radiations in only some lineages, and forests are dominated by the widespread Metrosiderosspecie...
