Forests

Urban areas are already experiencing impacts of a changing climate including increased temperatures, flooding, and extreme storms. These impacts are projected to increase in frequency and magnitude over the next century, leading many cities to develop plans to adapt and prepare for these challenges. Increasing tree canopy is often considered in urban climate change adaptation plans, where trees can help reduce local heat island effects, control storm water, and improve air quality. Although urban trees can be an important part of adaptation solutions, they also can be vulnerable to the impacts of climate change. Harsher summer temperatures, potential summer droughts, heavy winds, flooding, and increased pests and diseases can all stress urban trees. These urban trees may be experiencing stress from improper planting, restricted rooting conditions, road salt, and air pollution already, and therefore extremely vulnerable to climate change.

Extreme Precipitation and Trends There is clear evidence that precipitation in the Northeast is more intense than it was in the past. The increase in the Northeast has been greater than any other region in the U.S. (Figure 1). Between 1901 and 2014, total annual precipitation…

Taking action now can help forested watersheds prepare for and adapt to a changing climate. Forested watersheds improve water quality and enhance water storage, naturally regulate streamflows, reduce flood damages and stormwater runoff, replenish groundwater and provide a myriad…

Growing Season Length Warmer temperatures have resulted in a longer freeze-free season and longer growing season across the region (Frumhoff et al. 2007, Kunkel et al. 2013). The freeze-free season, which is the period between the last occurrence of 32 °F in the spring and the…

The changing climate presents challenges and opportunities for U.S. agricultural production, forest resources, and rural economies. These threats have significant implications not just for farmers, ranchers, and forest landowners, but for all Americans. Land managers across the…

A changing climate poses risks for urban forests. Some forest pests may benefit from warmer temperatures, leading to tree damage and mortality. Heavy rain events and some types of storms may also increase in the coming decades, which can increase stormwater runoff, flooding,…
