As the climate has changed in Alaska over the past several decades, invasive plants and area burned by wildfires have both increased. Invasive plants are non-native species that have been introduced from a different region. Yet not all non-native species are invasive. Invasive species are often defined by three features:
Originate from another region (non-native).
Spread rapidly or aggressively, often outcompeting native plants.

As the climate changes over the 21st century, the Puget Sound region’s urban forest will be affected by changing temperatures and precipitation regimes, leading to implications for the people who depend on its ecosystem services.
Severe tropical cyclones present significant challenges for managing invasive species in the Pacific Islands. As climate change intensifies these storms, the impact on ecosystems becomes more severe, creating opportunities for invasive species to spread. For example, damage from storms like Typhoon Dolphin in 2015 likely worsened invasive species spread, such as that of the little fire ants and coconut rhinoceros beetle, threatening both ecosystems and livelihoods.

Forests across the United States are expected to undergo numerous changes in response to the changing climate. The Forest Adaptation Menu of Strategies and Approaches provides a collection of resources designed to help forest managers incorporate climate change considerations into management and devise adaptation tactics.

Northern hardwood forests in New England and New York are already being affected by climate change, which creates challenges for sustaining the ecological, economic, and cultural benefits that these forests provide. There are many adaptation management actions that can address these key challenges. Adaptation actions are informed by site-specific conditions, including historical land-use legacies, and local manager knowledge and expertise.

Pennsylvania Climate Change Projections for Individual Tree Species
Pennsylvania's forests will be affected by a changing climate during this century. These handouts summarize projected changes in tree species habitat for four regions in Pennsylvania and provide the complete model results for those regions. Most handouts were updated in 2023.

The Northern Forests of the Midwest and Northeast regions are home to a diversity of ecosystems and tree species. Anticipated climate change effects, such as increased temperatures, extended growing seasons, variable precipitation, reduced snowpack, and earlier melt, and episodic precipitation events, can interact to increase drought risk and put stress on forest ecosystems. Droughts may impact the unique characteristics of these ecosystems, affecting forest vigor and productivity, carbon storage, and water yield and quality.
