    Description

    Alaskan forests cover one-third of the state’s 52 million ha of land (Parson et al. 2001), and are regionally and globally significant. Ninety percent of Alaskan forests are classified as boreal, representing 4 percent of the world’s boreal forests, and are located throughout interior and south-central Alaska (fig. A1-1). The remaining 10 percent of Alaskan forests are classified as coastal-temperate, representing 19 percent of the world’s coastal-temperate forests (National Synthesis Assessment Team 2003), and are located in southeast Alaska (fig. A1-1). Regional changes in the disturbance regimes of Alaskan forests (Wolken et al. 2011) directly affect the global climate system through greenhouse gas emissions (Tan et al. 2007) and altered surface energy budgets (Chapin et al. 2000, Randerson et al. 2006). Climaterelated changes in Alaskan forests also have regional societal consequences, because some forests are in proximity to communities (both urban and rural) and provide a diversity of ecosystem services (Reid et al. 2005, Wolken et al. 2011).
