这本地图集记录了美国东部80种常见树种的当前和未来可能的分布，并提供了定义这些分布的环境特征的详细信息。还包括这些物种的生活史、特征和摘要统计的概述。许多数据来自森林调查和分析(FIA)数据，这些数据与地理信息系统中的33个环境变量相结合进行分析。生活史信息，包括再生和干扰特征，是通过文献生成的，并以数据库格式提供。摘要统计数据提供了美国东部树种的总体视角。构建了回归树分析模型，以确定在两种全球气候变化情景下每个物种未来可能的栖息地。结果表明，根据情况，气候变化后，美国东部80个物种中可能有4-8个物种灭绝。附录提供了有关使用的数据和方法的信息，包括迁移模型的演示。
This atlas documents the current and possible future distribution of 80 common tree species in the Eastern United States and gives detailed information on environmental characteristics defining these distributions. Also included are outlines of life history characteristics and summary statistics for these species. Much of the data are derived from Forest Inventory and Analysis (FIA) data, analyzed in concert with 33 environmental variables within a geographic information system. Life history information, including regeneration and disturbance characteristics, were generated via the literature and are provided in data base format. Summary statistics offer an overall perspective on the tree species of the eastern United States. Regression tree analysis models were constructed to determine possible future habitat for each species under two scenarios of global climate change. Results show that, depending on the scenario, 4-8 of the 80 species could be extirpated from the Eastern United States after climate change. Appendices provide information on the data and methods used, including demonstration of a migration model.
