The U.S. Army owns many acres of forested training lands. Management of these forest lands can impact the Army s ability to meet training goals as these lands have implications to noise mitigation and threatened and endangered species populations. To support the need to manage these forested areas, the Environmental Processes Branch of the US Army Engineer Research and Development s Construction Engineering Research Laboratory conducts ongoing studies of forest lands, including the possible implications of climate change on forests. An important subtopic of that study is the microclimate a forest creates under and within its canopy; a forest micro-climate can affect a wide variety of factors within the forest including how sound travels, vegetation regeneration, and faunal interactions. This report supports that important subtopic by creating an annotated bibliography of works related to how microclimates varied within forests and how they impacted environmental components within the forest. The resulting information will provide insight on how to design future work to capture relevant data and how to interpret those results.
