Abstract
This chapter focuses on reconstructing the history of vegetation development in southern Alexander Archipelago (AA) of southeast Alaska during and after deglaciation up to the present day. It also summarizes key findings from recent paleoceanographic research in the Gulf of Alaska to provide a detailed, well-dated record of late Quaternary climate changes for the region. Understanding the regional climate history contributes to the reconstruction of late Quaternary glacial history and the timing of deglaciation, as it establishes minimum limiting dates for possible human occupation of southeast Alaska and northern coastal British Columbia (BC). This regional climate history is essential for recognizing relationships between the timing of climate changes and major ecological changes, and subsequent cultural development and adaptations. The reconstructed vegetation history of southern Alexander Archipelago since the onset of deglaciation provides important insights into the resources available to the earliest settlers and how these resources changed over time. The vegetation history presented here is based on dated pollen records from five unpublished sites and two previously published sites from the region. These records establish the timing and nature of changing terrestrial ecosystems in the southern AA.
