Keating’s study focuses on one of the most forested and wild ecoregions in North America, which extends into New York, New England, and Canada and includes Acadia National Park. Here, spruces, firs, and cedars of the northern boreal forest mix with hemlocks and pines of more temperate climates. This combination helps create the appearance, aroma, and ecology of the region, and the trees’ unique botanical traits have been ingeniously utilized by numerous peoples including Iroquois and French explorers, beer brewers, and shipbuilders. Keating concludes with identification guides for the conifers and where they can be found in Acadia National Park.
