Abstract: Eastern hemlock (Tsuga canadensis (L.) Carr.) is an important tree species in the mixed-species conifer forests of northern New England and adjacent Canada. Hemlock is very tolerant of understory conditions; consequently, it responds differently to various silvicultural treatments. In a long-term study at the Penobscot Experimental Forest in east-central Maine, shelterwood silviculture reduced the hemlock component in regenerating stands compared to parent stands, while hemlock increased in abundance and dominance under selection silviculture. On sites where hemlock is common, managers have some control over its prevalence through silviculture.
