Research IssueOur ResearchExpected OutcomesResearch ResultsResearch ParticipantsHemlock Tsuga has a disjunct distribution in North America and Asia with 8 to 13 species accepted by various authors. The two species that are native to eastern North America are vulnerable to adelgid damage partly because they have less resistance or tolerance than hemlocks from western North America and Asia. Accurate information about worldwide hemlock diversity and the relationships among species is valuable for nrs.fs.fed.us

Eastern hemlock Tsuga canadensis L. Carri232re, a common native conifer in the eastern United States, exists on the northwestern edge of its range in Minnesota. Eastern hemlock has occurred in Minnesota in smaller disjunct populations for at least 1,200 years, but is now listed in the state as an endangered species.Author: E. Ellingson, S. McNamara, Jim Bradeen, Stan C Hokanson

Effects of diversity of tree species and size on forest ...

For Douglasfir/western hemlock, net basal area growth was negatively correlated with treesize diversity, essentially because recruitment was lower on plots of high treesize diversity. For mixed conifers, net basal area growth tended also to be lower in plots of high treesize diversity, but this was mostly because mortality was higher in plots of higher treesize diversity.Cited by: 143

Exotic Species: Poison Hemlock U.S. National Park Service

Poison hemlock is highly poisonous to humans and animals. It can acts as a pioneer species and quickly colonized disturbed sites. Infestations occur along roadsides, field margins, ditches, marshes, meadows, and lowlying areas, but poison hemlock prefers shaded areas with moist soil.

arthropods 3032, and salamanders 33 live in eastern hemlock stands. Fungal diversity in eastern hemlock stands rarely have been studied, but in general is at best equal to, and generally lower than, that in deciduous forests 3436. Similarly, both plant diversity and abundance of the species in the herbaceous layer of hemlock understories are low.
