  2. Genera • 3 main genera within Cupressaceae • Chamaecyparis • Chamaecyparis thyoides: Atlantic white cedar • Thuja • T. occidentalis: Northern/Eastern white cedar • Juniperus • J. communis: Common juniper • J. virginiana: Eastern red cedar • J. horizontalis: Creeping juniper

  3. Defining Characteristics • Coniferous gymnosperms • Trees or shrubs • Common habitats include swamps and other low-lying habitats • Exception: Juniperus tend to grow in dryer habitats • Evergreens with leaves made from scales • Female cones are small and leathery or woody • Cones are made up of small scales • Juniperus have berry-like cones • Bark is leathery and deeply grooved

  4. Cones • Female cones are small and leathery or woody • Cones are made up of small scales • Note: scales on leaves Thuja occidentalis (White Cedar) http://www.bio.brandeis.edu/fieldbio/Sylvain/website%20pics/cedar_cones_965.jpg

  5. Cones • Juniperus have berry-like cones Juniper communis (Common Juniper) http://media-2.web.britannica.com/eb-media/74/10574-004-A8463037.jpg

  6. Bark • Bark is leathery and deeply grooved Chamaecyparis thyoides Atlantic White Cedar http://www.nearctica.com/trees/conifer/cupress/Cthyoid3.jpg T. occidentalis (White Cedar) http://www.uwgb.edu/BIODIVERSITY/herbarium/gymnosperms/thuocc_bark01_web400gf.jpg

  7. Northern MN Cupressaceae • Thujaoccidentalis (Northern white cedar) are found throughout northern MN, especially in damp, shady environments. Some of the largest the author has seen are on the north shore of Lake Superior. http://www.stolaf.edu/academics/naturallands/media/woodlands/coniferous/white_cedar_3.JPG

  8. Northern MN Cupressaceae • White-tail deer prefer cedar to other forage, especially in the winter. Evidence of this can be seen in “browse lines” along lake shore. • The success rate of white cedar saplings is extremely low in area where the whitetail deer population is high
