1 BOREAL FORESTS Marion B. and Tesha K. (“Marietta”)

2 LOCATION - South of the Arctic tundra -Latitude: around 60° -In northern regions across North America, Asia, and Europe (“Wikipedia”)

3 CLIMATE ﺵ Sub arctic ﺵ Long Winters ﺵ Dry and cold ﺵ Short summers (mild-warm) 19 hrs. sun ﺵ Winter: 6-8 hrs. sun (“Marietta”)

4 STATISTICS  Avg. annual temp: 0°C (≥-5°C ≤5°C)  Avg. annual precipitation: 100-125cm.  Temperature Range: 41°C (“Blue Planet Biomes”)

5 FLORA TYPES Trees: conifers (evergreens, firs, etc); needles all year long -produce cones instead of flowers (“Coniferous Forest”) --able to endure intense cold and drought during winter (Living in the Environment)s -some mosses and algae grow on ground -needles reduce surface area  loose less water -needle coating=waxy and waterproof -stomata sunken in  wind protection -dark color  absorbs heat  photosynthesis sooner -winter  frozen soil, harsh climate  low plant diversity (“Marietta”)

6 FAUNA Predators (with fur): weasel family, lynx, some tigers -feed on rabbits, squirrels, lemmings, and voles -elk, moose, beavers=large herbivores Birds: insect-eaters (wood warblers), seed eaters(finches, sparrows), omnivores (ravens) and some migratory birds (“Marietta”)

7 Degree of Biodiversity and Biomass Pyramid  Degree of Biodiversity: ~ 1.5  Biomass Pyramid: Tertiary Consumers: owls, some wolves and foxes Secondary Consumers: some foxes, and other furry animals Primary Consumers: Moose, Blue Jay/other birds, some foxes, Beetles, Rabbits Producers: Spruce and other conifers; plants such as Bebb Willows Decomposers: Bacteria (Living in the Environment)
