  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 • Sub arctic • Long Winters • Dry and cold • Short summers (mild-warm) 19 hrs. sun • 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 (“Marietta”) • 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

  7. Degree of Biodiversity and Biomass Pyramid • Degree of Biodiversity: ~ 1.5 • Biomass Pyramid: (Living in the Environment)
