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 -winterfrozen soil, harsh climatelow plant diversity
(“Marietta”)
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
