short cool summers and

long harsh winters with

plentiful snow

Temperature• Soil freezes in winter• Winters may last more than 6 months• humid, because temperatures are low enough all year to prevent evaporation

Rainfall• 25-100 cm of precipitation per year(mostly snow)• Many lakes, ponds, and bogs

Climate

Locations

• Southern ½ of Canada• Northern Europe• Much of Russia

Must adapt to snowywinters, which may be “dry” for trees(moisture doesn’t soak into ground)

Adaptations • needles prevent water loss• larches lose needles in fall• flexible branches bend under heavy snow• snow slides off of pyramid shaped trees

Plants

Must adapt to long winters

Adaptations: • active in summer(may hibernate in winter)• birds migrate to warmer climates in winter• few reptiles and amphibians because of cold

Animals
