Adaptations

To survive the cold winters over at Yellowstone, bears eat excess in the fall to keep them nourished during their hibernation. This helps them survive during the cold winter.

Wolves have many adaptations to survive the winter. Their long legs help them walk in deep snow. They’re also narrow-bodied, for greater efficiency when hunting. And lastly their thick wooly coats keep them warm.

Many birds migrate to warmer weathers when it gets cold. This adaptation allows them to survive brutal winters. When it gets warmer they will return.

Elk have a unique adaptation that allows them to stand on frigid waters for long periods of time. This can help them get away from predators like wolves.

Conifers retain their needles through the winter, which extends their ability to photosynthesize.

Aspens and cottonwoods contain chlorophyll in their bark, allowing them to perform photosynthesis before they produce leaves.

The lodgepole pine have special seeds that require environmental factors to open. The seeds will stay shut until it reaches temperatures of 40-60 degrees celsius.

Evergreen trees do not drop their leaves all at once in the colder seasons like most trees do. This adaptation of reduced-leaf fall means the tree can use it's leaves to increase photosynthesis for energy to survive the cold, harsh climates.
