What is an adaptation that does not help animals survive long winters in the coniferous forest?

Camouflage.

Camouflage is an adaptation that helps animals blend in with their surroundings and avoid being seen by predators. While this can be a helpful adaptation for animals living in the coniferous forest during the summer, it is not as helpful during the winter when there is snow on the ground. This is because the snow reflects light, making it easier for predators to see animals that are camouflaged.
