In the Jura massif, where snowfalls are usual and where the snow cover is long and abundant, the plant species have adapted. This is particularly the case with evergreen long-needle conifers which, in winter, have a much larger intercept area than hardwoods. Specific morphological adaptations, such as the columnar structure or the drapery branches of old spruces, make it possible to limit this retention. The resistance of the tree will actually depend on its ability to unload. It is facilitated by the long branches which can bend under the weight of the snow.
