Snow crystals
A forest is only then a forest, when a high concentration of trees is given. Woods bear a great number of species, produce a majority of oxygen in our world; they are huge reservoirs of water and stabilize the ground with their tangles of roots.
Snow
Snow consists of ice crystals. Their formation within clouds depends on the presence of ice nucleating particles and temperatures lower - 12°C.
Crystals possess a hexagonal symmetry, being prism-shaped at lower temperatures and dendrite-shaped at higher temperatures.
Temperate deciduous forests hibernate without functional leaves. Most trees throw off all leaves already in autumn to be protected from desiccation in winter frost periods.
Layers of snow are excellent thermal conductors and additionally protect all life underneath from frost damages in the cold season.
Waiting for the spring time
Most life forms hibernate together with their leafless trees. Especially accumulations of deadwood contain remarkable numbers of species, such as insects, spiders, mites or nematodes. Some already begin under their snow cover to prepare themselves for the warmer season.
When all snow is gone, winter colors in red, yellow, brown and some green reappear. Early blossoming plants are already germinating.
