Climate Change Effects Snowfall and Snowmelt in the Northern Rocky Mountains

Climate change can affect snowfall and subsequent melting worldwide in various ways. Global temperature rise affects the seasonal time and leads to the first snowfall in winter and late meltdown in early spring. This extended the summer without snow. Also, there may be a warm spring weather in winter. This could cause rain instead of snow. In a typical cold winter (snow and climate), the warm period can also be premature and lead to abnormal melting.

Connectivity of snow, space, hare and habitat, which is the most important requirement of this sort, is threatened by climate change and various human activities. The rise in temperature accompanied by climate change, the decrease in snowfall amount, the decrease in early snowmelt amount, and the decrease in the number of snow days have serious adverse effects on Hanabaya and its prey snowshoe rabbits. For example, less snowfall means competition with other carnivores is intense. It is not a species often seen in Cryptomeria snow such as Bobcat, it is a very big foot. The seasonal camouflage of snowshoe rabbits (white in winter, brown when no snow falls) may not be able to acclimate quickly enough during seasonal changes. If the fur is still white when the snow melts quickly, animals become more prey and drop the prey's foundation.

Snowfall and snow cover in mountainous areas have a major impact on tree lines and plant communities (Patten and Knight, 1994). Snow melting season affects plants in various ways, such as leaf trait changes, leaf yield changes, shoot growth (Kudo et al., 1999), and flowering (Inouye and McGuire, 1991) . In addition, changes in snowmelt time will change the risk of late spring frost (Inouye, 2000). Degradation of synchronicity associated with biological seasonal events in highlands and lowlands may be problematic for animal species moving between elevation areas (Inouye et al., 2000). For example, Woodchuck is currently hibernating 38 days earlier than the Rocky Mountain 23 years ago (Inouye et al., 2000). In this example

Historically, Wolverine lived in the northern and southern Rocky Mountains, the Sierra Nevada Mountain Range and the North Cascades Mountains, and part of the Midwest and Northeast. Today, we can discover the North Cascade Mountains and parts of Montana, Washington State, Idaho, Wyoming North Rocky Mountains (including the Valley Mountain Range in Oregon State) downstream 48 days. Wolverine. Some people were discovered in Michigan forest, Southern Rocky Mountains in Colorado, Sierra Nevada Mountains in California.
