[53] Animals have the ability to move at will and thus pose risks of quickly shifting beyond or entirely out of the locales into which they are translocated.
Knowledge of the genetic structure and phenotypic limits of plant species gives insight to the range of climatic shifts a species can endure before migration becomes necessary for a species to avoid climate change-induced extinction or extirpation. [22] [3] Generally, ideal tree habitat ranges are moving poleward for many species.
For the 300 years following the arrival of Europeans, land was cleared, mostly for agriculture, at a rate that matched that of population growth.

California has two high deserts: the Mojave Desert and the Great Basin Desert. The Mojave Desert ecoregion is marked by the presence of Joshua trees. [3] The dry cold Great Basin desert of California consists of the Owens Valley, and is classified into Great Basin shrub steppe by the WWF, [4] and into the Central Basin and Range ecoregion by ...
After numerous California wildfires ravaged the dense forests of California, officials there are set to remove over 10,000 trees after they were damaged by the flames, drought, disease, and age.
California's biggest wildfire of the year — burning through delicate Joshua Tree forests along the California-Nevada border — is an unusual desert blaze being fueled in part by the rapid ...
They are owned collectively by the American people through the federal government and managed by the United States Forest Service, a division of the United States Department of Agriculture. The U.S. Forest Service is also a forestry research organization which provides financial assistance to state and local forestry industry. [15]
