Where severe erosion occurs, 2 weeks without rain result in drought conditions, especially in islands of shallow soil interspersed among the deeper, more fertile soil types. Western white pine (Pinus monticola), ponderosa pine (P. ponderosa), sugar pine (P. lambertiana), and white fir (Abies concolor) are included with other species in mountain portions of the western part of the region. In the east, Fraser fir (Abies fraseri), balsam fir (A. balsamea), and red spruce (Picea rubens) are found in the superhumid region.
