DISTRIBUTION AND OCCURRENCE

SPECIES: Betula occidentalis | Water Birch
GENERAL DISTRIBUTION : Water birch is distributed from southern Alaska to southern Manitoba and North Dakota, and south to southern California and New Mexico [31]. It is absent along the Pacific Coast mountain ranges [1]. In California, water birch is found mainly on the east side of the southern Sierra Nevada Mountains, with only a few isolated colonies on the west side [13], and is mostly lacking from the central and northern Sierra Nevada Mountains [39].

These communities often occur as narrow bands adjacent to streams on alluvial terraces throughout the mountainous West in the Douglas-fir (Pseudotsuga menziesii), ponderosa pine (Pinus ponderosa), or Engelmann spruce (Picea engelmannii) zones but may extend well into big sagebrush (Artemisia tridentata) flats [18,30,34,47]. Water birch also grows in riparian communities in the Mojave Desert of California [13]. In North Dakota, aspen (Populus tremuloides)/water birch habitat types are found on relatively steep northeast- to east-facing slopes of upland ravines [16]. Published classification schemes listing water birch as a dominant part of the vegetation in community types (cts), habitat types (hts), riparian site types (rst), or dominance types (dts) are presented below.
