DISTRIBUTION AND OCCURRENCE
SPECIES: Acer negundo | Boxelder 



GENERAL DISTRIBUTION : 
Boxelder is widespread in riparian and palustrine communities throughout
most of the contiguous United States.  Its range extends from New Jersey
and central New York west through extreme southern Ontario, central
Michigan, northern Minnesota, central Manitoba, central Saskstchewan,
southern Alberta and central Montana, eastern Wyoming, Utah, and
California; and south to southern Texas and central Florida.  It is also
local in New Hampshire, Vermont, Massachusetts, Connecticut, Idaho, and
Nevada.  Boxelder has been naturalized in Maine, southern Quebec, New
Brunswick, Nova Scotia, Prince Edward Island, and in southeastern
Washington and eastern Oregon.  Varieties of boxelder occur in the
mountains of Mexico (Nuevo Leon, San Luis Potosi, and south to
Chihuahua) and in Guatemala [32].

General distribution by variety is as follows [25]:
 
var. negundo -- eastern United States and introduced to eastern
                Washington and Oregon
var. interior -- Rocky Mountains to Arizona and Canada
var. violaceum -- northeastern United States and northern Great Plains
var. texanum -- western Missouri, eastern Kansas and throughout the
                Southeast
var. californicum -- California
var. arizonicum -- Arizona and New Mexico

HABITAT TYPES AND PLANT COMMUNITIES : 
Boxelder is a component of various deciduous forest plant associations
in the Great Plains.  It is associated with the following overstory
dominants:  green ash (Fraxinus pennsylvanica), narrowleaf cottonwood
(Populus angustifolia), plains cottonwood (P. sargentii), aspen (P.
tremuloides), willow (Salix spp.), and bur oak (Quercus macrocarpa).  In
Arizona and New Mexico, boxelder is the overstory dominant in several
high elevation riparian forests.  In much of this species' range there
are no described plant communities.
