WILDLIFE SPECIES: Anas platyrynchos | Mallard 



GENERAL DISTRIBUTION : 
The mallard has a circumpolar distribution.  It occurs throughout North
America from northern Canada and Alaska south into Mexico and from coast
to coast [12].  It is usually a year-round resident in the central
United States and along the West Coast from Baja to southern Alaska.
The mallard's breeding range is usually in the more northerly parts of
its distribution; it winters in the southern United States and Mexico
[15].

PLANT COMMUNITIES : 
Mallards mostly inhabit wetland plant communities composed of marsh
species such as cattail (Typha spp.), bulrush (Scirpus spp.), smartweed
(Polygonum spp.), sedge (Carex spp.), and (Phragmites spp.).  They also
inhabit brome (Bromus spp.)-wheatgrass (Agropyron spp.) communities
[12].  Mallards may use upland meadows for nesting; plants in these
meadows may include aster (Aster spp.), sowthistle (Sonchus arvensis),
and white-top grass (Scholochloa festucacea) [17].
