Prairie Communities
The prairie communities include various types of natural grasslands and scattered
prairie woodland thickets. The native prairie grasslands, occupying in 1967
about 26 percent of the state, were second only to croplands in proportional
area. Among the major biotic areas, excluding the heavily wooded Turtle Mountain
Region, the proportion of prairie grasslands ranged from a low of less than
1 percent on the Agassiz Lake Plain to a high of 55 percent on the Little Missouri
Slope. Between these extremes, the proportional grassland area varied as follows:
Northeastern Drift Plain, 8 percent; Southern Drift Plain, 9 percent; Northwestern
Drift Plain, 12 percent; Missouri Coteau, 25 percent; Coteau Slope, 36 percent;
and Missouri Slope, 54 percent. The statewide composition of native prairie
from the standpoint of land use was as follows: moderately grazed, 50 percent;
heavily grazed, 27 percent; lightly grazed, 11 percent; nonuse, 8 percent; and
hayed prairie, 4 percent.
Tall-Grass Prairie
Prior to the arrival of the early white pioneers this community was prevalent
throughout the Agassiz Lake Plain Region and also occupied many well-drained
lowland areas in the Prairie Pothole Region. On the Agassiz Lake Plain, it represented
the climax biotic community, whereas in the Prairie Pothole Region, it probably
should be considered as a postclimax. Because of agricultural development, vast
acreages of this habitat have been destroyed, and only a few small remnant tracts
remain at the present time.
The dominant vegetation is composed of tall grasses including such species
as big bluestem, switch grass, Indian grass, and prairie dropseed. Midgrasses
and other grass-like plants of similar stature are commonly associated with
them. These include Kentucky bluegrass, little bluestem, slender wheatgrass,
porcupine grass, mat muhly, fescue sedge, and meadow sedge. Many forbs are
of regular occurrence including smooth camas, red lily, yellow stargrass,
blue-eyed-grass, Canada anemone, prairie cinquefoil, wild strawberry, wild
licorice, meadow parsnip, palespike lobelia, roundhead blazing star, tall
goldenrod, giant goldenrod, smallflower aster, black-eyed Susan, narrowleaf
sunflower, white sage, common dandelion, prairie dandelion, meadow hawksbeard,
and rattlesnake-root.

Eastern Mixed-Grass Prairie
Before the advent of agricultural development, this community was prevalent
throughout the Prairie Pothole Region and also occupied many of the well-drained
lowland areas in the Southwestern Slope Region. During this early period, it
undoubtedly represented the most extensive habitat in North Dakota. From about
1895 to the present time (1972), vast areas of this habitat have been destroyed
and replaced by agricultural croplands. However, fairly extensive tracts still
occur on the Missouri Coteau and in a few localized areas elsewhere. It represents
the climax biotic community in the Prairie Pothole Region but probably should
be considered as a postclimax in the Southwestern Slope Region.
The predominant vegetation is composed of a mixture of mid- and short-grasses
and other grass-like plants of similar stature. Primary species of these types
include prairie junegrass, green needlegrass, needle-and-thread, blue grama,
little bluestem, and yellow sedge. The invading exotic species, Kentucky bluegrass,
also is prevalent in many areas. Secondary species are represented by western
wheatgrass, Canada wild-rye, spike oats, big sandgrass, ticklegrass, porcupine
grass, mat muhly, side-oats grama, Leiberg's panicum, needleleaf sedge, and
threadleaf sedge. Patches of low shrubs are often quite common, particularly
in draws and on east- and north-facing slopes. These are composed chiefly
of wolfberry and, locally, by silverberry.

Western Mixed-grass Prairie
This is the prevalent habitat in the Southwestern Slope Region, and, in this
area, it represents the climax biotic community. It also occurs on many upper
slopes and knobs of the higher morainic hills in the Prairie Pothole Region
where it appears to represent a preclimax community. Although very extensive
tracts of this prairie habitat have been destroyed and replaced by croplands,
about half of the original acreage was still extant in 1967. In many respects,
this type of prairie could be considered as an ecotone between the eastern mixed-grass
prairie and short-grass prairie.
Plate 3. Western Mixed-grass prairie. Slope County, August
1975 (photo by John T. Lokemoen). Dominant plants on this area include western
wheatgrass, needle-and-thread, blue grama, little bluestem, needleleaf sedge,
and threadleaf sedge. Principal breeding birds include the Sharp-tailed Grouse,
Burrowing Owl (formerly common), Horned Lark, Western Meadowlark, Brown-headed
Cowbird, Grasshopper Sparrow, and Chestnut-collared Longspur.
The predominant vegetation is composed of short grasses or grass-like plants
in association with an open growth of midgrasses. Primary species include
western wheatgrass, prairie junegrass, needle-and-thread, blue grama, and
needleleaf sedge. Secondary species are spikemoss, six-weeks fescue, plains
reedgrass, green needlegrass, plains muhly, buffalo grass, little bluestem,
and threadleaf sedge. The more common species of forbs include the following:
White wild onion Narrowleaf blazing-star

Short-Grass Prairie
This habitat, of local occurrence in the Southwestern Slope Region, is largely
restricted to the more elevated portions of the Little Missouri Slope. In this
area it is especially characteristic of the upper slopes and summits of dry
ridges and buttes. It would appear to represent a preclimax community.
The predominant vegetation is composed of short grasses and sedges in association
with a low matted growth of spikemoss. The primary species include spikemoss,
blue grama, needleleaf sedge, and thread-leaf sedge. Occasional, scattered
plants of buffalo grass and needle-and-thread also occur. The more typical
forbs in this type of prairie include sandlily, white wild onion, death camas,
buffalo-bean, purple loco, silverleaf, prickly pear, moss phlox, white beardtongue,
and fringed sage.

Primary intraneous species:
Horned Lark, Chestnut-collared Longspur.
Secondary intraneous species:
Ferruginous Hawk, Marsh Hawk, Burrowing Owl, Killdeer, Long-billed Curlew,
Mourning Dove, Common Nighthawk, Western Meadowlark, Brown-headed Cowbird,
McCown's Longspur.
Extraneous species:
Swainson's Hawk, Golden Eagle, Prairie Falcon, American Kestrel.
Black Sage Prairie
This community may be described as an xeric type of scrub grassland that occurs
in the southern portion of the Little Missouri Slope, chiefly in the western
third of Bowman County and western fourth of Slope County. It is largely restricted
to dry washes and other sites with comparatively sterile clay soils that have
been altered appreciably by water erosion.
It is probable that this community could properly be considered as an ecotone
between short-grass prairie and the northern shrub desert. It is dominated
by an open growth of sagebrush that is composed either of pure stands of black
sage or of mixtures of black sage and silver sage. In the intervening spaces
between shrubs, the vegetation is usually composed of prickly pear in association
with herbaceous vegetation that is dominated by buffalo grass, blue grama,
and needleleaf sedge.

it is associated with scattered silver sage. Prevalent plants occurring in
intervening spaces between shrubs include prickly pear, buffalo grass, blue
grama, and needleleaf sedge. Principal breeding birds are represented by the
Sage Grouse, Lark Bunting, and Brewer's Sparrow.

Sparrow.
Extraneous species:
Swainson's Hawk, Golden Eagle, Prairie Falcon, American Kestrel, Loggerhead
Shrike.
Prairie Woodland Thickets
Isolated woody thickets are scattered throughout the prairie grasslands of the
Prairie Pothole and Southwestern Slope Regions and also occur locally in the
Agassiz Lake Plain Region. These communities develop on sites with comparatively
moist microclimates, including shallow, well-drained depressions and north-
or east-facing slopes of morainic hills, river bluffs, buttes, and badlands.
Most of these communities are dominated by a mixture of small trees and tall
shrubs including such species as Saskatoon serviceberry, hawthorn, wild plum,
choke cherry, and bullberry. These are frequently associated with other woody
plants, the species of which are quite variable from one part of the state to
another. These include golden currant, red raspberry, smooth rose, western rose,
pin cherry, bittersweet, smooth sumac, skunk sumac, poison ivy, silverberry,
and wolfberry.
Another type of prairie thicket is represented by scattered small groves
of quaking aspen. These are especially conspicuous in the northern third of
the Prairie Pothole Region where they are largely restricted to areas of sandy
soil. Aspen groves also are common on deltaic sand areas of the Agassiz Lake
Plain.
