Description

More info for the term: forb

Cow parsnip is a native, perennial forb that grows from 3.3 to 10 feet
(1-3 m) tall [24,26,35] and has broad, flat-topped umbels [33,80]. It
grows from a stout taproot or a cluster of fibrous roots [35,39,72,82].
Leaves are 8 to 20 inches (20-50 cm) long and wide [26,59,82]. The
egg-shaped fruit is 0.32 to 0.48 inch (8-12 mm) long and 0.24 to 0.36
(6-9 mm) wide [26,82].

Key Plant Community Associations

More info for the terms: association, climax, fern

Cow parsnip occurs in a wide variety of forested habitat types, as well
as grassland, shrubland, meadow, alpine, and riparian zones
[3,13,14,34,85].

Cow parsnip is a member of the Pacific silver fir (Abies amabilis)
old-growth forest in Washington [2]. Cow parsnip occurs in whitebark
pine (Pinus albicaulis) communities of Montana [3]. It is a common
understory species in subalpine fir (Abies lasiocarpa) and Engelmann
spruce (Picea engelmannii) habitat types of the Intermountain West
[9,12,20,69]. A subalpine fir/cow parsnip association in Montana, and a
cow parsnip-western coneflower (Rudbeckia occidentalis) community type
in Wyoming are described [14,20]. A climax black hawthorn (Crataegus
douglasii)-cow parsnip habitat type has been described for Washington
and Idaho [13,50]. A climax quaking aspen (Populus tremuloides)/cow
parsnip habitat type has been described for Utah and Wyoming [57,58].

Cow parsnip is found in seral quaking aspen community types in Wyoming,
Idaho, Utah, Colorado, and Montana [7,34,41,57,58,85], and is a dominant
understory species in quaking aspen-dominated communities of Utah,
Colorado, and Montana [41,64]. An quaking aspen/cow parsnip habitat
type has been described for Colorado and Idaho [34,41]. In Canada, cow
parsnip is a member of the subboreal, aspen-dominated spruce zone
[8,11,75].

In eastern Idaho, western Wyoming, and northern Utah, cow parsnip occurs
in a red-osier dogwood (Cornus sericea)/cow parsnip riparian habitat
type [86]. A California false hellebore (Veratrum californicum)-cow
parsnip habitat type has been described in Washington [32]. Cow parsnip
occurs in riparian areas dominated by willow (Salix spp.) throughout the
Intermountain West [19,29,77].

The following publications list cow parsnip as a community dominant or
codominant:

Habitat characteristics

Cow parsnip occurs in a variety of habitats including woodlands, forest
openings, grasslands, and riparian areas such as wet meadows, stream
terraces, alluvial benches, floodplains, and stream and lake margins
[26,28,29,82]. It is commonly found growing in snow-maintained
disclimaxes such as avalanche chutes [28,47,55]. Cow parsnip is a
facultative wetland species [29]; it grows best in moist, shaded areas
[35,59,84] but can also be found in open woodlands and clearings
[35,38,44,56,80].

Cow parsnip grows best on moist to semiwet soils with good drainage
[24,34,44,47]. It grows best on loam and sandy loam soils derived from
limestone and shale, but occurs on clay, clay loam, and gravelly
substrates as well [1531,65].

Elevations for cow parsnip for several states are as follows:

feet meters

Arizona 7,500-9,000 2,250-2,700 [42]
California less than 8,500 less than 2,600 [35]
Colorado 4,700-10,500 1,410-3,150 [15,30]
Montana 4,200-8,500 1,260-2,550 [3,29]
Utah 5,200-9,000 1,560-2,700 [15]
Washington 3,300-5,775 1,000-1,750 [2,9]

General Ecology

Plant Response to Fire

More info for the terms: cover, tree, wildfire

Cow parsnip may benefit from both canopy removal and increased water
availability after tree cover is removed by fire. Cow parsnip had
greater percent cover following both wildfire and clearcutting without
scarification (some stands broadcast burned) than after clearcutting
with scarification [87].

Fire Ecology

More info for the term: succession

Cow parsnip can occur throughout succession in moist or wet subalpine
fir-Engelmann spruce habitat types in Idaho and Wyoming. These habitat
types have estimated average fire-free intervals of about 330 years.
Stands are susceptible to severe burns when drought occurs [91]. Cow
parsnip also occurs throughout succession in communities characterized
by more frequent fire, including quaking aspen [93].

Successional Status

More info on this topic.

More info for the terms: association, climax, cover, frequency, relative frequency

Cow parsnip occurs in seral and climax communities. It is shade
tolerant, but also grows in some open habitats [29,38,41,44,58]. Cow
parsnip is a common understory species in quaking aspen community types,
which are often successional in subalpine forests of the Intermountain
region [4,20,29,41]. Cow parsnip is a member of the red alder (Alnus
rubra) association of Oregon that may be replaced in 30 to 50 years by
black cottonwood or in 30 to 70 years by grand fir (Abies grandis) [31].
The red-osier dogwood-cow parsnip community type of Utah and
southeastern Idaho is an early seral type that colonizes streambanks and
adjacent areas [60]. In the black hawthorn-cow parsnip habitat type of
Washington, cow parsnip can grow as well with or without the black
hawthorn canopy [13]. Cow parsnip occurs in climax aspen forests
throughout the Intermountain West, and in mature to climax subalpine
forests in Wyoming and Montana [14,41,58].

Studies of cow parsnip in clearcuts indicates that its response to
canopy removal is variable. In northern Utah cow parsnip cover was
variable in both control and clearcut stands. Early succession
following a 1974 clearcut of aspen communities (with no slash treatment)
in northern Utah was studied. Percent understory cover of cow parsnip
on clearcuts and uncut controls was [4]:

1973 1975 1976 1977
cut control cut control cut control cut control

0 1.5 1.8 0 0.7 0.3 0.4 0.4

The effects of clearcutting on wildlife habitat were studied in a moist
subalpine forest in central Colorado. Understory cover of cow parsnip
before and after clearcutting (with no slash treatment) was [12]:

before logging years after logging (1978-1982)
(1976) 1 2 3 4 5

cover(%) 0.6 3.1 8.2 8.9 13.3 10.7

In the subalpine fir/queencup beadlily habitat type in northwestern
Montana, cow parsnip occurs in a variety of disturbed and undisturbed
communities. Relative frequency and average canopy cover of cow parsnip
were as follows [87]:

relative frequency % cover

wildfire (35-70 years prior to study) 6 15
clearcut (15-35 years old), slash dozer-piled 4 3
clearcut (15-35 years old), slash not dozer-piled 8 15
old-growth (two types of plots) 3,20 0.5,7.8

Snowchutes are "topographic climax" or disclimax communities that
produce an abundance of grizzly bear foods. In subalpine fir/menziesia,
subalpine fir/queencup beadlily, and subalpine fir/smooth woodrush
habitat types, relative frequency/average precent canopy cover of cow
parsnip in snowchutes was 50/19, 65/13, and 75/6.2, respectively [87].

Regeneration Processes

More info for the term: adventitious

Cow parsnip reproduces by seed [15,38]. For successful germination in
the laboratory, seed should not be stored more than 3 years [72,73].
Some flowers within an umbel only produce stamens, while others are
hermaphroditic. Secondary umbels develop synchronously approximately 10
to 14 days after the primary umbel. Hermaphroditic flower and seed
production may be increased by herbivory [33].

The potential for cow parsnip to regenerate vegetatively is not clear;
Cole and Trull [9] include cow parsnip in a group of plants that
"regenerate rapidly from subsurface adventitious buds."

Management

Management considerations

In Washington cow parsnip is sensitive to grazing and can be eliminated
from steppe vegetation if overgrazed [13]. In Colorado cow parsnip
decreases with grazing [41]. Cow parsnip is sensitive to soil
compaction or severe soil disturbances which may be caused by mechanical
scarification or trampling [9,67].

In high mountain ecosystems of Utah, cow parsnip should be broadcast or
drill-seeded in the fall at 1 to 2 pounds per acre in a mixed seeding
for best forage results [38].

Parsnip webworm, a European-introduced herbivorous insect, feeds on
developing flowers and seeds of cow parsnip. Floral herbivory can
decrease seed production by up to 40 percent and seed biomass 53 percent
[5,33].

Cow parsnip appears to persist or increase after clearcutting [4,12],
but to decrease after soil scarification [87].

Other uses and values

Native Americans of Alaska, British Columbia, the Great Plains, and
Arizona used cow parsnip for medicinal and nutritional purposes
[26,39,42,48]. Native Americans in Alaska ate the inside of stems raw
and boiled the roots to extract sugar [39]. In Arizona, the Apache ate
the young leaves and stems and used the roots to treat epilepsy [42].

Cow parsnip is planted as an ornamental [38].

In the Great Plains cases of dermatitis have been reported in persons
who came in contact with the foliage of cow parsnip [26].

Importance to Livestock and Wildlife

Cow parsnip is a valuable forage species for livestock, deer, elk,
moose, and bear [37,42,43,54]. In West Virginia cow parsnip provides
forage for livestock and deer [10]. Moose in Montana and Yellowstone
National Park eat cow parsnip [40,54]. In low elevation riparian areas
it is an important food for grizzly bear, especially in the spring
[43,52,81,88]. In Glacier National Park, cow parsnip comprised 15
percent of grizzly bear total diet volume, spring through fall, in
1967-1971 and 1982-1985 [43]. In Waterton Lakes National Park, Alberta,
grizzly feeding sites were examined from June to early August; 77
percent of the cropped umbelliferous plants were cow parsnip (stems,
petioles, and blossoms) [28]. Black bear in Alberta cow parsnip in
summer [37].
