Common dandelion is one of the earliest spring bloomers on western rangelands
[134]. It flowers from March to late fall in most states and will
flower throughout the year in warmer areas [126]. General first
flowering dates are from April 28 to May 19, and sometimes earlier in
some locations [116]. By mid-June, common dandelion has reached its maximum
bloom stage, and the seeds from earlier flowering dates are mostly
disseminated. By mid-July, all seeds are disseminated [40].
Reported dates for anthesis in some states are as follows [16,37,100]:
Utah April-July
Colorado April-August
Wyoming May-August
Montana April-September
North Dakota April-June
Virginia February-June
Georgia February-June
Mississippi February-June
Tennessee February-June
Kentucky February-June
Iowa April-June
Alberta June-July
Common dandelion is more palatable to wildlife and livestock in prebloom stages
than in postbloom stages [81]. It is poor to fair in palatability on
ponderosa pine sites throughout the West [85].
Palatability ratings for common dandelion from selected western states are as
follows [37]:

Found in a very wide variety of habitats, but tend to thrive best in disturbed sites such as lawns, paths, waste ground, pastures and road verges. Some microspecies are found in natural or semi-natural habitats, including fens, sand dunes and chalk grassland (3).

Common dandelion is a preferred food of domestic sheep grazing on mountain
meadows [83] and is readily eaten by cattle on rough fescue (Festuca
scabrella) prairies in Alberta [38]. Common dandelion is commonly eaten in the
spring by sharp-tailed grouse [89]. It is a minor component of bighorn
sheep diets in the Upper Yellowstone Valley [63] and is an important
food for pocket gophers on mountain grasslands of Colorado [132].
Common dandelion is an important source of nectar and pollen for bees in Alaska
[96]. Common dandelion is consumed by deer and elk in the spring, summer, and
fall in meadows of the Rocky Mountains [73].
In Yellowstone National Park, common dandelion is an important food for grizzly
bears in summer. Peak use in in June [82]. Leaves, stems, seeds, and
flowers were found in grizzly and black bear scats in Glacier National
Park [65].
In Alberta, black bears browse on earlier phenological stages of
common dandelion (spring and early summer) because of the higher nutrient
quality. Common dandelion is one of the dominant species found in spring bear
scats [52].
During prenesting through incubation of greater prairie chicken broods
(April-May) on the Sheyenne National Grasslands in North Dakota,
common dandelion flowers were one of the primary diet items. Individual fecal
samples contained up to 96 percent common dandelion flowers during April and
May [106].
Common dandelion is one of the favored foods of sage grouse in the spring,
summer, and fall in Nevada. Of all meadow forbs consumed, common dandelion
contributed 82 percent to spring forb diets [40,67].
In British Columbia, deer consumed common dandelion at significantly higher
(P less than 0.05) rates on harvested lodgepole pine sites than on unharvested
sites [28].
