The original range of Asclepias sullivantii was the tall grass prairie, but very little of that habitat remains because of wide spread conversion to farming. [4] In Minnesota it is listed as threatened species, mainly because of habitat loss, and the remaining plants are found on old railroad right ways that preserve small prairie remnants. It ...
Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.
The preserve supports a wide variety of plant and animal species. The bison provide management of the grasses on the prairie. [7] They prefer grasses and sedges, leaving the flowering plants, which support a range of insects and animals. [8] In addition, the bison, reduce the height of the plants, supporting ground dwelling birds.

Prairie restoration is a conservation effort to restore prairie lands that were destroyed due to industrial, agricultural, commercial, or residential development. [1] The primary aim is to return areas and ecosystems to their previous state before their depletion. [2]
Farmers can take odd areas or difficult-to-farm areas out of production as they integrate native plant species into farm fields as contour buffers and edge-of-field filters. [4] In Iowa, most of the rich and fertile soils have been dedicated to corn and soybean crops. Only around 0.1 percent of the original tallgrass prairie remains. [5]

It is native to North America where it is widespread across southern Canada and the United States. It occurs in many types of habitat, including prairie, marshes, dunes, and disturbed areas.
A. textile produces egg-shaped bulbs up to 2.5 cm long. There are no rhizomes. Scapes are round in cross-section, up to 40 cm tall. Flowers are bell-shaped or urn-shaped, about 6 mm in diameter; tepals white or pink with reddish-brown midribs; pollen and anthers yellow.
The contrast between the alkaline soil of the prairies and the acidic soil of the forests causes the sharp delineation in plant types in each region. In the western portion of the prairie, the soil is a brown loess loam over calcareous clay. In hilly areas, the clay is covered by red and yellow sand from the Pliocene epoch. [4]
