Unique Ecosystem
The area of the Dells provides a mixture of plant communities, including northern and southern oak and pine forests, as well as oak savanna, moist cliffs, and dry cliffs.
The cliffs provide unique niches for plants, some of which are very rare in Wisconsin, including:
- Cliff cudweed (Gnaphalium obtusifolium var saxicola ), which is known in only two places on Earth - in the Dells and in the Kickapoo Valley, grows on protected rock ledges.
- Lapland azalea (Rhododendron lapponicum)
- Round-stemmed false foxglove (Agalinis gattingeri)
- Maidenhair spleenwort (Asplenium trichomanes)
- Fragrant fern (Dryopteris fragrans).
Among the rare animals in the dell are six dragonfly species, including the Royal river cruiser (Macromia taeniolata), six rare mussels and numerous species of birds.

Famous quotes containing the word unique:
“Most women of [the WW II] generation have but one image of good motherhood—the one their mothers embodied. . . . Anything done “for the sake of the children” justified, even ennobled the mother’s role. Motherhood was tantamount to martyrdom during that unique era when children were gods. Those who appeared to put their own needs first were castigated and shunned—the ultimate damnation for a gender trained to be wholly dependent on the acceptance and praise of others.”
—Melinda M. Marshall (20th century)
