Betula pumila L. var. glandulifera Regel
Howard Co.: Oakdale Township T100N R14W Sec
NW4SE4SW4
Site is approximately 6.3 miles NNE of the town of Riceville and
N of a gravel road. A 4+ acre, fair to excellent fen (owned by
Patricia Schumann) on a gentle, NE-facing slope above and SW
of Staff Creek. The fen is raised 1+ meter above the
surrounding land. The site is bordered by crop ground on the
south. The soil here is Muck, moderately deep (221). It is
probably Palms muck, a Terric Medisaprist. The fen is in the
Upper Iowa River watershed and on the Iowan Surface.
B. pumila is the dominant shrub over half of the fen. Ramets
ranged in height from 0.3 to over 3 meters. B. pumila formed
dense thickets in the central part of the fen, becoming more
sparse at the edges of the site. This is one of the 5 largest
populations of B. pumila in Iowa. With Carex lasiocarpa,
Fragaria virginiana, Pycnanthemum virginianum, Salix Candida,
Spiraea alba and Valeriana edulis.
