The site is 2.5 miles southwest of the town
of Milford. A 3+ acre fen in a beef cattle
pasture owned by William Chaffin. The fen
has been very disturbed by past and present
grazing. The fen is long (approximately
0.25 mile) and skinny. It oocurs below an
escarpment of Salida gravelly sandy loam,
24-40% slopes (73G), an Entic Hapludoll.
The fen occurs on a small terrace above and
southeast of the Little Sioux River. The
soil here is a muck, but it not mapped this
way in the soil survey. It is probably
Balms muck, a Typic Medisaprist. The fen
is on the Des Moines Lobe.
15004- ramets, of which 500+ were flowering
(only about 10%) or fruiting. Hie flowers
were white. B. erecta grew in shallow
(less than 6 cm) spring-fed brooks and in
saturated muck. Associated with Impatiens
