IN REPLY REFER TO:
FWE/CO:ES:Plants-Soiranthes diluvialis (Ute ladies'-tresses orchid)
November 23, 1992
To Whom It May Concern:
The U.S. Fish and Wildlife Service (Service) has established interim
requirements and guidelines for surveys to determine the presence or absence
of the federally threatened plant species Soiranthes diluvialis, Ute Ladies'-
tresses orchid. These guidelines were developed by the Service in
consultation with biologists and ecologists knowledgeable about the species in
order to gain more information about the species, identify potential habitat,
and streamline and standardize survey procedures.
Soiranthes diluvialis occurs in seasonally moist soils and wet meadows near
springs, lakes, or perennial streams and their associated flood plains below
6,500 feet elevation in certain areas in Utah, Colorado, and Nevada. Typical
sites include old stream channels and alluvial terraces, subirrigated meadows,
and other sites where the soil is saturated to within 18" of the surface at
' least temporarily during the spring or summer growing seasons.
The moist soil conditions and vegetation composition of known Soiranthes sites
suggest that wetlands regulated under the Clean Water Act qualify as potential'
Soiranthes habitat. Therefore, delineated wetlands, as well as other drier
sites matching the description above, should be surveyed if they occur in
specified areas in Nevada, Utah, and Colorado.
Surveys are required for appropriate sites below 6,500 feet elevation in the
following areas in Colorado:
a. Boulder and Jefferson Counties;
b. The South Platte River 100 year floodplain and perennial tributaries
from the Front Range as far east as Brush, Morgan County;
c. The Fountain Creek 100 year floodplain and perennial tributaries from
the Front Range to the southern boundary of E1 Paso County;
d. The Yampa River 100 year floodplain and its perennial tributaries
from Steamboat Springs west to the Utah border.
