S. SITES NOT REQUIRING A SURVEY
Some sites are either clearly not appropriate Soiranthes habitat or have
very low potential to be Soiranthes habitat. A survey for Soiranthes is not
required for such sites. Sites below 6,500 feet elevation occurring within
the areas described in Section 3 not requiring a survey for Soiranthes
include:
a. highly disturbed or modified sites such as:
1. highway rights-of-way built on filled and compacted soil
material ;
2. highway rights-of-way built on rock fills, either revegetated
or not revegetated;
3. rock or soil fills with steep backslopes (may or may not be
associated with a road);
4. active construction sites where all vegetation has been
stripped exposing bare soil ;
S. construction sites where construction has been completed within
the last 5 years, but the area has not been revegetated;
6. landscaped and maintained (mowed) bluegrass lawns;
b. upland sites, including, for example:
1. prairie dog towns;
2. short grass prairie;
3. sagebrush or shadscale rangeland;
c. sites entirely inundated by standing water, including, for example,
monocultures of cattails (Tvnha latifolia) or Olney's three-square
(Scir us americanus) . Note that although inundated areas need not be
surveyed, mesic slopes surrounding or adjacent to standing water must be
surveyed if they otherwise meet the criteria indicating potential
suitability as Soiranthes habitat.
d. sites composed entirely of heavy clay soils. However, Soiranthes is
found in areas where more well-drained soils or peat overlie a clay
layer.
e. very saline sites. Soiranthes occurs in alkaline conditions and is
somewhat tolerant of saline conditions. However, it has not been found
in highly saline sites as indicated by dense monospecific stands of
saltgrass (Distichlis s i�icata stricta) .
