Lifeforms Used in Data Presentation
As a tool to enhance understanding of the collected data, the contents of the cover end
summary tables addressing relative cover and species density, as well as the species presence
tables, are organized by lifeform. Categories used include lifeform in the usual sense with an
indication of provenance (Place of originl. Categories used include the following: native
annual and biennial forbs, introduced annual and biennial forbs, native annual grasses,
introduced annual grasses, native perennial forbs, introduced perennial forbs, native perennial
graminoids (includes grasses and grass-like plantsl,introduced perennial graminoids, shrubs (all
of these being native at this site), trees (likewise all native in the study areal, and ferns land
other non-vascular cryptogamsl~
Plant Species Listing
During the course of the field work, a list of all encountered plant species (quantitative plus
incidental observations) was compiled for each vegetation type in both the affected area and
the extended reference area. Scientific names used follow Weber and Wittman {19921;
common names cited may be found in Beetle (19701, Nickerson et al. (19761, or SCS (19791
Cross reference to the substantially revised scientific nomenclature for the flora of Western
• Colorado, as set forth by Weber (19871, may be determined by reference to Weber and
Wittman (19921. References for noxious weeds included Thornton et a1.11974) and Colorado

Photographic Record
Within each vegetation type, representative color photographs were taken to document the
appearance of the vegetation in 1997. Within each photo, a placard identifies the particular
area and sample being illustrated.
Livestock Carrying Capacity. The Seneca II-W South Extension Area herbaceous production
data were used to calculate cattle carrying capacity for each vegetation type. An animal unit
month forage requirement of 900 lbs. of air dry matter, an oven-dry to air-dry weight
conversion factor of 1.11, and an overall proper use factor of 50 percent were used in this
calculation.
General Statistical Design.
Sample adequacy was determined using the following Colorado Mined land Reclamation
