EO ID: 
26533
EO History: 
addition
More potential habitat to survey: 
yes
Suggestions for other areas to survey: 
Additional potential habitat on Mains Ridge between original population observed in 2001/2012 and 2016/2017 observations and between points collected in 2017.
Management needs for this population: 
This population extension is off to the west/south of the Bench Creek Trail, so there is likely very little traffic and should be low disturbance risk.
Additional population comments: 
2016 (Nadine Hergenrider Notes): This report is near a population originally documented on 6/8/2001 and 6/17/2001 (Myers and Hergenrider). The plant was identified as Lewisia kelloggii as the 2001 observations pre-dated the recognition of the plants as a new species (Lewisia sacajaweana) based on DNA evidence. The IFWIS database (January 2016) had additional documentation for the original report location that were made by Kelly Tindall PhD in 2012.
This report extends the location of known occupied habitat to the west along Mains Ridge toward Bull Trout Point. The elevation of observed plants is 8,320 to 8,360 feet. This is a ridgeline location with plants extending off the ridgeline to both the south and toward the steep, northfacing slope (no traversing here!).
The plants ranged in size from a single flower sticking up through the soil to approximately 2 inches in diameter for the largest plants. Overall, an estimated 65% of the plants were blooming, based on obvious blossoms above the soil surface. A small, unidentified bee (pollinator) was observed visiting some of the plants.
While walking up to the ridge, I travelled through the known LESA17 site previously documented in 2001. No LESA17 were observed in the area. My visit was likely beyond the short, seasonal 'emergence' period of LESA17 for this site. Two species commonly found in evidence with LESA17, Allium and Lomatium spp., were also MIA or had dried up. I only observed a few Allium seedheads that had not blown away or been consumed. The Lomatium was dried and desiccated. Both species were observed, green and vital, at the site where LESA was documented today. A fair amount of potential habitat occurs between the original site and where I began to encounter LESA17 today. The two sites have a 600-900 feet difference in elevation. In addition, the intervening habitat was on a steep slope with a south-eastern aspect, which likely has a strong influence on plant phenology and timing of emergence. LESA may very well occur between the 2 sites and needs only be surveyed at the 'right time'.
