Hancock County, Iowa, United States
Locality: Pilot Knob State Preserve (Floating Bog) located approximately 3.66 miles east, southeast of Forest City, area just west of Dead Mans Lake, T97N R23W NW1/4 NW1/4 SE1/4 Sec. 4, Hancock County
Coordinates: 43.2487, -93.5664 (Map it)
Elevation: 406m.
Georeference protocol: Lat/lon determined by GPS
Habitat: Wild Habitat
Environment description: Extremely high-quality remnant floating bog that has never been hydrologically altered. Very diverse habitat.
Number of plants sampled: 70
Associated species: Thelypteris palustris, Lysimachia thyrsiflora (flowering), Carex spp., Cephalanthus occidentalis, Spiraea alba, Ribes americanum, and Salix petiolaris
Slope: 0
Comment: At time of collection (5 June 2020), noted approximately 1,000-2,000 stems across 2-3 acre area. Species only noted in deep sphagnum mat with substantial water. At time of collection (6 June 2020), female catkins were essentially at the very end of dispersal. Estimated time of seed dispersal was likely 7-10 days prior. Sampled 70 specimens throughout area. Most plants with 6-10" of new growth. Only circa 10% of the specimens noted had fruited.

Narrative
Salix pedicellaris is extremely rare in Iowa only found in the northern tiers of counties. Currently listed as a state threatened plant species and thus tracked via the Iowa Natural Areas Inventory Program (Iowa Department of Natural Resources). Only 15 sites throughout Iowa representing 13 counties have documented S. pedicellaris. Since the year 2000, only two reports (observation/herbarium specimen) have documented the species presence in Iowa. Bog willow is a small shrub (<2 meters) typically with few, short stems often hidden amongst sedges. Spreads clonally via suckering and/or layering lending it to be found in stable fen habitats with ample supply of water that see little to no distrurbance. Spring flowering typically occurring in mid-May to early June with fruiting occurring in early June in Iowa. Little to no existance in cultivation. Leaves are rather waxy and significantly repels water. During a growout of original plant material (sampled as cuttings from collection site in nature) at NCRPIS in Ames, Iowa exectued in 2020, a total of 45 genets were identified as female (14) and male (31) on 4 May 2022 and 17 April 2023 during peak flowering.
