Habitat Characterization and Development of Search Criteria for the Rare Sandhills Lily, Lilium pyrophilum.
The habitat of the rare Sandhills lily, Lilium pyrophilum was studied by comparing 30
plots containing the lily and 30 plots lacking the lily. Field studies measured soil and
vegetation within the plots. Results were used to develop search criteria for this Federal
Species of Concern.
A wetland category status of FACW+ is recommended for L. pyrophilum. Lilium
pyrophilum habitat has an open canopy, dominantly covered by herbs and shrubs found on
side slopes and floodplains. Lilium pyrophilum sites are more species rich. It is not found on
very sandy soils, and can tolerate a range of organic to mineral-organic soils.
Soil within L. pyrophilum plots contained more phosphorus and sulfur, and lower
weight per volume. Site wetness index and site species richness were also higher in L.
pyrophilum plots. Aronia arbutifolia, Pinus palustris, Pinus serotina, Pinus taeda, Smilax
glauca and Sphagnum spp. were significantly more abundant in lily plots. These species can
be used as indicators to help identify potential L. pyrophilum habitat.
