Plants grow in high understory shade with dappled to indirect sunlight. The only female (fruiting) plants were found in areas along the creek where soils are moist to saturated. Numerous male specimens were found in the areas described above. Soils: Soils found in the areas where this collection was made are comprised primarily of Baile silt loam (Ba), Hatboro silt loam (Ha), and Glenelg silt loam, 8 to 15 percent slopes (GgC). Baile silt loam consists of very deep, poorly drained, moderately low to moderately high saturated hydraulic conductivity, soils on upland depressions and footslopes that were formed in local alluvium over residuum from acid crystalline rocks, chiefly mica schist and granitized schist and gneiss; slope ranges from 0 to 8 percent. Hatboro silt loam consists of very deep and poorly drained soils formed in deposited alluvium derived from metamorphic and crystalline rock. They are on flood plains. Slopes range from 0 to 3 percent. Glenelg silt loam, 8 to 15 percent slopes consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. This soil is undifferentiated, mostly poorly drained sandy bottomland soils intermingled with decomposing organic litter and eroded silts and clays due to erosion.

Plants are growing in high understory shade with very little direct sun during most of the day. The remnant woodlands exist mostly along the steep slopes, wetlands and seeps of seasonal and year-round creeks flowing into the Middle Branch White Clay Creek. The woodlands are bordered by numerous housing developments and land converted to meadows; hence there is significant first order edge that is heavily impacted by invasive plant intrusion. Soils: Soils are classified as Glenelg silt loam, 8 to 15% slopes (GgC); this series consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. Saturated hydraulic conductivity is moderately high in the subsoil and moderately high to high in the substratum.

Slopes averaging 60 degrees. Northern and eastern aspects. Localized to bluffs above Iowa River. | Wild material | The native range of Pinus strobus is concentrated in the northeastern United States extending south into the northern edge of Georgia and west to central Minnesota. In Iowa, scattered native populations exist in a few northeastern counties as well as small disjunct populations in central and southeastern counties (Little, 1971). This accession includes genetics from legacy mother trees located in Fallen Rock State Preserve and nearby private property to the south. This area is near Pine Lake State Park, which in 2009 was devastated by a severe hailstorm of "supersized softballs" resulting in significant cambial damage to many species of trees. Damage to the majority of P. strobus specimens throughout the area was so severe that losses occurred immediately. Additional losses in subsequent years continued to occur likely due to additional stress by drought and destruction by bark beetles. The loss of approximately 75% of the P. strobus specimens at Pine Lake State Park was attributed to the 2009 hailstorm prompted efforts to preserve genetics of the white pines here. In 2014, specimens in parts of Pine Lake State Park and also one specimen at Fallen Rock State Preserve were sampled (Carstens, J.) as seeds from specimens ranging in size from 9.25 inches to 31.75 inches d.b.h. However, in 2021, it was determined (Place, A. pers. comm. 24 February 2021 and Carstens, J. & Sherwood, A., pers. observations 1 March 2021) that likely most if not all of the specimens in Pine Lake State Park are planted specimens of unknown origin because P. strobus specimens located at the far east end of Lower Lake (south side) were noted (Carstens and Sherwood, pers. observations 1 March 2021) growing with uncharacteristic associated taxa including Acer saccharinum and Gymnocladus dioicus. Two documents that support these observations includes: 1. Letter signed by Louis H. Pammel (March 25, 1925) to G.B. McDonald of the Iowa State University Forestry Department asking for 200 white pine to be planted at Pine Lake. 2. "Trees to Be Set Out by CCC Workers" in the Eldora Herald (May 9, 1935) referencing the CCC (Civilian Conservation Corps) to plant “1,000 white pines at Pine Lake State Park". Therefore, if obtained, increment borer measurements of specimens that are 94 years of age at present (2014) or older would suggest those as being true, native remnants. Documents that supports the position of remnant specimens at Fallen Rock State Preserve includes: 1. "Picturesque Drives About Eldora", in the Eldora Herald (December 8, 1910) by Clara Estabrook stating "Miss Stoddard of the Iowa Falls school says these (only 11 trees left) are the only native pines (those restricted to the sandstone cliffs) found in Hardin County" and suggested a movement to have them preserved. 2. Forest Flora of Hardin County (1899) by L. H. Pammel stating that the Iowa valley serves as the western limits for white pine and also refers to David D. Owen's geological report from 1839 indicating the occurrences of white pines on the summits of the hills along the Iowa River. In addition, a photo of white pines growing at Steamboat Rock taken by L. H. Pammel was featured on the front page of the 1919 report of the State Board of Conservation titled "Iowa Parks: Conservation of Iowa Historic, Scenic and Scientific Areas." Due to the significant presence of planted specimens of unknown origin in Pine Lake State Park and surrounding private properties, samples collected in 2014 as seeds may likely contain genetics (pollen donors) from specimens of unknown origin. This resulted in the resampling of specimens in 2021 (USFS - IAHA#'s) and 2023 as dormant scions that are from locations known to be untouched by the CCC and thus represent true, remnant specimens. To date (2021), there are only eight legacy specimens left in this population (four specimens at Fallen Rock State Preserve and four specimens at the nearby private property). The largest specimen of P. strobus (Ames 32758) is #IAHA-08 located at (42.395489, -93.091652) measuring (13 May 2018) 35.65" DBH with a height of 78.33' and a spread of 26' totalling 197 points (Rouw, M., personal communication, 8 February 2023). This germplasm represents the southwestern most population of native P. strobus in Iowa and one of the western most populations in North America. Germplasm likely is adapted to Midwestern climatic extremes and potentially very drought tolerant in comparison to other provenances from the eastern or northeastern U.S. | 1921270 | Ames 32758 |
