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 |

The underlying geology of this area is the Cohansey Formation of middle Miocene origin and comprised of sand, white to yellow with local gravel and clay. It is sometimes locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where it is interbedded with thin beds of ironstone. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. Maximum thickness in the map area is about 60 meters; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion.

The line of [Prunus sp.] goes along a semi-ditch on the side of a dirt road. The plants probably get a bit more water than the plants out in the open forest. The [Prunus sp.] are most often without any other close woody companions. Slope: 0 percent. Aspect: North. Geology: The underlying geology of this area is probably of lower Pliocene age and characterized as the Citronelle Formation. The Citronelle Formation is widespread in the Gulf Coastal Plain. The type section for the Citronelle Formation, named by Matson (1916), is near Citronelle, Alabama. The Citronelle Formation grades laterally, through a broad facies transition, into the Miccosukee Formation of the eastern Florida panhandle. Coe (1979) investigated the Citronelle Formation in portions of the western Florida panhandle. The Citronelle Formation is a siliciclastic, deltaic deposit that is lithologically similar to, and time equivalent with, the Cypresshead Formation and, at least in part, the Long Key Formation (Cunningham et al., 1998) of the peninsula. In the western panhandle, some of the sediments mapped as Citronelle Formation may be reworked Citronelle. The lithologies are the same and there are few fossils present to document a possible younger age. The Citronelle Formation consists of gray to orange, often mottled, unconsolidated to poorly consolidated, very fine to very coarse, poorly sorted, clean to clayey sands. It contains significant amounts of clay, silt and gravel which may occur as beds and lenses and may vary considerably over short distances. Limonite nodules and limonite-cemented beds are common. Marine fossils are rare but fossil pollen, plant remains and occasional vertebrates are found. Much of the Citronelle Formation is highly permeable. It forms the Sand and Gravel Aquifer of the surficial aquifer system. (Source: USGS Florida Geologic Map Data).

Slope: N/A. Aspect: N/A. Soils: The underlying geology of this area is of Middle Miocene, Serravallian origin and characterized as an Cohansey Formation. It is comprised of sand, white to yellow with local gravel and clay. Locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where interbedded with thin beds of ironstone. Unit is a complex of interfingering marine and nonmarine facies. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. In general, the sand is crossbedded, although the style of crossbedding varies significantly with the paleoenvironment. Trough crossbedding predominates, especially in the nonmarine channel fill deposits, and the scale of the crossbeds varies from small to large. Maximum thickness in the map area is about 60 m; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion. There is as much as 18 m of relief along the basal contact. The basal contact is sharp, undulatory, and directly overlain by a thin gravel bed. The Cohansey Formation unconformably overlies the Kirkwood Formation and is found in channels cut down into the Kirkwood. Where the Kirkwood consists of sandy, light-colored sediments, the basal contact of the Cohansey is drawn below crossbedded sediments. Where the Kirkwood consists of dark-colored silty beds, the basal contact is drawn between light-colored Cohansey sediments and the underlying dark-colored sediments. The Cohansey was markedly thinned because of erosion prior to deposition of overlying units in the western and southern parts of the southern sheet. The unit has been extensively eroded and stripped from large areas of the New Jersey Coastal Plain, particularly in the central sheet where outliers are common. In spite of its widespread nature, the Cohansey is poorly exposed because of its loose sandy composition, which causes it to erode easily. (Source: USGS New Jersey Geologic Map Data.) The primary soil type in the location of this collection is classified as Downer loamy sand, 0 to 5 percent slopes, Northern Coastal Plain. Downer Series soils are very deep, well-drained soils that are coarse-loamy, siliceous, semiactive, mesic Typic Hapludults. The upper strata of Downer Series from 0 to 25 cm is dark grayish brown, brown loamy sand that is dry with weak fine granular structure. It is very friable and strongly acid. Lower strata from 25 to 76 cm are yellowish brown single grain, loose loamy sand with few extremely weakly cemented masses of oxidized iron in the lower part. This layer is very strongly acid.

Plants accessed by foot along trails throughout property. | 39.57319800, -74.92908900 | 29 | Plants growing in shade to part-shade over a wide range of habitats from mesic to mesic-dry as well as moist to wetland habitats. The woodlands are mostly deciduous, but also include occasional pine overstory. Slope: N/A. Aspect: N/A. The underlying geology of this area is of Middle Miocene, Serravallian origin and characterized as an Cohansey Formation. It is comprised of sand, white to yellow with local gravel and clay. Locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where interbedded with thin beds of ironstone. Unit is a complex of interfingering marine and nonmarine facies. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. In general, the sand is crossbedded, although the style of crossbedding varies significantly with the paleoenvironment. Trough crossbedding predominates, especially in the nonmarine channel fill deposits, and the scale of the crossbeds varies from small to large. Maximum thickness in the map area is about 60 m; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion. There is as much as 18 m of relief along the basal contact. The basal contact is sharp, undulatory, and directly overlain by a thin gravel bed. The Cohansey Formation unconformably overlies the Kirkwood Formation and is found in channels cut down into the Kirkwood. Where the Kirkwood consists of sandy, light-colored sediments, the basal contact of the Cohansey is drawn below crossbedded sediments. Where the Kirkwood consists of dark-colored silty beds, the basal contact is drawn between light-colored Cohansey sediments and the underlying dark-colored sediments. The Cohansey was markedly thinned because of erosion prior to deposition of overlying units in the western and southern parts of the southern sheet. The unit has been extensively eroded and stripped from large areas of the New Jersey Coastal Plain, particularly in the central sheet where outliers are common. In spite of its widespread nature, the Cohansey is poorly exposed because of its loose sandy composition, which causes it to erode easily. (Source: USGS New Jersey Geologic Map Data.) The primary soil types in the area of this collection is classified as Atsion sand, 0 to 2 percent slopes, Northern Tidewater Area and Downer loamy sand, 0 to 5 percent slopes, Northern Coastal Plain. Atsion Series soils are very deep, poorly drained with moderate to rapid permeability above 70 cm and slower beneath. They are classified as sandy, siliceous, mesic Aeric Alaquods. The upper stratum from 0 to 25 cm is dark gray sand, dry, single grained and lose with many fine roots. It is extremely acid. Lower strata are light gray to dark brown with small percentages of rounded quartzose pebbles and are extremely acid. Downer Series soils are very deep, well-drained soils that are coarse-loamy, siliceous, semiactive, mesic Typic Hapludults. The upper stratum of Downer Series from 0 to 25 cm is dark grayish brown, brown loamy sand that is dry with weak fine granular structure. It is very friable and strongly acid. Lower strata from 25 to 76 cm are yellowish brown single grain, loose loamy sand with few extremely weakly cemented masses of oxidized iron in the lower part. This layer is very strongly acid.

This location was accessed from the east where Miller Avenue meets the fire road, approximately 2 kilometers away. There is no vehicular access to the collecting area. Becoming locally uncommon. This local population is likely to be extirpated in the next 20-30 years. This collector has hiked through this area for more than 35 years and seen dramatic changes in the population. When first observed, Kalmia latifolia was a dominant understory shrub on south- to west-facing slopes beneath a mature forest canopy. Over the years, at least one forest fire has significantly reduced the population, along with a continuing increase in deer populations, resulting in catastrophic browse damage. The absence of a mature forest canopy and periods of drought have almost certainly also resulted in decline of this population. While collecting seed from scattered mature plants well above deer browse levels, this collector also noted that there was virtually no recruitment taking place. | 39.32811200, -77.72242400 | 287 | Plants are growing in part-shade to shade of a deciduous upland, very rocky, and dry forest community. Plants are frequently found growing among boulders, rock outcrops, and steep-slope erosional areas, although, not exclusively.
Soils: The underlying geology of this area is of Late Cambrian to Cambrian origin and comprised of Chilhowee Group; Weverton Formation. This includes interbedded white to dark gray, thin-bedded, micaceous, ferruginous, and sericitic quartzites, phyllites, and white, thick-bedded, ledge-making quartzites; some gray to brown ferruginous quartz conglomerate and purple-banded phyllite.

The primary soil types in the collection area are classified as Dekalb-Bagtown-Rock outcrop complex, 25 to 65 percent slopes. The Dekalb series consists of moderately deep, excessively drained soils formed in material weathered from gray and brown acid sandstone in places interbedded with shale and graywacke. Slope ranges from 0 to 80 percent. Permeability is rapid. Solum thickness and depth to bedrock range from 50 to 100 cm. Flat, subangular or angular, sandstone fragments, 2.5-25 cm across increase with depth and range from 10-60 percent in individual horizons of the solum and from 50-90 percent or more in the C horizon. The amount of rock fragments typically increases with depth. Cobbly, channery, and very stony phases are common. Reaction ranges from extremely through strongly acid.

Soils: The underlying geology of this area is the Cohansey Formation of middle Miocene origin and comprised of sand, white to yellow with local gravel and clay. It is sometimes locally stained red or orange brown by iron oxides and (or) cemented into large blocks of ironstone. Unweathered clay is typically dark gray, but commonly weathers white where it is interbedded with thin beds of ironstone. Sand is typically medium grained and moderately sorted although it ranges from fine to very coarse grained and from poorly to well sorted. Sand consists of quartz and siliceous rock fragments. Some beds are locally micaceous. Maximum thickness in the map area is about 60 meters; however, thickness is difficult to determine because of the irregular basal contact and extensive post-depositional erosion.
