The woodlands are primarily deciduous with a few evergreens infrequently mixed. Slope: 15 to 30 percent. Aspect: Northeast. Soil: The primary soil type in the area of this collection is classified as Rockland Series sandstone (Rc). The Rockland series consists of well drained soils formed in loamy colluvium from rotational landslides on slopes of stream valleys and dissections of ground moraines. Saturated hydraulic conductivity is moderate in the upper part of the profile and moderately slow in the lower part. Slopes range from 18 to 70 percent. Some pedons have buried leaves, twigs, and moss. Mass soil movement has left random remnants of soil structure from prior upslope soil development and has buried tree branches, leaves and moss. The upper 0-2 cm of soil contains slightly decomposed organic matter while lower soils layers to a depth of 58 cm are comprised of dark reddish-brown to brown silt loam and are moderately acidic. Below 58 cm the soils are generally dark reddish-brown silt loam and strongly to moderately alkaline. (Source:California Soil Resource Lab/NRCS Official Soil Series Descriptions). Geology: The underlying geology of this area is of Pennsylvanian origin and characterized as Pottsville Formation. It is characterized by light-gray thin to thick-bedded quartzose sandstone and conglomerate containing interbedded dark-gray shale, siltstone, and coal. Mapped on Lookout Mountain, Blount and Chandler Mountains, and Sand Mountain northeast of Blount County, and on the mountains of Jackson, Marshall, and Madison Counties north and west of the TN river.

The upper 0-2 cm of soil contains slightly decomposed organic matter while lower soils layers to a depth of 58 cm are comprised of dark reddish-brown to brown silt loam and are moderately acidic. Below 58 cm the soils are generally dark reddish-brown silt loam and strongly to moderately alkaline. (Source: California Soil Resource Lab/NRCS Official Soil Series Descriptions). Geology: The underlying geology of this area is of Pennsylvanian origin and characterized as Pottsville Formation. It is characterized by light-gray thin to thick-bedded quartzose sandstone and conglomerate containing interbedded dark-gray shale, siltstone, and coal. Mapped on Lookout Mountain, Blount and Chandler Mountains, and Sand Mountain northeast of Blount County, and on the mountains of Jackson, Marshall, and Madison Counties north and west of the TN river.

Curtis ex Chapm. | Florida, United States | NA | | | 2024 | COLLECTED | 11/13/2024 | Yellow River Water Management Area: found in an area where an unnamed unpaved road dead ends near the Yellow River. This unpaved road is accessed from Old River Road to the east near the junction with Shockley Springs Road. Individual plants for this collection were accessed by foot along the edge of the river and associated wetland depressions to the east of the road. The sampling for this portion of the population extends from the GPS coordinates listed above to the northeast where sampling ended at coordinates 30.871238 deg. N, 86.590170 deg. W. | 30.86989400, -86.59218500 | 23 | Plants growing in seasonally inundated swamp habitats associated with the Yellow River and small tributaries. Plants are emergent during portions of the year, primarily during the growing season. During this time of collection, water had receded from the wetlands and the area was relatively dry. Slope: N/A. Aspect: N./A. The underlying geology of this area is the Alum Bluff Group of Miocene origin. It includes the Chipola Formation, Oak Grove Sand, Shoal River Formation, Choctawhatchee Formation and the Jackson Bluff Formation. The formations included in this group are generally defined based on their molluscan faunas and stratigraphic position. Puri (1953) described sediment facies as they relate to the formations of the Alum Bluff Group. These sediments are lithologically distinct as a group, not as individual units. The Alum Bluff Group crops out or is beneath a thin overburden in the western panhandle from river valleys in Okaloosa County eastward to western Jackson County. The Alum Bluff Group consists of clays, sands and shell beds which may vary from fossiliferous, sandy clays to unfossiliferous sands and clays and occasional carbonate beds. Mica is a common constituent and glauconite and phosphate occur sporadically. Induration varies from essentially nonindurated in sands to well indurated in carbonate lenses. Colors range from cream to olive gray with mottled reddish brown in weathered sections. Sand grain size varies from very fine to very coarse with sporadic occurrences of gravel. These sediments generally have low permeabilities and are part of the intermediate confining unit/aquifer system. (Source: USGS Florida Geologic Map Data). The surface soil profile of this area is primarily Kinston, Johnston, and Bibb soils, frequently flooded. Kinston Series soils are poorly drained, alluvial, fine-loamy, siliceous, and acid soils of flood plains. They are peaty to loamy friable, slightly sticky, and slightly plastic in the upper 0 to 7.5 cm of the strata with less sand and more silt-loam in progressively deeper strata. The Johnston Series consists of very deep, very poorly drained coarse-loamy, siliceous, active, acid, thermic Cumulic Humaquepts. The upper 0-75 cm is black, mucky loam that is friable and very strongly acid. The lower strata to 1.75 m are dark gray, loamy fine sand, single grained, loose and very strongly acid.

Shining willow frequents wetland habitats such as swampy lakes, wet meadows and along rivers. Noted for it's extremely shiny, long (e.g. 7-14 cm) leaves with very elongated, acumiate leaf tips and conspicuous, enlarged glands clustered at the end of the petiole. First year branches are very glabrous and bright yellow to bright orange in color. Flowering tends to occur later in spring in comparison to other shrubby willows e.g. Salix discolor, Salix humilis, Salix petiolaris, and Salix eriocephala. Shining willow can often be confused with Salix serissima, but the presence of glands at the base of the petiole, the colorful first year stems (most noticeable in winter) of Salix lucida can be used to separate them. The native distribution of Salix lucida is concentrated in the northeastern U.S. with scattered disjuncts as far west as North Dakota and as far south as the northern tier of counties in Illinois, Indiana, and Ohio (Little, E. L. Jr. 1977). This accession represents genetics from northeastern Wisconsin. Specimens sampled in nature measuring approximately 6' in height with bright orange-yellowish stem colors on most recent year's growth. | 2141551 | Ames 36018 |

L. Jr. 1977). Generally adapted/tolerant to wet soils this species is often found in meadows, fens, swamps, and streambanks. Attractive ornamental characteristics includes early spring, showy flowers and yellow foliage in the fall. Salix discolor provides a critical source of pollen at the beginning of the growing season for a plethora of pollinators and also serves as a larval host to many insect species. Salix discolor are commonly used in the cut flower industry for both their showy catkins and colorful, dormant winter stems. This accession represents genetics from central Wisconsin. Plants in nature measuring approximately 8-10' in height occassionally up to 25' with brown to red-brown stem colors on most recent year's growth. Some genotypes with dense pubescence on stems while others are glabrous. | 2141552 | Ames 36019 |

Native to North America, the native range covers mostly the northeastern US stretching from Maine to western North Dakota and Canada south to central Iowa (Little, E. L. Jr. 1977). Salix petiolaris typically dominates wetland areas including sedge meadows, marshes, riverbanks, and lake shores. Despite favoring wet habitats, it can also be found in dry, upland areas, especially those with high-water tables. However, longevity is generally limited in upland habitats. S. petiolaris, similar to other willow species, responds well to fire, coppicing, or heavy browsing (highly favored by deer) by sprouting new stems close to the crown. In cultivation, plants after five years will encompass a 5' x 5' area due to stems that arch from the main base of the plant. Coppicing of plants to ground level is highly recommended either annually or once every 3-5 years to maintain vigorous growth and plant health. This species requires substantial to full sun exposure and is an excellent choice for streambank stabilizations and windbreaks to reduce soil erosion and drifting snow, respectively. This accession represents genetics from central Wisconsin. Plants noted in nature measuring up to 6' in height. Very densely suckering clumps occassionally reaching up to 10' in diameter. Stem colors on most recent year's growth varied from orange-yellow, red (predominate), to yellow. Petioles are minutely hairy. | 2141554 | Ames 36021 |

Moist deciduous woods. | Wild material | Formerly known as Viburnum trilobum, American highbush cranberry (V. opulus var. americanum) is a North American native shrub that is utilized as an important ornamental and conservation plant that is also harvested as a minor fruit crop (jams/jellies). In nature, this variety is generally found in moist habitats typically along stream banks and swamps where ample moisture is readily available. The native range of V. opulus var. americana is concentrated in the northeastern United States and into Canada (Little, E. L. Jr. 1977). Attractive ornamental characteristics includes showy lacecap flowers in spring and bright red fruits and foliage in the fall. Fruits are tart with a hint of sweetness. The European highbush cranberry (V. opulus var. opulus) is nearly identical to American highbush cranberry other than small glands (<1 mm) on the petiole making the exact determination very challenging resulting in common misidentifications. A major difference between the American and European highbush cranberries is that the European variety produces unpalatable fruit. Recent research has shown that American and European highbush cranberries are genetically distinct and that plants of hybrid origin are uncommon (Tork et al. 2025). Vigorous early spring growth and good tolerance to late spring frosts. Genetic analysis from Tork et al. 2025 confirmed that genetics of this accession represents American highbush Cranberry (Viburnum opulus var. americanum). This accession represents genetics from northeast Iowa and thus the extreme western edge of the species native range. | 1927436 | Ames 32966 |

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 species is relatively tolerant to alkaline and slightly acidic soils and can tolerate both extreme drought and severe flood events. However, well-drained soils are preferred. Genetics of this accession represent the extreme northern edge of the species native range with nuts typically reaching maturity in the last week of September into the first week of October in Iowa. Specimens at the collection site in nature measured ~25 inches DBH, with the largest specimen sampled measuring 40.5 inches DBH. Nut measurements (determined by averaging measurements (mm) from 5 randomly selected nuts off a single mother tree) were variable. Averaged measurements (length/width) recorded from 5 mother trees are as follows: tree #4: 23/15 mm, tree #5: 17/12 mm, tree #6: 26/16 mm, tree #7: 24/15 mm, and tree #8: 24/12 mm. Noted observations of progeny from the 2011 collection noted Tree#4 as having strong resistance to the black pecan aphid, Melanocallis caryaefoliae (Davis)(Hemiptera: Aphidadae). Recollection in 2024 found Tree#4 measuring 42.5" DBH dead as the result of major flooding events in 2013, 2014, and 2019 where floods in 2013 persisted for nearly three months. Flood stage for this population of pecan resides at 538 MSL (Mean Sea Level) which can be compared against data from the Mississippi River Lock and Dam 17 (Flood Events 2009-2024), where water levels were recorded 10-12' above ground level where multiple trees of Ames 30882 have been sampled. | 1865828 | Ames 30882 |
