This accession represents a collection of A. arborea germplasm from the western edge of the species native range, specifically central Iowa. Specimens sampled at the collection site in nature were small to medium understory or woodland edge single and/or multi-trunked trees with a few trees getting close to being deemed as canopy specimens. Bark smooth and light grey in color. Specimens sampled in nature ranging 15-50' in height. Peak flowering occurred on 8 April 2026 with white flowers appearing prior to leaf expansion. Fall colors ranging from orange to orange-red peaking typically at the end of September (central Iowa). Fruits, dark-pink to red, maturing in early June (peak in 2026 occurred on 2 June) averaging 8 mm in diameter, except for mother tree #6 that had rather large fruits at 11 mm in diameter. 2197049Ames 38800

The Hazleton series consists of deep and very deep, well drained soils formed in residuum of acid gray, brown or red sandstone on uplands. Slope ranges from 0 to 80 percent. Permeability is moderately rapid to rapid. Solum thickness ranges from 60 to 120 centimeters. Depth to lithic contact ranges from 1 to 2 meters. Rock fragments of angular sandstone, dominantly less than 25 cm in size, range from 5 to 70 percent in individual horizons. Boulders, stones, flags and channers cover about 5 to 60 percent of the surface of some pedons. Reaction ranges from strongly acid through extremely acid throughout.

The primary soil types in the collection area are classified as Manor loam, 25 to 35 percent slopes, very stony. The soils in the collecting area originated as residuum, weathered from the micaceous schist exposed geology and are generally considered coarse-loamy, micaceous, mesic typic dystrudepts that are very acidic and well-drained. There is a variable depth of soil depending upon the steepness of slopes. Some areas contain significant exposed Peters Creek Schist overlain by a highly decomposed organic mat intermingled with a dense root mat of woody and herbaceous plants.

Deciduous forest. Wild materialThe native range of Populus grandidentata is concentrated througout the northeastern United States with disjunct populations in far south as Kentucky and as far west as central Iowa (Little, E. L. Jr. 1971). Bigtooth aspens are known to be fast-growing trees, making for a quick source of shade in the landscape. As a pioneer species in nature, P. grandidentata is adaptable to a wide range of environments but is considered to be slightly less adaptable than quaking aspen. However, bigtooth aspen is more resistant to canker diseases than quaking aspen (Laidly 1990), potentially making it slightly longer-lived. Bark on big-tooth aspens is generally greyish to greyish-yellow or olive-green compared to quaking aspens where bark is typically white to greyish-white. Leaves and leaf serrations are larger, and the degree of suckering is lower in big-tooth aspens. Both species are well known for their leaves to quake or tremble as the lengthy petioles allow leaves to swivel in the slightest amount of wind. Populus use is well-documented throughout the world and encompasses a wide range of products including energy feedstock, wood chips for pulping fibers, veneer logs, agro-forestry, and phyto-remediation as well as several other environmental applications. Interspecific hybrids of P. grandidentata and P. canescens have superior performance in yield; Hypoxylon canker resistance; and rooting ability compared to pure, N. American aspen genetics. This accession represents genetics acquired from the Des Moines River Valley of central Iowa and considered a disjunct population. P. grandidentata is infrequent to somewhat common throughout parts of the Des Moines River Valley, but very localized. The next closest, native population would be found in Hardin County (Iowa) approximately 50 miles to the northeast near Eldora. In central Iowa, this accession has been noted to have excellent, yellow fall color that typically peaks in mid-October (e.g. 21 October 2015). Fruits usually mature in early May (e.g. 3 May 2017) coinciding with flower initiation on local genotypes of Prunus virginiana. Specimens sampled in nature measuring approximately 60' in height and 16-22" dbh. Due to this accession originating from the western and southern edge of the species native range, it is suspected that this accession would have excellent heat and drought tolerance compared to genetics from areas in the northeastern U.S. 1949856Ames 33965
