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.

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 |

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 |
