Trapper Germplasm was selected for superior seedling survival and vigor for use in a variety of conservation applications. Represents genetics of 14 parent plants consisting of 5 seed sources from Montana and Wyoming. Fully adapted to USDA Plant Hardiness Zone 4a and has been observed growing in Zone 3a. Based on the species native range and sources of germplasm used for selection, Trapper snowberry should perform well in most of central and eastern Montana between elevations of 1,950 to 4,000 feet. In northwestern Montana, and eastern Wyoming, it should grow well at elevations between 7,525 to 9,900 feet. It should also perform well in western North Dakota and South Dakota at elevations between 800 to 1,800 feet and in northeastern Colorado at elevations between 3,500 to 8,500 feet. Western snowberry is a perennial, woody, deciduous shrub native to broad areas of the United States. It forms dense colonies or thickets from widely spreading roots and rhizomes. The species is an erect to semi-erect shrub that normally grows 2 to 4 feet tall. The average mature height under wildland conditions is 3 feet. Trapper Germplasm western snowberry reaches 5 feet in height within 6 to 8 years under cultivated conditions with supplemental moisture on productive sites. The fruit are greenish white to white drupes containing two white nutlets that ripen in the fall. | 1684139 | Ames 27794 |

Conservation assessments in North America indicate current (2026) and future concern for the species including Michigan (threatened); Massachusetts (endangered); Ontario Canada (endangered); with NatureServe's 2025 global G5 rank due to genetic swamping and habitat pressure. Red Mulberry seems to be extremely localized to moist, floodplain areas that are high-quality bottomland forests. This accession represents genetics collected from the northwestern edge of the species native range. Specimens sampled in nature displayed the following morphological characters: acuminate leaf tips, impressed veins, pubescent upper and lower leaves, flaky bark (often with tiny pin holes (insect emergence holes)), cordate leaf base, and umbrella-shaped growth habit. M. rubra specimens noted ranged in size from 1"-23" inches DBH with some of the tallest specimens reaching 70' in height. The largest specimen sampled (#172-13) measuring 23.25" DBH. Estimated hundreds, perhaps a thousand specimens of M. rubra noted within the park with very little representation of hybrids or Morus alba. Representation of M. rubra outside of park boundaries is near completely absent and the presence of hybrids and M. alba is extremely evident. Soluble solids content from fruits collected in the wild ranged from 19.0-32.9 degrees Brix. This range of Brix values is likely a result of genetic diversity and also variation in maturity of fruits. Fruits selected for Brix measurements were black in color. The specimen sampled with the highest Brix value was #172-9. All M. rubra specimens noted at time of sampling (12 July 2022) were exhibiting determinate growth compared to local hybrids and M. alba, which were still actively growing with newly emerging leaves. The first study (Adhikari et al. 2026) on the mitogenome of M. rubra utilized sample #172-13 (Ames 35887 Tree #13) reporting 359,221 base pairs (bp) long with 45.8% GC content, comprising 57 genes: 32 protein-coding, 21 transfer, and four ribosomal RNAs. | 2138220 | Ames 35887 |

Gentle slopes and wetlands | Uncertain improvement status | The native range for Osage-orange is reported from eastern Texas, southeastern Oklahoma, southwestern Arkansas, and the northwestern corner of Louisiana (Little, 1971). Historically and presently known for its extreme value as bow-wood and fence posts, Osage-orange represents one of the most widely planted tree species in the lower 48 US states as a living fence starting in the mid-1800's, in the late 1900's as a landscape tree for difficult sites, and most recently its chemical properties. Detailed history of Osage-orange and it's economic uses are well documented (Smith and Perino, 1981 and J. T. Winberry 1979). Osage wood is highly-prized for its use as fence posts (both living and non-living) and durable wood for wood working. Osage is an extremely drought and heat tolerant tree and is recommended for use in USDA cold-hardiness zones 5b or warmer. Although the species is commonly known for its stout thorns and large, globular fruits, the species is dioecious and the degree of thorns on individual genotypes can be extremely variable. This accession represents germplasm from a naturalizing, reproductive population collected in central Iowa (Polk County). Majority of specimens averaged approximately 40-50’ in height with multiple (e.g. 4-5) trunks. Specimens 03-1 and 03-2 were upright in form with tighter branch angles, while 03-10 was the widest spreading of all trees. Some yellow fall color (yellow) was apparent at time of fruit collection (10/05/2016). Size of fruits ranged from 9.00 to 10.75 inches circumference except for tree 03-5 with fruits averaging 7.33 inches circumference. | 1942949 | Ames 33752 |
