The Inventory and Monitoring program of the NPS provides twelve basic inventories for park managers, including lists of species that occur in NPS units. Four hundred seventy two species are certified on the list of vascular plants and vertebrates for Homestead National Monument of America (HOME). Based on a review of the evidence, 441 (93%) species were categorized as Present in Park, and 31 (7%) as Probably Present. One hundred thirty nine species were Unconfirmed or Historic. In addition to documenting the presence of species, reviewers categorized the general abundance of 74 (17%) species and determined residency for all documented vertebrates with the exception of 34 (3 mammals, 31 birds). Fifty three non-native species are documented to occur in the park. Of these are six birds, two fish, one mammal, and 44 vascular plants. Non-native vascular plant species were assigned a NatureServe Invasive Species Impact Rank (I-Rank) based on impact to native species and natural biodiversity. Four of the 44 (9%) non-native plants found on HOME received an overall I-Rank score that included the high category (i.e. most threatening). A total of 59 species are listed by the Nebraska Game and Parks Commission as a species of conservation status. No federally listed species are documented on HOME. Six state listed species include five threatened: massasauga, finescale dace, northern redbelly dace, river otter, and Southern flying squirrel, and one endangered: blacknose shiner. Future inventory efforts are discussed.
