Lost Trail National Wildlife Refuge 6295 Pleasant Valley Road Marion, MT 59925

December 2014

INTRODUCTION Lost Trail National Wildlife Refuge (hereafter Lost Trail NWR) is a large biological reserve (ca. 8,000 acres) in the Northern Rocky Mountains of northwest Montana. Lost Trail NWR is a mosaic of wetlands, foothills grasslands and montane coniferous forest and provides habitat for a large number of native plants. This vegetation, in turn provides habitat for a large number of vertebrate and invertebrate animals. A comprehensive baseline inventory is an essential step in implementing a program to protect biological diversity for several reasons. Results of the inventory can be used to monitor the loss or gain of native and exotic species diversity. Populations of rare or endangered species can be protected from inappropriate management activities, such as livestock grazing, herbicide application and timber harvest. On the other hand, infestations of invasive exotic plants capable of replacing native species can be controlled. Weed control is most efficient when infestations are detected at an early stage. An on-site herbarium is another important product of a floristic inventory. A complete herbarium is an important tool for documenting the baseline survey, for training personnel and can be useful for education projects. Both a herbarium and an annotated checklist are important aids for plant identification. The purpose of this study was to obtain a comprehensive inventory of vascular plants present on Lost Trail NWR. This inventory includes plant collections appropriate for creating a herbarium and an annotated checklist. In addition I documented all locations of noxious weeds and species of concern listed by the Montana Natural Heritage Program.

METHODS I conducted field work May 26-29, June 27-29, July 20, and August 21 in 2005 and May 23-25, June 18-22, July 14-17 and August 16-18 in 2014. I used aerial photos and USGS topographic maps to select ca. 20 areas across Lost Trail NWR that represented the full range of community types. These representative areas were thoroughly surveyed on several of the above dates. I collected specimens of all vascular plant species encountered in flower or fruit and pressed them for herbarium vouchers. The locations of populations of species of concern and noxious weeds were recorded with a Garmin GPS unit. Vascular plant nomenclature follows Lesica (2012).

RESULTS I observed 346 species of vascular plants on Lost Trail NWR during 2005 field work (Lesica 2005) and added an additional 9 species in 2014 for a total of 436 species. I made collections of 387 of these species (Appendix A). Seventy-three of the species encountered were introduced. Fourteen of these species are considered noxious in Montana: Bromus tectorum, Carduus nutans, Centaurea maculosa, Cirsium arvense, Cynoglossum officinale, Hieracium aurantiacum, H. caespitosum, Hypericum perforatum, Leucanthemum vulgare, Linaria vulgaris, Potamogeton crispus, Potentilla recta, Ranunculus acris, and Senecio jacobea. Location information for these noxious weeds is provided in Appendix B. I encountered four species that are currently listed as species of concern by the Montana Natural Heritage Program. Carex amplifolia occurs in permanently wet soil along Pleasant Valley Creek. Hornungia procumbens is uncommon on soil hummocks in a saline wetland on the west end of the refuge. Idahoa scapigera is locally common in vernally moist shallow soil of rock outcrop areas on the west end of the refuge. Silene spaldingii is scattered in rough fescue grasslands on the north and east sides of the refuge. It is also listed as threatened under the Federal Endangered Species Act. Although not currently listed by the Montana Natural Heritage Program, one other species that is rare in Montana also occurs on the refuge. Allium geyeri var. geyeri is common in moist grasslands and meadows. Locations for these species are provided in Appendix C.
