several introduced tree species including Populus alba (white 

 poplar) and species of Ulmus (elm) and Salix (willow) which 

 accompany the native cottonwoods (Populus deltoides and P. 

 angustifolia) . The open areas beneath and surrounding the 

 trees have been mowed or leased for hay. Introduced 

 cultivated species which dominate these meadows include Bromus 

 inermis (smooth brome) , Elymus repens (quackgrass) , Phleum 

 pratense (timothy) , Medicago sativa (alfalfa) , Melilotus 

 officinale (sweetclover) , and Trifolium pratense (red clover) . 

 Weedy species in the meadows include Arctium minus (burdock) , 

 Bromus tectorum (downy brome) Capsella bursa-pastoris 

 (shepherd's purse), Cirsium arvense (Canada thistle), 

 Euphorbia esula (leafy spurge), and Lychnis alba (white 

 campion) . Native vegetation at this site is limited to the 

 riverside bars which are dominated by Salix exigua , Equisetum 

 laevigatum, and Phalaris arundinacea. No MFSSC are likely to 

 be found at this site.

Vegetation at this site along the Stillwater River 

 consists of a small floodplain woodland, riverside reeds, and 

 meadows which are mostly mowed and maintained as picnic and 

 camp areas. The woods are dominated by Populus balsamifera 

 (balsam poplar) , with an understory dominated by Prunus 

 virginiana (chokecherry) , Rosa woodsii (rose) , and Clematis 

 ligusticifolia (virgin's bower). Phalaris arundinacea (canary 

 reedgrass) occupies moist ground adjacent to the river. 

 Cultivated species in the meadow include Medicago sativa 

 (alfalfa) , Melilotus officinale (sweetclover) , Phleum pratense 

 (timothy) , and Trifolium pratense (red clover) . A diversity 

 of weeds are found in the woods and mowed area including 

 Arctium minus (burdock), Capsella bursa-pastoris (shepherd's 

 purse) , Cirsium arvense (Canada thistle) , Cyanoglossum 

 officinale ( hounds tongue ) , Glycyrrhiza lepidota (licorice), 

 Lepidium virginicum (peppergrass) , Matricaria matricarioides 

 (pineapple weed) , and Plantago major (plantain) . Surrounding 

 the mowed area is a narrow (and weedy) vestige of the native 

 plant community which presumably once occupied the site. On 

 the flat this is represented by Elymus cinereus (wild rye) 

 dominated grassland (rarely seen during this project) , and 

 above by dry slopes with Artemesia campestris (common 

 sagewort) , A. frigida (fringed sage) , Opuntia polycantha 

 (prickly pear) and Rhus trilobata (skunkbrush) . It is unlikely 

 that any MPSSC occur in these habitats. 



Buffalo Mirage Fishing Access Site 



This area along the Yellowstone River is occupied by 

 floodplain woodlands, mudflats, and gravel bars and weedy 

 roadsides. The woods are dominated by Populus deltoides and 

 P. angustifolia (cottonwoods) with a unique (for this project 

 at least) understory dominant shrub, Rhus trilobata 

 (skunkbrush) . Eleagnus angustifolia (Russian olive) , E.
