RESULTS 



Six sites among the twenty-two sites surveyed were found 

 to have significant floristic values or potential for such. 

 These areas are characterized as having known or potential 

 plant species of special concern, or intact plant communities 

 of noteworthy condition or composition. One target species, 

 Eupatorium maculatum, was found at Bluewater Springs Trout 

 Hatchery, with potential habitat for other target species at 

 the same site. Three other sites have potential habitat for 

 target species (Chief Plenty Coups State Park, Cooney State 

 Park, Natural Bridges State Park) that also warrant survey work 

 earlier in the growing season. Two more sites have intact 

 natural vegetation of potential state significance (Pictograph 

 Caves State Park, Water Birch Fishing Access Site) though they 

 have low probability of harboring target species. It is 

 recommended that each of these six sites be revisited and 

 surveyed in greater detail at appropriate dates before weed 

 control treatments are applied in places where their vegetation 

 is native. 



The remainder of this section, beginning on the page 7, is 

 devoted to synopses of each of the sites visited. These 

 include descriptions of the dominant vegetation, assessment of 

 the potential for occurrences of MPSSC, and recommendations for 

 weed control. The most common vegetation at these sites are 

 bottomland types, including woodlands, wetlands, and managed or 

 weedy meadows. There are only a few MPSSC from Table 3 which 

 occur in these habitats. The most obvious two are Eupatorium 

 maculatum and Viburnum lentago, species which could be readily 

 identified at a late season date. Habitats which are more 

 likely to host MPSSC are the dryer uplands which are found at a 

 few sites, especially those close to the Pryor Mountains (e.g. 

 Chief Plenty Coups State Park and Bluewater Springs Trout 

 Hatchery) . The plants in these habitats were mostly senescent 

 at the late season date of these surveys, thus intensive 

 searching for MPSSC was inappropriate. 



Site specific results are summarized in Table 4, noting 

 significant floristic values, also characterizing the habitats, 

 degree of weediness, and overall recommendations.
