Rare plants 



Field investigaticns should be ccntinued to determine the status of 

 heart-leaved buttercup in the Sv-eet Grass Hills. Bureau of Lard 

 Nfanagement or contract botanists should periodically ccnduct botanical 

 investigations during spring or early summer to determine if heart- 

 leaved buttercup is present in the PACBC. Investigaticns should be 

 conducted prior to any changes in land management policies that might 

 affect the taxcn. If no threats are posed to suitable habitat, the 

 priority for additicnal investigaticns is considered lew. Because 

 access is limited, and the Hills are rugged, a detailed field inventory 

 to document the status of heart-leaved buttercup will require a 

 substantial field effort. The status of springbeauty and twiggy 

 halimolcfcos should be determined following verification of the voucher 

 specirrens. 



Habitat type descriptions 



Habitat types of the Sv,eet Grass Hills have not been quantitatively 

 described. Previous investigaticns by Thcnpscn and Kuijt (1976a) have 

 been qualitative. Although plant ccmmunities in the ?iills resemble 

 seme habitat types described for I-tntana by Pfister et al. (1977) and 

 Mueggler and Stewart (1980), neither study specifically addressed or 

 sampled types within the Hills. Sana similarities are apparent with 

 other prairie mountain ranges in north-central ^tntana; hois'sver, each 

 range ccntains unique types. A detailed quantitative evaluaticn of
